Clinical Results of Rotational Acetabular Osteotomy

We performed rotational acetabular ostetomy (RAO) on 14 patients. All subjects were women, their ages at surgery ranged from 25 to 52 years, and the follow-up period averaged 4 years. We compared the CE angle and AC angle before and after surgery.All patients showed improvement of both the CE angle and AC angle. The mean CE angle improved from 4.4 degrees to 24.6 degrees (p<0.01), and the mean AC angle from 23.8 degrees to 8.3 degrees (p<0.01). The range of motion (flexion and abduction) did not decrease alter surgery. 1 patient showed progression of the degenerative change by the necrosis of the rotated bone.The clinical results for RAO were not significant compared to early stage OA (11 hips) and advanced OA (4 hips).

Clinical Results of Bilateral Total Knee Arthroplasties Comparison of Simultaneous and Staged Knee Replacements

The purpose of this study was to evaluate outcome of bilateral total knee arthroplasties (TKAs) in two groups of patients: Group A had simultaneous arthroplasty of both knees, and Group B had staged bilateral arthroplasty.Bilateral (TKAs) were performed in fifteen patients with severe rheumatoid arthritis (4 cases) and osteoarthritis (11 cases). Group A (8 patients) had both knees replaced simultaneously in one operation. Group B (7 patients) had two operation in a staged procedure. The postoperative mobility was analyzed in the two groups of patients who were similar with respect to age, type of arthritis, preoperative range of motion, and postoperative management.In this small series of cases there was a significantly shorter hospitalization period, and cheaper costs in Group A.
