Total hip arthroplasty for primary septic arthritis of the hip in adults.

Two-stage total hip arthroplasties (THA) performed after primary septic arthritis of hip were studied to evaluate the surgical outcomes and complications. Of 28 cases, the reinfection rate was 14% and complication rate was 36%. At an average follow-up period of 77 months, the outcome in 22 patients (79%) was rated as good or excellent, 4 as fair, and 2 as poor. Leg length discrepancy improved from a preoperative mean of 2.89 cm to a postoperative mean of 0.61 cm. Despite a higher complication rate, two-stage THA was still deemed a worthy procedure because hip function was significantly improved in patients with primary septic arthritis of the hip.
