Effects of fluoroscopy-guided conventional radiofrequency ablation in dissatisfed patients after total knee arthroplasty

Safety and Efficacy of Genicular Nerve Radiofrequency Ablation for Management of Painful Total Knee Replacement: A Systematic Review

“…One of the studies found after searching the references of included articles was subsequently excluded as it described non-genicular nerve supply and used pulsed GNRFA [26]. Finally, a total of nine studies qualified for further analysis, including one randomized, double-blind study, four case series, and four case reports [9,[27][28][29][30][31][32][33][34]. We could not obtain the full text of a poster presented at the European Society of Regional Anaesthesia meeting but subsequently included it in the analysis as it contained all required information in the abstract with a substantial number of patients [27] (Figure 1).…”

“…The eligible papers were scored according to the National Heart Lung and Blood Institute criteria in quality assessment [35]. One randomized controlled study scored 9 over 14 points, and three case series scored 7 over 9 points [9,[28][29][30]. The rest of the studies were single case reports (Tables 2, 3).…”

“…Clinical relevance is presented in Table 4 [36]. Six studies scored 5/5, one study scored 3/5, one study scored 4, and one study scored 2 [9,[27][28][29][30][31][32][33][34]. Q1: Was the study described as randomized, a randomized trial, a randomized clinical trial, or a randomized controlled trial?…”

“…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 ]. The overall improvement was approximately 27.86 points in the WOMAC score.…”

“…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].…”
