AI InsightIn addition, VAS scores at all follow-up times were significantly higher in the control groupcompared with the other groups (p<0.001).Conclusion: Evidence from this study revealed that the combined injection of bupivacaine is more effective than its periarticular injection alone and provides effective post-operative pain management after TKA.

Objective: The aim of this study was to compare the efficacy of combined periarticular and incisional injections versus periarticular injection alone of bupivacaine in reducing post-operative pain after total knee arthroplasty (TKA).Methods: In this prospective, randomized, double-blind comparative study, 90 patients with primary osteoarthritis who underwent TKA were enrolled. The patients were then randomly divided into 3 groups (30 in each): group 1, without injection;group 2, with periarticular injection of 20 mL 0.5% bupivacaine hydrogen chloride (HCl) (100 mg) after implantation; andgroup 3, periarticular injection of 20 mL 0.5% bupivacaine HCl (100 mg) after implantation and incisional injection of 10mL 0.5% bupivacaine HCl (50 mg) before wound closure. Post-operative pain levels were measured using a 100-mm visualanalogue scale (VAS) (0 mm: no pain and 100 mm: worst pain) at 30 min and 1, 2, 4, and 6 h, post-operatively.Results: The mean VAS score in group 3 (the combined group-periarticular and incisional injections) within the first 4 hwas lower than that in group 1 and group 2 (p 0.001). However, the values were significantly lower than those of the controlgroup (63.56±9.73) (p<0.001). In addition, VAS scores at all follow-up times were significantly higher in the control groupcompared with the other groups (p<0.001).Conclusion: Evidence from this study revealed that the combined injection of bupivacaine is more effective than its periarticular injection alone and provides effective post-operative pain management after TKA.
