Cementless total knee arthroplasty with Profix: a 8- to 10-year follow-up study.
A consecutive series of 115 cementless Profix (Smith and Nephew, Memphis, USA) Total Knee Arthroplasties performed in 113 patients were followed in order to determine the functional results and survivorship at 8 to 10 years. All patients were included in a prospective database and were reviewed annually until final follow-up. Patients overall satisfaction was excellent or good in 91.3% of cases. The mean Knee Society's knee and function scores increased respectively from 49.3 and 36.7 preoperatively to 93.1 and 82.2 postoperatively. The Kaplan-Meier estimate of implant survival at 10 years was 97.1%. Two patients underwent revision and were considered as failures. One patient had a fracture of the medial condyle at 4 days post-surgery, and the other was revised for aseptic loosening of the tibial component at 6 years post-surgery. On the basis of this long-term follow-up study, we can conclude that the Profix Total Knee System is effective and safe.
