Summary: This study found that medial laxity is associated with clinical outcomes in TKA, especially when medial laxity is >= 5 degrees. Lateral laxity, on the other hand, does not impact clinical outcomes. Total varus and valgus laxity >= 10 degrees at 30 degrees of knee flexion lead to poorer outcomes.

Summary: This study describes the correlation between knee joint anatomical features and passive range of motion using a statistical model. The results show a negative correlation between specific anatomical features and tibiofemoral laxity. This is important for the development of orthopedic implant designs and identifying specific implant articular geometry for achieving a targeted passive range of motion.

Summary: Ankle-foot orthoses (AFOs) are braces worn to support ankle motion, with rotational stiffness being a key mechanical property that affects gait biomechanics. The AFO Stiffness Measurement Apparatus (SMApp) was designed to measure torque and angle as an AFO moves through a range of motion, providing high reliability for all measured AFO properties. The SMApp can be used for AFO material fatigue testing, validating finite element models, and evaluating speed effects on AFO properties in future studies.

Summary: The study assessed the reliability of measuring weight-bearing ankle dorsiflexion range of motion with a smartphone application, showing moderate reliability and excellent concurrent validity. It is a suitable method for assessing ankle dorsiflexion mobility when weight-bearing is not contraindicated.

Summary: This scoping review aimed to identify digital, portable height/length measurement devices for children. Out of the twelve devices identified, only six met the ideal accuracy standard set by UNICEF, and one device met the minimum accuracy standard. The Leica DistoD2 device scored the highest, followed by Autoanthro and GLM30.

Summary: Canonical correlation analysis (CCA) is a multivariate approach increasingly used in neuroimaging studies to identify correlations between two sets of variables related to brain-behavior relationships. This study systematically assessed the stability of CCA and found that both the subject-to-variable ratio (SVR) and correlation strength greatly influence the stability of CCA. The results provide a practical guideline for interpreting CCA results and applying CCA in neuroimaging studies.

Summary: The purpose of this research was to develop a sensor-based system for measuring the results of strain sensors applied to the knee joint. The system was compared to the current static mechanical measurement system. The measurement focused on the internal rotation laxity of the knee joint, which is relevant to anterolateral knee laxity and ACL injury.

Summary: This study analyzes the equipment system resilience metric using reliability engineering parameters, proposes a hybrid resilience metric, verifies its correctness under special circumstances, provides a concrete representation of the measurement method, and gives the influence of reliability engineering parameters on the resilience metric. The failure rate is identified as a crucial parameter in both equipment design and improvement stages, with the importance of other parameters varying based on the specific system. The research offers quantitative indexes for the resilience process from fault to repair, supporting optimizations in equipment design and improvement.

Summary: IMUs are widely used in various fields, but there is a lack of research on their dynamic metrological performances and reliability under real environmental conditions. A new test plan based on sine sweep vibration profiles has been developed to simulate the real operating conditions of IMUs and analyze the effects of mechanical stress on microelectromechanical sensors.

Summary: This study evaluated clinical and radiographic outcomes after modified anatomic lateral ligament reconstruction for patients with severe ankle instability or failed previous stabilization. Patients undergoing revision procedures had significantly lower postoperative patient-reported outcome scores and talar tilt measurements compared to those undergoing primary procedures, but the pre- to postoperative change in talar tilt was not significantly different between the groups.
