Knee Society Scoring [ Time Frame: five years after surgery ]
was used for evaluating the function of the knee and high scores indicated better knee function
Same as current

Pain [ Time Frame: five years after surgery ]
Pain was evaluated with a Visual Analogue Scale (VAS) with scores ranging from zero to 10ten (0 for no pain and 10 for intolerable pain).

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.
