Exercise and osteoarthritis: are we stopping too early? findings from the Clearwater Exercise Study.

The value of exercise for people with knee osteoarthritis (OA) receives continuing consideration. The optimal length of study follow-up time remains unclear. A group of individuals with knee OA participating in an exercise intervention was followed for 2 years.

Effect of regular exercise on the radiographic progression of foot osteoarthritis.

Among the elderly, osteoarthritis often causes chronic pain and disability. Although research has addressed the association between exercise and osteoarthritis, few studies have examined the effect of exercise on the radiographic progression of osteoarthritis. We investigated the relationship between ongoing exercise and radiographic progression of foot osteoarthritis.

The association of radiographic foot osteoarthritis and radiographic osteoarthritis at other sites.

Objective: To quantify the association between radiographic foot osteoarthritis (OA) and radiographic OA at four joints: second distal interphalangeal (DIP), third proximal interphalangeal (PIP), first carpometacarpal (CMC), and the knee.

Methods: Data collected for the Clearwater Osteoarthritis Study (COS) were analyzed (N=3436). The study outcome was first metatarso-phalangeal joint (first MTP) OA status.
