BACKGROUND Total knee arthroplasty (TKA) is the most frequently performed joint replacement surgery in North America. Patient perspectives on TKA have been investigated in various ways, including finding as many as 20% of TKA patients are dissatisfied with their surgical outcomes. Understanding the patient experience with TKA broadly and in relation to patient satisfaction is a key gap in exist...

BACKGROUND Simultaneous bilateral total knee arthroplasty (TKA) is an effective treatment option and safe for properly selected patients. The purpose of this study was to evaluate whether patients have different satisfaction levels between the first and second knee in the early stage after simultaneous bilateral TKA. METHODS We retrospectively reviewed 46 patients who underwent simultaneous b...

Abstract Introduction We determined the impact of deprivation and frailty at time diagnosis hip or knee osteoarthritis (OA) on likelihood receiving total hip/knee arthroplasty (THA/TKA). Method used routinely collected primary care data (Clinical Practice Research Datalink), linked to Hospital Episode Statistics. Frailty was assessed OA using electronic index categorised as fit, mild, moderate,...

BACKGROUND We retrospectively investigated the prevalence of femoral anterior notching and risk factors after total knee arthroplasty (TKA) using an image-free navigation system. METHODS We retrospectively reviewed 148 consecutive TKAs in 130 patients beginning in July 2005. Seventy knees (62 patients) underwent conventional TKA, and 78 knees (68 patients) received navigated TKA. We investiga...

INTRODUCTION Although being debated for many years, the superiority of posterior cruciate-retaining (CR) total knee arthroplasty (TKA) and posterior-stabilized (PS) TKA remains controversial. We compare the knee scores, post-operative knee range of motion (ROM), radiological outcomes about knee kinematic and complications between CR TKA and PS TKA. METHODS Literature published up to August 20...

Background: Total knee arthroplasty (TKA) can cause excessive blood loss requiring allogenic transfusions.Tranexamic acid (TXA) has been increasingly used for lowering blood loss. The present study aimed to comparethe efficacy of intravenous (IV) and intra-articular (IA) administrations of TXA in TKA patients who receive aspirin aschemoprophylaxis and uses no drain post-operat...

BACKGROUND An enormous economic impact can be observed for infected total knee arthroplasties (TKA). The aim of the present study was to evaluate whether a cost covering treatment of infected TKA is feasible in the German DRG System. PATIENTS AND METHODS Average total treatment costs were evaluated for infected TKA and compared with a matched pair of primary TKA. Data was generated using the ...

background:  tranexamic acid (txa) has received extensive attention in management of blood loss in orthopedic surgeries. however, the ideal method of txa administration is still controversial. this study aims to determine whether intraarticular injection of txa reduces blood loss after total knee arthroplasty (tka).   methods:  through a retrospective case-control study consecutive tka patients...

INTRODUCTION Patients suffering from bilateral knee osteoarthritis often require bilateral total knee arthroplasty (TKA) to alleviate symptoms. There is controversy surrounding the approach to the surgical treatment of such patients. We asked if Asian patients undergoing staged-bilateral TKA had any difference in their short-term functional outcomes, comparing the first TKA to the second one an...

OBJECTIVE Total Knee Arthroplasty (TKA) is performed more in working-age (<65 years) patients. Until now, research in this patient population has been conducted mainly among retired (≥65 years) patients. Aim of this study was therefore to describe demographic, physical, psychological and social characteristics of working TKA patients and to subsequently compare these characteristics with retire...
