Eligibility
Inclusion criteria
Inclusion criteria: RSA studies: 1. Primary Total Knee replacement; 2. Minimal RSA follow-up of 1 year, measuring prosthesis micromotion. Survival / cohort studies: 1. Primary Total Knee Replacement; 2. Follow up of 5, 10, 15, 20 or 25 years; 3. Endpoint aseptic loosening of tibial: A. For which revision surgery was undertaken; B. For which revision surgery was indicated, but could not be undertaken (patient decline, poor general health). 4. Survival analysis or % revised due to aseptic loosening on total: A. Available for specific prosthetic design and fixation; B. At specific follow up (see point 2).
Exclusion criteria
Exclusion criteria: RSA studies: 1. Non-clinical studies: Animal, experimental set up, phantom. Survival / cohort studies: 1. Minimal 75 arthroplasties at baseline.
