Patellar tendinopathy – Definition

Tendinopathy is an injury to the tendon. It can cause pain, swelling, and limit movement. The injuries can include:

• Tendonitis — an inflammation of the tendon (Although this term is used often, most cases of tendinopathy are not associated with significant inflammation.)
• Tendinosis — microtears (tiny breaks) in the tendon tissue with no significant inflammation

Osgood-Schlatter Disease – Definition

(IT Band Syndrome; ITBFS)

Iliotibial band friction syndrome – Definition

Iliotibial band friction syndrome (ITBFS) is an overuse injury. It happens in the soft tissues in the lower thigh near the outside of the knee. The iliotibial band (ITB) is a thick band of fibrous tissue. It runs from the hip down the outside of the thigh and attaches to the tibia. The tibia is the large bone of the lower leg.
