Symptoms and Signs
Patients often describe pain as being “inside the knee cap.” The leg tends to flex even when relaxed.
To assess the knee, a clinician can perform the Patellar Apprehension Test by moving the patella back and forth while the patient flexes the knee at approximately 30 degrees.
The patient can do the patella tracking assessment by making a single leg squat and standing, or by lying on his or her back with knee extended from flexed position. A patella that slips medially on early flexion is called the J sign, and indicates imbalance between the VMO and lateral structures.

“There is one great fact, characteristic of this our nineteenth century, a fact which no party dares deny. On the one hand, there have started into life industrial and scientific forces which no epoch of former human history had ever suspected. On the other hand, there exist symptoms of decay, far surpassing the horrors recorded of the latter times of the Roman empire. In our days everything seems pregnant with its contrary.”
—Karl Marx (1818–1883)
“The whole visible universe is but a storehouse of images and signs to which the imagination will give a relative place and value; it is a sort of pasture which the imagination must digest and transform.”
—Charles Baudelaire (1821–1867)
