Registration Number
NCT04613024
Lead Sponsor
Stanford University
Brief Summary

The purpose of this study is to evaluate the effects of topiramate (TPM) in obese patients with respect to weight loss and pain after total joint replacement surgery

Detailed Description

Investigator hypothesize that low dose peri-operative topiramate is superior to gabapentin in reducing postoperative pain and opioid consumption after primary TJA with a more favorable side effect profile that will facilitate patient optimization via pre- and postoperative weight loss.

Primary Outcome Measures
NameTimeMethod
Determine the reduction in Opioid Consumption3 months

Postoperative morphine equivalent opiate use and opiate refill requests after discharge will be compared post randomization to receive one of the two medications for multimodal pain control.

Evaluate the Side Effect Profiles of Topiramate3 months

Perioperative weight change experienced by patients will be compared after randomization to receive one of the two medications. Weight change is measured in lbs

Evaluate the Side Effect Profiles of gabapentin3 months

Perioperative weight change experienced by patients will be compared after randomization to receive one of the two medications. Weight change is measured in lbs

Secondary Outcome Measures
NameTimeMethod
Harris hip score - Evaluate Short-term Arthroplasty-related Outcomes and Complications while on Topiramate or Gabapentin1 week

Harris hip score will be calculated after randomization at the pre-operative visit. The maximum score possible is 100. Results can be interpreted with the following: \<70 = poor result; 70-80 = fair, 80-90 = good, and 90-100 = excellent.

WOMAC score Evaluate Short-term Arthroplasty-related Outcomes and Complications while on Topiramate or Gabapentin at 6 weeks6 week

WOMAC score will be calculated after surgery. The test questions are scored on a scale of 0-4, which correspond to: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4).

The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function. Usually a sum of the scores for all three subscales gives a total WOMAC score, however there are other methods that have been used to combine scores
