Abstract:

BACKGROUND: Total hip arthroplasty (THA) for adult developmental dysplasia of the hip (DDH) can effectively relieve hip pain, improve hip function and quality of patient life.
OBJECTIVE: To comprehensively evaluate the effects of THA in treating osteoarthritis secondary to DDH.
METHODS: Articles of clinical studies regarding THA for osteoarthritis secondary to DDH published between January 2001 and June 2010 were searched from CNKI database. Repetitive studies and review articles were excluded. Included articles were evaluated and summarized.  
RESULTS AND CONCLUSION: By reading titles and abstracts, 50 articles were collected, and 16 were included in the final analysis. The Harris hip scores, recent excellent and good rate, and satisfaction degree were analyzed. Results showed that THA is an effective method to treat osteoarthritis secondary to DDH. However, THA is difficult to operate. Deepening the acetabular reaming, firmly placing the acetabular component in the true acetabulum, and reforming the anatomical rotational center are important for successful THA, which improves effects of THA.
