Abstract: | Revision rates, complication rates, and the bone-cement interface reaction of 1,069 condylar total knee replacements were reviewed to help decide if conventional total knee replacement continues to be appropriate for the older low-demand patient. This knee replacement series was also compared with two published series of total hip replacements from the same institution. The conclusions are (1) in medium-term follow-up, total knee replacement is as good as or superior to total hip replacement and (2) based on bone-cement interface analysis, survival of total knee replacement is expected to be superior to conventional total hip replacement ten years postoperatively. |
