30 years with the Knee injury and Osteoarthritis Outcome Score (KOOS)

This narrative review describes the development and use of patient-reported outcomes over 30 years, focusing on the Knee Injury and Osteoarthritis Outcome Score (KOOS). KOOS is a five-subscale patient-reported instrument intended for use from the time of knee injury to the development of OA. Numerous studies have confirmed that the psychometric properties of the KOOS and its short-form KOOS-12 are acceptable. More recent research has focused on the use and interpretation of KOOS scores in clinical trials using thresholds, such as minimal important difference, patient-acceptable symptom state, and treatment failure.
