Knee Injury and Osteoarthritis Outcome Score

The Knee Injury and Osteoarthritis Outcome Score (KOOS) is a patient-reported outcome measure designed for active patients with knee injury and osteoarthritis. Developed by Roos and colleagues in 1998, KOOS extends assessment beyond traditional osteoarthritis scales to include symptoms, pain, function in daily living, function in sport and recreation, and knee-related quality of life—making it ideal for younger, more active populations.
