Is there a place for rotating-hinge arthroplasty in knee revision surgery for aseptic loosening?

We reviewed the results of 78 revision total knee arthroplasties using a rotating-hinge device, performed from 1993 through 2002. The average follow-up was 7.83 years.

Simultaneous dislocation of both joints of the thumb with a fracture involving the interphalangeal joint. A case report and a review of the literature.

Combined dislocation of the metacarpophalangeal and interphalangeal joints of the thumb is uncommon, only five cases having been previously reported. In this case report, a previously unreported case characterized by volar-ulnar dislocation of the metacarpophalangeal joint and dorsal dislocation of the interphalangeal joint, associated with a unicondilar open fracture of the proximal phalanx, is presented. Only open reduction for the interphalangeal joint was needed and both (metacarpophalangeal and interphalangeal) joints were treated with K-wire fixation after reduction.

Stress fracture of the femoral neck as a complication of total knee arthroplasty.

Stress fracture of the hip is a rare complication of total knee arthroplasty that occurs most often in patients in whom a significant deformity of the knee has been corrected, particularly those with poor mobility before surgery. We report 4 cases of ipsilateral fracture of the femoral neck after total knee arthroplasty.

Pharmacoeconomic analysis of bemiparin and enoxaparin as prophylaxis for venous thromboembolism in total knee replacement surgery.

Introduction: Low molecular weight heparins are effective and have a good tolerability profile as first-line prophylaxis for venous thromboembolism (VTE) in major orthopaedic surgery. However, pharmacological inequivalence within the class could lead to differences in cost-effectiveness ratios.

Objective: To quantify the potential economic impact of subcutaneous bemiparin sodium 3500 IU/day compared with enoxaparin sodium 40 mg/day as prophylaxis for VTE in patients undergoing total knee replacement (TKR) surgery, considering both in-hospital and post-discharge outcomes and costs during 6 weeks of postoperative follow-up.

Efficacy and safety of bemiparin compared with enoxaparin in the prevention of venous thromboembolism after total knee arthroplasty: a randomized, double-blind clinical trial.

In this randomized, multicenter, controlled, double-blind, sequential trial, 381 patients undergoing primary total knee replacement were randomly assigned to receive subcutaneous injections of either 3500 IU anti-factor Xa of bemiparin sodium, first dose 6 h after surgery, or 40 mg of enoxaparin, first dose 12 h before surgery, followed by daily doses for 10 +/- 2 days, for the prophylaxis of venous thromboembolism. The primary efficacy endpoint was venous thromboembolism up to postoperative day 10 +/- 2, defined as deep vein thrombosis detected by mandatory bilateral venography, documented symptomatic deep vein thrombosis and/or documented symptomatic pulmonary embolism. The primary safety endpoint was major bleeding.
