Knee pain is one of the common problems that many suffer when moving from sitting position to standing or vice versa, and this pain may be caused by various factors ranging from simple stress and chronic health problems, and the cause depends on age, the level of physical activity, and the presence of previous injuries or diseases related to the joints.
The gradual erosion of the cartilage and its effect on the knee
Cartilate erosion is one of the main causes of the pain when moving, as the cartilage works as a soft pillow that protects the bones from friction, but with the passage of time or because of excess pressure, this cartilage may begin to wear, which leads to bone friction together, and this results in pain when moving the joint, especially when sitting or standing after a period of rest.
Arthritis and its effect on the movement of the knee
Arthritis is one of the most common causes of knee pain, as osteo or rheumatoid arthritis can lead to joint stiffness and swelling, which makes movement painful, and symptoms are often more visible when sitting for long periods and then trying to rise, or when suddenly changed the position.
Muscle weakness and ligaments supporting the joint
The muscles surrounding the knee play an important role in supporting the joint and reducing pressure on it, and when weaken these muscles or infection of the ligaments that fix the knee, the joint becomes more vulnerable to pain when moving, and the lack of physical activity or sitting for long periods may lead to stiffness of the muscles, which increases the difficulty and pain associated with them.
Weight gain and its impact on knee health
Weight gain constitutes additional pressure on the knee joint, which speeds up cartilage erosion and causes pain when changing the position as studies indicate that every kilogram of weight increases the pressure on the knee joint four times, which makes people who suffer from obesity more vulnerable to knee pain, especially when standing after sitting or walking for long periods.
Previous injuries and their impact on the joint
The pain may be caused by ancient injuries such as rupture of ligaments or crescent cartilage injuries, as some injuries are not fully healing, which leads to pain when moving the joint in a certain way, and exposure to frequent knee bruises may lead to chronic inflammation in the tissues surrounding the joint.
