Study Comparing Medial Pivot and Ultra-congruent Polyethylene Devices in Total Knee Replacement Surgery for Gonarthrosis

What this Trial Is About

Researchers are comparing two types of polyethylene inserts used in total knee replacement surgery for patients with arthritis. The study focuses on the medial pivot polyethylene and ultra-congruent polyethylene, which serve as the interface between the metallic femoral and tibial components of the prosthetic knee. These inserts aim to provide stability and mimic natural knee movements to improve patient quality of life after surgery. Participants will receive a total knee replacement using either the medial pivot polyethylene or the ultra-congruent polyethylene. Both types are designed to replace knee ligaments and support natural knee motion, but they differ in design. The study randomly assigns participants to one of these two groups to compare their outcomes. During the study, participants will be assessed before surgery, at 45 days, and at 12 months. Evaluations include the forgotten joint score, which measures how natural the knee feels, as well as knee mobility, pain levels, and knee function scores. Researchers will also review X-rays to check alignment and complications. The study aims to gather detailed information on knee performance and patient satisfaction over one year after surgery.
