Summary: KA TKA was found to restore a more native amount and distribution of MCL strain compared to MA TKA. This suggests that KA TKA may lead to better performance and more normal knee sensations for patients.

Summary: The study found that MCL injury significantly affects postoperative function, range of motion, complications, and revision rates in patients undergoing TKA, with adverse outcomes being more common. Surgeons need to pay more attention to and prevent MCL injuries during TKA surgeries.

Summary: The study aimed to investigate the clinical and radiological outcomes of intraoperative bony avulsion of the medial collateral ligament (MCL) treated with a screw and washer construct during primary total knee arthroplasty (TKA), as well as to predict preoperative factors contributing to such injuries. Results showed that severe varus deformity, knee subluxation, and cup and saucer morphology were associated with an increased risk of MCL avulsion injury.

Summary: The study developed and validated a musculoskeletal model of cruciate-retaining total knee arthroplasty, investigating the effects of varus/valgus alignment adjustment and unbalanced medial/lateral ligament laxity during gait. Results indicated that 2 degrees of valgus alignment adjustment or varus alignment with balanced ligament models did not increase contact force or ligament tension.

Summary: The study compared the effects of bone modification and soft tissue releases in achieving balance in medial varus deformity of the knee. It was found that bone modification was more effective in reducing pressures and improving patient-reported outcomes.

Summary: The effects of bicruciate-retaining total knee arthroplasty (BCR-TKA) on the tensile force of collateral ligaments during cross-leg sitting and squatting were analyzed in this study. Knee joint kinematics were evaluated and the tensile force was calculated based on the distance between femoral and tibial attachment areas for different components of collateral ligaments. The results showed that BCR-TKA had no significant effect on the tensile force of superficial medial collateral ligament (sMCL), but affected the tensile force of deep medial collateral ligament (dMCL) and lateral collateral ligament (LCL).

Summary: In this study, the feasibility and clinical efficacy of a modified medial collateral ligament indentation technique in total knee arthroplasty (TKA) with severe type II valgus deformity were explored. The results showed that the modified technique achieved good outcomes in TKA with type II valgus deformity of >20 degrees, including maintaining a normal joint line level, reducing the use of constrained condylar knee prostheses, and having fewer complications.

Summary: This study found that the need for medial ligament balancing during surgery was determined by constitutional alignment and preoperative mechanical parameters. Patients with constitutional varus and a larger change in medio-lateral gap difference in extension had a higher incidence of requiring medial ligament balancing.

Summary: The study found that in vitro, a fixed-bearing CCK-TKA knee provided more rotational constraint than the native knee. Both soft tissues and the semi-constrained implant were involved in restricting rotational knee laxity.

Summary: Research suggests that medial epicondylar osteotomy is a safe technique during total knee arthroplasty for patients with severe varus deformity. Compared to extensive medial release, medial epicondylar osteotomy has similar effects in correcting angles and medial joint line gaps.

Summary: The study investigated the length change of sMCL and LCL during lunge and its association with KSS following MP-TKA. The length of certain ligament bundles showed correlations with KSS.

Summary: The study examined the association between compartment pressures during total knee arthroplasty (TKA) and patient-reported outcome measurements (PROMs). The results showed that higher medial compartment pressures were observed during TKA. However, although compartment pressures are an important factor, they are not the sole predictor of patient satisfaction.

Summary: The study aimed to assess the effects of posterior cruciate ligament resection on joint center gap, varus ligament balance, and rotational changes of the femur and tibia. The results showed that after posterior cruciate ligament resection, the joint center gap, varus ligament balance, and tibial internal rotation significantly increased.

Summary: When performing arthroscopy in patients with a tight tibiofemoral joint space, medial collateral release can reduce direct iatrogenic cartilage damage in the knee. It is recommended to perform medial collateral release in surgeries that access the posteromedial compartment, with two main techniques available.

Summary: This study investigated the imaging characteristics of incomplete intertrochanteric fractures and isolated greater trochanter fractures, revealing that incomplete fractures mainly occur in the anterior cortex of the intertrochanteric area, which is notably different from the extension pattern of isolated greater trochanter fractures on MR images.

Summary: This study compared the tilt angle of femoral stems with different lengths but similar designs. The results showed that the anterior tilt in the sagittal plane was prominent with the use of shorter stems, which resulted in a decreased range of motion in hip extension.
