We followed up 92 patients with total knee replacement and a pre-operative knee flexion of at least 90 degrees . The patients were followed up regularly at 3 months, 6 months and 1 year. The outcome measured was the amount of maximum passive knee flexion at the end of 1 year after replacement. The potential factors affecting the final flexion range were investigated. After regression analysis, apart from pre-operative knee flexion (p<0.001), the most significant independent surgical factors that predict the amount of post-operative flexion were presence of residual posterior femoral condyle osteophyte (p=0.046) and overstuffing the patella by more than 2 mm during resurfacing of the patella (p<0.001).

Joint degeneration characterized by cartilage deterioration and bone wear is the hallmark of osteoarthritis (OA), a condition that worsens over time. Total knee arthroplasty (TKA) is the most common effective treatment for OA. Conventional therapy training (CTT) is the standard intervention; we are testing whether intensive therapy training (ITT) provides different results when used preoperatively.

Background: Failure of primary cartilage restoration procedures of the knee that proceed to necessitating revision cartilage procedures represent a challenging clinical scenario with variable outcomes reported in previous literature.
Purpose: To perform a systematic review and meta-analysis of clinical outcomes and adverse events after revision cartilage restoration procedures of the knee for failed primary cartilage procedures.

The effect of different textured foot orthoses on ankle and knee joint muscles co-contraction in male and female older adults during walking.

Faculty of Physical Education and Physiotherapy, Federal University of Uberlandia, Uberlandia, MG, Brazil.
Background: Foot orthoses have been considered to affect static and dynamic functional capacity and could help older adults maintain balance while walking. However, the impact of textured foot orthoses over co-contraction strategies remains uncertain. Therefore, this study aimed to assess the effect of different textured foot orthoses on ankle and knee joint muscle co-contraction in male and female older adults during walking.

Purpose: Medial meniscus ramp lesions (MMRLs), lateral meniscus posterior root tears (LMPRTs), and anterolateral complex injuries (ALCIs) are major secondary stabiliser injuries associated with anterior cruciate ligament (ACL) injuries. This study aimed to investigate the effect of the number of secondary stabiliser injuries on knee instability in ACL injuries.
Methods: Patients who underwent primary ACL reconstruction between January 2017 and May 2023 were enroled in this study.

Purpose: To quantify the effect of increasing the posterior tibial slope (PTS) on knee kinematics and the resultant medial and lateral meniscal forces.
Methods: In this controlled laboratory study, a 6 degrees of freedom (DOF) robotic testing system was used to apply external loading conditions to seven fresh-frozen human cadaveric knees: (1) 200-N axial compressive load, (2) 5-N m internal tibial +10-N m valgus torque and (3) 5-N m external tibial + 10-N m varus torque. Knee kinematics and the resultant medial and lateral meniscal forces were acquired for two PTS states: (1) native PTS and (2) increased PTS.
