What Is Jumper’s Knee?
Most common in athletes who perform activities involving a lot of jumps or kicks, jumper’s knee is an overload injury that can affect non-athletes, too. At the root is a large tendon running across your kneecap from the thigh muscle (the quadriceps) and connecting the kneecap to your shinbone.
It is this tendon (the kneecap tendon, or ligamentum patellae) that becomes irritated and damaged when you suffer from jumper’s knee. If the injury progresses over several weeks, it may become tendinopathy.
