Abstract: | We examined the clinical and radiographic results of 93 patients affected by knee arthritis or osteonecrosis subjected to
unilateral cementless mobile-bearing total knee arthroplasty with the LCS prothesis (Depuy/Johnson & Johnson). The mean follow-up
was 9.5 years (range, 7–12 years). Clinical evaluation was performed using the Knee Society rating system, while radiographic
evaluation was done according to the Knee Society roentgenographic system. At the latest follow-up, the mean knee score was
87 points: the functional score improved from 40 to 90. Radiolucent lines were small and not progressive. The implant survival
at 12 years was 88%. Six knees (7%) required revision for implant-related problems. We conclude that the mobile-bearing prosthesis
is a successful device even at long-term follow-up. |
