The Cost-Effectiveness Of A Midvastus Versus Standard Medial Parapatellar Surgical Approach For Total Knee Arthroplasty, Ishita Joshi
The Cost-Effectiveness Of A Midvastus Versus Standard Medial Parapatellar Surgical Approach For Total Knee Arthroplasty, Ishita Joshi
Electronic Thesis and Dissertation Repository
The minimally invasive midvastus (MMV) surgical approach for total knee arthroplasty (TKA) is a less invasive technique that has been proposed to accelerate recovery over standard TKA, however, advantages are not yet definitively established. We investigated the cost-effectiveness of MMV TKA versus the standard medial parapatellar (MPP) approach for TKA alongside a randomized controlled trial in patients with knee osteoarthritis. Patients reported resource use as well as indirect costs, and health outcomes were measured using the EQ-5D-5L and the Western Ontario and McMaster Universities Osteoarthritis Index over the 12-month study period. The results of our net benefit regression analysis suggest …

Kinematics In Total Knee Arthroplasty, Allan Roy Sekeitto
Electronic Thesis and Dissertation Repository
Total knee arthroplasty (TKA) continues to be a successful procedure for the past 50 years. We investigated the kinematics after under- and overstuffing the joint space with the polyethylene (PE) insert in both cruciate-retaining (CR) TKA and posterior-stabilized (PS) TKA. We compared CR and PS designs to evaluate their respective kinematic differences. This study employed a hybrid computational-experimental joint motion simulation on a 6 degrees of freedom joint motion simulator. Physical prototypes of a virtually performed TKA based on cadaveric CT scans and a virtual ligament model were utilized. We demonstrated understuffing decreases stability and the joint compressive forces, with …

Predicting Dissatisfaction With Total Knee Arthroplasty, Joseph S. Munn
Electronic Thesis and Dissertation Repository
Total knee arthroplasty (TKA) is a common and effective treatment for end-stage osteoarthritis. However, approximately 20% of patients are consistently found to be dissatisfied or unsure of their satisfaction with their TKA at 1-year post-surgery. Two strategies for reducing dissatisfaction have appeared in the literature. The first aims to reduce the number of dissatisfied patients who will undergo surgery by identifying patients likely to be dissatisfied pre-surgery. The second aims to implement interventions that improve patient satisfaction by generating realistic expectations for outcomes and by association improving met expectations scores. It may be possible to improve the performance of these …
