Study Comparing Medial Pivot and Single Radius Knee Implants for Adults Undergoing Total Knee Replacement

What this Trial Is About

Researchers are comparing two types of knee implant designs, medial pivot and single radius, used in total knee replacement surgery for adults with degenerative joint disease. The study aims to evaluate which design may lead to better knee motion, improved clinical outcomes, and higher patient satisfaction. This research is a single center, cohort study involving 100 adult subjects who will receive one of the two implant systems. Participants will undergo primary total knee arthroplasty using either the MicroPort Medial Pivot Knee System or the Stryker Triathlon Tritanium Knee System. Follow-up visits are scheduled pre-operatively, at the time of surgery, and post-operatively at 6 weeks, 6 months, 12 months, 24 months, 36 months, and 60 months. These visits will track recovery and implant performance over time. During the study, participants will have clinical evaluations, patient-reported outcome assessments, and specialized gait laboratory analyses to measure knee mechanics, muscle strength, range of motion, and function. Researchers will monitor implant survivorship, complications, and changes in knee scores and patient quality of life. The study will last up to five years, including long-term follow-up visits to assess outcomes and safety.
