[Non-cemented acetabular cup in hip arthroplasty. Prosthesis survival and clinical results after 1-8 years]

This is a retrospective clinical evaluation of 1028 primary hip arthroplasties performed with the non-cemented Harris-Galante I acetabulaer cup. Hospital records regarding all hips operated from July 1985 through March 1992 were evaluated after a median of 48 (12-93) months. Furthermore, questionnaires were sent out to all patients still alive in order to establish the actual function of the hips. At time of evaluation, 43 of the 1028 primary acetabular cups (4.2%) had been or were due to be revised. (20 because of one or more episodes of dislocation or displacement of the cup, 10 due to deep infection, eight following aseptic loosening of the cup, two because of implant failure and three due to other reasons). Four hundred and twenty-six hips were without pain, 274 had only mild or slight pain, whereas 84 experienced moderate or worse pain. We conclude, that the results after non-cemented hemispheric acetabular arthroplasties in this study are satisfying with a low rate of aseptic loosening.
