Sometimes cracking and creaking sounds come from the knee. What are the reasons for this?
Crackling
To answer this question, the German Joint Center said that the knee is the largest joint in the body, and it has a complex structure. It connects the thigh to the leg, allowing slight bending, extension and rotational movements. The kneecap slides over a groove. If the quadriceps are very weak, the kneecap may slip briefly, resulting in the usual cracking sound.
The cracking sound from the knee is also due to leg deformities such as O- or X-shaped legs or temporary muscle weakness after surgery. !
Squeak
The creaking sound coming from the knee is often caused by damage to the layer of cartilage behind the kneecap, for example due to deformities, excessive stress, sports, injuries, or age-related wear and tear on the joints. !
The creaking sound may also be a sign of the beginning of what is known as osteoarthritis, which occurs due to the erosion of cartilage, the release of bone particles, and increased joint damage.
Consult a doctor
If one or more of the following symptoms appear, you should consult a doctor as soon as possible:
– Persistent or increasing pain.
– Swelling or movement restrictions.
– Poor steadiness and stability while walking or standing.
– Noticeable friction or blockage in the joint.
If treatment is neglected, these problems may lead to osteoarthritis of the knee, which not only limits movement, but may also lead to permanent damage to the joint over time.
Treatment methods
The center pointed out that not all knee problems require immediate surgery, especially in the early stages. Symptoms can often be significantly alleviated through specific measures. Building the muscles around the knee, especially the quadriceps, stabilizes the patella and improves its movement. Physical therapy exercises are also useful.
In addition, individually fitted insoles or orthotics help better guide the patella and prevent incorrect loading.
Overweight people can significantly reduce the stress on the knee joint by losing weight.
Surgery is only necessary in the advanced stage of osteoarthritis, as well as if there is structural damage to the joint.
