Background: In cases of acute combined posteromedial and anterior cruciate ligament (ACL) injuries, primary repair of the superficial medial collateral ligament (sMCL) and posterior oblique ligament (POL) with suture tape augmentation may be a reasonable alternative to standard tendon reconstruction techniques. Purpose/Hypothesis: The purpose was to examine the rotational and valgus laxity with ACL strain following sMCL and POL repair with suture tape augmentation at various degrees of knee flexion. It was hypothesized that this technique would restore knee laxity and kinematics comparable with those of the intact state. Study Design: Controlled laboratory study. Methods: Ten cadaveric knee specimens (mean ± SD, 57.9 ± 5.9 years) were obtained. Specimens were tested with the tibia fixed and the femur mobile on an X-Y table. Each specimen was tested in 4 conditions according to the state of the sMCL and POL: native, deficient, repaired with suture tape augmentation, and reconstructed with tendon allografts. Valgus laxity was tested with 40-N force applied in the lateral direction of the femur, and rotational motion was tested with 5-N torque applied to the tibia. ACL strain during valgus stress was also measured. Each condition was tested in 0°, 15°, 30°, 45°, and 60° of knee flexion. Results: Dissection of the sMCL and POL led to significantly increased valgus laxity in all flexion angles, with a significant increase in ACL strain at 30° ( P < .001) and 45° ( P < .001). Ligament repair with suture tape augmentation demonstrated similar valgus and rotational laxity as compared with intact specimens, with the exception of increased internal rotation at 30° ( P = .005). Ligament reconstruction resulted in significantly increased valgus opening at 45° ( P = .048) and significantly increased internal rotation at 30° ( P < .001) as compared with the native state. Direct comparison between surgical techniques showed no significant differences. Conclusion: At time zero, ligament repair of the posteromedial knee with suture tape augmentation restored close-to-native valgus and rotatory laxity, as well as native ACL strain for cases of complete sMCL and POL avulsion. Clinical Relevance: Ligament repair of the sMCL and POL with suture tape augmentation may be a reasonable alternative to tendon reconstruction techniques in cases of acute combined posteromedial and ACL injuries with valgus and rotatory instability.

Till date, there are no clear guidelines regarding the treatment of multiple ligament knee injuries. Ligament repair is advantageous as it preserves proprioception and does not involve grafting. Many studies have reported the use of open repair and reconstruction for multiple ligament knee injuries; however, reports on arthroscopic-combined single-stage anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) repairs are scarce. In this report, we describe a case of type III knee dislocation (ACL, PCL, and medial collateral ligament (MCL) injuries) in a 43-year-old man, caused by contact while playing futsal. On the sixth day after injury, arthroscopic ACL and PCL repairs were performed with open MCL repair. The proximal lesions in the three ligaments that were injured were sutured using no. 2 strong surgical sutures. The ACL was pulled out to the lateral condyle of the femur and fixed using a suspensory fixation device. The PCL was pulled out to the medial condyle of the femur, and the MCL was pulled towards the proximal end of the femur; both were fixed using suture anchors. Early mobilization was performed, and both, clinical and imaging outcomes, were good two years after surgery.

Purpose of study. To study stressed-deformed state of the healthy knee joint and after arthroplasty using endoprostheses with either preservation or substitution of the posterior cruciate ligament by the method of numerical mathematical modelling.Materials and methods.Peculiarities of stress distribution in bones were determined on three mathematical models - healthy knee joint and joint after arthroplasty using endoprostheses with either preservation or substitution of the posterior cruciate ligament at the set load (80 kg) in straightened leg and either 45° or 90° knee flexion.Results. In healthy knee joint with a straightened leg the stress in the tibia is 2.3 times higher than in the femur. With knee flexion the stress in bone tissue increases and this increase is more intensive in the femur. After arthroplasty using endoprosthesis with substitution of the posterior cruciate ligament the stress in the tibia and femur is higher at all flexion angles as compared to arthroplasty using endoprosthesis with posterior cruciate ligament preservationConclusion.The obtained data may be used for mathematical substantiation of the advantage of endoprosthesis with preservation of the posterior cruciate ligament and in complex with the data of national and international registers will enable to optimize the treatment tactics in patients to whom knee arthroplasty is indicated.
