Mid-term follow up study of THA (MX-1)

Abstract

Twenty three patients were treated by THA (cemented MX-1). There were fifteen cases of severe coxarthrosis, six cases of RA and two cases of aseptic necrosis of the femoral head. The mean follow-up period was four years and nine months. The avarage JOA score was 33.6 points preoperatively, compared with 79.7 points postoperatively. The improvement in the JOA score averaged 46.1 points. Radiologic evaluation of THA resulted in a mean score of -4.2 points.
