Biomechanical Analysis Of Ligament Modelling Techniques And Femoral Component Malrotation Following Tka, Liam A. Montgomery

Electronic Thesis and Dissertation Repository

Previous studies have demonstrated that satisfaction and revision rates following total knee arthroplasty (TKA) are lower than those of comparable surgeries such as total hip replacements. A leading cause for these revisions is joint instability which may be due to improper ligament balancing or poorly aligned surgical implants. One of the methods used to investigate biomechanical forces and kinematics is computational modelling of the post-operative TKA knee.

A unique knee model was used to investigate the biomechanical and kinematic effects of ligament model complexity, as well as the effects of simulating ligament wrapping versus ignoring ligament wrapping. We then used …

Determination Of The Functional Relationship Between Lumbar Lordosis And Pelvic Tilt, Casey Tyler Hebert

Theses and Dissertations (ETD)

Americans are undergoing spinal fusion surgery (SFS) at an ever increasing rate; in 2008 over 400,000 Americans underwent SFS with a national cost of approximately $33.9 billion. During SFS it is difficult for the surgeon to properly align the spine’s s-shape, as viewed from the patient’s side. Abnormal alignment of the spine then alters the position of the pelvis and hip joints, which may impact the function and hip contact patterns. Several studies have shown that patients with spinal pathology, such as arthritis, often have a coexisting hip pathology or subsequently develop hip pathology, and it is estimated that 18% …
