Postoperative Multimodal Pain Management and Opioid Consumption in Arthroscopy Clinical Trials: A Systematic Review.

PURPOSE

To provide an updated review of multimodal pain management in arthroscopic surgery by evaluating pain and opioid consumption after shoulder, knee, and hip arthroscopy.

METHODS

A comprehensive literature search was performed to identify randomized controlled trials (RCTs) investigating multimodal pain management after shoulder, knee, and hip arthroscopy. Articles were identified from January 2011 through December 2020 using various databases. As the primary outcome variables of this study, differences in postoperative pain and opioid consumption volumes were summarized from all reported postoperative time points.

RESULTS

37 shoulder, 28 knee, and 8 hip arthroscopy RCTs were included in the study. The most frequent bias present in the included RCTs was incomplete outcome data (58%), while group allocation concealment was the least frequent bias (15%). Qualitative analysis of rotator cuff repair ( = 12), anterior cruciate ligament reconstruction ( = 11), meniscectomy ( = 5), femoroacetabular impingement ( = 2), oral medications ( = 8), postoperative interventions ( = 10), and nonpharmacological interventions ( = 6) was performed.

CONCLUSIONS

Many multimodal pain management protocols offer improved pain control and decreased opioid consumption after arthroscopic surgery. On the basis of the current literature, the evidence supports an interscalene nerve block with a dexamethasone-dexmedetomidine combination for rotator cuff repair, a proximal continuous adductor canal block for anterior cruciate ligament reconstruction, and local infiltration analgesia (e.g., periacetabular injection with 20 mL of .5% bupivacaine) for hip arthroscopy. When evaluating oral medication, the evidence supports 150 mg Pregabalin for shoulder arthroscopy, 400 mg Celecoxib for knee arthroscopy, and 200 mg Celecoxib for hip arthroscopy, all taken preoperatively. There is promising evidence for the use of various nonpharmacological modalities, specifically preoperative opioid education for rotator cuff repair patients; however, more clinical trials that evaluate nonpharmacological interventions should be performed.
