Evaluation of Early Migration of Medially Stabilized Arthroplasty as a Predictor of Long Time Survivorship (Implant Design Study)
In Brief
A clinical study evaluating Medacta International, GMK Sphere medially stabilized knee for Knee Osteoarthritis. Completed, enrolled 44 participants across 1 site.
Detailed Summary
Total joint replacement is an efficacious treatment for osteoarthritis of hips and knees. Both total knee replacement (TKR) and total hip replacements (THR) have excellent implant survivorship. However, patient satisfaction is lower in TKR than THR. A possible cause of the discrepancy is the unnatural knee kinematics after TKR. Various implants designs have been developed to solve the problem. However, most of their designs are based on experimental data and little has been studied about their actual performance in vivo. In this study, the investigators will analyze the in vivo stability of the Global Medacta Knee Sphere (GMK Sphere) implant. Migration of the implants will be monitored with a high precision measuring method called Radiostereometric Analysis (RSA). The investigators assume the investigators study will contribute the development of more satisfying knee implants.
