Abstract
Introduction
Hemophilia arthropathy often occurs in the ankle, knee and elbow. In contrast, hemophilic arthropathy in the hip is rare. We report short-term results of total hip arthroplasty (THA) in patients with hemophilia.
Method
Four primary THAs performed in four hemophilic patients from 2007 to 2015 were reviewed retrospectively. Two patients underwent cementless THA, and two patients had cemented THA. All patients had hemophilia A, and clotting factor replacement was performed perioperatively. Blood loss, surgery duration, complications, pre- and post-operative range of motion, and the pre- and post-operative Japanese Orthopedic Association (JOA) score were assessed.
Results
Mean age at time of surgery was 54.8 years (range 33–74 years). Mean duration of follow-up was 29.8 months (range 3–60 months). Mean perioperative blood loss was 798 ml (range 620–953 ml). No infection occurred. Mean flexion improved from 63.8° preoperatively (range 30–95°) to 83.8° postoperatively (range 60–95°). Mean abduction improved from 8.8° preoperatively (range 0–20°) to 25° postoperatively (range 10–40°). The mean JOA score improved from 47.5 preoperatively (range 35–57) to 87.5 postoperatively (range 67–100).
Conclusion
THAs in patients with hemophilia can be successful and result in pain relief and functional improvement, as long as clotting factor replacement is performed adequately.
