Summary: This study measured the strain patterns of normal and reconstructed anterior talofibular ligaments (ATFL) and calcaneofibular ligaments (CFL) using the miniaturization ligament performance probe system. The results showed that the strain patterns of reconstructed ATFLs and CFLs are not similar to those of normal ligaments.

Summary: This study evaluates the stability of Ligament Advance Reinforcement System (LARS) augmentation repair of ATFL compared to modified Brostrom repair and intact ATFL. Results show that LARS augmentation repair provides better stability. The use of LARS improves primary stability, reduces stress on the repaired ATFL, and facilitates ligament healing.

Summary: Anatomical descriptions of the posterior cruciate ligament (PCL) and meniscofemoral ligaments (MFLs) are abundant, with two bundles generally believed to form the PCL. However, a single bundle configuration with complex femoral insertion has been reported. This study confirmed the PCL as a single flat ribbon-like bundle, and revealed the masking effect of the anterior menisco-femoral ligament (AMFL) on the femoral insertion of the PCL. The femoral insertion of the PCL was found to be located further back relative to the distal joint cartilage.

Summary: By measuring the length and tension of ligaments at different angles of the elbow joint, we found that the tension of the anterior oblique ligament (AOL) increased with elbow extension, while the tension of the posterior oblique ligament increased with elbow flexion. The tension and stress of the anterior and posterior bands were balanced around 60 degrees.

Summary: Hip arthroscopic segmental and circumferential labral reconstruction have similar outcomes in short-term follow-up. The use of bigger circumferential reconstruction methods may eventually become outdated due to the lack of clear benefits compared to segmental techniques. Further research is needed to evaluate the variables involved in labral reconstruction and compare the effectiveness of different techniques.

Summary: Calcar-guided short-stem THA effectively restores femoral antetorsion, but the impact on long-term clinical outcomes and complications requires further exploration.

Summary: In this study, the strain and loading of ankle ligaments during different movements were evaluated using a new index. The findings provide objective data for progressively staging ligament loading during rehabilitation and can help prevent ankle sprains.

Summary: The assessment of hip strength is often overlooked in RTP assessment after ACLR. The study found that patients after ACLR had weaker hip abduction and adduction strength compared to the contralateral limb, with larger deficits in women. There was a correlation between hip and thigh strength ratios and patient-reported outcomes. Over time, hip strength improved in the ACLR limb.

Summary: The study demonstrated that proximal overresection compromises the distractive stability of the hip joint, but does not affect hip rotational stability.

Summary: This study validated a novel miniaturized ligament performance probe (MLPP) system for measuring the strain patterns of the anterior talofibular ligament (ATFL) during ankle motion. The results showed that the ATFL tensed near 20 degrees plantar flexion and the strain increased as the plantar flexion angle increased. Within the elastic range of the ATFL, the tensile force was proportional to the strain in all specimens, indicating the potential of the MLPP system in determining the relationship between limb position and ATFL ankle ligament strain patterns.

Summary: This study aimed to investigate the biomechanics of preventing excessive internal hip joint rotation. The results showed that the ischiofemoral ligament primarily restricted internal rotation of the hip joint, while the piriformis and obturator internus may also play a role in limiting internal rotation at specific angles.

Summary: This study investigates the thickness and intra-substance change of the anterior capsule of the hip joint, and compares the different capsular features in patients with different hip stability. The results show that patients with hip dysplasia have significantly reduced capsular thickness on MRI and delaminated anterior joint capsule, which may be a consequence of instability.

Summary: Implantable sensor OFS-TENG based on organogel/silicone fiber-helical structure has been developed for power-free and sutureable ligament strain monitoring. It shows high stability, ultrastretchability, and the ability to monitor knee ligament stretch and muscle stress in real-time, providing a solution for real-time diagnosis of muscle and ligament injuries.

Summary: This study used capacitive sensors to measure the strain of the median nerve within the carpal tunnel. The results showed that there was significantly higher strain on the median nerve within the carpal tunnel compared with at the proximal to the carpal tunnel during wrist extension. These findings can provide new information for understanding the pathogenesis of carpal tunnel syndrome.
