From may 2005 25 surface arthroplasties were made in 10 women and 15 men in the age from 23 to 64 years (average 43 years). The main reason for arthroplasty was idiopathic arthritis in 20 patients. 24 ReCap (Biomet) endoprosthesis were implanted. The dysplastic BHR (Smith & Nephew) acetabular component was implanted in one patient because of the deficit of dysplastic acetabulum.
The follow up is from 10 to 20 months (average 11 months). Clinical results in Harris Hip Score is from 90 to 100 points (average 95.8 pts). The average acetabular cup's angle of inclination is 51.2 degrees (from 40 to 77 degrees), and average femoral heads angle is 140.3 degrees (from 131 to 148 degrees). There were not any significant intraoperative and early postoperative complications.
Early clinical results and data from bibliography confirm the value of surface arthroplasty in the treatment of young and active patients. The procedure is technically demanding.
