Official Title: Do We Need High-Flexing Total Knee Arthroplasty to Improve the Survivorship and to Decrease the Incidence of Osteolysis? A Minimum of Ten Years of Follow-up

Brief Summary: The purpose of this study is to determine if there are any clinical or ROM differences in total knee arthroplasty with standard NexGen LPS prosthesis and NexGen LPS-Flex prosthesis.

Detailed Summary: We therefore hypothesized: (1) the survival of the NexGen LPS-Flex prosthesis is better than standard NexGen LPS prosthesis; (2) knee function and range of motion after clinical assessment will be better in the NexGen LPS-Flex group; and (3) the incidence of osteolysis will be lower in the NexGen LPS-Flex prosthesis than standard NexGTne LPS prosthesis.

Current Primary Outcome: Improvement in Knee Society Knee Score [ Time Frame: 10 years ]

change in knee score will be compared with initial score, until mean follow up of 10.3 year


Original Primary Outcome: Same as current

Current Secondary Outcome: Improvement in the range of motion [ Time Frame: 10 years ]

change in the range of motion of knee joint will be compared with the initial value, until mean follow up of 10.3 years


Original Secondary Outcome: Same as current
