Joint Replacement Institute

Increasing numbers of patients are undergoing revision surgery. The most frequent cause of failure of a total hip replacement is loosening of the implant in bone which may be caused or aggravated by the wear process. The magnitude of the surgery depends on the complexity of prosthetic removal and restoration of bone deficiency. Revision of a surface replacement is likely to be less formidable because the femur or thigh bone is intact. Revision surgery may require bone grafts from your pelvic area and/or from the bone bank. Custom prostheses may be needed. Like primary surgery, the durability is dependent upon the techniques utilized and revision surgery is technically more difficult although quality results can be achieved. Third and fourth revisions have also been performed. Once again, each revision may have special and more difficult challenges for the surgeon and the patient. Special precautions are mandatory following these types of procedures.

Unlike conventional total hip replacement (THR), hip resurfacing is conservative in that the femoral head and neck of the hip joint are not removed nor is bone removed from the femur. In the case of surface replacement, less bone is also removed from the acetabulum as compared to conventional THR since no polyethylene liner is used.

JRI Research

The staff of JRI is engaged in various research studies, including: improving long term joint replacement durability by selective use of new replacement bearing technology, histological characterization of implant fixation, relationship between wear debris and aseptic loosening.
