ABSTRACT

PURPOSE@#To retrospectively analyze the clinical outcomes of meniscus repair with simultaneous anterior cruciate ligament (ACL) reconstruction and explore the causes of failure of meniscus repair.@*METHODS@#From May 2013 to July 2018, the clinical data of 165 patients who were treated with meniscus surgery and simultaneous ACL reconstruction, including 69 cases of meniscus repair (repair group) and 96 cases of partial meniscectomy (partial meniscectomy group) were retrospectively analyzed. The exclusion criteria were as follows: (1) ACL rupture associated with fracture, collateral ligament injury, or complex ligament injury; (2) a history of knee surgery; or (3) a significant degree of osteoarthritis. The 69 patients in the repair group were divided into the non-failure group (62 cases) and the failure group (7 cases) depending on the repair effect. Postoperative outcomes of the repair group and the partial meniscectomy group were compared. General conditions and postoperative outcomes of the failure group and the non-failure group were compared. During the median follow-up period of 28 months (range, 4 - 65 months) after the second arthroscopy, postoperative outcomes of seven patients in the failure group were summarized. SPSS 25.0 statistical software was used for statistical analysis. A p value less than 0.05 was considered statistically significant.@*RESULTS@#Seven patients in the failure group who underwent the second arthroscopy were followed up for (30 ± 17.4) months and their postoperative outcomes were summarized. Compared with the partial meniscectomy group, the International Knee Documentation Committee scores of patients in the repair group improved significantly (p = 0.031). Compared with the non-failure group, more patients in the failure group were younger than 24 years (p = 0.030). The median follow-up period was 39.5 months. All patients recovered well after subsequent partial meniscectomy and relieved clinical symptoms. Visual analog scale scores decreased significantly (p = 0.026), and the International Knee Documentation Committee and Lysholm scores improved significantly (p = 0.046 for both).@*CONCLUSION@#The failure rate of meniscus repair in this study was 10.1% (7/69), all of which were medial meniscus tears. However, the surgical outcomes of ACL reconstruction were not affected, and there might be a role for graft protection. Therefore, meniscus retears can be successful treated by performing subsequent partial meniscectomy in patients with repair failure.

ABSTRACT

OBJECTIVE@#To systematically evaluate the clinical efficacy of arthroscopy and traditional incision in the treatment of tibial avulsion fracture of anterior cruciate ligament (ACL).@*METHODS@#From July 2010 to July 2020, clinical comparative trial about arthroscopy and traditional incision in the treatment of ACL tibial avulsion fracture was conducted by using computer-based databases, including Embase, Pubmed, Central, Cinahl, PQDT, CNKI, Weipu, Wanfang, Cochrane Library, CBM. Literature screening and data extraction were carried out according to the inclusion and exclusion criteria, and the quality of the included literature was evaluated by improved Jadad score and Ottawa Newcastle scale (NOS). The operation time, hospital stay, fracture healing time, knee range of motion, postoperative excellent and good rate, complication rate, Lysholm score, International Knee Documentation Committee (IKDC) score and Tegner score were statistically analyzed by Review Manager 5.3 software.@*RESULTS@#Finally, 16 literatures were included, including 1 randomized controlled trial and 15 non randomized controlled trials, with a total of 822 patients (405 in arthroscopy group and 417 in traditional incision group). Meta analysis showed that the operation time [MD=-9.03, 95% CI(-14.36, -3.70), P<0.001], hospital stay [MD=-5.81, 95%CI(-9.32, -2.31), P=0.001] and fracture healing time [MD=-14.61, 95% CI(-17.93, -11.28), P<0.001] in the arthroscopy group were better than those in the traditional incision group. The incidence of complications in arthroscopy group was lower than that in traditional incision group[OR=0.15, 95%CI(0.07, 0.33), P<0.001]. The postoperative excellent and good rate[OR=4.39, 95%CI (1.96, 9.82), P<0.001], knee mobility[MD=6.78, 95%CI(2.79, 10.77), P<0.001], Lysholm score[MD=11.63, 95%CI(4.91, 18.36), P<0.001], IKDC score[MD=7.83, 95%CI(6.09, 9.57), P<0.001] and Tegner score[MD=0.60, 95%CI(0.31, 0.89), P<0.001] in the arthroscopic group were higher than those in the traditional incision group.@*CONCLUSION@#Compared with the traditional open reduction and internal fixation, arthroscopic surgery in patients with ACL tibial avulsion fracture can shorten the operation time, hospital stay and fracture healing time, reduce the incidence of postoperative complications, and obtain good postoperative knee function. It can be recommended as one of the first choice for patients with ACL tibial avulsion fracture.

ABSTRACT

Tibial plateau leveling osteotomy (TPLO) associated to cranial wedge closing ostectomy (CCWO) has been one of the best options to manage cranial cruciate ligament (CCL) disease and excessive tibial plateau angle (TPA) in large dogs, however, the complication rate is potentially high. It is believed that a more robust fixation is necessary to stabilize them and decrease the risk of implant failure. A 6-year-old male American Pit Bull, weighing 36kg, with 90-day history of right hind limb lameness, was diagnosed with CCL disease. Due to the excessive tibial plateau angle (42°), TPLO was associated with a modified CCWO using a double plating technique. A final TPA of 12° was accomplished, and a restricted level of exercises and physiotherapy were recommended. The patient was followed monthly until the fifth month postoperatively, when radiographic bone consolidation and no lameness were observed. By the date of this submission, 3 years after the procedure, the owner has reported no complications. The double plating technique for fixing TPLO and modified CCWO proved to be effective for the treatment of CrCL deficiency in a large dog with an excessive TPA.(AU)


A osteotomia de nivelamento do platô tibial (TPLO) associada à ostectomia modificada em cunha de fechamento cranial da tíbia (CCWO) tem sido uma das melhores opções para tratamento de cães grandes com doença do ligamento cruzado cranial (DLCCr) e ângulo excessivo do platô tibial, mas o índice de complicações é alto. Acredita-se haver necessidade de fixação mais robusta para reduzir as chances de falha nos implantes. Um cão macho, seis anos, da raça American Pit Bull, 36kg, com histórico de claudicação em membro pélvico direito há 90 dias, foi diagnosticado com DLCCr. Devido ao ângulo excessivo do platô tibial (42°), a osteotomia de nivelamento do platô tibial foi associada à ostectomia modificada em cunha de fechamento cranial da tíbia (CCWO) por meio da técnica de placa dupla. No pós-operatório imediato, identificou-se TPA de 12°; exercícios controlados e fisioterapia foram recomendados e a evolução do quadro foi analisada mensalmente até o quinto mês pós-cirurgia. Com 150 dias de evolução, não houve alterações de locomoção e havia ocorrido completa consolidação radiográfica das osteotomias. Até o momento da submissão deste artigo, três anos pós-procedimento, o tutor relata ausência de complicações, via contato telefônico. Portanto, a técnica modificada mostrou-se eficaz no tratamento da DLCCr.(AU)

ABSTRACT

OBJECTIVE@#To bring forward an arthroscopic classification of the popliteal hiatus of the lateral meniscus (PHLM) tears and to assess the effects of arthroscopic all-inside repair with suture hook in management of such injuries.@*METHODS@#This study involved 146 patients who underwent arthroscopic operation because of PHLM tears from April 2014 to October 2017, eliminating the patients who had discoid lateral meniscus. There were 81 males and 65 females, with 54 left knees and 92 right knees. The average ages were (34.7±3.7) years. Among the selected participants, there were 107 patients with anterior cruciate ligament (ACL) injuries, 39 patients with medial collateral ligament (MCL) injuries, and 48 patients with medial meniscus tears. The average preoperative Lysholm and International Knee Documentation Committee (IKDC) scores were 57.7±9.2 and 54.1±8.9, respectively. The arthroscopic classification was based on the extent and degree of PHLM tears and using the arthroscopic all-inside repair with suture hook for such injuries. For the patients associated with ACL injuries, the ipsilateral autograft hamstring tendons use as the reconstruction graft for single bundle ACL reconstructions. The suture anchors were used for treatment of MCL Ⅲ injuries, and the arthroscopic all-inside repair for medial meniscus tears.@*RESULTS@#A total of 146 PHLM tears in 146 patients were divided into type Ⅰ (tears not involved in popliteus tendon incisura; n=86, 58.9%), type Ⅱ (tears involved in popliteomeniscal fascicles; n=36, 24.7%), and type Ⅲ (tears involved in popliteus tendon incisura; n=24, 16.4%). For type Ⅰ, there were three subtypes, including type Ⅰa: longitudinal tear (n=53, 61.6%), type Ⅰb: horizontal tear (n=27, 31.4%), and type Ⅰc: radial tear (n=6, 7.0%). For type Ⅱ, there were also three subtypes, including type Ⅱa: anterosuperior popliteomeniscal fascicle tear (n=5, 13.9%), type Ⅱb: posterosuperior popliteomeniscal fascicle tear (n=20, 55.6%), and type Ⅱc: both tears (n=11, 30.6%). For type Ⅲ, there were two subtypes, including type Ⅲa: horizontal tear (n=9, 37.5%), type Ⅲb: radial tear (n=15, 62.5%). In the follow-up for an average of 15.3±2.6 months, all the patients had done well with significantly improved Lysholm (84.6±14.3) and IKDC (83.2±12.8) scores at the end of the last follow-up relative to preoperative scores (P > 0.01).@*CONCLUSION@#We propose that it is possible to classify lateral meniscus tears at the popliteal hiatus region for three types, which can summarize the injury characteristics of this area. The arthroscopic all-inside repair with suture hook for the PHLM tears can avoid stitching to popliteal tendon or narrowing popliteal hiatus and have satisfactory clinical results.

ABSTRACT

OBJECTIVE@#To evaluate the effects of two different femoral cortical suspension devices (fixation loop and adjustable loop) on tunnel widening and knee function in patients following anterior cruciate ligament reconstruction for 12 months.@*METHODS@#A total of 60 patients who had undergone anterior cruciate ligament reconstruction were included in this study. According to the length of the loop(n)[n= total length of loop-(total length of femoral tunnel-total length of coarse tunnel)] in the rough bone tunnel, the patients were divided into A (adjustable loop was 0 mm in the coarse bone tunnel), B (fixation loop was greater than 0 mm and less than or equal to 10 mm in the coarse bone tunnel) and C (fixation loop was greater than 10 mm in the coarse bone tunnel) groups, of which 11 cases were in group A, 27 cases in group B and 22 cases in group C. In the three-dimensional reconstruction of the knee joint with multi-slice spiral CT, the widening of the bone tunnel in the three groups was compared. At the same time, IKDC, Lysholm and Tegner scores of the patients in the three groups were compared.@*RESULTS@#There were differences in the widening degree of the femoral canal among groups A, B and C, and the median difference of the widening degree of the femoral tunnel 12 months and immediately after the surgery was A < B < C. The difference of femoral canal widening in group A was significantly different from that in groups B and C (P < 0.05).According to the linear regression the relationship between the difference of the width of the femoral canal and the change of the length (n) of the loop in the coarse canal, it was found that there was a linear relationship between the value of n and the difference of the width of the bone canal. With the increase of the value of n, the difference of the width of the bone canal gradually became larger. The median difference of the width of the middle and superior tunnel was negative, while the median difference of the width of the middle and inferior tunnel was positive. During the follow-up, we found that there were no statistical differences in IKDC, Lysholm and Tegner scores among the three groups one year after surgery (P > 0.05).@*CONCLUSION@#Twelve months after surgery, compared with group B (fixed loop group) and group C (fixed loop group), group A (adjustable loop group) had less bone tunnel widening.In groups A, B and C, as the length of the loop in coarse bone tunnel gradually increased, the width of bone tunnel became more significant. At the end of 12 months follow-up after anterior cruciate ligament reconstruction, the medial and inferior femoral tunnel was significantly wider than immediately after surgery, and the medial and superior femoral tunnel had gradually begun to undergo tendon-bone healing. There was no significant difference in knee function scores among groups A, B, and C in the follow-up 12 months after surgery.

ABSTRACT

OBJECTIVE@#To explore the stress distribution characteristics of the graft after anterior cruciate ligament (ACL) reconstruction, so as to provide theoretical reference for the surgical plan of ACL reconstruction.@*METHODS@#Based on 3D MRI and CT images, finite element models of the uninjured knee joint and knee joint after ACL reconstruction were established in this study. The uninjured knee model included femur, tibia, fibula, medial collateral ligament, lateral collateral ligament, ACL and posterior cruciate ligament. The ACL reconstruction knee model included femur, tibia, fibula, medial collateral ligament, lateral collateral ligament, ACL graft and posterior cruciate ligament. Linear elastic material properties were used for both the uninjured and ACL reconstruction models. The elastic modulus of bone tissue was set as 17 GPa and Poisson' s ratio was 0.36. The material properties of ligament tissue and graft were set as elastic modulus 390 MPa and Poisson's ratio 0.4. The femur was fixed as the boundary condition, and the tibia anterior tension of 134 N was applied as the loading condition. The stress states of the ACL of the intact joint and the ACL graft after reconstruction were solved and analyzed, including tension, pressure, shear force and von Mises stress.@*RESULTS@#The maximum compressive stress (6.34 MPa), von Mises stress (5.9 MPa) and shear stress (1.83 MPa) of the reconstructed ACL graft were all at the anterior femoral end. It was consistent with the position of maximum compressive stress (8.77 MPa), von Mises stress (8.88 MPa) and shear stress (3.44 MPa) in the ACL of the intact knee joint. The maximum tensile stress of the graft also appeared at the femoral end, but at the posterior side, which was consistent with the position of the maximum tensile stress of ACL of the uninjured knee joint. More-over, the maximum tensile stress of the graft was only 0.88 MPa, which was less than 2.56 MPa of ACL of the uninjured knee joint.@*CONCLUSION@#The maximum compressive stress, von Mises stress and shear stress of the ACL graft are located in the anterior femoral end, and the maximum tensile stress is located in the posterior femoral end, which is consistent with the position of the maximum tensile stress of the ACL of the uninjured knee joint. The anterior part of ACL and the graft bore higher stresses than the posterior part, which is consistent with the biomechanical characteristics of ACL.

ABSTRACT

OBJECTIVE@#To assess the mid-to-long term clinical outcomes after anterior cruciate ligament (ACL) revision surgery and to analyze their predictors.@*METHODS@#The medical records of 235 patients undergoing ACL revision surgery between Jan. 2001 and Dec. 2015 at Department of Sports Medicine, Peking University Third Hospital were reviewed. Data were collected including demographic information, information related to revision surgery (time and cause of graft failure, date of revision surgery, surgical technique, combined injuries and management, etc.), as well as information related to primary ACL reconstruction (time, cause and mechanism of first-time ACL rupture, date of primary ACL reconstruction, surgical technique, combined injuries and management, etc.). Patients were followed up at least 2 years after revision surgery for clinical outcomes [Tegner score, Lysholm score, and International Knee Documentation Committee (IKDC) subjective knee score]. Post-revision surgeries on the involved knee and the contralateral knee joint were also documented. Multivariate regression model was used to analyze the predictors of clinical outcomes after ACL revision surgery.@*RESULTS@#A total of 166 (70.63%) patients were followed up at a mean of (4.44±2.40) years (2.03-14.63 years). Clinical outcomes improved significantly at the last follow-up from pre-operative level, with the Lysholm, Tegner, and IKDC scores improving from 70.51±21.25, 3.39±1.77, 63.78±15.04 to 88.64±14.36, 4.67±1.739, 80.23±13.31 (P < 0.05), respectively. Three (1.81%) patients experienced infection while 39 (23.49%) patients underwent surgery after revision surgery during the follow-up. Compared with that those occurred during sports, graft failure that occurred during daily activities or due to surgical technical errors that led to poorer clinical outcomes, with the Lysholm, Tegner, and IKDC scores of 9.90 (95%CI: 1.49-18.31), 1.41 (95%CI: 0.10-2.72), 10.35 (95%CI: 0.17-20.54), and 8.53 (95%CI: 1.31-15.75), 1.28 (95%CI: 0.14-2.43), 9.39 (95%CI: 1.03-17.74) lower, respectively. Compared with antero-medial portal, transtibial technique for placement of the femoral bone tunnel showed poorer Lysholm scores of 11.18 (95%CI: 4.73-17.63, P=0.001). Concurrent repair of medial meniscus yielded higher IKDC scores of 11.06 (95%CI: 1.21-20.92, P=0.029) than those with intact medical meniscus. Other factors showed no significant effect.@*CONCLUSION@#ACL revision surgery is able to restore knee stability and improve knee function. Graft failure caused by sports, concurrent repair of medical meniscus and antero-medial portal technique predicts better outcomes after revision surgery.

ABSTRACT

OBJECTIVE@#To investigate the correlation between the quadriceps cross-sectional area (CSA) and quadriceps muscle volume (QMV) at different horizontal levels from the upper edge of the patella, and to determine the best observation position.@*METHODS@#Thigh magnetic resonance imaging (MRI) images of 22 Chinese young men [age: (29±6) years] with anterior cruciate ligament (ACL) rupture were examined. The CSA was measured at 18, 15, and 12 cm above the upper edge of the pate-lla (denoted by CSA-18, CSA-15 and CSA-12 respectively), and the QMV and CSA were determined by semiautomatic segmentation. A curve model was established to estimate QMV. Bland-Altman analysis was performed to determine the confidence limits of the volumes.@*RESULTS@#On the unaffected side, the mean QMV was (1 944.45±323.77) cm3. The quadriceps CSA at the upper edge of the patella at 18, 15, and 12 cm was (80.80±12.16) cm2, (77.53±12.03) cm2, and (72.68±10.51) cm2, respectively. The coefficients of determination (R2), ascertained using curve estimation models, for the 3 positions were 0.819, 0.755, and 0.684 (P < 0.001), and the standard deviations of the volume estimated value (SEE) were 7.4%, 8.7%, and 9.8%. The fitting equations of the three horizontal positions were all good, but the fitting degree of CSA-18 was the highest. The Bland-Altman scatter plot showed that the arithmetic means of the QMV at 18, 15 and 12 cm from the upper edge of the patella 0.8 cm3, -1.1 cm3, and 0.9 cm3 and 95% limits of agreement (LoA) were (-268.8, 270.5), (-315.2, 313.1), and (-355.7, 357.5), respectively. The estimated QMV was in good agreement with the measured value. The difference between the estimated CSA-18 and measured values was the smallest. The results on the affected side were consistent.@*CONCLUSION@#The correlation between QMV and CSA in the young men with the upper edge of patella as baseline was reliable and consistent. Among them, CSA-18 had the highest correlation with the QMV. However, different observation sites could be selected for different injuries of the quadriceps.

ABSTRACT

OBJECTIVE@#To compare the femoral and tibial tunnel positions of anterior cruciate ligament reconstruction using the modified transtibial (MTT) technique and anteromedial (AM) portal technique.@*METHODS@#Between January 2017 and September 2020, 78 patients with anterior cruciate ligament rupture underwent single-bundle reconstruction with the modified transtibial technique in 39 cases (group MTT) and through anteromedial approach in 39 cases (group AM). There were 25 males and 14 females in group MTT, with an average age of (37.0±2.3) years old; 27 males and 12 females in group AM, with an average age of (37.5±2.2) years old. CT scan of the affected knee was conducted one week after the surgery to measure and compare the femoral tunnels positioning (Fx, Fy), tibial tunnels positioning in the frontal plane(Tx1), tibial tunnels positioning in the sagittal plane (Ty1), and tibial tunnels positioning in the axial plane (Tx2, Ty2) in patients undergoing anterior cruciate ligament reconstruction through Mimics software.@*RESULTS@#Three-dimensional CT reconstruction after the surgery showed that the average Fx and Fy were(25.2±2.1)% and (34.9±3.0)% respectively and the Tx1 and Ty1 were (45.5±3.3)% and (44.7± 3.0)% respectively, while the Tx2 and Ty2 were (47.0±3.0)% and (39.9±4.2)% respectively in group MTT. In group AM, the average Fx and Fy were (26.0±2.0)% and (36.1±3.9)% respectively and the Tx1 and Ty1 were (46.5±3.1)% and (45.6± 3.1)% respectively, while the Tx2 and Ty2 were (47.4±2.5)% and (39.6±3.9)% respectively. There were no statistically significant differences in the femoral and tibial tunnels between the two groups (@*CONCLUSION@#Both the MTT and AM technique can achieve good anatomical positioning of the femoral and tibial tunnels, without significant differences in the positioning of the bone tunnels.

ABSTRACT

OBJECTIVE@#To observe the curative effect of one-stage reconstruction of anterior cruciate ligament(ACL), posterior cruciate ligament (PCL) and medial collateral ligament (MCL) in patients with KD-Ⅲ-M knee injury, and to compare the operation time, hospitalization cost and curative effect after arthroscopic reconstruction of PCL with LARS artificial ligament and autogenous hamstring tendon, ACL reconstruction with autogenous hamstring tendon and MCL repair combined with limited incision.@*METHODS@#From March 2016 to January 2019, a total of 36 patients met the criteria of this study. Twenty patients in group A were treated with autogenous hamstring tendon reconstruction of ACL and PCL and repair of MCL, including 17 males and 3 females, with an average age of (34.7±9.2) years old. Sixteen patients in group B with LARS artificial ligament reconstruction of PCL, with an autogenous hamstring tendon reconstruction of PCL and MCL repair as before as group B, including 15 males and 1 female, with an average age of (36.8±8.6) years old. The operation time, hospitalization time and total hospitalization cost were compared between the two groups. The preoperative and postoperative functions of the two groups were evaluated by Hospital for Sepcial Surgery (HSS) score and Lysholm score respectively, and the curative effects were compared within and between groups.@*RESULTS@#All the patients in the two groups were followed up for at least 1 year. There were no complications such as infection and poor wound healing in both groups. There was significant difference in operation time between (120.25±9.55) min in group A and (106.63±8.85) min in group B (@*CONCLUSION@#There was no significant difference in the average hospitalization days between the two groups, but the operation time in group A was longerthan that in group B, and the hospitalization cost in group B was higher than that in group A. There was no difference in HSS score and Lysholm score before and follow-up for a certain period of time after operation.

ABSTRACT

OBJECTIVE@#To investigate and compare the clinical efficacies of remnant-preserving and remnant-non-preserving, remnant-non-preserving remnant segment preserving and remnant root preserving with anterior cruciate ligament reconstruction.@*METHODS@#From March 2014 to December 2017, 204 patients with anterior cruciate ligament (ACL) injuries were treated by single-bundle ACL reconstruction with hamstring tendon autograft. According to the different methods of remnant preservation, the procedures were divided into remnant segment preserving group (A), remnant root preserving group (B), and remnant-non-preserving group (C). There were 37 males and 39 femalesin group A aged from 16 to 43 years old with an average of (28.80±5.41) years old. The time from injury to operation ranged from 2 to 11 weeks with an average of (3.68±1.04) weeks. In group B, there were 39 males and 25 females aged from 18 to 41 years old with an average of (28.42±5.60) years old. The time from injury to operation ranged from 2 to 10 weeks with an average of (3.36±1.68) weeks. In group C, there were 37 males and 27 females aged from 18 to 43 years old with an average of (29.10±6.11) years old. The time from injury to operation ranged from 3 to 11 weeks with an average of (3.54±1.46) weeks. The range of motion (ROM) of the knee was used to assess the range of extension and flextion of the knee at pre-operation and 24 months after operation. Lysholm score and the international knee documentation committee (IKDC) score were used to assess the knee function. The differences among three procedures were judged by comparing among the three groups at 6, 12 and 24 months postoperatively.@*RESULTS@#All incisions got a one stage healing, and no complications, such as vascular injury, nerve damage and articular infect or the like, occurred. All the patients were followed up, and the follow-up duration of group A ranged from 24.00 to 45.96 months with a mean of (35.52±14.40) months;the follow up duration of group B ranged from 27.96 to 48.00 months with a mean of (37.56±10.68) month;and the follow up duration of group C ranged from 24.00 to 66.00 months with a mean of (37.08±13.44) month. There were no significant differences in follow up time among three groups (@*CONCLUSION@#Compared with remnant-non-preserving group, the residual tissue of anterior cruciate ligament is preserved, which is conducive to promote the healing and remodeling of tendon graft and accelerate the recovery of joint function. Proper fixation of residual tissue and restoration of its tension are the key factors affecting the postoperative efficacy.

ABSTRACT

OBJECTIVE@#To study the three-approach and traditional anterior medial technique to establish the femoral tunnel of position, length, and coronal angle and the early efficacy of anterior cruciate ligament reconstruction.@*METHODS@#Through retrospective research, from December 2018 to June 2019, a total of 36 patients diagnosed with simple anterior cruciate ligament tear and undergoing surgery were collected. All patients had a clear history of knee sprains and were divided into two groups. A group of 16 patients, including 11 males and 5 females, with an average age of (30.13±6.54) years and an injury time of 7 to 60 (30.19±15.78) days, three-approach technique was used to drill the femoral tunnel to reconstruct the anterior cruciate ligament. Another group of 20patients, including 15 males and 5 females, with an average age of (30.80±8.60) years, and an injury time of 7 to 60 (27.35±15.50) days, the traditional anterior medial approach was used to drill the femoral tunnel to reconstruct anterior cruciate ligament. CT 3D reconstruction technique was used to evaluate the femoral tunnel and the knee joint function was evaluated by Lysholm score of the knee joint.@*RESULTS@#All patients achieved primary healing after the surgical incision. No femoral tunnel fracture, vascular and nerve damage, difficulty in graft passage during the operation, and venous thrombosis occurred. All 36 patients were followed up on an outpatient basis, with a follow up period of 9 to 15 (12.00±2.83) months. Three-dimensional CT reconstruction was used to evaluate the femoral tunnel of the patients. The position of the femoral tunnel was described using the quartile method as the three-approach group:the lower (27.83±1.97) % of the femoral condyle and the posterior (25.57±3.20) %;the traditional approach group:the lower (28.38±3.21) % of the femoral condyle and the posterior (26.23±3.20) %. Bone tunnel length, three-approach group:(35.20±5.52) mm in total length, (23.20±2.07) mm in thick bone tunnel;traditional approach group:(34.60±4.26) mm in total length, (22.56±2.50) mm in thick bone tunnel. Coronal plane angle, three-approach group:(47.93±5.98) °;traditional approach group:(41.78±6.62) °. Knee joint Lysholm score, three-approach group:48.67±4.18 before surgery;97.00±2.48 at last follow up;traditional approach group:49.75±5.33 before surgery, 97.30±2.68 at last follow up, there were significant differences before and after surgery, no significant statistical difference between two groups.@*CONCLUSION@#The positions of the femoral tunnel drilled by the two methods were within the range of the anatomic stop of the anterior cruciate ligament, and there was no statistical difference. Compared with the traditional anterior medial approach, the coronal plane angle of the femoral tunnel drilled by the three-approach approach is relatively large, and there were no statistical differences in the length of the tunnel, the early postoperative effect of the two surgical methods, and the operation time. But the three approach has a wider and clearer vision. In addition, the knee flexion angle required for drilling the femoral tunnel during surgery is significantly smaller than that of traditional approach technology, which reduces the difficulty of surgery.

ABSTRACT

OBJECTIVE@#To compare the clinical outcomes of arthroscopic anterior cruciate ligament (ACL) reconstruction (ACLR) with a tibialis anterior allograft (TAA)versus hamstring tendon autograft (HTA) after 10 years follow-up.@*METHODS@#A clinical data of 107 patients who underwent arthroscopic ACLR with a single bundle tendon between March 2007 and March 2010 was retrospectively analyzed. Among the patients, 48 patients were reconstructed with a tibialis anterior allograft (TAA group), including 26 males and 22 females, ranging in age from 16 to 38 years, with a mean of 27.2±6.2 years;59 patients were reconstructed with a hamstring tendon autograft (HTA group), including 31 males and 28 females, ranging in age from 16 to 40 years, with a mean of 28.0±7.6 years. The preoperative tibial anterior displacement and knee joint function, as well as knee joint stability, tibial anterior displacement and knee joint function at 10 years after operation were observed. Lachman test was used to evaluate the forward joint stability and pivot shift test to evaluate the rotational stability of the knee;KT-2000 side-to-side difference (SSD) was used to measure tibial anterior displacement;International Knee Documentation Committee(IKDC) score and Lysholm score were used to evaluate knee function.@*RESULTS@#The incisions of both groups were healed by first intention, and no early complications occurred after operation. All patients were followed-up 10 to 13 years, the mean time was 11.7 years. There was no graft failure were found during the follow up period. The KT-2000 SSD of the TAA group and the HTA group at ten years after operation were 1.9±0.7 and 1.8±0.6 respectively, which were significantly improved than 8.8±0.9 and 8.6±1.0 preoperatively(@*CONCLUSION@#The TAA and HTA have equal long term effect in ACL reconstruction, doctors and patients can choose the graft according to the actual situation.

ABSTRACT

The anterior cruciate ligament (ACL) reconstruction mostly relies on the experience of surgeons. To improve the effectiveness and adaptability of the tension after ACL reconstruction in knee joint rehabilitation, this paper establishes a lateral force measurement model with relaxation characteristics and designs an on-line stiffness measurement system of ACL. In this paper, we selected 20 sheep knee joints as experimental material for the knee joint stability test before the ACL reconstruction operation, which were divided into two groups for a comparative test of single-bundle ACL reconstruction through the anterolateral approach. The first group of surgeons carried out intraoperative detection with routine procedures. The second group used ACL on-line stiffness measurement system for intraoperative detection. After that, the above two groups were tested for postoperative stability. The study results show that the tension accuracy is (- 2.3 ± 0.04)%, and the displacement error is (1.5 ± 1.8)%. The forward stability, internal rotation stability, and external rotation stability of the two groups were better than those before operation (

ABSTRACT

Dada la creciente popularidad de las actividades deportivas, el número de roturas del ligamento cruzado anterior (LCA) y lesiones meniscales ha aumentado en particular en niños y adolescentes. El manejo de estas lesiones es desafiante debido las fisis abiertas. Por un lado las opciones de reconstrucción del LCA incluyen técnicas: transfisarias, extra-articulares y intraepifisarias. Por otro lado se han descrito diferentes técnicas de reparación meniscal: "all-inside", "inside-out" y "outside-in". Estas tiene como objetivo lograr la cicatrización meniscal, evitando los efectos adversos de la meniscectomía. Presentamos un reporte de caso de un adolescente de 14 años con una rotura completa del LCA y una lesión del cuerno posterior del menisco interno que fue sometido a una reconstrucción transfisaria del LCA y a una reparación meniscal "inside-out".


With the raising popularity of sporting activity, the number of anterior cruciate ligament (ACL) ruptures and meniscal tears has increased in particular in children and adolescents. Management of these injuries is challenging due to open growth plates. On the one hand the ACL reconstructions options includes: transphyseal, extra-articular and epiphyseal-only techniques. On the other hand there have been described different meniscal repair techniques: "all-inside", "inside-out" and "outside-in". These aim to achieve meniscal healing, avoiding the adverse effects of meniscectomy. We present a case report of a 14-year adolescent with an ACL complete rupture and a posterior horn tear of the medial meniscus who underwent an ACL transphyseal reconstruction and a "inside-out" meniscal repair.

ABSTRACT

OBJECTIVE: Analyze return to sports and related factors after primary anterior cruciate ligament reconstruction. METHODS: Observational descriptive study. 173 patients operated by the same surgeon and standardized technique (patellar autograft) who answered a questionnaire at least 12 months post procedure were included. Questionnaire included Subjective IKDC, Tegner activity level (Pre and Postoperative) and questions elaborated by the group. RESULTS: Mean age was 30.8 years, 85% were men, 73% practiced soccer and median postoperative IKDC was 71. Follow up until questionnaire response was 28 months. Males had a better return to sports than females (70% vs 48%, p » 0.037). Tegner preinjury level was 5 vs 4.3 postoperative, (p < 0.001). Return to sports was 67% according to Tegner scale and 66% by self-assessment. Return to similar previous activity level was 57% by Tegner scale but 24% by direct questions. Of those patients, 51% have fear of reinjury and 26% by reasons other than knee or surgery. We didn't find association between meniscal injuries and return to sports rate. Patients with chondral injuries had lower rates in return to sports (35% vs 60%, p » 0.002). Subjects that returned to sports had higher IKDC scores (73.5 vs 64.3, p < 0.001). CONCLUSIONS: We found 67% return to sports and 57% to the preinjury level. Positive return to sports factors were male sex, absence of chondral injury and better functional outcome. Psychological factors such as fear of injury is frequent in patients who don't achieve previous levels of activity.


OBJETIVOS: Analizar el retorno deportivo y factores asociados tras la reconstrucción primaria de ligamento cruzado anterior (LCA). MÉTODOS: Estudio observacional descriptivo. Se incluyeron 173 operados entre 2014 y 2017 por el mismo cirujano, los cuales contestaron un cuestionario al menos 12 meses después de la cirugía. El cuestionario incluye IKDC subjetivo, Tegner activity level (pre y post operatorio) y preguntas de elaboración propia. RESULTADOS: La edad promedio es 30,8 años, el 85% son hombres, el 73% practicaba fútbol y la mediana del IKDC fue 71. La media de meses hasta responder el cuestionario fue de 28 meses. Tegner pre-lesión promedio fue de 5 vs 4,3 postoperatorio, p < 0,001. Según la escala Tegner el 57% retorna al mismo nivel previo, sin embargo, de acuerdo con el cuestionario propio solo el 24% lo haría. De ese subgrupo, el 51% tiene temor a lesionarse de nuevo y el 26% reporta razones no relacionadas a la rodilla. No encontramos asociación entre lesiones meniscales y la tasa de retorno. Aquellos que retornan tienen menor prevalencia de lesiones condrales (35% vs 60%, p » 0,002). Los pacientes que retornaron tuvieron un IKDC superior (73,5 vs 64,3, p < 0,001). El sexo masculino tiene una tasa de retorno de 70% vs 48% de su contraparte femenina (p » 0,037). CONCLUSIONES: El 67% retorna al deporte y el 57% lo hace al mismo nivel. Factores positivos relacionados al retorno fueron sexo masculino, ausencia de lesión condral y mejor resultado funcional. Factores psicológicos con el miedo a lesionarse de nuevo son frecuentes en pacientes que no recuperan el nivel previo.

ABSTRACT

Resumen: Introducción: Cuando existe una lesión en ambas rodillas del ligamento cruzado anterior (LCA), el cirujano tiene la opción de reconstruir ambos de manera escalonada o simultáneamente. Existen algunos reportes y series de casos donde se realiza la reconstrucción simultanea del LCA. En este trabajo, presentamos el caso y resultado con la reconstrucción simultánea de LCA. Caso clínico: Hombre de 40 años de edad sin antecedentes de importancia. Presentaba una lesión bilateral de LCA, por lo que se le realizó cirugía sin torniquete con autoinjerto de isquiotibiales, fijado con endobutton y tornillos de interferencia. En el postoperatorio, la marcha y un programa acelerado de rehabilitación física se inició de manera inmediata. A cinco meses de seguimiento, el paciente se encuentra sin dolor y con arcos de movilidad completos y simétricos, sin complicaciones reportadas. La escala funcional de WOMAC de 35 en el preoperatorio bajó a 6 en la última consulta. Hasta el momento, la reconstrucción simultánea del LCA fue un procedimiento seguro; sin embargo, sabemos que nuestro seguimiento es muy corto para emitir alguna otra aseveración.


Abstract: Introduction: When there is injury to both knees of the anterior cruciate ligament (ACL), the surgeon has the option to reconstruct both in a staggered manner or simultaneously. There are some reports and case series where the ACL is performed simultaneously. In this manuscript we present a case and the result with simultaneous reconstruction. Clinical case: 40-year-old male with no history of importance with bilateral ACL injury; torniquet-free surgery was performed with autograft of hamstrings, secured with endobutton and interference screws. In the postoperative period, and an accelerated program of physical rehabilitation were immediately initiated. At five months of follow-up the patient is painless, with full, symmetrical knee range of motion. No complications reported. WOMAC's functional scale dropped from 35 preoperative to 6 in the last visit. Until now, simultaneous reconstruction of the LCA was a safe procedure; however, we know that our follow-up is too short to make any other assertions.

ABSTRACT

OBJECTIVE@#To investigate the clinical effects of individualized repair and reconstruction surgery for multiple ligament injury and dislocation of knee joint based on stage classification diagnosis.@*METHODS@#From January 2018 to January 2019, 42 patients with multiple ligament injury and dislocation of the knee joint were treated. There were 27 males and 15 females, aged from 30 to 63 (47.35±11.90) years old, including 17 left knees, 23 right knees and 2 bilateral knees. All patients with multiple ligament injuries and dislocations of the knee joint were classified by stages and improved Schenck diagnosis. Among them, 23 cases were in acute stage (≤3 weeks), 19 cases were in old stage (>3 weeks), 27 cases were type Ⅲ dislocation and type Ⅳ dislocation. There were 9 cases of dislocation and 6 cases of type Ⅵ dislocation. The corresponding repair methods such as closed manipulation and open release reduction, direct suture of ligament, anchor suture, bone penetrating suture, and routine ligament reconstruction were performed. The corresponding "progressive progressive excitation" rehabilitation program was adopted after the operation. After 2, 4, 6, 8 weeks and 3, 6, 9, 12 months after operation, the outpatient consultation and evaluation of knee joint function and stability were completed. The knee joint stability, excellent and good rate, disability rate and complication rate were compared before and after operation. Internation Knee Documentation Committee (IKDC) grade, IKDC subjective score, Lysholm score and Tegner score were used to evaluate knee joint function.@*RESULTS@#All patients completed the outpatient follow-up and follow-up on schedule. All patients had gradeⅠwound healing, 4 patients had lower extremity venous thrombosis after operation, and there were no serious complications after anticoagulant treatment; 5 patients with common peroneal nerve injury were treated with release surgery and active postoperative rehabilitation, and neurological function gradually recovered. At 12 months after operation, the muscle strength of the affected limb reached grade Ⅴ and the active and passive range of motion recovered to more than 120 degrees. In the acute stage, the IKDC subjective scores were 20.46±12.61, 22.58±16.83, 0.71±1.14, 69.55±16.57, 77.73±15.14 and 3.14±1.67, respectively. One year after operation, IKDC subjective score was 67.04±19.07, Lysholm was 74.87±14.58, Tegner was 3.06±1.70, and 6 of them were grade A. After 12 months, the knee function scores of all patients were significantly improved compared with those before operation(@*CONCLUSION@#According to the classification of multiple ligament injuries and dislocations of the knee joint, the corresponding surgical repair and reconstructiontreatment were adopted, and the corresponding rehabilitation program was adopted after the operation. The patients achieved good clinical treatment effect 12 months after operation, and the patients' satisfaction was high, which improved the excellent and good rate of treatment and reduced the disability rate.

ABSTRACT

Resumen: Introducción: Las lesiones del LCA se encuentran dentro de las lesiones ligamentarias más frecuentes. Esto ha llevado al desarrollo de diferentes técnicas quirúrgicas para recuperar la estabilidad de la rodilla. Material y métodos: Estudio clínico, aleatorizado, ciego comparando técnicas de reconstrucción de LCA con Un Haz y «U-Dos¼ mediante escalas clínicas y artrometría con KT-1000 y Pivot Shift Meter. Resultados: De 36 pacientes, 52.94% fue sorteado para la técnica de Un Haz y 47.06% para «U-Dos¼. En 11.76% de los pacientes se presentó un desplazamiento mayor a 11 mm en la rodilla afectada con KT-1000. En 8.82% se mostró un desplazamiento anterior igual en ambas rodillas. Un paciente presentó un desplazamiento anterior mayor posterior a la cirugía de reconstrucción con la técnica de Un Haz, pero con mejoría en las escalas clínicas. En las mediciones de Pivot Shift se encontró una diferencia en el desplazamiento mayor a los 4,000 m/s en el eje de las X tras la técnica de Un Haz en comparación con la rodilla sana calculando integrales, mientras que con U-Dos la diferencia fue menor de 600 m/s. En el eje de «Y¼ se encontró una diferencia > 3,500 m/s entre la pierna sana y la lesionada, la cual disminuye a menos de 2,000 m/s tras la reconstrucción mediante técnica de U-Dos. Conclusiones: A lo largo del estudio se han encontrado diferencias en la evolución de los pacientes que indican que la reparación mediante la técnica de U-Dos tiene mejores resultados al lograr recuperar la estabilidad anteroposterior y rotacional del miembro afectado.


Abstract: Introduction: ACL injuries are found within the most common ligament injuries. This has led to the development of different surgical techniques to restore knee stability. Material y Methods: Clinical study, randomized, blind comparing ACL reconstruction techniques with One Band and «U-Two¼ using clinical scales and arthrometria with KT-1000 and Pivot Shift Meter. Results: Of 36 patients, 52.94% was drawn for the One Band technique and 47.06% for «U-Two¼. 11.76% of patients had a displacement greater than 11mm in the affected knee with KT-1000. 8.82% showed an equal anterior displacement on both knees. One patient had a major previous displacement after reconstruction surgery with the one band technique, but with improvement on clinical scales. Pivot Shift measurements found a difference in displacement greater than 4,000 m/s on the X axis following the One Band technique compared to the healthy knee calculating integrals, while with U-Two the difference was less than 600 m/s. On the Y axis a difference of > 3,500 m/s was found between the healthy and the injured leg, which decreases to less than 2,000 m/s after reconstruction using U-Two technique. Conclusions: Differences have been found throughout the study in patient evolution, indicating that repair using the U-Dos technique has better results in recovering the anteroposterior and rotational stability of the affected limb.
