This study examined the differences in gait mechanics, isokinetic knee strength, and flexibility between a group of adults with symptomatic osteoarthritis (OA) of the knee (n = 15) and an age-, mass-, and gender-matched group of control subjects (n = 15). Both groups performed under similar environmental conditions. Our results suggest that patients with symptomatic OA of the knee have poorer flexibility in both the affected and unaffected legs and demonstrate significantly less (p less than .05) knee angular velocity and, to a lesser extent, knee range of motion during gait. They have an increased loading rate in the unaffected leg after heel strike, exert less peak vertical force during pushoff, and are significantly weaker in both the dominant and nondominant legs compared to adults with no lower extremity disease.

This systematic review and meta-analysis aimed to evaluate the effectiveness of psychological interventions compared to standard rehabilitation in patients with knee osteoarthritis (OA). Given the recognized influence of psychological factors in OA management, the review assessed their impact on pain, functional disability, and self-efficacy. A comprehensive search was performed across multiple databases, including PubMed, PsycINFO, CINAHL, the Cochrane Central Register of Controlled Trials, Web of Science, OpenGrey, and ClinicalTrials.

Purpose: Knee osteoarthritis (KOA) is a prevalent degenerative bone and joint disease observed in clinical practice. While acupuncture has demonstrated efficacy in treating KOA, the central mechanisms underlying its effects remain ambiguous. Recently, functional magnetic resonance imaging (fMRI) has been extensively applied in studying the brain mechanisms of acupuncture analgesia.

Background: Cartilage defects in the knee joint are areas of damage and wear to the cartilage that normally covers and protects the ends of bones. These defects occur due to sudden injuries, such as trauma or sports accidents, or due to chronic conditions, such as osteoarthritis. Cartilage acts as a shock absorber (cushion absorber), reducing the impact of mechanical stress on the joints, which helps prevent bone damage during movement.

Objective: With the global aging population, the incidence of OA is rising annually, and the number of TKA surgeries is rapidly increasing, placing a heavy economic and healthcare burden on society. As one of the key medications in the ERAS protocol, DXM can significantly reduce postoperative pain, suppress nausea and vomiting, and accelerate patient recovery. However, the safety of perioperative DXM use in patients with diabetes remains unclear.

Repetitive mechanical stresses on the knee joint during daily activities accumulate fatigue damage in the articular cartilage (AC), leading to wear and knee osteoarthritis (KOA). Effective treatments remain limited, underscoring the need for predictive approaches to identify KOA early. This study proposes a mathematical model to estimate AC degradation under cyclic loading from walking.
