Aims

The aim of this study was to characterize the factors leading to transfemoral amputation after total knee arthroplasty (TKA), as well as the rates of mortality and functional independence after this procedure in these patients.

Patients and Methods

This was a multicentre retrospective review with a prospective telephone survey for the assessment of function. All patients with a TKA who subsequently required transfemoral amputation between January 2001 and December 2015 were included. Demographic information, medical comorbidities, and postoperative mortality data were collected. A 19-item survey was used for the assessment of function in surviving patients.

Introduction

Recovery after total knee arthroplasty (TKA) may take longer than patients expect. Furthermore, there are a subset of patients who still experience pain and dissatisfaction despite normal physical examination, radiographs, and laboratory analysis. Corticosteroid injection (CSI) is commonly used nonsurgical treatment for painful knee arthritis. However, the efficacy of CSI in patients with a painful TKA remains unknown.

Methods

A retrospective charge review was performed to identify a cohort of patients who had a primary TKA performed between 2015 and 2016 and later received a CSI. All TKAs and CSIs were performed by a fellowship-trained arthroplasty surgeon. Patients receiving a CSI underwent a clinical exam, laboratory analysis to rule out infection, and radiographic evaluation prior to injection. Patient variables were recorded and a survey assessed the efficacy of the injection. The survey response rate was 63.6%.

Introduction

Total Knee Arthroplasty (TKA) in high risk patients may result in numerous post-operative complications that may ultimately lead to above knee amputation (AKA). There is a paucity of literature regarding AKA in patients with prior TKA. We sought to characterize the factors leading to AKA, as well as patient functional and clinical outcomes post-operatively, with the hypothesis that minimal activity would be achieved.

Methods

This is a multicenter retrospective review for patient identification, with prospective telephone survey completion for assessment of functional status. All patients from January 2001 to December 2015 with AKA and prior TKA at two academic centers were included for possible survey enrollment. Demographic information and medical comorbidities were collected, in addition to perioperative and post-operative mortality data. A 23-item survey was provided to all available patients and analyzed for patient functional status.
