The number of elderly patients undergoing total knee arthroplasty (TKA) has steadily increased. Elderly patients undergoing TKA usually have underlying diseases, and some of them take antithrombotic agents for the prevention or treatment of these co-morbidities, including cardiovascular, cerebrovascular, or thromboembolic diseases. When these patients are scheduled to undergo TKA, preoperative ...

Aim: Total knee arthroplasty (TKA) is commonly performed to relieve pain and improve function in patients with rheumatoid arthritis (RA). However, treatment with posterior cruciate ligament–retaining (CR-type) TKA is thought to be controversial, particularly in patients with RA. In the present study, we aimed to investigate the clinical results of CR-type TKA and evaluate the efficacy of this t...

BACKGROUND Kinematically aligned total knee arthroplasty (TKA) is of increasing interest because this method might improve postoperative patient satisfaction. In kinematic alignment the femoral component is implanted in a slightly more valgus and internally rotated position, and the tibial component is implanted in a slightly more varus and internally rotated position, than in mechanical alignm...

Total knee arthroplasty (TKA) is one of the most commonly performed elective orthopaedic procedures in the United States [1]. By 2030, the number is estimated to grow by 673% to 3.48 million TKAs performed a year [1]. TKA provides significant pain relief and improvement in quality of life [2]. However TKA surgery is not without complications. Of note is the risk of bleeding and requirement for ...

BACKGROUND This study compared clinical and radiological results between robotic total knee arthroplasty (TKA) and conventional TKA with a cruciate-retaining implant at 10-year follow-up. The hypothesis was that robotic TKA would allow for more accurate leg alignment and component placement, and thus enhance clinical and radiological results and long-term survival rates. METHODS A total of 11...

Venous thromboembolism (VTE) is a potential complication occurring after total knee arthroplasty (TKA). We investigated the incidence of VTE after TKA using contrast-enhanced computed tomography (CT), and assessed the efficacy of VTE prophylaxis (fondaparinux and enoxaparin). At our hospital, 189 patients (225 knees) underwent TKA between April 2007 and October 2011. The 225 knees were divided ...

OBJECTIVE This population-based study investigated the subsequent cardiovascular risk of patients with knee osteoarthritis underwent total knee arthroplasty in Taiwan. MATERIALS AND METHODS This was a population-based follow-up study of 22931 patients diagnosed with knee osteoarthritis between 2008 and 2011. Each patient was followed for 3 years or until death. Treatment was dichotomized into...

Many patients in need of total knee arthroplasty (TKA) have bilateral symptoms and require surgery to both extremities. Performance of a bilateral procedure under a single anesthetic provides a reduced hospitalization time, an isolated anesthesia risk, a single rehabilitation, and substantial cost savings. While most current research examines postoperative complication rates, the primary purpos...

BACKGROUND knee arthritis is a risk factor for falling. Increasing numbers of people are receiving total knee arthroplasty (TKA) but the natural history of falling before and after TKA is unknown. OBJECTIVE to prospectively monitor falls in pre- and post-operative TKA patients and to identify independent risk factors for post-operative falling. DESIGN a prospective observational study with ...

INTRODUCTION Recent clinical studies have shown that computer navigation for total knee arthroplasty (TKA) provides improved component alignment accuracy, and can help to avoid femoral malrotation and errors in axial alignment [1]. However, femoral stress fracture after computernavigated TKA has been reported due to the pin hole [2] and we hypothesized that osteoporosis would be one of the key ...
