We divided 309 patients with an inflammatory arthritis who had undergone primary elbow replacement using the Souter-Strathclyde implant into two groups according to their age. The mean follow-up in the older group (mean age 64 years) was 7.3 years while in the younger patients (mean age 42 years) it was 12 years. Survivorship for three different failure end-points (revision, revision because of...

Aseptic loosening of total joint arthroplastics due to periprosthetic osteolysis is a frequent cause of implant failure. The absence of clinical interventions to arrest or prevent this complication limits the use of total joint replacement especially in younger patients. Here we review recent studies implicating tumor necrosis factor (TNF)-alpha in periprosthetic osteolysis and the rationale fo...

Failure of total hip arthroplasty with acetabular deficiency occurred in 55 patients (60 hips) and was treated with acetabular revision using morsellised allograft and a cemented metal-backed component. A total of 50 patients (55 hips) were available for clinical and radiological evaluation at a mean follow-up of 5.8 years (3 to 9.5). No hip required further revision of the acetabular component...

In this study, porous-coated, fixed with screwed-system femoral prosthesis and total hip prosthesis composed of screwed-system acetabular cup were applied on 21 dogs of different breeds, sexes and ages. Total hip arthroplasty (THA) was applied as one sided in all cases. In 7 cases luxation occured and in 5 of them the prostheses were taken out. One of the cases had a second operation for disloc...

In total knee arthroplasty, infection has always been cited as being the number one cause of failure. However, more recent studies have shown aseptic loosening as the top reason for failure now. Proper cement technique is an important factor in reducing the occurrence of aseptic loosening. Clean and dried bone are important in achieving rigid cement fixation. Subchondral cysts may be hidden bel...

Introduction: Aseptic loosening of the femoral component continues to be a major long-term complication across a wide range of designs in total hip arthroplasty (THA). Early debonding at the stem/cement interface is emerging as an alarming problem [1] with the roughened surface finishes currently popular in clinical practice. The onset of stem/cement interface radiolucency is commonly regarded ...

BACKGROUND Trabecular metal (TM)-coated acetabular components are increasingly used in both primary and revision total hip arthroplasty (THA). However, previous studies assessing TM acetabular components have been small single-center cohorts with most lacking a control group. We compared revision rates following primary THA between TM and non-TM-coated acetabular components. METHODS A retrosp...
