1. The function of the patella is to:
a.afford mechanical advantage to quadriceps
2. Normally the patella tracks (glides) between the femoral condyles. Both articular facets of the patella are symetrically loaded. How would a chronic valgus stress applied to the knee
possibly affect patellofemoral joint alignment?
a. lead to excessive loading of the lateral facet due to lateral tacking of the patella
b.prevent hyperextension of the knee
c.protect the knee anteriorly
d.assist in unlocking the knee after terminal extension
e.a & b
f.a & c
g. b & d
b. lead to excessive loading of the medial facet due to medial tracking of the patella
c. neither effect is likely to occur
