Patellofemoral Syndrome, Prystyn M. Covington Feb 2019

Patellofemoral Syndrome, Prystyn M. Covington

International Journal of Exercise Science: Conference Proceedings

CLINICAL PRESENTATION & EXAM: Patellofemoral syndrome is an aching pain at the front of the knee and is common in athletes. Patellofemoral syndrome occurs due to many factors such as overuse (repetitive stress on the knee), trauma to the knee, surgery, and weak muscles. Surgery to the knee using the patellar tendon as a graft to fix the anterior cruciate ligament greatly increases the risk of pain. Many factors play a role in increasing the risk of developing patellofemoral syndrome such as sports, age, and gender. Most people who develop patellofemoral syndrome tend to be adolescents or young adults. …
