Using the patient acceptable symptom state (pass) to evaluate KOOS outcomes 3-12 years following a youth sport-related knee injury

Abstract

Purpose: Anterior cruciate ligament (ACL) and other traumatic intra-articular knee injuries are associated with an increased likelihood of developing knee joint osteoarthritis (OA). Research has elucidated the negative consequences on health outcomes that are present in this population in the short-term (1-2 years) and medium-term (3-15 years) interval post injury. The Knee Injury and Osteoarthritis Outcome Score (KOOS) is a common patient-reported outcome measure (PROM) used to track the most prevalent clinical features across the timeline from knee injury to OA.
