Arthritis is a term that means inflammation of a joint There are many types of arthritis.One of them is Osteo arthritis. Osteoarthritis is also called 'degenerative joint disease,' or 'wear-and-tear arthritis.'. Quadricep is the muscle which straightens the leg at the knee joint. A stronger quadriceps muscle helps to prevent the deterioration of cartilage at the knee cap among those with knee osteoarthritis, according to research done at the American College of Rheumatology Annual Scientific Meeting in Washington, DC. Strengthening exercises have always been welcomed for the quadriceps muscle of the leg as it was very beneficial to the knee joint in those with knee osteoarthritis. Earlier it was thought that greater quadriceps strength may be harmful to the tibiofemoral joint. "Those with better quadriceps strength were less likely to lose cartilage behind the knee cap," explains Shreyasee Amin, MD, Assistant Professor of Medicine, Mayo Clinic, Rochester, Minnesota, and principal investigator of the study. "This makes sense as a stronger quadriceps would be better able to keep the knee cap from moving laterally and tracking abnormally with joint movement. This study should encourage patients with knee osteoarthritis to speak with their doctors about how best to improve quadriceps strength."
