Abstract

Purpose: To report the variability in outcome measures after meniscal surgery and to compare responsiveness between patient-reported outcome measures (PROMs). Methods: A systematic search of the PubMed/MEDLINE and Web of Science databases was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. A total of 257 studies met inclusion criteria. Patient and study attributes were extracted, including pre- and postoperative means for PROMs. Of the studies that met inclusion criteria for responsiveness analysis (2+ PROMs reported, 1-year minimum follow-up; n = 172), we compared the responsiveness between PROM instruments using effect size and relative efficiency (RE) if a PROM could be compared with another in at least 10 articles. Results: In total, 18,612 patients (18,690 menisci, mean age = 38.6 years, mean body mass index = 26.3) were included in this study. Radiographic measures were reported in 167 (65.0%) studies, range of motion was reported in 53 (20.6%) studies, and 35 different PROM instruments were identified. The mean number of PROMs in each article was 3.6 and 83.8% reported 2 or more PROMs. The most used PROMs were Lysholm (74.5%) and IKDC (51.0%). IKDC was found to be more responsive than other PROMs, which include Lysholm (RE = 1.03), Tegner (RE = 3.90), and Knee Injury and Osteoarthritis Outcome Score (KOOS) Activities of Daily Living (ADL) (RE = 1.12). KOOS Quality of Life (QoL) was also more responsive than other PROMs, such as IKDC (RE = 1.45) and KOOS ADL (RE = 1.48). Lysholm was more responsive compared with KOOS QoL (RE = 1.14), KOOS ADL (RE = 1.96), and Tegner (RE = 3.53). Conclusions: Our study found that IKDC, KOOS QoL, and Lysholm were the most responsive PROMs. However, because of the previously reported risks of either floor effects (KOOS QoL) or ceiling effects (Lysholm), the IKDC may offer a more complete psychometric profile when quantifying outcomes after meniscus procedures. Clinical Relevance: To improve clinical outcomes, surgical decision-making, and research methodology, it is important to determine which PROMs are the most responsive after meniscal surgery.
