We present the results of 228 consecutive Charnley low friction hip
arthroplasties, performed in 193 patients, between July 1972 and December 1976.
Unusually for this time, all hips were inserted by the posterior approach
without a trochanteric osteotomy. All patients were enrolled into a prospective
study; both preoperative and postoperative clinical and radiologic findings were
recorded. This series was independently reviewed in 1985 (Atrah SGK. Long-term
follow-up of Charnley total hip replacement through posterior approach. MSc
thesis, University of London, 1987) and again in 2002. The preoperative and
perioperative findings were similar to contemporary series. Implant positioning
was also assessed. Because of our stable population, only 2 patients were lost
to follow-up. Our survivorship results show a 10-year survival of 93%
deteriorating to a 30-year survival of 73% (+/-6.1). The survivors were assessed
radiologically and scored clinically using the Merle d'Aubigné-Postel score with
a mean value of 12. The reason for revision was also recorded. These results are
comparable to other studies and justify the use of the posterior approach.
