“…Different functional scores, including Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Knee Injury and Osteoarthritis Outcome Score (KOOS), Oxford Knee Score, Short Form 36 (SF-36), were used in these studies, making it difficult to compare the outcomes. Overall, 42/70 (60%) of patients reported WOMAC scores as patient-reported outcome measures (PROM)[27,30]. Yoshimura et al reported an improvement of 23.2 points in WOMAC after the procedure, whereas Gönüllü et al reported an improvement of 30.2 points in the WOMAC functional score[27,30].…”
