AbstractThe effect of intra-articular bupivacaine on postoperative pain following arthroscopy has been intensively studied for the knee joint but no data are currently available for the hip joint. The aim of the present prospective, randomized and double-blind study was to evaluate a possible effect of intra-articular bupivacaine on postoperative pain intensity following hip arthroscopy. A total of 26 patients were included: 13 received 20 ml of 0.25% bupivacaine through the trocar at the end of surgery and 13 patients received 20 ml of 0.9% NaCl as placebo. Postoperative pain intensity was assessed using a visual analogue scale (VAS) at 0.5 h, 4 h, 8 h, 12 h, 16 h and 20 h, at rest and during movement of the joint and on the basis of additional piritramide requirements. Furthermore, a mean VAS was calculated as the arithmetic mean of all VAS scores assessed over the whole study period. In the bupivacaine group, a significantly lower mean VAS was recorded at rest (17.5 vs 27.5, p=0.05) and during movement of the hip joint (23 vs. 46, p=0.001). The additional piritramide consumption tended to be higher in the placebo group. In conclusion, intra-articular bupivacaine following arthroscopic hip surgery reduces pain in the postoperative period mainly during movement and thus may possibly allow earlier mobilization.
