There are a number of causes, most of which are normal. However, sometimes sounds can be a sign that there may be problems with knee health, so caution is needed.
The most common cause of knee sound is the sound made when small bubbles in joint lubricants burst. In the knee joint, lubricants, a water-like component, are present and act to soften the movement of the knee, and bubbles are created during movement and bubbles burst due to pressure changes, resulting in a 'click' or 'click' sound.
There may also be a sound of ligaments or tendons in the knee rubbing over the bone when changing posture or standing up after sitting for a long time.
Heo Dong-beom, director of Yonsei Star Hospital (Orthopedic Surgeon), said "The sound from the knee can be more pronounced if fatigue builds up after activities or excessive use of the knee, but if it is not accompanied by pain, this sound is a normal phenomenon and is not a major health problem." However, if pain is accompanied by sound or sound occurs frequently, this may not be a simple phenomenon, so it is recommended to seek a specialist's diagnosis."
◇ When pain is accompanied by sound
If persistent pain occurs with the sound of , this may not be a simple fricative sound. In particular, if the pain intensifies in the inside or front of the knee when bending or standing up, it can be an early sign of cartilage damage, ligament problems, or arthritis.
In arthritis, the joint surface becomes rough as the cartilage wears out, resulting in sound and pain. In the beginning, you can hear a 'squeak' sound, but when the cartilage wears worse and reaches the level of direct collision between bones, you can actually hear a bone cracking sound every time you move. This fricative sound suggests the progressive stage of arthritis, meaning that the cartilage, which acts as a cushion between the bones, has almost disappeared.
◇ If you have symptoms of knee locking with sound
Knee locking symptoms refer to a condition in which restrictions on motor functions that do not stretch and bend well when the knee is bent and unfolded. If the joint is locked with sound, it is likely due to damage to the meniscus cartilage or the vitreous body within the joint (a piece of cartilage that has fallen off). In particular, the feeling of something getting stuck in the joint can occur when a part of the torn cartilage plate is caught between the joints, so quick treatment is needed.
The symptoms of knee locking can be regarded as simply temporary discomfort, but if left unattended, there is a risk of further damage to the joint. Depending on the situation, some of the cartilage plates torn by arthroscopy may need to be resected or sutured.
◇ When you feel swelling, heat, and joint instability
If the knee is accompanied by swelling, heat, or joint instability with sound, this should consider damage to the cruciate ligament. Knee ligament damage mainly occurs during sports activities, and large external forces can occur in rapid changes in direction or rotational movements such as soccer and basketball, causing pain with a sound of 'tuk' and swelling of the knee. At this time, you should stop exercising immediately, relieve symptoms through cold compress, and visit a hospital.
Heo Dong-beom, the head of the hospital, said, `It is common to hear a sound from the knee, but it may not be a big problem if there is no pain or discomfort. However, if symptoms such as pain, swelling, and instability appear, there may be serious damage to joints or cartilage, so it is most important to protect knee health through early diagnosis and treatment.'
