Knee clicking when squatting may be due to physiological reasons, osteoarthritis, meniscus injuries and other reasons.
1. Physiological reasons: when the position of the knee joint changes suddenly, such as sudden squatting, sudden standing up, etc., it will cause the gas in the joint cavity to vibrate and make a clicking sound, which is a normal physiological phenomenon.
2. Osteoarthritis: with age, degenerative joint lesions, degenerative damage to the articular cartilage, which will cause uneven joints, in the knee squatting, due to mutual friction and clicking.
3. Meniscus injury: meniscus between the femoral condyle and tibial platform, like a cartilage pad, can protect the two joint surfaces, can play the role of absorbing shock, play the role of buffer joint pressure. When the meniscus is damaged, when squatting, due to mutual friction will also appear clicking.
Knee squatting click sound, if accompanied by pain or joint activity is limited, should go to the hospital in time, under the guidance of the doctor standardized treatment.
