Patellar Tendinopathy? Flashcards
What is Patellar Tendinopathy?
Patellar tendinopathy (or “jumper’s knee”) is a condition where the patellar tendon, which connects the kneecap (patella) to the shinbone (tibia), becomes irritated and painful. It commonly occurs with repetitive stress on the tendon, especially in activities like jumping or running.
What Causes Patellar Tendinopathy?
Patellar tendinopathy is often caused by repetitive loading on the patellar tendon, leading to small tears and inflammation. High-impact sports (e.g., basketball, volleyball, running), sudden increases in activity, and poor lower limb mechanics are common contributing factors.
Anatomy of the Patellar Tendon
The patellar tendon connects the kneecap (patella) to the shinbone (tibia). It works closely with the quadriceps muscle, which straightens the knee and is essential in activities like jumping, running, and squatting.
Why is the Patellar Tendon Prone to Tendinopathy?
The patellar tendon experiences high levels of stress, especially in jumping and landing. Its role in absorbing and generating force makes it vulnerable to overuse injuries, particularly in athletes.
Why Patellar Tendinopathy Happens
Patellar tendinopathy happens when the tendon is overloaded without enough time to repair. Over time, small tears develop, and the tendon weakens, causing pain. The key to healing is gradually rebuilding strength while avoiding further overload.
Avoid Aggravating Movements
Avoid activities that put a lot of strain on the patellar tendon, like deep squats, jumping, or running on hard surfaces, especially in the early stages. These can increase stress and worsen symptoms.
Early-Stage Exercises for Patellar Tendinopathy
- Isometric Leg Extensions (Early-Stage)
- Wall Sits (Early-Stage)
- Straight Leg Raises
- Partial Squats (Only if Pain-Free)
Tests
