Multicenter Study Comparative StudyLow back pain and other musculoskeletal pain comorbidities in individuals with symptomatic osteoarthritis of the knee: data from the osteoarthritis initiative.
To examine the association of concurrent low back pain (LBP), and other musculoskeletal pain comorbidity, with knee pain severity in symptomatic knee osteoarthritis (OA). ⋯ LBP, foot pain, and elbow pain are significantly associated with WOMAC knee pain score, as are a higher total number of pain locations. This may have implications for clinical trial planning.

Comparative StudyDevelopment and validation of the brief-satisfaction with appearance scale for systemic sclerosis.
Body image concerns are understudied in systemic sclerosis (SSc; scleroderma). The objective was to develop and cross-validate a brief version of the Satisfaction with Appearance Scale (SWAP) in order to reduce item redundancy, increase SSc relevancy, and improve the feasibility of body image assessment in SSc. ⋯ The Brief-SWAP is a reliable and valid measure of body image dissatisfaction and social discomfort in SSc that is shorter and more feasibly implemented than the SWAP.

Comparative StudyQuadriceps muscle weakness after anterior cruciate ligament reconstruction: a risk factor for knee osteoarthritis?
To identify risk factors for knee osteoarthritis (OA) 10-15 years after anterior cruciate ligament (ACL) reconstruction. We hypothesized that quadriceps muscle weakness after ACL reconstruction would be a risk factor for radiographic and symptomatic radiographic knee OA 10-15 years later. ⋯ This study detected no association between quadriceps weakness after ACL reconstruction and knee OA as measured 10-15 years later.
