Tóm tắt	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.	The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) is a widely used patient-reported outcome measure designed to assess pain, stiffness, and physical function in patients with osteoarthritis of the hip or knee. Developed by Bellamy and colleagues in 1988, it has become the gold standard outcome measure in osteoarthritis clinical trials and practice.
