Background: Although an increased life expectancy has been previously reported in patients with osteoarthritis (OA) after undergoing total knee arthroplasty (TKA), the long-living Japanese population may provide a more accurate cohort for determining 10- and 15-year survival rates. The aims of the present study were to (1) determine the survival of patients after TKA, (2) identify the factors important for survival, and (3) compare the survival rate of the OA patients with that of the standardized general population...

BACKGROUND: Total knee arthroplasty (TKA) is associated with a risk of thromboembolism requiring routine thromboprophylaxis, but there is debate about the risk with unicondylar knee arthroplasty (UKA) as it is a more minor procedure. We sought to investigate the relative risk of thromboembolism with UKA compared to TKA and one-staged bilateral TKA (BTKA) by measuring the increase in circulating biochemical markers of thrombin generation during the procedures. Degree of surgical trauma was also assessed by measuring interleukin-6, a marker of metabolic injury...

A 70-year-old Indian woman, who had undergone primary bilateral total knee arthroplasty (TKA) for rheumatoid arthritis 10 months prior, presented with 10 days history of pain, swelling and erythema over both knees with pus discharging from the right knee. She had type 2 diabetes mellitus and was on long-term steroid, leflunomide and antitumour necrosis factor therapy for rheumatoid arthritis. Her clinical and laboratory features were suggestive of a haematogenous periprosthetic joint infection (PJI). The final diagnosis of bilateral Salmonella typhi PJI was made based on culture reports...

Although acute ischemic stroke (AIS) is a feared medical complication after total knee arthroplasty (TKA), little is known about its incidence and risk factors. The purpose of this retrospective populationbased study using the Nationwide Inpatient Sample (2008-2011) was to determine the incidence and predictors of AIS following TKA. The rate of perioperative AIS was 0.08%. Patients undergoing bilateral TKA were almost three times more likely to develop AIS compared with unilateral TKA patients. The age group with the highest odds of AIS was ≥85 years...

Introduction: Recent studies have shown that in addition to patient factors, surgeon volume has influenced total knee arthroplasty (TKA) outcomes greatly. With recent propositions of regionalization of arthroplasties to higher volume centers, the need for further evidence is warranted. Materials and methods: Retrospective Cohort Study done at Aga Khan University Hospital, Pakistan from January 2007 to December 2015. High Volume (HV) group was set as at least 50 TKAs/year and Low Volume (LV) was set as at most 25 TKAs/year...

BACKGROUND: Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are currently grouped under the same Diagnosis-Related Group (DRG). With the introduction of bundled payments, providers are accountable for all the costs incurred during the episode of care, including the costs of readmissions and management of complications. However, it is unclear whether readmission rates and short-term complications are similar in primary THA and TKA. METHODS: The National Surgical Quality Improvement Project database was queried from 2011 to 2015 to identify 248,150 primary THA/TKA procedures using Current Procedural Terminology codes...

BACKGROUND: Simultaneous bilateral total knee arthroplasty (SBTKA) offers significant socioeconomic benefits. However, retrospective studies and public health data show increased mortality and morbidity rates in patients undergoing SBTKA compared with those undergoing unilateral TKA (UTKA), and there have been recommendations against the use of SBTKA. High-volume centers, which feature careful patient selection and fast-tracked surgery, continue to perform SBTKA and have published their results in favor of the procedure...

BACKGROUND: Internal rotation of the hip and lateral patellar tilt increases after total hip arthroplasty (THA). However, it remains unknown whether these parameters change with time after the index THA. METHODS: A total of 91 patients undergoing 2-stage bilateral primary THAs between January 2008 and May 2014 were included to assess the association of chronological changes in internal rotation of the hip or lateral patellar tilt with anthropometric and perioperative parameter and changes in alignment after the index THA...

PURPOSE: It is well known that total knee replacement surgery decreases pain and improves function, but the effect on postural assessment needs to be studied better with the use of new technological devices. Total knee arthroplasty (TKA) improves motor coordination and stability of the knee. On the other hand, changing joint functionality can modify the balance. The aim of this trial is to record and analyze the static and dynamic baropodometric data of patients in the first few months following joint replacement...

BACKGROUND: Factor-Xa inhibitors have been introduced for prevention of venous thromboembolism (VTE) after joint arthroplasty. However, these agents could also be associated with bleeding or wound complications after surgery. METHODS: We retrospectively reviewed a consecutive series of 59 patients (31 knees, 28 hips) undergoing joint arthroplasty at a high-volume joint arthroplasty referral center, both before and after implementation of a new VTE risk-stratification tool at our institution...

AIMS: The length of the tourniquet time during total knee arthroplasty (TKA) is related to the incidence of post-operative deep vein thrombosis (DVT). Our aim in this study was to investigate the effect of the early release of the tourniquet on the incidence of DVT in patients undergoing TKA. METHODS: A total of 200 patients who underwent TKA between November 2015 and November 2016 were prospectively enrolled. The tourniquet was inflated before surgery and released immediately after the introduction of the components (early release group)...

BACKGROUND: Knee osteoarthritis is a highly prevalent degenerative joint disorder characterized by joint tissue damage and pain. Knee joint distraction has been introduced as a joint preserving surgical procedure to postpone knee arthroplasty. An often used standard externally fixation device for distraction poses a burden to patients due to the absence of joint flexion during the 6weeks treatment. Therefore, a personalized articulating distraction device was developed. The aim of this study was to test technical feasibility of this device...
