The Effect of Knee Extension Force on Patellofemoral Tracking
نویسندگان
چکیده
Patellofemoral pain syndrome (PFPS) is one of the most common knee disorders, with pain located primarily in the lateral aspect of the patellofemoral joint. Force imbalance in the knee extensor muscles has been associated with changes in patellofemoral tracking and is suspected to cause PFPS [1]. Specifically, weakness of the vastus medialis (VM) relative to the vastus lateralis (VL) is the usual imbalance associated with PFPS. This imbalance is believed to lead to the lateral shift in patellar tracking seen in PFPS patience compared to healthy subjects.

BACKGROUND Kneeling following total knee arthroplasty can be a difficult task, impairing the activities of patients to varying degrees. Little is known about the biomechanical effects of kneeling following total knee replacement. The objective of this study was to quantify the effects of kneeling on patellofemoral joint contact areas and pressures, knee joint reaction force, and patellar kinema...

Objective: Patellofemoral pain syndrome is a common cause of anterior knee pain .This condition may arise from abnormal muscular and biomechanical factors , that alter tracking of the patella within the femoral trachlear notch , contributing to increased patellofemoral contact pressures that result in pain and dysfunction . It was suggested that there was some pathological correlation between s...
