Introduction |
The outpatient prescription of morphine is not without risk and its use following arthroscopic ankle surgery is increasingly frequent. The goal of this study was to evaluate the impact of morphine on postoperative pain following arthroscopic lateral ankle ligament repair. The secondary goal was to identify the adverse effects of morphine.
Materials and methods |
This is a retrospective case-control study of prospective data from 62 patients who underwent primary reconstruction of the lateral ankle ligaments between January 2022 and May 2024. The patients were divided into two groups: those with «no morphine» (31 patients who underwent surgery before April 1 2023) and those «with morphine» (31 patients who underwent surgery after April 1, 2023), paired for age, sex, preoperative Foot and Ankle Outcome Score (FAOS), preoperative Cumberland Ankle Instability Tool (CAIT) score and the grade of the anterior talofibular ligament (ATFL) tear. The main evaluation criterion was pain measured by the visual analog scale (VAS) on D+0 evening, D+0night, D+1, D+2 and D+3, and analyzed in relation to the threshold of Pain Acceptable Symptom state (PASS). The adverse effects of morphine were secondary criteria.
Results |
The mean age of the patients was 34.8 years old (±10,4). The postoperative VAS values (D+0 evening and night, D+1, D+2, D+3) were not significantly different between the groups (p > 0.05). On univariate analysis male gender was associated with a significant decrease in pain on D+3 (β = −1.3; IC95% [−2,4; −0.07], p = 0.043). The threshold of the PASS for the VAS was similar in both groups, with no significant difference (p > 0.05). Adverse effects such as nausea and dizziness were comparable between the groups (p > 0.05).
Conclusion |
The prescription of morphine following arthroscopic lateral ankle ligament reconstruction does not significantly decrease early postoperative pain. The incidence of adverse effects does not increase with the prescription of morphine.
Level of evidence |
III; case control studies.
