Six randomized controlled trials, with a total of 776 knees, were included in this meta-analysis to assess the effects of circumpatellar electrocautery on patient outcomes following total knee replacement. Pain, the Oxford Knee Score, range of motion, and complications were among the outcomes assessed. Pooled analyses demonstrated no difference in anterior knee pain or incidence of complications between groups treated and not treated with circumpatellar electrocautery, although functional outcomes (including WOMAC, Patellar scores, and postoperative range of motion) were significantly benefited in those who received circumpatellar electrocautery.
