Abstract

It is important to monitor patient’s perception of the knee after anterior cruciate ligament (ACL) injury to evaluate their recovery/ rehabilitation at the short-, mid and long-term.

Patient reported outcome measures (PROMs) can be used for this purpose. For ACL specific PROMs it is important that they were validated in an ACL injured population. Furthermore, the following properties should be assessed: validity, reliability, responsiveness, floor and ceiling effects. Frequently used PROMs are International Knee Documentation Committee Subjective Knee Form (IKDC subjective), Knee Injury and Osteoarthritis Outcome Score (KOOS), Tegner activity score and Marx activity rating scale. Two knee-specific PROMs were modified and validated in children with knee injuries: KOOS-Child and IKDC Subjective Knee Evaluation Form in Children.
