Objectives: The purpose of this study is to evaluate the ability of TKA patients to return to sports and the tolerance of sports activities on the mid term survivorship of the prosthesis.
Study Design & Methods: : From January 2001 to January 2008, 500 patients received 602 "Rotating Concave-Convex" or ROCC® (Biomet) posterior cruciate ligament-substituting MBTKAs. Clinical and radiological outcomes were assessed at baseline and postoperatively using the Knee Society (KS) Knee and Function and activity by the University of California at Los Angeles (UCLA) scale.
Results: A total 584 …show more content…
At last follow-up, 355 patients (71%) could perform regular physical activities, with a mean UCLA rating of 7.3±1/10 (5 to 10). 133 patients (26%) could perform sport activities at a level equal or greater than 8/10 on the UCLA rating score. In 96 of these 133 knees (72%), the patient had more than one sports activity (total = 233 itemized activities). In 103 of these 133 cases, UCLA rating was 9/10 (backpacking, dancing, cross country skiing, aerobics, rollerblade running, horse-riding or jumping-show or heavy farm labor), and in 30, 10/10 (tennis, marathon, downhill skiing, alpine glacier hiking, parasailing). Kaplan-Meier 13-year survivorship with revision for aseptic loosening as end-point was 99.4% (95% CI, 99.8-100). On the 3 loosenings occuring during this period , none occured on patients with intense activity.
Conclusions: This study reports that return to an intense physical activity is possible after this Mobile bearing Total Knee Arthroplasty and does not compromise the midterm survivorship of the implant
