OBJECTIVE To determine if baseline 3-dimensional (3-D) biomechanical gait patterns differed between those patients with moderate knee osteoarthritis (OA) who progressed to total knee arthroplasty (TKA) and those that did not, and whether these differences had predictive value. METHODS Fifty-four patients with knee OA had ground reaction forces and segment motions collected during gait. 3-D hi...
BACKGROUND Inconsistent findings of weight change following total knee (TKA) and hip (THA) arthroplasty may largely be attributable to heterogeneous cohorts and varied definitions of weight loss. This study examined weight change following TKA and THA for osteoarthritis (OA). METHODS 64 participants with hip or knee OA were recruited from orthopaedic joint arthroplasty waiting lists at a sing...
Our study aimed at developing clinical thresholds (cut-off scores) for the Western Ontario and McMaster Universities (WOMAC) osteoarthritis index, EQ-5D and Knee Society Score for discriminating between patients with and without treatment success following total knee arthroplasty (TKA). We performed a retrospective analysis of 1055 patients 2 months after TKA and 765 patients 1 year after TKA. ...
OBJECTIVE There is little information on longitudinal trends in the epidemiology of total knee arthroplasty (TKA). This study was undertaken to determine whether, during the past decade, TKA rates increased in younger adults and older adults, whether utilization of TKA increased among minorities, and whether more patients underwent surgery at high-volume hospitals. METHODS TKA cases (n = 443,...
AIMS To compare the gait of unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA) patients with healthy controls, using a machine-learning approach. PATIENTS AND METHODS 145 participants (121 healthy controls, 12 patients with cruciate-retaining TKA, and 12 with mobile-bearing medial UKA) were recruited. The TKA and UKA patients were a minimum of 12 months post-operative,...
Periprosthetic fractures after total knee arthroplasty (TKA) are gradually increasing, reflecting extended lifespan, osteoporosis, and the increasing proportion of the elderly during the past decade. Supracondylar periprosthetic femoral fracture is a potential complication after TKA. Generally, open reduction and internal fixation are the conventional option for periprosthetic fracture after TK...
Background/Purpose: The purpose of this study was to determine the short-term minimal clinically important differences (MCIDs) in Knee injury and Osteoarthritis Outcome Score (KOOS) after total knee arthroplasty (TKA) using anchor method. Methods: Scores for each KOOS subscale were calculated preoperatively 3 6 months postoperatively create receiver operating characteristic curves, MCIDs calcul...
BACKGROUND The number of revision Total Knee Arthroplasty (TKA) is rising in many countries. The aim of this study was the prospective assessment of the underlying causes leading to revision TKA in a tertiary care hospital and the comparison of those reasons with previously published data. METHODS In this study patients who had revision TKA between 2010 and 2015 were prospectively included. R...
Total knee arthroplasty (TKA) continues to be very effective in providing pain relief and improved function since the early 1970s when Insall and Coventry introduced the total condylar prosthesis. In this timeframe, the number of primary total knee replacements performed in the United States outside from Federal Hospitals reached 719,000 in 2010 [1]. If the number of TKA performed continues to ...
BACKGROUND AND PURPOSE The relationship of D-dimer and deep-vein thrombosis (DVT) after total knee arthroplasty (TKA) remains controversial. The purpose of this study was to assess the value of D-dimer in the detection of early DVT after TKA. METHODS The measurements of plasma D-dimer level were obtained preoperatively and at day 7 postoperatively in 78 patients undergoing TKA. Ascending veno...
