Abstract:

BACKGROUND: “Cocktail wine” therapy is a new way for pain relief after total knee arthroplasty with fewer side effects.
OBJECTIVE: To observe the early efficacy of postoperative periarticular injection of multimodal analgesia(“cocktail wine” treatment) after total knee arthroplasty.
METHODS: Twenty-six patients undergoing unilateral total knee arthroplasty had the same treatment of pain relief perioperatively. All the cases were injected with the “cocktail wine” intraoperatively. The postoperative visual analogue scale (VAS) of pain, the range of motion of knee joint and wound complications were analyzed versus the preoperative data.
RESULTS AND CONCLUSION: All the patients did not take the medicine of parenteral opiods, and there were significant improvement in pain VAS during rest and exercise for 1-3 days postoperatively. Time for active straight leg lifting was 2.5 days postoperatively in average. During the 2nd and 3rd days postoperatively, the average knee joint activities were 45° and 55°, and no wound complications occurred. These demonstrated that the periarticular injection of analgesia can reduce the scores of the VAS during rest and exercise and improve the activity of knee joints in the early stage, and it is simple, practical, safe and effective.
