BACKGROUND The number of revision total knee arthroplasties (TKAs) in Asian countries is projected to increase with the rapid growth of primary TKA. We investigated the factors associated with the incidence of revision TKA using a nationally representative database. METHODS Data collected by the Health Insurance Review Agency of Korea, from 260,068 TKA patients between 2007 and 2012, were use...

There has been an increase in the prevalence of morbid obesity and the demand for total knee arthroplasty (TKA). Physicians must help patients with bilateral knee arthritis to make informed decisions regarding whether to undergo staged, sequential, or simultaneous TKA. The purpose of this study was to evaluate the perioperative complications of 2-team simultaneous bilateral TKA in the morbidly ...

Abstract Introduction We determined the association between frailty and 30-day mortality following total hip knee arthroplasty (THA/TKA) due to osteoarthritis also impact of THA/TKA on compared a control population. Method used linked primary secondary care data Office for National Statistics data. Frailty was assessed using electronic index categorised as fit, mild, moderate, severe frailty. T...

OBJECTIVES Outcomes in total hip and knee arthroplasty (THA and TKA), such as allogeneic transfusions or extended length of stay (LoS), can be used to compare the performance of hospitals. However, there is much variation in these outcomes. This study aims to rank hospitals and to assess hospital differences of two outcomes in THA and TKA: allogeneic transfusions and extended LoS, and to additi...

Background and purpose - There is no consensus about the outcome of simultaneous vs. staged bilateral total knee arthroplasty (TKA). We examined this issue by analyzing 238,373 patients. Patients and methods - Demographic, clinical, and outcome data were evaluated for TKA patients (unilateral: 206,771; simultaneous bilateral: 6,349; staged bilateral: 25,253) from the Canadian Hospital Morbidity...

Abstract Objectives Approximately 20% of knee osteoarthritis patients undergoing total arthroplasty (TKA) report chronic postoperative pain. Studies suggest that preoperative variables such as impaired descending pain control, catastrophizing, function, and neuropathic pain–like symptoms may predict 12 months after TKA, but the combined prediction value these factors has not been tested. The cu...

Background: Rotating-hinge knee (RHK) implants are an option for arthroplasty in cases of instability or severe bone loss. However, the revision rate can be increased compared to unconstrained which mandate improvements implant design. This study investigates a novel RHK design total (TKA). Methods: Retrospective analysis single TKA (GenuX MK, Implantcast) implanted between 2015 and 2019 includ...

AIM To compare infection rates in primary and revision total knee arthroplasty (TKA) procedures using antibiotic impregnated bone cement (AIBC) to those rates in procedures not using AIBC. METHODS A systematic review and meta-analysis was conducted in search for randomized controlled trials/studies (RCTs) pertaining to the field of antibiotic AIBC vs non-AIBC groups in both primary and revisi...

Although heterotopic ossification (HO) after total hip arthroplasty has been very well described as a cause of disability, much less was written on clinical dysfunction of HO after total knee arthroplasty (TKA). To the extent of our knowledge, there has been no published case of complete bony ankylosis, secondary to severe generalized HO, after a TKA. We present the case of a 67-year-old female...

The surgical goal of primary total knee arthroplasty (TKA) is to provide a well-balanced soft-tissue envelope surrounding a well-aligned, well-fixed implant. Some knee surgeons have emphasized that a good outcome in primary TKA is more dependent on soft-tissue management than bone management. Thus, it is imperative that the surgeon is familiar with knee soft-tissue balancing techniques to addre...
