Overview
Overview
Diagnosis is made through palpation of the knee. The patient can do the patella tracking assessment by making a single leg squat and standing, or, 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.[1]
