Multimodal Nonopioid Pain Protocol Provides Equivalent Pain Versus Opioid Control Following Meniscus Surgery: A Prospective Randomized Controlled Trial

Abstract

Purpose: To assess the effectiveness of a nonopioid pain regimen in controlling postoperative pain as compared with a traditional opioid pain control following primary meniscectomy or meniscal repair.

Methods: Ninety-nine patients undergoing primary meniscectomy or meniscal repair were assessed for participation. A prospective randomized control trial was performed in accordance with the Consolidated Standards of Reporting Trials 2010 statement. The 2 arms of the study included a multimodal nonopioid analgesic protocol and a standard opioid regimen with a primary outcome of postoperative pain level (visual analog scale) for the first 10 days postoperatively. Secondary outcomes included patient-reported outcomes, complications, and patient satisfaction. Randomization was achieved using a random-number generator. Patients were not blinded. Data collection was done by a blinded observer.

Results: Eleven patients did not meet the inclusion criteria, and 27 declined participation. A total of 61 patients were analyzed with 30 randomized to the opioid regimen and 31 randomized to the nonopioid regimen. Patients receiving the nonopioid regimen demonstrated noninferior visual analog scale scores compared with patients who received opioid pain medication (P > .05). No significant differences were found in preoperative (opioid: 58.9 ± 7.0; nonopioid: 58.2 ± 5.5, P = .724) or postoperative (opioid: 59.8 ± 6.5; nonopioid: 54.9 ± 7.1, P = .064) Patient-Reported Outcomes Measurement and Information System Pain Interference Short Form scores. No difference was found in recorded side effects between both groups at any given time point: constipation, nausea, diarrhea, upset stomach, and drowsiness (P > .05).

Conclusions: This study found that a multimodal nonopioid pain protocol provided equivalent pain control and patient outcomes following primary meniscus surgery while having an equivalent side effect profile. All patients reported satisfaction with their pain management without requiring emergency opioid analgesia.

Level of evidence: Level I, prospective randomized controlled trial.
