There are few reports in the literature that deal with the results of total knee arthroplasty in the younger patient. The present study was undertaken to evaluate the results of total knee arthroplasty in patients under the age of 55 years. Ninety-three knee arthroplasties in 62 patients were performed between 1974 and 1982. ⋯ Survivorship analysis resulted in a cumulative survivorship rate of 96% at ten years for the entire group. These results are comparable to the long-term results of total knee arthroplasty in the older patient and better than the results of total hip arthroplasty in the younger patient. Total knee arthroplasty in the younger patient is a reliable and durable procedure but should be used with caution despite the excellent results reported here.
