Background: There is an information gap in literature regarding postoperative outcome of total knee arthroplasty (TKA)in patients with hardware in-situ from the previous knee surgery. The present study aims to evaluate impact of retainedhardware on short-term outcome of TKA patients.Methods: Perioperative radiographs of patients who had undergone TKA between 2007 and 2012 were reviewedand patie...

prosthetic joint infection (pji) is a serious complication of total knee arthroplasty (tka). control of infection after a failed two-stage tka is not always possible, and the resolution of infection may require an above-knee amputation (aka) or a the-knee (kf). the purpose of this review is to determine which treatment method (aka or kf) yields better function and ambulatory status for patients...

The transfusion rate in staged bilateral total knee arthroplasty (TKA) remains high despite the application of blood management techniques. potential robotic arm-assisted TKA (R-TKA) reducing surgery has not yet been investigated. Therefore, we aimed to evaluate effectiveness R-TKA on reduction compared with conventional (C-TKA) surgery. This retrospective study involved two groups patients who...

BACKGROUND Despite the alleviation of osteoarthritis (OA) symptoms that total knee arthroplasty (TKA) provides for patients with end-stage knee OA, recent studies have suggested that TKA may not increase physical activity levels. In this study, we compare the physical activity levels of patients with OA treated nonoperatively (non-TKA) with both patients who had received TKA (post-TKA) and pati...

Forty-nine patients revised from UKA to TKA and 43 from HTO to TKA were matched to 43 aseptic, both component revision TKAs (rTKA) and 97 primary TKAs. At a mean of 4.8 years, the KSS and function scores in the UKA to TKA, HTO to TKA and primary TKA cohorts were similar. Total operative times were significantly higher in the HTO to TKA and rTKA groups. LOS was shorter in the primary TKA cohort....

Objective: Postoperative knee range of motion (ROM) is among the most important factors influencing patient satisfaction after total knee arthroplasty (TKA). The purpose of this study was to clarify the time course of improvement in knee ROM up to 12 months after TKA, including intraoperative knee ROM after implantation, and to clarify a target ROM for rehabilitation after TKA. Patients and Met...

PURPOSE To compare gait parameters in women after unilateral total knee arthroplasty (TKA) versus sequential bilateral TKA to determine the need for sequential TKA. METHODS 35 women aged 60 to 74 (mean, 70) years with bilateral varus knee osteoarthritis (OA) underwent unilateral (n=23) or sequential bilateral (n=12) TKA by a single surgeon. All patients underwent unilateral TKA; 12 patients t...

OBJECTIVES The rate of total knee arthroplasty surgery (TKA) is rising in Australia despite varying impacts of TKA on physical function (PF) in population-based studies. There are potentially modifiable risk factors that could enhance PF after TKA, so we evaluated (1) the levels of PF in persons with TKA and the rest of the population, (2) potentially modifiable characteristics of those reporti...

BACKGROUND Fresh osteochondral allograft (OCA) transplantation is an effective treatment for osteochondral defects. Some patients require further surgical intervention, such as total knee arthroplasty (TKA). The effects of prior OCA transplantation on TKA outcomes are unknown. PURPOSE This study evaluated TKA failure rates after long-term follow-up and identified factors that may have contrib...
