BACKGROUND The timing of diagnosis of invasive surgical site infection (SSI) following joint replacement surgery is an important criterion used to determine subsequent medical and surgical management. METHODS We compared time to diagnosis of invasive SSI following hip vs knee arthroplasty. SSIs were included in the analysis if they occurred within 365 days following procedures performed from ...

OBJECTIVES To test whether bisphosphonate use is related to improved implant survival after total arthroplasty of the knee or hip. DESIGN Population based retrospective cohort study. SETTING Primary care data from the United Kingdom. PARTICIPANTS All patients undergoing primary total arthroplasty of the knee (n = 18,726) or hip (n = 23,269) in 1986-2006 within the United Kingdom's General...

OBJECTIVE To evaluate the use of routinely collected electronic health data in Medicare claims to identify surgical site infections (SSIs) following hip arthroplasty, knee arthroplasty, and vascular surgery. DESIGN Retrospective cohort study. SETTING Four academic hospitals that perform prospective SSI surveillance. METHODS We developed lists of International Classification of Diseases, N...

OBJECTIVE While psychosocial factors have been associated with poorer outcomes after knee and hip arthroplasty, we hypothesized that augmented pain perception, as occurs in conditions such as fibromyalgia, may account for decreased responsiveness to primary knee and hip arthroplasty. METHODS A prospective, observational cohort study was conducted. Preoperative phenotyping was conducted using ...

PURPOSE To measure the risk of developing signs of post-thrombotic syndrome 15 to 24 months after total hip or knee arthroplasty in patients with asymptomatic deep venous thrombosis (DVT). METHODS A total of 85 total knee arthroplasty patients and 47 total hip arthroplasty patients were postoperatively screened for asymptomatic DVT using colour duplex ultrasound. RESULTS The rate of asympto...

BACKGROUND In Denmark, approximately 12,000 hip and knee arthroplasties were performed in 2006, and the hospital costs were close to US$ 110,000,000. In a randomized clinical trial, we have recently demonstrated the efficacy of accelerated perioperative care and rehabilitation intervention after hip and knee arthroplasty compared to current intervention under ideal circumstances. We do not, how...

In a series of 1304 patients (1867 knees), the results of simultaneous and staged bilateral total knee arthroplasty were compared with each other and with unilateral total knee arthroplasty. The bilateral procedures had a significantly higher rate of complications than unilateral procedures, almost entirely because of thromboembolic problems. However, this did not correspond to an increase in m...

background:    previous studies suggest total hip arthroplasty may have some benefits compared to hemi-arthroplasty for displaced intracapsular femoral neck fractures in patients more than 60 years of age. the primary research question of our study was whether in-hospital adverse events, post-operative length of stay (los) and mortality in patients 60 year of age or older differed between total...

In limbs affected by poliomyelitis, total knee arthroplasty results in satisfactory pain relief. However, the risk of failure is high, especially if the preoperative quadriceps power is low. Therefore, treating osteoarthritis in the current patient represented a challenging procedure. A 66-year-old man presented with tricompartmental osteoarthritis of both knees, with valgus deformity of 14° on...

BACKGROUND Biomechanical parameters of the hip have been suggested to have an important influence on the development of osteoarthritis. We aimed to find out whether higher stress is generated in a hip that subsequently results in earlier hip arthroplasty compared to the contralateral hip in the same subject. METHODS Standard anterior-posterior pelvic radiographs with no or subtle radiological...
