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 implant designs have been developed to solve the problem. However, most of the designs are based on experimental data and not on in vivo kinematics. In this study, we will analyze the in vivo kinematics of the Global Medacta Knee Sphere (GMK Sphere) implant and compare it with a well documented design and implant (NexGen Cruciate Retaining (CR), Zimmer Biomet). We assume our study will contribute to the development of more satisfying knee implants.
