Routine patella replacement with total knee arthroplasty has not been universally adopted because of associated patellofemoral complications such as anterior knee pain (AKP). In the proposed technique, the articular surface of the lateral facet of the patella is excised to the depth of the subchondral bone, and the medial facet is then cut parallel to the anterior surface. We evaluated any correlation between various radiographic parameters and AKP in 100 consecutive fixed-bearing posterior-stabilized total knee arthroplasties. There were no cases of fracture, avascular necrosis, subluxation, dislocation, patellar baja, or overstuffing of the patella. Anterior knee pain was present in 11% of cases, and no cases were severe or disabling. There were no correlations between AKP, range of motion, patellar size and shape, and any of the radiographic parameters.

Background: Previous clinical studies suggest that preserving the anterior cruciate ligament (ACL) is crucial for stable knee motion and long-term longevity of the reconstructed knee. The ACL damage or loss often occurs in advanced medial osteoarthritis (OA). This study aimed to investigate the correlation between ACL damage and varus deformity progression as a risk factor for ACL tears in knee OA.

Introduction: Anterior cruciate ligament (ACL) reconstruction (ACLR) is the gold standard for treating ACL injuries, particularly in soccer players who are at a high risk of knee injury. While professional athletes often return to sport (RTS) within 7-10 months after ACLR, non-elite players experience significant delays. There is a need to investigate neuromuscular deficits and functional asymmetries in the non-elite group, which may persist even after clearance for RTS.

Knee bracing is commonly used for rehabilitation after ligament surgery. However, the effectiveness of knee bracing in preventing ligament injuries is not widely studied. This study aimed to develop a computational methodology to investigate the effectiveness of a novel type of cable-stabilized knee brace on anterior cruciate ligament (ACL) strain during single-leg jump landing.

Background: Residual interlimb deficits after anterior cruciate ligament reconstruction (ACLR) can lead to functional maladaptation and increase the risk of reinjury. The tuck jump assessment (TJA) may offer a more effective evaluation of ACLR status as compared with traditional tasks owing to increased risk of altered landing mechanics, asymmetrical landing, and increased knee valgus attributed to the cyclical nature of the task. However, it remains unclear whether altered TJA kinetics resolve over time or persist through return-to-play phases of rehabilitation.

Background: Restoring pre-injury normal gait following Anterior Cruciate Ligament Reconstruction (ACLR) is a critical challenge. The purpose of this study was to compare spatiotemporal parameters in athletes following ACL reconstruction with healthy athletes when cognitive load and speed were manipulated.
Methods: Twenty male soccer players with an ACLR history and 20 healthy matched individuals completed walking tasks under four conditions: with and without a cognitive load (auditory Stroop task), and at preferred speed as well as high speed (20% higher than the individual's preferred speed).
