The articular surface replacement implant recall: a United Kingdom district hospital experience.

We present our experience of the articular surface replacement (ASR) hip and the implant recall process. One hundred and twenty-one ASR components were implanted (21 resurfacing hip arthroplasty (RHA) and 100 ASR/XL modular total hip replacements). At the time of the implant recall in August 2010 there were 111 surviving hips (92%) with a mean follow-up of 44 months.

Reducing the rate of early primary hip dislocation by combining a change in surgical technique and an increase in femoral head diameter to 36 mm.

Introduction: We report how changes to our total hip arthroplasty (THA) surgical practise lead to a decrease in early hip dislocation rates.

Methods: Group B consisted of 421 consecutive primary THA operations performed via a posterior approach. The operative technique included a meticulous repair of the posterior capsule, alignment of the acetabular cup with the transverse acetabular ligament (TAL) and a 36-mm-diameter femoral head.
