What is Jumper's Knee?
Jumper’s knee is a condition of the knee, formally known as patellar tendinopathy. It is a painful condition, most often related to activities involving repeated and forceful knee flexion and extension, such as jumping as the name implies. While the cause of patellar tendinopathy is multi-faceted, it is generally known as a sport-related “overuse” or maladaptive training injury causing localized microtearing and inflammation of the patellar tendon, and is most common in sports which require high power output and high eccentric loading on the quadriceps muscles such as track and field, basketball, skiing, and volleyball. It is a clinical diagnosis and does not require expensive imaging in order to determine, although ultrasound may be useful in some cases.
