INTRODUCTION: To assess whether patient satisfaction with their hospital stay influences the early outcome of total knee arthroplasty (TKA). METHODS: During a 5-year period patients undergoing primary TKA at the study centre had prospective outcome data recorded (n = 2264). The Oxford knee score (OKS) and the short form (SF)-12 were recorded pre-operatively and 1 year post-operatively when satisfaction with their TKA was also assessed. Patient satisfaction with their hospital stay was also evaluated and their reasons for it were qualitatively documented...

Total knee arthroplasty (TKA) has become one of the most common orthopedic surgical procedures performed nationally. As the population and surgical techniques for TKAs have evolved over time, so have the anesthesia and analgesia used for these procedures. General anesthesia has been the dominant form of anesthesia utilized for TKA in the past, but regional anesthetic techniques are on the rise. Multiple studies have shown the potential for regional anesthesia to improve patient outcomes, such as a decrease in intraoperative blood loss, length of stay, and patient mortality...

PURPOSE: The aim of this study was to investigate the results of total knee arthroplasty (TKA) performed after varus distal femoral osteotomy (VrDFO), in comparison to a control group of TKAs performed as the primary intervention for arthrosis. Main hypothesis was that the medium term results for the two groups would be similar. METHODS: All TKAs performed after VrDFO were extracted from a single centre, prospective database of 4046 arthroplasties. A case-control study was performed with a control group comprising two TKAs performed as the primary intervention for each TKA after VrDFO, and matched for sex, age at intervention, body mass index, the type of arthrosis and the type of implant...

BACKGROUND: Total Knee Arthroplasty (TKA) is a common and generally effective procedure performed mainly due to advanced osteoarthritis, pain, physical disability and reduced quality of life. However, approximately 20% of the patients respond poorly to the surgery and chronic pain and disability following TKA remains a major health burden for many patients. Among the most well documented and powerful psychological predictors of poor outcome following TKA is pain catastrophizing. Recent research has shown that patients with these thoughts are at higher risk of having persistent pain and lower physical function after the operation than patients with low levels of pain catastrophizing before TKA...

The purpose of this article is to review the etiology, economic burden, treatment strategies, and future research directions of arthrofibrosis after total knee arthroplasty (TKA). Arthrofibrosis is a debilitating postoperative complication of TKA. This condition is one of the leading causes of hospital readmission and a predominant reason for TKA failure. The prevalence of arthrofibrosis will increase as the annual incidence of TKA in the United States rises into the millions. Characterized by the excessive proliferation of scar tissue during an impaired wound healing response, the resulting stiffness of arthrofibrosis causes functional deficits in activities of daily living, such as walking, stair climbing, and standing from a chair...

Same-stage tibial osteotomy may deserve consideration in candidates to total knee arthroplasty (TKA) who have severe bone deformities, particularly at extra-articular sites. This strategy obviates the need for either a major and technically difficult ligament release procedure, which may compromise ligament balancing, or the use of a semi-constrained prosthesis. This technical note describes a one-stage, computer-assisted technique consisting in TKA followed by corrective tibial osteotomy to obtain an overall mechanical axis close to 180° without extensive ligament balancing...

BACKGROUND: In contemporary total hip arthroplasties (THAs) and total knee arthroplasties (TKAs), intravenous tranexamic acid (IV TXA) has proved efficacious in decreasing blood loss and transfusion. Interested in expanding the use of IV TXA to patients with a prior venous thromboembolic event (VTE), we sought out to determine the risk of recurrent VTE with TXA administration during primary THA and TKA. METHODS: We retrospectively reviewed 1262 patients (1620 cases) with a history of VTE who underwent primary THA or TKA between 2000 and 2012...

BACKGROUND: A standing anteroposterior (AP) radiograph is commonly used to evaluate coronal alignment following total knee arthroplasty (TKA). The impact of coronal alignment on TKA outcomes is controversial, perhaps due to variability in imaging and/or measurement technique. We sought to quantify the effect of image rotation and tibial slope on coronal alignment. METHODS: Using a standard extramedullary tibial alignment guide, 3 cadaver legs were cut to accept a tibial tray at 0°, 3°, and 7° of slope...
