Abstract
Objective: To evaluate the efficacy and safety of patellar denervation with electrocautery for reducing pain and improving clinical outcomes after total knee replacement. Methods: A comprehensive search was conducted across relevant databases, including PubMed, Scopus, EMBASE, Web of Science, and Cochrane Library databases on February 2020. Two researchers independently completed the literature screening, data extraction, and risk evaluation of bias. Outcome measures included visual analogue scale, opioid consumption, range of motion, patellar score, American Knee Society score, Oxford knee score and postoperative complications. STATA 13.0 software was applied for meta-analysis. Result: A total of nine studies involving 1319 patients were included in our study. The present meta-analysis indicated that patellar denervation with electrocautery was associated with improved pain relief and decreased opioid consumption after total knee replacement. There was significant difference between groups in terms of knee range of motion. Conclusion: Patellar denervation with electrocautery is effective in reducing pain and opioid consumption after total knee replacement. Postoperative range of motion is significantly better in patellar denervation group, which means that patellar denervation significantly improves clinical outcome.Keywords
