The Denham prosthesis in revision knee surgery: a 10 year follow-up.

We studied the Denham knee prosthesis (Biomet, Warsaw, IN) in revision of total knee arthroplasty (TKA) in situations of extreme bone loss or ligamentous disruption including revision from previous hinged implants. We reviewed 34 patients (38 knees) at an average of 7. 5 years after surgery (range 4-12 years). No patient was lost to follow-up although 15 unrelated deaths occurred during the study. There were six failures, of which five were due to infections in patients who received a revision for infection. A further two patients experienced a poor result. The remaining 30 patients had an excellent or good result. In our setting, the Denham TKA effectively addressed problems of loss of bone stock and ligamentous disruption with simple instrumentation and a remarkably small number of implants.
