Abstract
BACKGROUND AND AIMS: To evaluate the effect of intra-articular ropivacaine injection on postoperative knee painafter day case arthroscopy. MATERIAL AND METHODS: We studied one hundred outpatients in a prospective, randomized, double-blind fashion to examine the postoperative analgesic effect of intra-articular ropivacaine or saline injected into the knee joint after day-case knee arthroscopy performed under spinal anaesthesia. Patients were interviewed postoperatively with a standardized questionnaire. The postoperative pain was measured using a 100-mm visual analogue scale (VAS). RESULTS: There were no statistically significant differences in the VAS scores of knee pain eight hours or more after the operation between the intra-articular ropivacaine and saline groups, and there was no significant difference in the need for postoperative pain killer. CONCLUSIONS: This study failed to demonstrate a decrease in postoperative VAS scores at eight hours and later postoperatively when 20 ml of ropivacaine 0.5% were injected intra-articularly after day-case knee arthroscopy performed under spinal anaesthesia. Furthermore, there was no significant difference in the need for postoperative pain medication between the study groups.
