Experience with total hip arthroplasty in Greece, the first 20 years. A particular reference to long-term results with the McKee-Farrar technique.

Total hip arthroplasty was introduced early in Greece (1966-1967) and was initially performed in very small numbers. However, even after the difficult early period, statistics are low compared to other countries. An estimate brings the total number of operations during a 20-year period to 9000 with a rate in recent years of 1000 per year. An early series of 143 arthroplasties (122 patients), mainly of the McKee-Farrar metal-to-metal technique, was reviewed. A final group of 52 arthroplasties, all primary prostheses of the McKee-Farrar type, were assessed with a follow-up period ranging from 12 to 20 years postoperatively. In the surviving cases, 53% were pain-free, and, in 79%, useful motion was maintained. The roentgenographic results were less satisfying but a fair roentgenographic picture did not preclude a good or very good clinical and functional outcome. Although the metal-to-metal technique now appears to be more of historic value, long-term results with this type of implant offer grounds for comparison with current cemented techniques.
