Official title: Multiprofen-CC™ to Reduce Pain After Total Knee Arthroplasty: A Blinded Randomized Controlled Trial

Status Not yet recruiting

Clinical Trial Summary

Total knee arthroplasty is a surgical treatment which involves replacing the damaged articular cartilage of the knee joint with an artificial prosthetic in end-stage knee osteoarthritis. Although total knee arthroplasties are mostly successful, approximately 1 in 5 patients are unsatisfied with their outcomes with 16-33% of patients of patients experiencing lasting pain following total knee arthroplasty. Multiprofen-CC™ is a compounded topical analgesic currently available to healthcare professionals for prescription in patients experiencing localized musculoskeletal pain. To date there has been no evidence-based guidance generated to evaluate the efficacy of Multiprofen-CC™ in osteoarthritis patients. This study will test, in patients with end-stage knee osteoarthritis undergoing total knee arthroplasty, if the use of topical Multiprofen-CC™ in addition to standard of care pain management is more effective in controlling knee pain and reducing opioid use compared to placebo plus standard care alone.

Clinical Trial Description

Total knee replacement, also known as total knee arthroplasty (TKA), is a surgical procedure aimed at alleviating pain and improving joint function in individuals with severe knee joint damage, often caused by conditions like osteoarthritis (OA) While TKAs generally yield positive results, a significant amount of patients express dissatisfaction with their outcomes, with some continuing to experience persistent pain after surgery. Opioids are very commonly prescribed for postsurgical pan, but they can cause a host of unwanted side effects. Orthopaedic surgeons prescribe opioids more frequently than in any other surgical speciality. This is a rising concern to the healthcare system as it may promote the development of opioid use disorder. There is a need for alternative therapies to opioid prescribing in patients having knee surgery to reduce the extensive health risks associated with opioid medications. Multiprofen-CC™ is a multimodal topical cream including ingredients ketoprofen (10%), baclofen (5%), amitriptyline (2%), and lidocaine (5%). Healthcare professionals have the option to prescribe it to patients who are encountering localized musculoskeletal pain. To date there has been no evidence-based guidance generated to evaluate the efficacy of Multiprofen-CC™ in OA patients although there is compelling evidence that its medicinal ingredients are effective in pain relief. The aim of the proposed study is to determine if, in patients with end-stage knee OA undergoing TKA, the use of topical Multiprofen-CC™ in addition to standard of care pain management is more effective in controlling knee pain and reducing opioid use compared to placebo plus standard care alone during a 3 month follow-up period. Secondary objectives include determining the effects of Multiprofen-CC™ compared to placebo on health-related quality of life and satisfaction with pain management, and we will also identify adverse events. ;
