BACKGROUND Although the numbers of total knee arthroplasty (TKA) are increasing, there is only a small number of studies investigating driving safety after TKA. The parameter 'Brake Response Time (BRT)' is one of the most important criteria for driving safety and was therefore chosen for investigation.The present study was conducted to test the hypotheses that patients with right- or left-sided...

Virtual reality-based rehabilitation (VRBR) is being used in after total knee arthroplasty (TKA). This meta-analysis assesses the effect of immediate and/or maintained VRBR (alone or combination with conventional therapy (CT) TKA recovery. To perform this meta-analysis, we searched PubMed, SCOPUS, WOS, CINAHL, and PEDro until 5 February 2023. We included randomized controlled trials that assess...

BACKGROUND To characterize whether medical comorbidities, depression and anxiety predict patient-reported functional improvement after total knee arthroplasty (TKA). METHODS We analyzed the prospectively collected data from the Mayo Clinic Total Joint Registry for patients who underwent primary or revision TKA between 1993-2005. Using multivariable-adjusted logistic regression analyses, we ex...

BACKGROUND Total knee arthroplasty (TKA) is common, effective, and cost-effective. Innovative implants promising reduced long-term failure at increased cost are under continual development. We sought to define the implant cost and performance thresholds under which innovative TKA implants are cost-effective. METHODS We performed a cost-effectiveness analysis using a validated, published compu...

We propose a top-down algorithm for extracting k-best lists from a parser. Our algorithm, TKA∗ is a variant of the kbest A∗ (KA∗) algorithm of Pauls and Klein (2009). In contrast to KA∗, which performs an inside and outside pass before performing k-best extraction bottom up, TKA∗ performs only the inside pass before extracting k-best lists top down. TKA∗ maintains the same optimality and effici...

There is no known causal link between total knee arthroplasty (TKA) and pigmented villonodular synovitis (PVNS). There also is no known relationship between PVNS and implant loosening after TKA in the literature. This article presents a case of PVNS in a patient undergoing revision TKA for tibial component loosening. A 74-year-old woman who had undergone cemented bilateral TKA 5 years earlier p...

BACKGROUND Lack of evidence contributes to unnecessary variation in treatment costs and outcomes. This study aimed to identify from interventions historically used for total knee or hip arthroplasty (TKA, THA): i) if routine use is supported by high-level evidence; ii) whether surgeon use aligns with the evidence. METHODS Part 1: Systematic search of electronic library databases for systemati...

BACKGROUND Various implants of total knee arthroplasty (TKA) are used in clinical practice and each presents specific design characteristics. No implant managed this day to reproduce perfectly the biomechanics of the natural knee during gait. OBJECTIVES We therefore asked whether (1) differences in tridimensional (3D) kinematic data during gait could be observed in two different designs of TK...

BACKGROUND This study investigated the effects of total knee arthroplasty (TKA) on bone mineral density (BMD) of the proximal femur in patients who underwent the procedure. METHODS Forty-eight patients scheduled to undergo unilateral TKA because of primary knee osteoarthritis were included in this study, which was conducted at a medical center between October 2006 and October 2009. In these 4...

OBJECTIVE To discuss the surgical methods of total knee arthroplasty (TKA) in the patients with active tuberculosis of the knee and find out its curative effect after TKA. PATIENTS AND METHODS We analyzed 10 patients with active tuberculosis of the knee who received TKA in our department from March 2006 to March 2010, whose ages were from 22 to 64 years old (average age was 40.6 ± 1 years). T...
