Minimal differences in acute postoperative pain after anterior cruciate ligament reconstruction with quadriceps versus hamstring autograft.

Studies are lacking that evaluate early postoperative pain after all-soft-tissue quadriceps tendon anterior cruciate ligament reconstruction (ACLR), particularly in young patients. The purpose of this study was to investigate differences in early postoperative pain between adolescent patients undergoing ACLR with quadriceps tendon versus hamstring autograft. A retrospective review was performed of 60 patients (mean age, 15.6 ± 1.3 years) who underwent ACLR using either quadriceps tendon ( n  = 31) or hamstring ( n  = 29) autografts between January 2017 and February 2020. Intraoperative and postoperative milligram morphine equivalents (MMEs), postanesthesia care unit (PACU) length of stay and PACU pain scores were recorded. Pain scores and supplemental oxycodone use were recorded on postoperative days (POD) 1-3. Differences were compared between the two groups. There were no statistically significant differences in age, sex, body mass index or concomitant meniscus repairs between the two groups ( P  > 0.05). There were no statistically significant differences in intraoperative MMEs, PACU MMEs or PACU length of stay between groups ( P  > 0.05). There were no statistically significant differences in maximum PACU pain scores (3.7 ± 3.0 vs. 3.8 ± 3.2; P  = 0.89). Maximum pain scores on POD 1-3 were similar between groups ( P  > 0.05). There were no statistically significant differences in supplemental oxycodone doses between groups on POD 1-3 ( P  > 0.05). Adolescent patients undergoing ACLR with quadriceps tendon and hamstring autografts have similar pain levels and opioid use in the early postoperative period.
