Study on clinical characteristics and surgical methods of bucket-handle meniscal tears / 中国修复重建外科杂志

OBJECTIVE@#To summarize the clinical features, surgical methods, and prognosis of bucket-handle meniscal tears (BHMTs), and provide guidance for clinical treatment.@*METHODS@#The clinical data of 91 BHMTs patients (91 knees), who met the selection criteria and were admitted between January 2015 and January 2021, was retrospectively analyzed. There were 68 males and 23 females. Age ranged from 16 to 58 years with an average of 34.4 years. The injury was caused by sports in 68 cases, traffic accident in 15 cases, and falls or sprains in 8 cases. There were 49 cases of left knee injury and 42 cases of right knee injury. The time from the onset of symptoms to the admission ranged from 1 day to 13 months (median, 18 days), including >1 month in 35 cases and ≤1 month in 56 cases. Medial BHMTs occurred in 52 cases and lateral BHMTs in 39 cases. There were 36 cases with ACL rupture and 12 cases with discoid meniscus. The knee extension was limited more than 10° in 55 cases. According to the condition of meniscus injury, the meniscus suture with Inside-out combined with All-inside techniques (54 cases) or meniscoplasty (37 cases) under arthroscopy were selected. ACL reconstruction was performed in all patients with ACL rupture with autogenous hamstring tendon. Postoperative complications were observed. International Knee Documentation Committee (IKDC) score, Lysholm score, and Tegner score were used to evaluate knee function, and clinical failure was recorded.@*RESULTS@#Two patients developed intermuscular venous thrombosis, which improved after oral anticoagulant therapy. No vascular injury, postoperative infection, joint stiffness, or other complications occurred in all patients. All patients were followed up 24-95 months, with a median of 64 months. A total of 12 cases (13.19%) failed the operation and were re-operated or given oral anti-inflammatory analgesics and rehabilitation therapy. At last follow-up, IKDC score and Lysholm score of 91 patients significantly increased when compared with those before operation ( P<0.05), while Tegner score significantly decreased ( P<0.05). The above indexes of patients treated with meniscus suture and meniscoplasty were also significantly different from those before operation ( P<0.05).@*CONCLUSION@#BHMTs occurs mostly in young men and is one of the important reasons for the limitation of knee extension after trauma. Arthroscopic meniscus suture and meniscoplasty can obtain good effectiveness according to individual conditions of patients. But the latter can better preserve the shape and function of meniscus, and theoretically can obtain better long-term outcomes, which needs to be confirmed by further research with larger sample size.

AMR Sign - An Arthroscopic S-shaped Fold Signifying Adequate Medial Meniscus Repair

@#Introduction: The preferred management of medial meniscus tears has notably moved from meniscectomies towards repair. With a higher volume of meniscal repairs being done all across the world with every passing day, the lack of an objective and definitive sign suggesting the adequacy of its repair is daunting. The purpose of our study was to introduce a unique and novel arthroscopic sign formed after adequate repair of the medial meniscus, the AMR (Adequacy of Medial meniscus Repair) sign. We hypothesised that it is not only the objective end point for repair, but can also form the indicator for excellent clinical, functional, and radiological outcome even in the long term. Materials and methods: This was a multicentric, prospective study initiated by the corresponding author, and the findings validated subsequently by the other authors. Overall, it included 804 patients of isolated medial meniscus tear operated with arthroscopic all-inside technique between January 2014 and December 2017. Patients were segregated into three groups based on whether an S-shaped curve in the free, inner edge of the medial meniscus sign was formed post-repair, lost after further tightening, or not formed upon subjective completion of repair. All the patients were followed-up and evaluated based of medial joint line tenderness, McMurray’s test for medial meniscus, IKDC score, WOMET score, and radiologically using an MRI at the terminal follow-up. Results: The mean terminal follow-up was 42.34±4.54 months. There was significant (p<0.01) improvement in all patients at the terminal follow-up post-surgery, irrespective of the group. The group in which AMR sign was formed and maintained showed a significantly better functional outcome on terminal follow-up as well as lower failure rates compared to the other two groups. Conclusion: AMR sign is an S-shaped fold at the inner, free edge of medial meniscus, formed after an adequate repair of isolated medial meniscus tear, as viewed on arthroscopy. It is an objective sign denoting regained integrity of the collagen architecture of the medial meniscus following repair. It is also a reliable indicator of excellent long term functional, clinical, and radiological outcome and also lower failure rates in patients after arthroscopic medial meniscus repair.

Comparison of Outcomes Between All-Inside SingleBundle and Double-Bundle Anterior Cruciate Ligament Reconstruction: A Retrospective Study

@#Introduction: ACL rupture is the most common type of knee injury. The All-inside ACL reconstruction procedure features some distinguished components including closed-socket tunnels with less bone expulsion, double suspensory fixation, and smaller incisions. We aimed to compare the outcomes between the All-inside Single-bundle and the Double-bundle ACL reconstruction techniques. Materials and methods: This study was a retrospective study which analysed the patient-reported and the clinical outcomes on patients who underwent ACL reconstruction between January and December 2020 at Dr Kariadi General Hospital Semarang, Indonesia. We compared the patientreported and the clinical outcomes at 6- and 12-month follow-ups between the All-inside Single-bundle and the Double-bundle groups. The patient-reported outcomes were determined using the IKDC and Tegner-Lysholm scores while the clinical outcomes included the measurement of Thigh Circumference, Single Hop test, Anterior Drawer test, Lachman test, Range of motion, and the patient’s level of return to sport. Results: A total of 24 subjects were divided into two groups, namely the All-inside Single-bundle and the Double-bundle groups, consisting of 12 subjects in each group. Most of the subjects were male in both groups, including 9 (75%) subjects in the All-inside Single-bundle group, and 11 (91.67%) subjects in the Double-bundle group. The mean age of the subjects were 25.75±7.57 years old in the Allinside Single-bundle group, and 24.5±6.87 years old in the Double-bundle group. In terms of the side of the knee that suffered the most injuries in both groups were the right knees. The result of the patient-reported outcomes using IKDC and Tegner-Lysholm scores showed no statistically significant differences in both groups at 6- and 12-month follow-ups (p=0.864; p=0.293 and p=0.589; p=0.233, respectively). The results of clinical assessments at 6- and 12-month follow-ups also showed no statistically significant differences in both groups. Conclusion: Our study showed no significant differences in the patient-reported and the clinical outcomes between the All-inside Single-bundle and the Double-bundle ACL reconstruction techniques at 6- and 12-month follow-ups.

Abstract Introduction The anterior cruciate ligament (ACL) provides posteroanterior stability to the knee. The incidence of ACL ruptures is 1/3,000. The gold standard in diagnosis is diagnostic arthroscopy. Arthroscopic reconstruction offers the best results. Objective To verify that the functional results in postoperative patients of arthroscopic reconstruction of the ACL with the all-inside® technique are good to excellent using the Lysholm functional evaluation scale. Material and methods The scores obtained on the Lysholm scale prior to surgery were reviewed at two, six, 10 and 15 postoperative weeks of patients diagnosed with ACL lesion undergoing arthroscopic reconstruction using the all-inside® technique from August 1st, 2016 to August 1st, 2017. The results of the Lysholm functional scale were statistically compared using the Friedman test, and the range of mobility, with the ANOVA and Tukey tests. Results A sample of 34 patients was recruited. The average obtained in the Lysholm scale was 87.82 at the 15th postoperative week. There was a statistically significant difference in score of the Lysholm scale and the range of mobility when comparing the score prior to surgery with 10 and 15 postoperative weeks. Conclusions All-inside® technique is an adequate therapeutic option for patients with ACL tears that allows good results in short-term follow-up.

The Results of All-Inside Meniscus Repair Using the Viper Repair System Simultaneously with Anterior Cruciate Ligament Reconstruction

BACKGROUND: Meniscus tears are commonly associated with anterior cruciate ligament (ACL) ruptures. It is essential to repair meniscal tears as much as possible to prevent early osteoarthritis and to gain additional stability in the knee joint. We evaluated the results of arthroscopic all-inside repair using the Meniscal Viper Repair System (Arthrex) on meniscus tears simultaneously with ACL reconstruction. METHODS: Nineteen out of 22 patients who were treated with arthroscopic all-inside repair using the Meniscal Viper Repair System for meniscus tear associated with ACL rupture were evaluated. ACL reconstructions were performed at the same period. The mean follow-up period was 16.5 months (range, 12 to 24 months). The clinical results of the meniscus repair were evaluated by symptoms (such as catching or locking), tenderness, effusion, range of motion limitation, and the McMurray test. Clinical success was defined by negative results in all five categories. The Hospital for Special Surgery (HSS) score was evaluated. Objective results were evaluated with secondary look arthroscopy or magnetic resonance imaging (MRI). The MRI results were categorized as completely repaired, incompletely repaired, and failure by Henning's classification. The results of second-look arthroscopy were evaluated with the criteria of meniscal healing. RESULTS: The clinical success rate was 95.4% and the HSS scores were 93.9 +/- 5.4 at the final follow-up. According to Henning's classification, 15 out of 18 cases showed complete healing (83.3%) and two cases (11.1%) showed incomplete healing. Seventeen out of 18 cases that underwent second-look arthroscopy showed complete healing (94.4%) according to the criteria of meniscal healing. Only one case showed failure and the failure was due to a re-rupture at the sutured area. Complications of ACL reconstruction or meniscus repair were not present. CONCLUSIONS: The results demonstrate that arthroscopic all-inside repair using the Meniscal Viper Repair System is an effective treatment method when it is performed simultaneously with ACL reconstruction.

Clinical Results of the Accelerated Rehabilitation Program after Meniscal Repair using the RapidLoc Device / 대한정형외과학회잡지

PURPOSE: The purpose of this study was to evaluate the clinical results of the accelerated rehabilitation program after performing meniscal repair using the RapidLoc device, and we wanted to investigate the incidence of complications related to using the RapidLoc device together with the accelerated rehabilitation program. MATERIALS AND METHODS: We performed a retrospective review of a consecutive series of meniscal repairs that were done by single surgeon with using the RapidLoc meniscal repair device. An accelerated postoperative rehabilitation program followed, and this was independent of whether anterior cruciate ligament (ACL) surgery was also performed. The Lysholm and IKDC (International Knee Documentation Committee) activity scores, the clinical examination findings and the adverse events were recorded for all the patients. In addition, using Barrett's criteria, a repaired meniscus was considered healed if there was no joint line tenderness, effusion or a negative McMurray's test at the latest follow-up. RESULTS: At follow-up, the mean IKDC activity score was 3.38 (1.75 preoperatively), the Lysholm score was 91.8 (48.7 preoperatively). Clinical success occurred for 30 repairs (93.7%) at the time of the last follow-up. Two patient had tenderness on joint line palpation and intermittent effusion, so theses repair were considered failure according to our criteria. There was no specific complication related to the RapidLoc device. CONCLUSION: Our results show that accelerated rehabilitation program after arthroscopic meniscal repair with using the RapidLoc device provided a high rate of clinical meniscus healing and this appeared to be safe and effective.

Results of Arthroscopic All-Inside Sutures in Medial Meniscus with Concomitant Anterior Cruciate Ligament Reconstruction / 대한정형외과학회잡지

PURPOSE: To evaluate the clinical results of arthroscopic all-inside suture using 2 posteromedial portals for medial meniscus posterior horn (MMPH) tears by second-look arthroscopy in patients received concurrent anterior cruciate ligament (ACL) reconstruction. MATERIALS AND METHODS: From May 1997 to June 2001, 78 MMPH tears were treated with arthroscopic all-inside sutures with concurrent anterior cruciate ligament (ACL) reconstruction. Among these 39 patients were availablefor follow-up evaluation by second-look arthroscopy. All MMPH tears were repaired using the arthroscopic all-inside suture technique using 2 posteromedial portals. Second-look arthroscopy was performed on average 19 months (range 6 to 40 month) after the ACL reconstruction and meniscal repair. Meniscus healing status was defined and classified. According to the Henning classification, they were divided into complete healing, incomplete healing, and failure. Tear size, type and location were analyzed and compared with healing category. We determined clinical criterias for success in meniscal status as; (1) no positive among 4 clinical objective parameters: joint line pain and tenderness, locking or catching, recurrent effusions, and positive McMurry test; and (2) complete healing of all-inside sutured meniscus during second-look arthroscopy. RESULTS: Of 39 knees assessed by second-look arthroscopy, 32 (82.1%) showed complete healing, 6 (15.4%) incomplete healing without any positive findings of clinical symptoms. Furthermore, all in the incompletely healed group showed complete healing of the posterior horn, which was sutured by allinside suture, whereas incomplete healing was observed at the junctional areas between all-inside and inside-out sutures, mainly at the posteromedial corner. So the overall success rate was 97.4% (38/39) for all-inside suture healing. The one (2.6%) patient with clinical failure revealed a retear of the repaired site, and subsequent subtotal menisectomy was performed. KT-2000 arthrometry showed that sagittal knee laxity was less than 2 mm (Average 1.5 mm, SD 0.72) in all reconstructed knees. The average knee scores, Lysholm knee score and HSS score, at final follow up were 95.5 and 96.5, respectively. As expected, small, longitudinal, and more peripheral (red-red zone) tears resulted in a higher healing outcome. CONCLUSION: Accurate repair with arthroscopic all-inside vertical suture using a suture hook, resulted in a high healing rate even in large and complex vertical tears. Arthroscopic all-inside meniscal suturing may be an optimal treatment for medial meniscus posterior horn tear greater than 1 cm during concurrent anterior cruciate ligament reconstruction.
