Abstract:
BACKGROUND: Total knee arthroplasty is an important measure to save the function of knee joint, but the postoperative pain caused great pain to patients. On the background of multimodal analgesia, cocktail therapy and femoral nerve block are widely used in clinic, and the analgesic effect is exact; however, the analgesic effect and safety of the two methods used together are unknown, so more clinical evidence is needed. OBJECTIVE: To study the effect and safety of analgesic and functional recovery of cocktail therapy combined with femoral nerve block after total knee arthroplasty. METHODS: Totally 100 patients undergoing primary unilateral total knee arthroplasty were enrolled. One hundred patients were randomly divided into two groups (n=50 per group) according to the table of random numbers. Group A was given cocktail therapy combined with femoral nerve block; group B received the injection of same volume of normal saline surrounding the knee joint combined with femoral nerve block. The postoperative resting-state visual analogue scale score, knee joint range of motion, global pain scale, and incidences of adverse reactions were compared between groups. The time and frequency of analgesic drugs were recorded. RESULTS AND CONCLUSION: (1) The postoperative visual analogue scale score at rest in the group A was significantly lower than that in the group B at 24, 36 and 48 hours postoperatively (P < 0.05). The scores at 12 and 72 hours did not differ significantly between groups (P < 0.05). (2) The knee joint range of motion on postoperative 1 and 3 days in the group A was significantly higher than that in the group B (P < 0.05), and no significant difference was detected at 14 days, 1 and 3 months postoperatively (P < 0.05). (3) At 3 months after operation, there was no significant difference in the Global Pain Scale between the two groups (P < 0.05). (4) There was no significant difference in incidences of adverse reactions and additional analgesics between the two groups (P < 0.05). (5) In summary, cocktail therapy combined with femoral nerve block can relieve the early resting pain after total knee arthroplasty, and improve the activity of knee joint in the early stage, which is safe and effective.
