Medial collateral ligament avulsion from both tibial and femoral attachments: a case report

The medial collateral ligament (MCL) is the most commonly injured ligament of the knee joint. Proximal MCL tears occur more frequently than do distal ones. We report a 28-year-old man with a valgus injury of his left knee joint after a fall from a motorcycle. Magnetic resonance imaging of the affected knee joint revealed complete avulsion of the superficial MCL from both its femoral and tibial insertions. The meniscofemoral portion of the deep part of the MCL was also torn and the medial meniscus was subluxated. Such a pattern, an MCL tear with subluxation of the medial meniscus, is rare.

Influence of Intraoperative Medial Collateral Ligament Bony Avulsion Injury on the Outcome of Primary Total Knee Arthroplasty

BackgroundThe purpose of this study is (1) to find the clinical and radiological outcome of intraoperative bony avulsion of medial collateral ligament (MCL) treated with screw and washer construct and (2) to predict the preoperative factors which may contribute to the avulsion-type MCL injury during primary total knee arthroplasty (TKA).MethodsIntraoperative MCL avulsion injury occurred in 46 (0.8%) of the 4916 consecutive primary TKA from January 2011 to December 2015. After exclusion, the 41 knees were matched 1:2 with controls without MCL injury and compared for the various clinical, radiological, and functional parameters. The clinical parameters analyzed were age, gender, body mass index, preoperative diagnosis like osteoarthritis or rheumatoid arthritis, range of motion, sagittal deformity, and vitamin D levels. The radiological parameters calculated were coronal deformity, proximal tibial varus angle, distal femur valgus angle, joint line congruence angle, posterior tibial slope, “cup and saucer” morphology, presence or absence of knee subluxation, tibia vara, and femoral bowing. The preoperative and postoperative Knee Society Score and Knee Society Functional Score were analyzed. Complications or revisions, if any, were noted during the follow-up. Multivariate logistic regression analysis was used to predict the preoperative risk factors for MCL avulsion injury.ResultsAt a mean follow-up of 58.4 ± 19.3 months, there were no radiological or physical examination findings of instability. Compared to the preoperative disability, there was a statistically significant improvement in clinical scores (Knee Society Score and Knee Society Functional Score) in the final follow-up (P < .001) in both cases and the control group. The mean preoperative coronal deformity was 170.6 ± 6.96 in the study group and 167.7 ± 4.3 in the control group (P = .021). The mean preoperative tibial slope was 10.5 ± 4.9 in the study group and 7.91 ± 4.15 in the control group (P = .003). The preoperative knee subluxation was present in 48.8% knees (P < .001) and “cup and saucer” morphology in 68.3 knees (P < .001) in the study group. The adjusted odds of MCL avulsion injury were greater for severe varus deformity (odds ratio [OR] 1.462, 95% confidence interval [CI] 1.15-1.86), knee subluxation (OR 39.78, 95% CI 3.78-418.86), and “cup and saucer” morphology (OR 33.11, 95% CI 5.69-192.66).ConclusionIntraoperative MCL bony avulsion injury can be managed successfully with screw and washer construct without the need for increased prosthetic constraint in primary TKA. The presence of severe varus deformity, knee subluxation, and “cup and saucer” morphology tend to have an increased chance of MCL avulsion injury.     

锚钉缝合术修复治疗副韧带前束撕脱的疗效

目的评价锚钉缝合术对于全膝关节置换术(TKA)术中膝关节内侧副韧带(MCL)前束撕脱屈膝位不稳的临床效果。 方法回顾性分析了2011年1月至2017年12月在东莞市中西医结合医院骨科接受TKA的患者3 922例,确定术中MCL前束撕脱屈膝位不稳的病例48例(1.2%),所有患者接受锚钉缝合术。所有患者在术后6周内使用铰链式护膝,术后每次随访时,测量膝关节的运动范围。在术后6周、3个月、1年,及之后每年接受1次X线检查,以评估美国特种外科医院(HSS)膝关节评分,并以t检验行统计学分析。 结果在3 922例全膝关节置换术中,48例(1.2%)发生术中MCL损伤。其中,1例患者术后两年内死亡,2例患者失访,共有45例患者纳入了本研究。其中24例MCL中段撕裂,21例MCL附着点断裂。35例发生在十字韧带保留的TKA术中和10例发生在后稳定型TKA术中。患者末次随访时最大屈膝(111.2±18.8)°、最大伸膝(1.5±1.5)°以及活动范围(110.2±30.2)°明显高于治疗前(107.5±22.5)°、(5.5±4.5)°、(102.2±27.8)°(t ＝ 2.822、5.026、3.670,均为P<0.05)。平均随访时间(99.2±5.7)个月,没有1例患者发生膝关节不稳定。其中5例患者因为膝关节僵硬而接受了干预(4例手法推拿和1例翻修术),2例患者因为人工膝关节无菌性松动接受了翻修术。 结论TKA术中MCL前束撕脱可以通过锚钉缝合术修复治疗,然后进行铰链式护膝支撑。膝关节僵硬是一种常见的并发症。     

Factors for the presence of anteromedial rotatory instability of the knee

Anteromedial rotatory instability (AMRI) of the knee joint was investigated with an instrument newly designed to simulate the manual AMRI test and to quantify its magnitude. Thirty healthy subjects, 20 patients with anterior cruciate ligament (ACL) injury, and 10 with both ACL and medial collateral ligament (MCL) injuries were examined. Using the instrument, 100N of anterior force was applied to the proximal part of the tibia with the foot in neutral rotation, 30° of internal rotation, and 30° of external rotation, and the magnitude of anterior displacement was recorded. The measurement was carried out at 20° and 90° of flexion. A significant increase in anterior laxity was observed in all three rotation positions in the injured patients. However, the magnitude of laxity in external rotation was less than that in neutral rotation in the ACL injured patients, whereas it was the greatest in external rotation in ACL + MCL injured patients. Thus, we conclude that an injury involving both the ACL and MCL causes AMRI.     

Pure Varus Injury to the Knee Joint

A 30-year-old male was involved in a car accident. Radiographs revealed a depressed marginal fracture of the medial tibial plateau and an avulsion fracture of the fibular head. Magnetic resonance imaging showed avulsion fracture of Gerdy''s tubercle, injury to the posterior cruciate ligament (PCL), posterior horn of the medial meniscus, and the attachments of the lateral collateral ligament and the biceps femoris tendon. The depressed fracture of the medial tibial plateau was elevated and stabilized using a cannulated screw and washer. The injured lateral and posterolateral corner (PLC) structures were repaired and augmented by PLC reconstruction. However, the avulsion fracture of Gerdy''s tubercle was not fixed because it was minimally displaced and the torn PCL was also not repaired or reconstructed. We present a unique case of pure varus injury to the knee joint. This case contributes to our understanding of the mechanism of knee injury and provides insight regarding appropriate treatment plans for this type of injury.

Unstable Simple Elbow Dislocation Treated with the Repair of Lateral Collateral Ligament Complex

Background

Unstable simple elbow dislocation (USED) repair is challenged by the maintenance of joint reduction; hence, primary repair or reconstruction of disrupted ligaments is required to maintain the congruency and allow early motion of the elbow. We evaluated the effectiveness and the outcome of lateral collateral ligament (LCL) complex repair with additional medial collateral ligament (MCL) repair in cases of USED.

Methods

We retrospectively reviewed 21 cases of diagnosed USED without fractures around the elbow that were treated with primary ligament repair. In all cases, anatomical repair of LCL complex with or without common extensor origin was performed using suture anchor and the bone tunnel method. Next, the instability and congruency of elbow for a full range of motion were evaluated under the image intensifier. MCL was repaired only if unstable or incongruent elbow was observed. Clinical outcomes were evaluated using the Mayo elbow performance score (MEPS) and radiographic outcomes on last follow-up images.

Results

All cases achieved a stable elbow on radiographic and clinical results. LCL complex repair alone was sufficient to obtain the stable elbow in 17 of 21 cases. Four cases required additional MCL repair after restoration of the LCL complex. The overall mean MEPS was 91 (range, 70 to 100): excellent in 12 cases, good in 7 cases, and fair in 2 cases. All 17 cases with LCL complex repair only and 2 of 4 cases with additional MCL repair had excellent or good results by MEPS.

Conclusions

USED requires surgical treatment to achieve a congruent and stable joint. If the repair of lateral stabilizer such as LCL complex acquires enough joint stability to maintain a full range of motion, it may not be necessary to repair the medial stabilizer in all cases of USED.

An unusual rotational injury: pantibial ligamentous injury

Pantibial ligamentous injury including knee dislocation and tibiotalar joint subluxation is an uncommon severe rotational injury. A 21-year-old male injured his right knee falling from a motorcycle. Physical examination revealed effusion on the right knee and ankle, and posterior translation of the tibia as well. The MRI of the right knee and ankle demonstrated the following findings: a complete disruption of cruciate ligaments, the medial collateral ligament, posteromedial corner injury together with a peripheric tear in the medial meniscus, the ruptured deltoid ligament, ankle syndesmosis space widening (>5 mm) and lateral subluxation of talus. Deltoid ligament of the right ankle was repaired and ankle syndesmosis was fixed with a cortical screw. The PCL and ACL were reconstructed arthroscopically with autogeneous bone-patellar tendon-bone graft. The midsubstance tear of MCL, posteromedial corner and medial meniscus tear were primarily repaired with nonabsorbable sutures. 3 years after the surgery, the patient was called for the final examination. MRI and X-ray findings of the knee and ankle joint demonstrated the continuity of ACL, PCL, MCL, and deltoid ligament. The patient, who is a farmer, can go back to his job and perform his daily activities. We presented a previously unreported case that involves both simultaneous occurrence of knee dislocation and tibiotalar joint subluxation. We used the term “Pantibial ligamentous injury” for this case.
