Cementless Revision Operations of Loosened Cemented Hip Arthroplasties: Ten Years Experience

Abstract

We report on ten years’ experience with cementless hiparthroplasty in revision-operations of loosened cemented hiparthroplasties. In about 25 percent of cases admitted to our hospital, patients had been previously operated on more than once, and nearly 9 percent had a bacteriologically proven infection. The reconstruction of acetabulum and femur for implantation of a cementless prosthesis is performed by means of homologous bonegraft stored in a bonebank. The bone is stored at -70 to -80 °C. A condition of an adequate ingrowth to both autologous or homologous bonegraft is that the implant is resting well in its bedding. With the aid of examples the results of the above technique are shown. Since April 1987 the stem is coated with Titanium powder in the proximal part. Since 1987 several methods have been utilized to minimize homologous blood transfusions (i.e. plasmapheresis, preoperative haemodilution; intra- and postoperative cell-saving).
