简要总结
Total knee arthroplasty (TKA) is one the most common surgical treatments performed for end stage degenerative arthritis of the knee. More than 700,000 procedures are currently performed yearly in the United States. This procedure usually results in moderate-to-severe pain in the immediate post-operative period. Optimal pain control may allow early mobilization, accelerate rehabilitation, improve patient satisfaction, decrease length-of-stay, and optimize functional outcomes. The challenge, however, is to manage pain with alternative methods, reducing the role of opiate medications, which are highly addictive with myriad side effects.
In this prospective randomized double-blinded controlled study, the investigators aim to evaluate the benefits of an over-the-counter (OTC) transdermal CBD preparation in patients undergoing primary total knee arthroplasty as a novel adjunct to the standard multi-modal analgesic regimen, to reduce postoperative pain and reduce the need for opiates after total knee arthroplasty.
