Patient-Reported Outcome Measures in the Repair of Chondral Defects: How Well Do the Scores Relate to Each Other?

Introduction: In the repair of focal chondral defects, there are several patient-reported outcome measures (PROMs) that are used to assess the patient's well-being. However, the question remains as to how well one scoring system relates to another, which may restrict the comparison of results from different studies. Therefore, we examined the strength of correlations between the Lysholm and KOOS scores.
