Why does knee pain occur when squatting? Three factors may cause it

In daily life, some people will have strong pain in the knees when squatting, and the cause of knee pain is also something that everyone needs to understand clearly in time. So, what is the reason for knee pain when squatting?

1. Ligament injury around the joint

The stability of the knee ligament is relatively poor when the knee is slightly flexed. If it is suddenly subjected to external force and causes valgus or inversion, it may cause damage to the medial or lateral collateral ligament. The patient will have a clear history of trauma, knee pain, swelling, ecchymosis, and limited movement.

2. Cartilage damage

It is mainly the meniscus injury of the knee joint. When the knee joint is slightly bent, if the knee is suddenly excessively rotated inward or outward (for example, when kicking a ball by bending the calf and turning around), it may cause a meniscus tear. Meniscus injury will cause obvious tearing sensation in the knee, followed by joint pain, limited movement, limping when walking, and snapping sound when the joint moves.

3. Arthritis

When the synovium of the joint is damaged due to trauma or overwork, a large amount of fluid will accumulate, increasing the pressure inside the joint, causing joint pain, swelling, tenderness, and a rubbing sound. For example, when the knee joint is actively extended to the extreme, especially when the knee extension movement is performed with a certain resistance, the pain below the patella will be aggravated. When the knee is passively flexed to the extreme, the pain will also be significantly aggravated.
