Muscle strength analysis of hip and knee stabilizers in individuals with Patellofemoral Pain Syndrome

Fisioterapia e Pesquisa, 2014
The Patellofemoral Pain Syndrome is one of the most common disorders of the knee, characterized by pain in the frontal part of the knee, which is worsened by activities that increase compressive forces on the joint.

Effect of change in patellofemoral joint contact area by the decrease in vastus medialis muscle activation on joint stress

Acta of Bioengineering and Biomechanics, 2023
Purpose Patellofemoral pain syndrome is a common orthopedic trauma among runners. It is unclear whether patellofemoral joint stress (PFJS) is the highest (or lowest) when the knee joint flexion angle and extension moment are in combination under the condition that vastus medialis (VM) activation decreases.

Internal Rotation, Varus, and Anterior Femoral Component Malalignments Adversely Affect Patellofemoral Joint Kinematics in Patellofemoral Arthroplasty

Arthroplasty Today, 2023
Background: Patellofemoral arthroplasty (PFA) is reported to provide nearly normal PF joint kinematics but only with adequate surgical techniques. This study evaluated the effects of various femoral component settings on patellar component biomechanics ...
