Abstract:
[Objective]To summarize the experiences of total hip replacement with cementless joint components in the treatment of osteoarthritis secondary to acetabular dysplasia in adults and to evaluate its early effect. [Method]From March 2000 to March 2007, thirty hips in 25 adult patients with osteoarthritis secondary to acetabular dysplasia undergoing total hip replacement with cementless joint components were included in this study. Of the patients, 5 were male and 20 were female.Their ages ranged from 35 to 55 years with an average age of 55 years. The patients mainly complained of pain and claudication. According to the Hartofilakidis classification , Semi-dislocation occurred in 21 hips and high-dislocation in 9 hips.Five patients underwent bilateral total hip replacements and twenty patients had unilateral total hip replacement.[Result]The duration of follow-up ranged from 8 months to 7 years ( average 3 years and 9 months ) . The average Harris score was increased from 36.09 to 88.21 points, They could take care of themselves and returned to their previous job. All the patients were pain-free and there was no sign of aseptic looseing or subsidence.[Conclusion]Total hip replacement with cementless joint components is an effective method for the treatment of osteoarthritis secondray to acetabular dysplasia in adults.The key point to the success for operation are appropriate cementless joint components, deepened medial wall of the acetabulum and improved the techniques of bone graft in the true acetabulum.
