BACKGROUND Deep postoperative and hematogenous prosthesis infections may be treated with retention of the prosthesis, if the prosthesis is stable. How long the infection may be present to preclude a good result is unclear. PATIENTS AND METHODS We retrospectively studied 89 deep-infected stable prostheses from 69 total hip replacements and 20 total knee replacements. There were 83 early or del...

Despite improvements in glenoid prosthesis design, materials and surgical techniques, complications related to the glenoid component continue to be a leading cause of failure after total shoulder arthroplasty. Although previously felt to be of little clinical significance, radiolucent lines around the glenoid prosthesis are now recognized as a sign of impending mid and long term fixation proble...

BACKGROUND A 66-year-old male with a history of severe ischemic myopathy and renal failure underwent a combined heart and kidney transplant. Postoperative failure of the transplanted kidney eventually led to the need for peritoneal dialysis (PD). METHODS After one month, the PD catheter was laparoscopically repositioned after it was found to have migrated from its correct position in the pelv...

Metal sensitivity, as measured by an in-vitro assay on peripheral blood lymphocytes, was evaluated in patients with failed joint prostheses. Lymphocyte transformation to chromium, cobalt, and nickel was measured in 24 patients having revision surgery for a painful or loose prosthesis and compared with that in 11 patients who had a successful hip prothesis in situ for at least 2 years previously...

Background and purpose - The surgical treatment of periprosthetic knee infection is generally either a partial revision procedure (open debridement and exchange of the tibial insert) or a 2-stage exchange arthroplasty procedure. We describe the failure rates of these procedures on a nationwide basis. Patients and methods - 105 partial revisions (100 patients) and 215 potential 2-stage revision ...

INTRODUCTION Metallosis is a condition characterized by an infiltration of periprosthetic soft tissues and bone by metallic debris resulting from wear or failure of joint arthroplasties. PRESENTATION OF CASE Authors describe a case of a 45-year-old man treated for an osteosarcoma of the distal femur with a modular prosthesis when he was 18 years old, he developed massive metallosis with skin ...

This paper reports a case of fatigue fracture of the femoral component in a cruciate-retaining cemented total knee arthroplasty (TKA). A 64-year-old man had undergone a primary TKA for osteoarthritis 10 years previously at another institution using the PFC-Sigma prosthesis. The patient recovered fully and was back to his regular activities. He presented with a history of sudden onset pain and l...
