IntroductionThe use of periarticular multimodal analgesia injections is increasing and has become commonplace in some surgeries. However, there is no data on the effectiveness of local periarticular multimodal analgesia for tibial plateau fractures. We hypothesized that closed tibial plateau fracture patients receiving the local multimodal analgesic medications would experience a decrease in VAS pain scores.MethodsPatients aged between 18 and 79 with an isolated closed tibial plateau fracture (AO 41-B and C) were prospectively enrolled and randomized in a 1:1 double blinded fashion to either a placebo or active medication treatment arm. After ORIF, gel-foam sponges soaked in either multimodal analgesic solution or normal saline. Patients were followed for 24 h post-operatively with Visual Analog pain Scores (VAS). Patients were monitored post-operatively for complications including compartment syndrome, infection, and non-union.ResultsThe planned study was terminated prior to completion due to higher than anticipated rates of infection (18%), distributed equally among active (3) and placebo (2) groups, raising concerns that this may have been due to the presence of the delivery device. Twenty-eight patients were enrolled, 15 in the active group and 13 in the placebo group. Patients in the active medication group had significantly decreased pain scores at hours 4 (p = 0.005, 4.2 vs 6.9), 8 (p = 0.05, 5 vs 7), and 12 (p = 0.02, 3.8 vs 6.2). Pain scores at hours 16 (p = 0.10, 4.5 vs 6.5), 20 (p = 0.08, 4.6 vs 6.4), and 24 (p = 0.10, 4.8 vs 6.5) were also decreased but did not reach significance.DiscussionThe use of local multimodal periarticular analgesic for closed tibial plateau fractures appears to be beneficial for short-term pain control post-operatively. Concerns regarding an implantable delivery vehicle leading to infection has warranted a change in method of drug administration. Completion of the full study will permit us to validate or refute these findings.Level Of EvidenceTherapeutic Level 1.Copyright © 2022. Published by Elsevier Ltd.
