Why does pain occur at the top of the knee when squatting?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Pain at the top of the knee when squatting typically occurs when the soft tissues, tendons, and bones around the kneecap experience excess pressure or improper movement patterns during the exercise. Common causes include quadriceps tendinitis, patellofemoral pain syndrome, poor squat form, muscle imbalances, or overuse injuries. Identifying the specific cause is essential to relieving pain and preventing further damage.

Explanation

When you squat, your knee works hard to help hold your body and move with you. Sometimes, if your muscles are weak or your form isn't quite right, the top part of your knee may feel pain. This pain can come from the tissues around the kneecap (the patella) being pushed or rubbed too much when you bend your knee. The way the kneecap slides over the bones can be affected during squatting, and if it moves too easily or not enough, it may cause irritation.

In some cases, small muscles and tendons around the knee might be strained or overused, leading to inflammation and discomfort. If you're experiencing persistent knee pain during or after squatting, you can check your symptoms to better understand what might be causing your discomfort. Making sure you have good form, building strength in your leg muscles, and taking breaks when needed can help reduce this pain.
