Patellar Tendinopathy
What is it? Patellar tendinopathy is degenerative process of the patellar tendon, usually where it inserts on the inferior pole of the patella.
How does it present? This often presents with pain in the area of the patellar tendon after or during activities that load the patellofemoral joint, such as repetitive jumping or running. It is usually of gradual onset.
Common exam findings: On exam you may find tenderness over the patellar tendon, usually over the insertion at the inferior patella. You may also find thickening of the patellar tendon.
Tests and Treatment: Usually initial testing is not necessary. You may consider knee x-rays and may sometimes find an irregularity at the distal pole of the patella. On magnetic resonance imaging (MRI) and in some cases ultrasound, sometimes degeneration of the patellar tendon can be seen. Treatment involves attempting to reduce the aggravating activity along with a functional rehabilitation program. At times, an infrapatellar strap may be used to decrease pain, but this has not been proven to be effective.
