To determine if any factors are associated with knee stiffness after total knee arthroplasty (TKA), we retrospectively reviewed the medical records and radiographs of patients who had knee manipulation after total knee replacement at Scott & White Memorial Hospital from 1983 to 1993. Twenty-five patients who had knee manipulation after TKA were matched by surgeon, year of surgery, and age (+/- 5 years) with a study group of 25 patients who did not have knee manipulation after TKA. Patients in the manipulated group had decreased flexion at the time of discharge from the hospital after the knee arthroplasty and a decreased final flexion. The age of the patient, time from surgery to manipulation, and preoperative flexion did not correlate with final flexion attained in the manipulated group. Relative to the control study group, the manipulated group had an increase in postoperative anteroposterior femoral thickness. A decrease in patellar height was noted both in the manipulated group and in the control nonmanipulated group. There was no significant difference between groups for a change in patellar height.

Osteoarthritis (OA) is a degenerative joint disease accompanied with the loss of cartilage and consequent nociceptive symptoms. Normal articular cartilage maintains at aneural state. Neuron guidance factor Semaphorin 3A (Sema3A) is a membrane-associated secreted protein with chemorepulsive properties for axons.

Background: Postoperative knee arthrofibrosis after arthroscopic ligament reconstruction is a serious complication. Among adolescents, risk factors for postoperative arthrofibrosis are not well characterized and the effectiveness of early manipulation under anesthesia (MUA) is not well established.
Purposes: To identify risk factors for arthrofibrosis after arthroscopic knee ligament reconstruction in adolescent patients and to evaluate the safety and effectiveness of early MUA.
The Readability Study: A Randomised Trial of Health Information Written at Different Grade Reading Levels.

Background: Despite increasing attention on health literacy and the inclusion of grade reading level recommendations in guidelines, it remains unclear if lowering the grade reading level of written health information to specific target grades improves patient-related outcomes.
Objective: To assess whether grade reading level of written information affects knowledge, perceived reading ease, acceptability and trustworthiness of information and, to explore whether information written at a lower grade reading level reduces disparities in outcomes across health literacy levels.
Design: We conducted a 4-arm online randomized trial with a community sample of adults living in Australia from 31 July to 20 September 2023.

Purpose: Alpine skiing races are physically demanding events characterized by numerous repeated near-maximal activations of the lower limb muscles. Although this type of task is known to induce neuromuscular fatigue, electromyographic activity (EMG) adaptations after repeated maximal-intensity skiing have not been previously investigated.
Methods: Six skiers completed a 6-turns section with (FAT) and without performing 30 giant slalom (GS) turns (CONT).

Robotic joint surgery (RJS) has demonstrated high precision and reproducibility in total hip and knee arthroplasty,the integration of artificial intelligence(AI) has further enhanced the intelligence level of key processes,including surgical planning,registration,surgical manipulator control,and robot autonomy. AI-powered surgical planning improves implant positioning accuracy through deep learning,while AI-powered registration overcomes the limitations of traditional methods in precision and efficiency. Additionally,reinforcement learning and neural networks have optimized surgical manipulator control,improving operational accuracy and human-robot interaction.
