We studied the results of 25 rotational acetabular osteotomies (RAO) for advanced osteoarthritis of the hip. All patients were female. The average age at operation was 43 years (range : 30 to 55 years). The average duration of follow-up was 3.2 years (range : 1 to 7.3 years).
The CE angle, AC angle, and AHI significantly improved in all patients after surgery. At the time of follow-up, the average Japanese Orthopaedic Association hip score improved from 64 to 89. Five joints showed progression of degenerative changes. These patients indicated advanced osteoarthritis also in the opposite hip. No patient had secondary total hip arthroplasty (THA).
We conclude that RAO can improve the advanced osteoarthritis of the hip and delay the indication for THA.
