Arthroscopic Confirmation of Femoral Button Deployment During Posterior Cruciate Ligament Reconstruction.

Posterior cruciate ligament (PCL) ruptures are uncommonly seen in knee ligament injuries. Cconservative treatment is often suitable for isolated tears with mild-to-moderate posterior knee laxity (grades I or II). However, surgical intervention is indicated for symptomatic grade III or multiligament knee injuries. PCL reconstruction has experienced continuous development due to the progress made in arthroscopic techniques and instruments. Abnormal positioning and tensioning of the femoral button result in multiple complications such as residual laxity, loss of quadriceps muscle strength, and joint stiffness. In this Technical Note, we describe direct arthroscopic visualization of the femoral button deployment in PCL reconstruction technique, and we discuss its importance to prevent complications related to button malposition.

Secondary Meniscectomy Rates and Risk Factors for Failed Repair of Ramp Lesions Performed at the Time of Primary ACL Reconstruction: An Analysis of 1037 Patients From the SANTI Study Group.

BACKGROUND: Studies evaluating secondary meniscectomy rates and risk factors for failure of ramp repair are sparse and limited by small numbers and heterogeneity. PURPOSES/HYPOTHESIS: The purposes were to determine the secondary meniscectomy rate for failure of ramp repair performed using a posteromedial portal suture hook at the time of anterior cruciate ligament reconstruction (ACLR) and to identify risk factors for secondary meniscectomy. It was hypothesized that patients who underwent ACLR combined with a lateral extra-articular procedure (LEAP) would experience significantly lower rates of secondary meniscectomy compared with those undergoing isolated ACLR. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: Patients undergoing primary ACLR and ramp repair between 2013 and 2020 were included in the study. Final follow-up for each patient was defined by his or her last appointment recorded in a prospective database (with a study end date of March 2023). The database and medical records were used to determine whether patients had undergone secondary meniscectomy for failure of ramp repair. Survivorship of ramp repair (using secondary meniscectomy as an endpoint) was determined using the Kaplan-Meier method. Multivariate analysis was used to investigate possible risk factors. RESULTS: A total of 1037 patients were included in the study. The secondary meniscectomy rate after ramp repair was 7.7% at a mean final follow-up of 72.4 months. Patients without combined ACLR + LEAP were >2-fold more likely to undergo a secondary medial meniscectomy compared with those with combined ACLR + LEAP (hazard ratio, 2.455; 95% CI, 1.457-4.135; P = .0007). Age, sex, preoperative Tegner score, and time between injury and surgery were not significant risk factors for failure. CONCLUSION: The rate of secondary meniscectomy after ramp repair performed through a posteromedial portal at the time of primary ACLR was low. Patients who underwent isolated ACLR (rather than ACLR + LEAP) were >2-fold more likely to undergo a secondary medial meniscectomy for failure of ramp repair. Additional risk factors for failure of ramp repair were not identified.

Effect of Lateral Extra-Articular Procedures Combined With ACL Reconstruction on the Rate of Graft Rupture in Patients Aged Older Than 30 Years: A Matched-Pair Analysis of 1102 Patients From the SANTI Study Group.

BACKGROUND: Clinical studies have demonstrated significant advantages of combined anterior cruciate ligament (ACL) reconstruction (ACLR) and lateral extra-articular procedures (LEAPs) over isolated ACLR in terms of reducing graft rupture and reoperation rates. However, most of the published studies have included young patients, and no studies have focused on patients aged >30 years. PURPOSE/HYPOTHESIS: The purpose of this study was to compare the outcomes of isolated ACLR versus ACLR + LEAP at midterm follow-up in patients aged >30 years. The hypothesis was that patients who underwent combined procedures would experience significantly lower rates of graft rupture. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Patients >30 years of age who underwent primary ACLR + LEAP between January 2003 and December 2020 were propensity matched at a 1:1 ratio to patients who underwent isolated ACLR. A retrospective analysis of prospectively collected data was performed to determine graft rupture rates, knee stability, reoperation rates, and complications. Graft survivorship was assessed using the Kaplan-Meier method. Risk factors associated with the occurrence of graft failure were analyzed using a Cox proportional hazards model. RESULTS: Two groups of 551 patients each were included in the study, and the mean follow-up was 97.19 ± 47.23 months. The overall mean age was 37.01 ± 6.24 years. The LEAP group consisted of 503 (91.3%) patients who had anterolateral ligament reconstruction and 48 (8.7%) patients who had a Lemaire procedure. Overall, 19 (1.7%) patients had graft failure: 15 (2.7%) in the no-LEAP group and 4 (0.7%) in the LEAP group (P = .0116). The risk of graft failure was significantly associated with the absence of LEAP (31 vs 12; hazard ratio, 3.309; 95% CI, 1.088-10.065; P = .0350) and age between 30 and 35 years (hazard ratio, 4.533; 95% CI, 1.484-13.841; P = .0080). A higher rate of reoperation for secondary meniscectomy was found in the no-LEAP group (5.6% vs 2.2%; P = .0031). CONCLUSION: Patients aged >30 years who underwent combined ACLR and LEAP experienced a >3-fold lower risk of ACL graft failure compared with those who underwent isolated ACLR. Furthermore, the group without LEAP experienced a higher rate of secondary meniscectomy.

Ultrasound-guided electrocoagulation of neovascularisation for persistent patellar tendinopathy in athletes: a cohort study of 25 patients with a mean follow-up of 5 years from the SANTI Study Group.

Background: Patellar tendinopathy (PT) is a common condition characterised by persistent patellar tendon pain and dysfunction, particularly in athletes. Neovascularisation is frequently observed in the PT and is associated with increased pain. Ultrasound-guided electrocoagulation of neovascularisation has emerged as a minimally invasive alternative treatment for recalcitrant PT. Hypothesis/purpose: The purpose of this study was to evaluate the clinical outcomes of ultrasound-guided electrocoagulation of neovascularisation in athletes with persistent PT. Study design: Case series; level of evidence, IV. Methods: A retrospective analysis of prospectively collected data was performed on 25 athletes who underwent ultrasound-guided electrocoagulation of neovascularisation for recalcitrant PT. Clinical outcomes including complications, reinterventions and patient-reported outcome measures were recorded. Comparisons between variables were assessed using χ2 test or Fisher's exact test for categorical variables and Student's t-test or Wilcoxon test for quantitative variables. Results: 25 patients were included in the final analysis. 96% returned to their preoperative activity level at a mean of 3.8 months. At a mean follow-up of 5 years 4% did not receive significant benefit from electrocoagulation therapy. Significant improvements were observed in outcome measures, including the Victorian Institute of Sport Assessment Questionnaire for Patients with Patellar Tendinopathy, Kujala score, modified Blazina score and Visual Analogue Scale for pain. Conclusion: Ultrasound-guided electrocoagulation of neovascularisation for persistent PT in elite athletes resulted in a low complication rate, a high rate and rapid return to sport and a significant improvement in outcome measures.

Intraneural Lipoma: A Rare Cause of Median Nerve Compression.

Intraneural lipomatous tumors are rare lesions that mostly affect the upper extremities. These slowly growing tumors can have a serious neurological and functional impact when they reach a significantly large size. We report herein a case of a 53-year-old female who presented with a large median nerve intraneural lipomatous tumor causing compression-related signs. She was treated with monoblock excision of the tumor that was completely residing between the median nerve fibers. At her last follow-up, no median nerve deficits were recorded, and the patient went to full resolution.

Chronic Rupture of Pectoralis Major Muscle Repair: A Surgical Case Report.

Introduction: Pectoralis major injury is a rare injury. Its incidence increases with sports related activities. Early diagnosis is essential to obtain a satisfactory functional outcome. We present in this paper a case of 39-year-old male patient presenting with missed chronic the right pectoralis major muscle injury treated with anatomic surgical reinsertion of the muscle tendon to the humerus. Case Report: A 39-year-old male bodybuilder patient felt a snap in his right dominant shoulder while performing bench press. Diagnosis was missed by two physicians and right shoulder MRI confirmed the diagnosis of pectoralis major muscle injury. Reinsertion of the PM muscle tendon using suture anchor was done through deltopectoral approach. Shoulder immobilization for 1 month followed by passive and active range of motion exercises results in satisfactory cosmetic and functional outcome. Conclusion: PM muscle rupture affects mainly young male weightlifters. Loss of the anterior axillary fold is pathognomonic for PM injury. Magnetic resonance imaging of the chest wall is the gold standard examination for the diagnosis. Acute surgical repair (<6 weeks) is recommended to obtain good or excellent cosmetic and functional outcomes. Reconstruction showed lower strength and patient satisfaction; however, results were still significantly better than non-operative treatment reserved for patients with partial tears, muscle belly irreparable damage, and elderly patients with medical comorbidities whom operative treatment is not indicated.

Septic Metallosis after Unicompartmental Knee Replacement: A Case Report and Literature Review.

Introduction: Metallosis following prosthetic hip and knee replacement is a well-known complication. However, unicompartmental knee arthroplasty (UKA) metallosis is rare. In this paper, we report a case of septic metallosis after unicompartmental knee replacement and we review the literature for the available treatment options. Case Report: A 83-year-old female patient presented with left periprosthetic knee infection on the top of unicompartmental knee prosthesis three months after septic endocarditis that was treated with anti-biotherapy. Surgical exploration showed severe infected metallosis due to chronic polyethylene wear reaction; hence, management consisted of total synovectomy and debridement of all metallic debris and two stage revision. Conclusion: Metallosis is a well-known complication after prosthetic hip and knee replacements. However, in UKA, it remains a rare complication where only few cases were reported in the literature.

Isolated Trapeziometacarpal Joint Dislocation With Five Years of Follow-up: A Case Report and Review of the Literature.

Isolated trapezio-metacarpal joint dislocation is a rare injury. Despite being simple to reduce, there is not yet a consensus regarding how to secure the reduction, the type of immobilization, and the postoperative protocol. Herein, we present a rare case of pure trapezio-metacarpal joint dislocation without any associated fractures that was treated with closed reduction and intermetacarpal fixation, six weeks of immobilization, and an early rehabilitation protocol.

Floating-Variant Medial Elbow Dislocation: A New Classification System.

Floating-variant elbow dislocation is a newly updated term used to describe several associations of fractures around the elbow and elbow dislocation that are still not adequately classified due to their rarity. Being extremely rare, only a handful of case reports are found in the literature describing this condition. Most of these papers described cases associated with the posterior or posterolateral direction of elbow dislocation, wherein each author has treated the fracture differently. The decision of surgical treatment, the order of fixation, the material used, and the need for ligamentous repair are all questions that are yet to be answered. We present herein a unique new variant of floating medial elbow dislocation in a 13-year-old female that was successfully treated by closed reduction of the elbow, open reduction of the distal humerus fracture, and orthopedic treatment of the radial shaft fracture.

Acute Osteochondral Fracture of the Metatarsal Head: A Report of Two Cases and Review Of Literature.

Traumatic osteochondral fractures of metatarsal heads are rare injuries and are scarcely reported in the literature. Their classification and modalities of treatment remain unclear. Herein, we report two cases of traumatic fractures of the articular surfaces of the metatarsal heads in two young patients in which two different modalities of surgical treatment were used to achieve anatomic reduction and congruity of the metatarsophalangeal joints. The postoperative period was uneventful, and good functional and radiological outcomes were achieved in both patients. In this report, we review the literature for similar cases and discuss the available treatment options and their associated complications.

Minimally Invasive Osteosynthesis of Intraarticular Calcaneus Fracture Augmented by Femoral Head Allograft: A Retrospective Study.

AIM: The aim of this retrospective study is to report the results of minimally invasive osteosynthesis when used for the treatment of intraarticular calcaneus fracture. This old technique is regaining popularity recently with the multiple advances added by different institutes when it is used in the management of intraarticular calcaneus fracture. METHODS: Twenty-four patients who suffered from intraarticular calcaneus fractures between 2014 and 2019 were included. Twelve of them had Sanders II fractures (group A) and 12 had Sanders III + IV fractures (group B). The mean follow-up duration was 37.5 months. The mean age at presentation was 54.23 ± 12.48 years. The skin condition at presentation was poor (blood-filled blisters) in 25% of patients equally distributed between the two groups. The mean time to surgery was 5.6 days where patients with poor skin conditions were treated lately. The technique involved percutaneous ascending proximal-to-distal pinning of the calcaneus after reduction using a 2 cm mini-incision below the lateral malleolus and augmenting the fixation with femoral head cancellous allograft. The primary outcomes variables analyzed in this study are post-operative Bohler angle, post-operative Gissane angle, American Orthopedic Foot and Ankle Society (AOFAS) ankle/hindfoot score at long-term follow-up (Excellent>95, Good 75-94, Fair 51-74, poor 0-50), and the delta angle benefit score. The secondary outcomes included post-operative complications such as infection and osteoarthritis. RESULTS: The radiological results showed significant improvement of Bohler angle from 6.09° ± 21.6 pre-operatively, to 31.79° ± 14.1 postoperatively with a p-value <0.001. An adequate reduction was achieved in 54.16% to 70.8% of patients. There is a trend to normalization of overcorrected fracture especially Sanders II with a mean reduction of 12,71° ± 11,88 at one year post-operatively (p=0.05). AOFAS score at the last follow-up shows 20.83% poor results (AOFAS<50), 50% fair results (AOFAS between 51-74), 16.67% good results (AOFAS 75-94), and 12.5% excellent results (AOFAS>95. The satisfaction rate was 83.3% (45.8% partially satisfied, and 37.5% fully satisfied). The incidence of superficial infection (wound inflammation and pin tract infection) was more prevalent in higher group B (40%) compared to group A (0%) with p=0.014. Other complications including osteoarthritis and varus deformity were found in 95.8% and 58.3% of patients respectively at three-year follow-up. CONCLUSION: The combination of minimally invasive osteosynthesis and femoral head allograft for the treatment of intraarticular calcaneus fractures seems to give fair to good functional results. Radiological data demonstrated that when the Bohler angle is over-reduced >40°, there was a tendency to autocorrection over time. This may be due to progressive depression of the angle over time as weight bearing is authorized; however, this must be analyzed carefully due to the low number of patients who were overreduced (seven patients). Our study demonstrates that this technique has a low early complication rate (especially low infection and soft tissue problems) but carries high long-term complications such as osteoarthritis and hindfoot varus.

An Uncommon Finding of Posterior Cruciate Ligament Intrasubstance Cyst: A Case Report and Review of Literature.

Introduction: Ganglion cyst of the cruciate ligaments is a rare entity. These cysts are usually found as incidental finding during knee arthroscopy, even though they can be the cause of knee discomfort or dull pain without a clear etiology. Case Presentation: We present herein a case of 35-year-old male who presented with unexplained dull knee pain. Magnetic resonance imaging (MRI) was performed and it showed a cystic-like lesion measuring 14 mm localized within the fibers of the posterior cruciate ligament (PCL) with no other significant pathology identified. A diagnosis of symptomatic PCL intrasubstance cyst was made. Patients were treated by arthroscopic debridement with good long-term outcomes. Conclusion: Ganglion cysts of the PCL are uncommon and especially if they were localized within the PCL fibers. MRI studies are inevitable to make the diagnosis, and arthroscopic debridement remains a reasonable surgical option with low recurrence rate.

Management of Chronic Transtibial Articulocutaneous Fistula After All-Inside ACL Reconstruction: A Case Report.

CASE: A 29-year-old man presented 2 years after anterior cruciate ligament (ACL) reconstruction by autologous semitendinosus graft and suspensory fixation on both tibial and femoral sides for chronic drainage of clear fluid from an anteromedial wound at the site of the tibial tunnel with a visible sinus tract. Magnetic resonance imaging showed a transtibial articulocutaneous fistula. The patient was treated by tunnel debridement, impaction bone grafting, bioresorbable interference screw, and cement to fully seal the tunnel. The surgery was successful with good clinical outcomes for recurrence and knee stability. CONCLUSION: Communicating transtibial articulocutaneous fistulas are rare complications after ACL reconstruction. Tunnel debridement and filling with graft material affected by an interference screw seem to be an effective method for dealing with such a clinical scenario.

Reconstruction of Tibial Plateau Fracture Malunion in the Setting of a Large Cartilage Defect in an Adolescent: A Case Report.

CASE: An 18-year-old adolescent boy presented with knee pain and stiffness secondary to tibial plateau valgus malunion and osteochondral defect, 8 months after initial injury/fixation. We opted for a novel technique that reconstructs the convex lateral tibial plateau by using osteotomy and an osteochondral autograft harvested from the lateral aspect of the ipsilateral femoral condyle. CONCLUSION: The reported novel reconstruction technique is inexpensive, achievable with routine techniques, and demonstrated a favorable short-term outcome. At 3 years of follow-up, the patient had excellent, asymptomatic, left knee mobility and function with radiographic evidence of mild posttraumatic arthritis despite normal knee alignment.
