Knee

What It Is

Line drawing of the knee from the front and the side, showing the kneecap with the quadriceps tendon above it and the patellar tendon running down from its lower edge to the shin bone.
The patellar tendon runs from the bottom of the kneecap to the shin — the same small area where the bursae sit, which is why the first job is working out which one is sore.

Patellar tendinopathy (often called "jumper's knee") is an overuse injury of the patellar tendon, the tendon at the front of your knee just below the kneecap (Oxford University Hospitals NHS Foundation Trust, 2019). The patellar tendon connects the kneecap (patella) to the shin bone (tibia). It can cause pain, stiffness and sometimes mild swelling. It can take months for tendinopathy and its pain to settle completely (Oxford University Hospitals NHS Foundation Trust, 2019).

Tendinopathy happens when a tendon is unable to adapt to the level of strain placed on it. Over time, this leads to tiny changes in the tendon fibres, and as the tendon tries to heal, the fibres can become disorganised and painful (Oxford University Hospitals NHS Foundation Trust, 2019; Royal United Hospitals Bath NHS Foundation Trust, 2021). It is often caused by a sudden change in activity, such as (Royal United Hospitals Bath NHS Foundation Trust, 2021):

Lots of jumping
Lots of squatting, especially with weights
Too much hill running
Increasing running distance or speed too quickly
Increasing the intensity of sport too quickly

The condition is more common in sports that involve jumping and running, such as basketball, volleyball, football, tennis and badminton (Oxford University Hospitals NHS Foundation Trust, 2019; Schwartz, Watson and Hutchinson, 2015).

The main symptom is pain, felt just below the kneecap. Sometimes there is some mild swelling too. People notice pain on squatting, jumping and running. Many people also notice stiffness in the tendon in the morning or after sitting or driving for a long time (Royal United Hospitals Bath NHS Foundation Trust, 2021).

Patellar Tendinopathy Anatomy

The quadriceps are the main bulky muscle group at the front of the thigh. They come down the leg from the hip and attach into the patella. Below the patella, the attachment continues as the patellar tendon (in some texts known as the ligamentum patellae). It is a very thick, strong and fibrous band of tissue. However, if it is placed under repeated strain that it cannot adapt to (very often from sport), the tendon undergoes changes in its structure. Research shows these are mainly degenerative (wear-type) changes with very little inflammation (Breda et al., 2021).
