RESULTS AFTER CEMENTLESS REVISION ARTHROP LASTY OF THE ACETABULAR COMPONENT

The great number of hip revision arthroplasties and the cementless fix ation of arthroplasties has led to more and cementless hip revision op erations with bone transplantation. This retrospective study shows the results of a clinical and radiological fellow-up of 34 patients with an average age of 71 years and 4 months at their hip revision arthropl asty. The subjective and clinical result in the Harris-Hip-Score 3 yea rs and 9 months (1 year 4 months - 6 years 3 months) after surgery sho ws 67% of the patients content with the result of the revision arthrop lasty. The Harris-Hip-Score shows an average of 41.1 points preoperati vely and 73.2 points at the follow-up examination. The loosing-rate wa s 11.8%, all arthroplasties which seemed loosened radiologically had a lso a bad result clinically. No correlation could be shown between the age of the patients and the clinical results as well as between an ad ditional stem revision (15 patients) and the clinical result in the Ha rris-Hip-Score. All revision operations were done with bone transplant ation and demonstrate, that the concept of cementless fixation of acet abular component gives satisfactory results.
