Patellofemoral joint replacement is a successful treatment option for isolated patellofemoral osteoarthritis. The short and mid-term outcomes are related to malposition and unexplained pain. Whether external rotation of the femoral component in isolated patellofemoral joint replacement is required is unclear. The primary aim of this study is to determine the CT-measured femoral component rotati...

Two stage total hip arthroplasty revision surgery includes foreign material debridment, insertion of antibiotic impregnatedcement spacer, and finally, reimplantation of the prosthesis. This review has aimed to evaluate the efficacy of antibioticimpregnated cement spacers in infection control and eradication in arthroplasties.A total of 85 articles on total hip arthroplasty wer...

BACKGROUND currently, assessment of outcomes after joint replacement is predominantly centred on impairment and activity limitation (e.g. walking), with little consideration of participation restriction. METHOD structured telephone interviews about participation in leisure activities were conducted with 56 total hip replacement (THR) and 60 total knee replacement (TKR) patients before and 1 y...

Importance Medicare launched the mandatory Comprehensive Care for Joint Replacement bundled payment model in 67 urban areas for approximately 800 hospitals following its experience in the voluntary Acute Care Episodes (ACE) and Bundled Payments for Care Improvement (BPCI) demonstration projects. Little information from ACE and BPCI exists to guide hospitals in redesigning care for mandatory joi...

Selected recent advances in immunoassay are reviewed. Development has continued on new labels (beta-lactamase, pyrophosphatase, luciferases, photoproteins, pyridopyridazines, europium cryptates, metal carbonyl complexes, porphines, phosphors) and label-detection methods (e.g., chemiluminescence assays, thermometric assays, NADP(+)- and FADP-based coupled assays). Various methods have been explo...

BACKGROUND AND PURPOSE High age is associated with increased postoperative mortality, but the factors that predict mortality in older hip and knee replacement recipients are not known. METHODS Preoperative clinical and operative data on 1,998 primary total hip and knee replacements performed for osteoarthritis in patients aged ≥ 75 years in a single institution were collected from a joint rep...
