Cemented implant fixation design principles have evolved since the 1950s, and various
femoral stem designs are currently in use to provide a stable construct between the implant …

Persistent pain around the greater trochanter is a common complication after total hip
arthroplasty. Restoration of biomechanics such as leg length, femoral und acetabular offset …

Background Short-stem total hip arthroplasty (THA) potentially offers advantages compared
to conventional THA, including sparing bone and soft tissue and being a facilitated and less …

Background Hard-on-hard bearings require a meticulous implantation technique but may be
associated with lower wear rates in young active patients. Among them, metal-on-metal …

Introduction Total hip arthroplasty in patients with altered anatomy of the hip and femur, such
as in congenital dysplasia of the hip, is challenging and often requires specially designed …

Background: Total hip arthroplasties (THAs) bearing is one of the most important factors for
hip replacement because THA survival depends on it. Metal-on-metal (MoM) bearing has …

Purpose Ceramic coatings have been used in metal-on-polyethylene (MOP) hips to reduce
the risk of wear and also infection; the clinical efficacy of this remains unclear. This retrieval …

Introduction This stem was cleared by the FDA in 2002 and has been implanted in
cementless and cemented versions. Despite its long history, there are no long-term clinical …

A considerable number of patients who underwent a 2-stage exchange protocol for
periprosthetic hip joint infection could not complete the second-stage reimplantation. The …

Optimal cementing technique is very important. It is very important to know the concept of
shape-closed fixation and force-closed fixation for cemented femoral stems. Cement cups …
