Survival, clinical and radiological outcome of the Zweymüller SL/Bicon-Plus total hip arthroplasty: a 15-year follow-up study.

Aim: The primary aim of this study is to analyse the long-term results of the third generation of the "Zweymüller" total hip arthroplasty (THA) comprising the SL-Plus Stem and the Bicon-Plus cup.

Methods: We evaluated 208 patients with a SL/Bicon-Plus primary THA (218 hips). Survival analysis was performed with a follow-up of 13 to 15 years.

Long-term outcomes of patellofemoral arthroplasty.

The purpose of this study was to correlate the long-term survival of patellofemoral arthroplasty with primary diagnosis, age, sex, and body mass index. One hundred eighty-five consecutive Richards type II patellofemoral arthroplasties were performed in 161 patients with isolated patellofemoral osteoarthritis. Diagnoses included primary patellofemoral osteoarthritis, posttraumatic patellofemoral osteoarthritis, and patellofemoral osteoarthritis with a previous realignment procedure for patellar subluxation or trochlear dysplasia.

[Fewer blood transfusions after introduction of auto-transfusion system as part of hip- and knee-replacement surgery].

Objective: To establish the effect of the introduction of an auto-transfusion system on the number of homologous blood transfusions required as part of total hip- and knee-replacement surgery.

Design: Prospective observational study.

Methods: The number of homologous blood transfusions required after total hip or knee replacement was compared between a group of 195 patients before and a group of 176 patients after introduction of an auto-transfusion system.
