Keywords: Cementless; hip dysplasia; hip dislocation; total hip arthroplasty.


Objectives: We evaluated the clinical and radiographic results of exclusively the same type and standard sized cementless total hip prostheses applied to all dysplastic and dislocated hips.
Patients and methods: In this study, we retrospectively reviewed 69 patients’ (63 females, 6 males; mean age 45.6 years; range 20 to 72 years) 103 dysplastic or dislocated hips on which cementless total hip arthroplasty was performed between January 1998 and January 2006. The mean duration of follow-up was 7.2 years (range 2.0-10.1 years). Eighteen hips (17%) were type I, 29 hips (28%) were type II, 23 hips (22%) were type III and 33 hips (32%) were type IV according to the Crowe classification. Functional and clinical analyses were performed by Harris hip scores. At the last follow-up, the patients were asked whether they were satisfied or not after the operation.
Results: The average preoperative Harris hip score of 39.3 was progressed to 89.5 at the latest follow-ups (p<0.001). Sixty patients (86.9%) reported that they were satisfied after surgery. We observed 41 (39.8%) complications in total, nine of which were intraoperative. There were no findings of symptomatic septic or aseptic loosening at the latest follow-ups.
Conclusion: Cementless total hip arthroplasty is an effective procedure for dysplastic and dislocated hips.
