Common causes of knee cracking
The article discusses the common causes of knee cracking and how to assess whether it indicates a health problem or not. It explains that these sounds are often the result of natural joint movement when flexing and extending the knee, caused by changes in the pressure of the joint fluid or the movement of the kneecap within the groove of the femur. Among other main causes are: patellofemoral pain syndrome, osteoarthritis resulting from cartilage wear, and joint hypermobility due to ligament laxity. The article emphasizes that most cases do not require treatment if there is no pain or swelling, but it is advised to see a doctor if symptoms such as pain, swelling, instability, or difficulty moving the joint appear.
