Dr. James Chung | Sports Performance Physical Therapist on Instagram: "Instability =/= Pain This is a TEXTBOOK example of a “J-Sign” where the patella moves laterally during knee extension. If you look closely, you’ll also see the quads work extra hard on the eccentric (rewind and pay attention to the muscle shake) There was a previous history of dislocation, but this person is able to run, though they will feel occasional “shift”. Lots of emphasis on mid-range strength, plantarflexion, and quad

Diego Barragan, MD on Instagram: "The ‘J sign’ is a clue to patellar instability! ‍⬆️➡️ As the knee extends, the patella tracks laterally in a characteristic ‘J’ pattern, often indicating issues with tracking or alignment. When the knee flexes, the patella engages with the trochlear groove and the patella jumps medially. Patellar maltracking can cause anterior knee pain and in cases of bad instability it can lead to lateral knee dislocations! . . . . . This video is for educational and informati
