The American Academy of Orthopaedic Surgeons (AAOS) released its recommendations in December 2008 for "best" practice guidelines. In looking at the commonly used treatments for osteoarthritis (OA), they underscored that many lack support from scientific evidence.
The AAOS guideline targets treatment for patients with OA of the knee whose disease has not progressed to the point of needing joint replacement surgery. It offers 22 treatment recommendations. The guideline is aimed at primary care physicians as well as orthopedic surgeons.
