title: Total hip arthroplasty in Malaysia--the Universiti Kebangsaan Malaysia and Hospital Kuala Lumpur experience.
abstract: The results of 109 primary total hip arthroplasties in 92 patients performed in Hospital Kuala Lumpur from January 1987 to December 1996 were reviewed after a mean follow-up of 30.8 months. There were 22 males and 70 females with the average age of 49.9 years (range 19 to 94 years). Chinese females comprised the largest group of patients (52.2%). Avascular necrosis was the most common diagnosis (33.1%) followed by hip dysplasia and primary osteoarthritis (17.4%). The procedure was performed more on the right hip (64.2%) compared to the left (35.8%). All patients received prophylactic antibiotics but none were given deep vein thrombosis prophylaxis. The Charnley prosthesis was most commonly used and the majority of the arthroplasties were cemented (60.5%). About 80% of the THA were performed via the lateral approach. The functional hip score improved from an average of 8.9 to 15.0 with 66.3% of the patients categorized as good and excellent results. There were 16 patients (17.4%) with poor outcome. The most common complications encountered were dislocation (10.1%), aseptic loosening (9.2%) and periprosthetic fracture (5.5%). Other complications were deep infection (1.8%), deep vein thrombosis (0.9%), trochanteric osteotomy complications (1.8%), superficial infection (7.3%), urinary tract infection (5.5%), pressure sore (3.7%) and respiratory complication (1.8%). Fifteen hips (13.8%) required revision. The causes for revision were aseptic loosening, dislocation and infection. Technical anomalies were recognized as one of the factors contributing to poor results. Five-year survival rate was 87.3%. Better results can be expected with increasing experience and technical skulls.
