: To identify baseline characteristics that modified the effect of a 12-week quadriceps-focused (QE) vs hip muscle-focused (HE) exercise program on symptoms and physical function, through changes at baseline in the Anterior Knee Pain Scale (AKPS) in patients with PFP. A secondary analysis of a 26-week randomized trial involving 200 participants with patellofemoral pain. Participants were randomly assigned to a QE or HE program with a duration of 12 weeks. The primary outcome was change from baseline in the AKPS at week 12 and week 26. Subgroups were predefined and based on baseline information: presence of low back, hip, ankle, or bilateral knee pain; body mass index (BMI); sex; age; education; occupation; hypermobility; quadriceps strength; dynamic knee alignment; midfoot mobility; exercise self-efficacy; pain self-efficacy; pain catastrophizing; neuropathic pain; pain duration; and pain severity. Participants with pain catastrophizing seemed to benefit from HE with a subgroup difference in treatment effect of 8.3 AKPS points at week 12 (95%CI 1.6 to 15.0). At week 26, participants with a baseline BMI above 25 seemed to benefit from HE with a subgroup difference in treatment effect of 11.1 (95%CI 4.8 to 17.4), and participants with severe knee pain at baseline seemed to benefit from QE with a subgroup difference of -9.1 (95% CI: -15.7, -2.6). Hip-focused exercises may provide more benefits than quadriceps-focused exercises among patients with patellofemoral pain and pain catastrophizing or overweight. Quadriceps-focused exercises may provide more benefits than hip-focused exercises for patients with severe knee pain. .

Background: Bone mineral density (BMD) is an indicator of bone health that predicts future bone fractures. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) is used to assess the severity of symptoms related to pain, stiffness, and function in diseased hip and knee joints. Here we assessed whether BMD measured at specific sites predicts WOMAC scores in healthy individuals whilst controlling for sociodemographic variables.

Knee osteoarthritis contributes substantially to worldwide disability. Post-traumatic osteoarthritis (PTOA) develops secondary to joint injury, such as ligament rupture, and there is increasing evidence suggesting a key role for inflammation in the aetiology of PTOA and associated functional deficits. Colony stimulating factor 1 receptor (CSF1-R) has been implicated in the pathogenesis of musculoskeletal degeneration following anterior cruciate ligament (ACL) injury.

Introduction: Whether a popliteal plexus block improves postoperative pain following total knee arthroplasty remains debated. This randomized trial tested if adding a popliteal plexus block to a continuous femoral nerve block decreases postoperative opioid requirement.
Methods: We included 66 patients undergoing total knee arthroplasty.

Clinical Scenario: Individuals with patellofemoral pain (PFP) present with a variety of neuromuscular and psychological deficits, with the "gold-standard" for treatment being rehabilitation programs with strengthening-based exercises. While such interventions primarily target pain and function measures, it is unknown whether psychological measures such as fear-avoidance beliefs (FABs) are also affected.
Clinical Question: Is rehabilitation including strengthening exercises effective in improving FABs in individuals with PFP?
Summary Of Key Findings: Three studies met the inclusion criteria and were included in the appraisal.
