MeshID =Patellar tendinitis (patellar tendinopathy, also known as jumper's knee), is a relatively common cause of pain in the inferior
patella r region in athletes.Presentation
It begins as inflammation in the
patellar tendon where it attaches to thepatella and may progress by tearing or degenerating thetendon . Patients present with an ache over the patella tendon.Causes
It is an overuse injury from repetitive overloading of the extensor mechansism of the
knee . The microtears exceed the body's healing mechanism unless the activity is stopped.The injury occurs in many athletes, but is most common in sports such as Football,
Soccer ,Volleyball ,Track & Field ,Freerunning ,Parkour ,American Football ,Netball ,Basketball orBadminton which require explosive movements.Treatment
Early stages may be treated conservatively. Uncommonly it may require surgery to remove
myxoid degeneration in the tendon. This is reserved for patients with debilitating pain for 6-12 months despite conservative measures.References
