Recurrent patellar instability can result from osseous abnormalities, such as patella alta, a
distance of> 20 mm between the tibial tubercle and the trochlear groove, and trochlear …

This review describes anatomic features of the patellofemoral joint that relate to the stability
and function of the joint. The role of the geometry of the articular surfaces, particularly the …

The patellofemoral joint is a joint that can be an area of concern for athletes of various sports
and ages. The joint is somewhat complex with multiple contact points and numerous tissues …

Normal function of the patellofemoral joint is maintained by a complex interaction between
soft tissues and articular surfaces. No quantitative data have been found on the relative …

This was a quantitative study of the major anatomical structures associated with instability of
the patellofemoral joint: the quadriceps muscles and the femoral trochlear groove. The …

Purpose: The purpose of this study was to evaluate the effect of surgical reinsertion of the
medial patellofemoral ligament (MPFL) to the adductor tubercle compared with conservative …

The patella is the largest sesamoid bone in the body. The patellofemoral joint provides an
integral articulating component of the extensor mechanism of the knee joint. A detailed …

Patellar tracking is defined as the motion of the patella relative to the femur or femoral
groove on knee flexion and extension. Abnormalities of tracking (maltracking) are thought to …

Purpose The influence of the medial patellar ligamentous structures on patellar tracking has
rarely been studied. Thus the main purpose of this cadaveric biomechanical study was to …

A common rehabilitation strategy for patellofemoral pain syndrome (PFPS), which lacks
scientific evidence, includes pulling the patella medially with tape to reduce pain and …
