Patellar Tendonitis (Jumper’s Knee)

Patellar Tendonitis is also commonly referred to as “Jumper’s Knee.” Jumper’s Knee is pain around the patella or knee cap, often described as a dull ache deep in the front of the knee. Under the kneecap is a layer of cartilage which acts as a natural shock absorber. Injury, overuse, and aging can cause damage to that cartilage, resulting in pain and reduced mobility. Pain is often made worse when sitting with knees bent for a long time, squatting or kneeling, or when walking up and down stairs.

The patellar tendon connects the quadriceps muscle to patella and then the patella to the tibia or shin bone. Contraction of the quadriceps muscle causes the lower leg to extend through the patella tendon.

Activities involving kicking, jumping, or explosive movements rely on quick and forceful contraction of the quadriceps muscle for power. These activities are most common in sports involving jumping. However, patellar tendonitis can occur in any activity that involves contraction of the quadriceps, including running, biking, skiing, or climbing.



Jumper’s Knee pain may decrease with rest and ice, but sometimes that simply isn’t enough. One of the most effective treatments for Jumper’s Knee is Active Release Technique (ART®). This, in combination with specific resistance exercises and chiropractic adjustments, can help restore full strength.
