RESUMEN
INTRODUCTION: Literature addressing postoperative pain management after hip arthroscopy is relatively scarce. This study aimed to assess if there was added analgesic benefit associated with postoperative intra-articular bupivacaine blockade for patients who received preoperative peri-acetabular blockade for hip arthroscopy procedures. METHODS: 52 patients were included in this comparative cohort study. Group 1 consisted of 20 patients who received preoperative peri-acetabular blockade and postoperative intra-articular blockade. The control group (Group 2), consisted of 32 patients who received only preoperative peri-acetabular blockade. Postoperative pain was recorded via visual analogue scale (VAS) pain scores, analgesic consumption, and pain diaries for 2 weeks postoperatively. RESULTS: Postoperative VAS pain scores were significantly lower in the experimental group at the 30-minute recovery room assessment (VAS scores Group 1: 1.1; Group 2: 3.00, p = 0.034). Other than the 30-minute recovery room assessment, VAS pain scores, narcotic medication consumption, and non-narcotic analgesic consumption did not differ between the 2 groups at any time point in the study period. CONCLUSIONS: This study did not demonstrate significant clinical benefit for patients who receive postoperative intra-articular blockade in addition to preoperative peri-acetabular blockade with bupivacaine 0.5%. We recommend the use of preoperative peri-acetabular bupivacaine blockade without intra-articular blockade postoperatively for pain control in the setting of hip arthroscopy surgery.
