Isoelastic uncemented hip arthroplasty--early experience.

With the increasing failure rae with time of cemented total hip arthroplasty there is a growing interest in uncemented total joint replacement. This review of 88 Isoelastic total hip arthroplasties, and 28 Isoelastic hemiarthroplasties suggests that this implant gives results comparable with cemented total hip arthroplasty at a similar time. The Isoelastic hip replacement system uses uncemented components that have been designed to closely approximate the biomechanical properties of the bone into which they are implanted. The surgical technique is demanding, and orthopaedic surgeons who anticipate using uncemented implants should receive thorough training before embarking on an implantation.
