However, it remains uncertain whether increasing the applied quadriceps muscle load would have resulted in increased contact pressures in the patellofemoral joint
, as Eilerman et al.
It has been recognized that motion of the tibia and femur in the transverse and frontal planes may have an effect on the patellofemoral joint
An MRI with this technique certainly helps one evaluate the articular surface of the patellofemoral joint
Effect of bracing on patellofemoral joint
stres while ascending and descending stairs.

kinematics in individuals with and without patellofemoral pain syndrome.
Addressing abnormal patellofemoral joint
stresses, which are thought to be due to lateral tracking of the patella, is usually an integral part of any treatment strategy, with methods such as patella taping and quadriceps strengthening typically used.
Introduction: A commonly cited theory states that patellofemoral pain is the result of elevated patellofemoral joint
reaction forces (PFJRF's) that contribute to excessive joint stress and cartilage pathology.
Research shows traditional non-impact cardio machines can cause patellofemoral joint
stress at levels equivalent to squats, stair climbing and lunges
The patella is constrained in the patellofemoral joint
during the flexion cycle by a complex interplay between bony restraints and other primary stabilizers (ligamentous and bony anatomy of the knee), secondary stabilizers (such as the quadriceps musculature), position of the tibial tubercle, and the overall coronal and rotational alignment of the lower extremity.
The majority of these involve the patellofemoral joint
Specifically, strong quadriceps muscles protected the patellofemoral joint
from cartilage loss and did not worsen its loss in the tibiofemoral joint in both men and women.
Stress on any or all of these patellofemoral joint
structures may lead to a conscious perception of pain (Crossley, Bennell, Green, Cowan & McConnell, 2002).
