Patellar Malalignment / Instability
Conditions
1. Acute Patella dislocation
2. Recurrent Patellar dislocation/ subluxation
3. Anterior Knee Pain

Patellofemoral syndrome (PFS) is characterized by a group of symptoms that are easily diagnosed and often respond to simple management. The common presentation is knee pain in association with positions of the knee that result in increased or misdirected mechanical forces between the kneecap and femur. Ironically, as simple as...

Plica syndrome of the knee is a constellation of signs and symptoms that occur secondary to injury or overuse. An otherwise normal structure, a plica can be a significant source of anterior knee pain. Once an inflammatory process is established, the normal plical tissue may hypertrophy into a truly pathological...
