Strength training can relieve knee osteoarthritis

Osteoarthritis in the knee wears away the cushion of cartilage surrounding the joint and is a leading cause of disability, according to the American Academy of Orthaepedic Surgeons. While exercise and weight loss can help reduce pain and increase function, studies on the influence of quadriceps muscle strength on the knee have shown conflicting results, according to press information provided for a new study. The research team expanded the study parameters to include more areas of the knee joint than were covered in previous studies.
