Comparing Fixed-bearing Versus Mobile-bearing Prosthesis in Total Knee Arthroplasty: A Prospective Randomized Trial

Study of Prosthesis in Total Knee Arthroplasty

The purpose of this study is to determine which prosthesis is better in total knee arthroplasty

Theoretical advantages of mobile-bearing devices led surgeons to use these prostheses instead of fixed-bearing devices as traditional implants. This study was designed to compare Fixed-bearing versus Mobile-bearing Prosthesis in Total Knee Arthroplasty through a five-year follow-up.

Inclusion Criteria:

• Patients with expected primary total knee arthroplasty

Exclusion Criteria:

• Mediolateral instability
• Infective arthritis
• Severe deformity
• Revision
