Long-term Evaluation Protocol (12 Months Postoperative) of Total Knee Prostheses Anatomic With Resurfaced Patella Versus Non-resurfaced Patella in Patients Requiring Total Knee Arthroplasty

Arthroplasty Clinical Trial

Official title:
Long-term Evaluation Protocol (12 Months Postoperative) of Total Knee Prostheses Anatomic With Resurfaced Patella Versus Non-resurfaced Patella in Patients Requiring Total Knee Arthroplasty Prospective, Monocentric, Randomized, Open-label Study

Clinical Trial Summary

Total knee arthroplasty is a frequent surgery in France. It currently represents 70,000 interventions per year. The total knee prosthesis is also called tri-compartmental because it allows articulation between the femur and the tibia but also between the femur and the patella. The patella belongs to the extensor system. It articulates with the femoral trochlea in which it slides. It has an important biomechanical role on the quadriceps strength in addition to allowing flexion-extension movements. In the case of resurfacing, the joint face of the patella is cut off; A convex polyethylene implant is sealed with cement using studs on the same face. In case of non-resurfacing, the surgeon leaves in place the cartilage of the patella which will be in direct contact with the femoral prosthetic trochlea. Both methods have advantages and disadvantages. For some implants, it is recommended to resurface the patella because the implant is not very tolerant with the native patella. Other implants have been designed to be better adapted to the preservation of patellar cartilage. There is currently no evidence that one method is superior to the other on new generation implants known as "patellar friendly". It seems necessary to compare both methods in terms of long-term postsurgery results.

Clinical Trial Description

The analysis of the primary endpoint (International Knee Society score (IKS score)) will be based on the assumption that the postsurgery score will be identical in both groups. The t test for independent samples will be used to test this hypothesis. ;
