Anticoagulant medications help to reduce the risk of thromboembolic events after total hip arthroplasty and total knee arthroplasty. Traditionally, this has been accomplished with medications, such as low-molecular-weight heparin and warfarin. However, these traditional anticoagulants possess a variety of shortcomings that leave much room for improvement. A new class of oral anticoagulants is n...

In this article, we present a 68 year-old female case admitted with complaints of a painful knee and walking difficulty with simultaneous advanced gonarthrosis and a huge osteochondroma in posterior distal femur which was adjacent to the vessel and nerve structures, who was treated with a single incision via posterior approach for tumor excision and arthroplasty. Simultaneous tumor excision and...

Numerous nonsurgical interventions have been reported to improve symptoms of knee osteoarthritis (OA) over the short term. However, longer follow-up is required to accurately characterize outcomes such as cost effectiveness and delayed arthroplasty. A total of 553 patients with symptomatic knee OA who previously underwent a single 8-week multimodal treatment program were contacted at 1 year (n ...

BACKGROUND AND PURPOSE Poor outcomes have been linked to errors in rotational alignment of total knee arthroplasty components. The aims of this study were to determine the correlation between rotational alignment and outcome, to review the success of revision for malrotated total knee arthroplasty, and to determine whether evidence-based guidelines for malrotated total knee arthroplasty can be ...

BACKGROUND Knee arthroplasty is being increasingly performed, and also more often in a younger patient population (<65 years of age). Up to 20 % of patients remain dissatisfied after knee arthroplasty, despite the apparent technical success of the operation. Recent studies suggest that the fulfilment of patients' expectations plays an important role in achieving satisfaction. Thus, addressing p...

BACKGROUND AND PURPOSE Most studies on high tibial osteotomies (HTOs) have been hospital-based and have included a limited number of patients. We evaluated the use and outcome-expressed as rate of revision to knee arthroplasty-of HTO performed in Sweden with 9 million inhabitants, 1998-2007. PATIENTS AND METHODS 3, 161 HTO procedures on patients 30 years or older (69% men) who were operated o...

Purpose. Bicompartmental knee arthroplasty (BiKA) is a favorable alternative to total knee arthroplasty for degenerative disease limited to two knee compartments. Recently developed robotic-assisted systems improved the clinical efficacy of unicompartmental knee arthroplasty by providing enhanced component positioning with dynamic ligament balancing. The purpose of this study was to evaluate th...

BACKGROUND AND PURPOSE The incidence of knee osteoarthritis will most likely increase. We analyzed historical trends in the incidence of knee arthroplasty in Sweden between 1975 and 2013, in order to be able to provide projections of future demand. PATIENTS AND METHODS We obtained information on all knee arthroplasties in Sweden in the period 1975-2013 from the Swedish Knee Arthroplasty Regis...

Medial opening wedge high tibial osteotomy is a popular treatment option for medial compartment osteoarthritis of the knee. One of the proposed advantages is easier conversion to a total knee replacement compared to lateral closing wedge osteotomies, although there are few studies to support this. We reviewed the technical considerations in 36 knees in which conversion of a medial opening wedge...

The options for treatment of the young active patient with isolated symptomatic osteoarthritis of the medial compartment and pre-existing deficiency of the anterior cruciate ligament are limited. The potential longevity of the implant and levels of activity of the patient may preclude total knee replacement, and tibial osteotomy and unicompartmental knee arthroplasty are unreliable because of t...
