BACKGROUND Patients undergoing total hip or knee arthroplasty frequently receive blood transfusions. The relationship between transfusion and the risk of infection following total joint arthroplasty is unclear. In this study, we sought to examine the impact of allogeneic and autologous transfusion on the risk of acute infection following total hip and total(More)
With improvements in surgical techniques, implant design, and patient caremaps, surgeons have sought to accelerate early rehabilitation after total hip arthroplasty. Many authors have reported results of fundamentally similar protocols to achieve this end. These protocols focus on multi-modal pain management, early therapy, tissue-preserving surgical(More)
Management of symptomatic pre-collapse osteonecrosis of the femoral head continues to be controversial. Patients are often young and active, therefore hip-preserving procedures such as free vascularized fibular grafting (FVFG) have been developed to relieve pain and restore function, thereby delaying or preventing the need for joint arthroplasty. This study(More)
Clinical outcomes were retrospectively reviewed for 76 primary total hip (THA) and total knee arthroplasties (TKA) performed after kidney, liver, cardiac, and lung transplantation with follow-up of 30.2 and 41.2 months, respectively. For the THA and TKA cohorts, there were a high rate of medical complications (29% and 33%), increased hospital length of stay(More)
Total hip and knee arthroplasties are two of the most successful orthopaedic procedures. However, with the increasing demand, estimated future costs for these procedures are enormous. Recent data suggest post-discharge care may account for up to 35% of total episode payments. Yet, little is known about targets that can help improve quality and reduce cost.(More)
BACKGROUND Unicompartmental knee arthroplasty is a less-invasive alternative to total knee arthroplasty for patients with arthritis affecting only the medial or lateral compartment. However, little is known about recent trends in the use of these procedures and the associated outcomes among older patients. METHODS With use of a nationally representative(More)
Simultaneous bilateral total knee arthroplasty (TKA) reportedly has higher postoperative complication rates than staged procedures, but little is known about recent trends and outcomes among Medicare patients. In a 5% national sample of Medicare beneficiaries older than 65 years, we identified 83,441 patients who underwent elective TKA between 2000 and 2009(More)
BACKGROUND Dexamethasone is frequently used for the treatment of postoperative nausea and vomiting and as an adjunct in multimodal postoperative analgesia after total joint arthroplasty; however, the incidence of periprosthetic joint infection (PJI) after the use of perioperative dexamethasone in total joint arthroplasty has yet to be fully elucidated.

BACKGROUND Obesity has an important impact on the future of total joint arthroplasty; however, the definition and influence of obesity on surgical risks and outcomes remain controversial. Our hypothesis was that percent body fat was better than body mass index (BMI) at identifying clinical risks and patient-reported functional outcomes following(More)
