Why does the knee suddenly 'soft' when walking? Or these 4 reasons are 'blame', let's find out
The knee joint is located at the connection part in the middle of the lower leg and consists of the meniscus and the quadrilateral tendon, which can relieve the vibration of the knee joint, prevent the two bones of the lower leg from rubbing immediately, and play a maintenance role. It's just that in daily life, many people's knee joints will have some difficulties. For example, when walking, there will be a sudden softening of the knee joint, which is called knee joint softening. Once this happens, it is easy for people to fall, which is extremely harmful to physical and mental health.
Many people wonder what is the reason for this situation.
Why do my knees suddenly go soft when I walk? After reading, you may understand.
First, the meniscus is damaged
A key cause of sudden knee weakness while walking is related to meniscus damage.
For example, knee twisting, or long-term weight-bearing squatting, knee osteoarthritis, will cause some damage to the patient's meniscus.
If the injury is minor, not easily jeopardizing all the subject activities of the patient, there will only be some pain in strong postures.
When the patient walks, the fractured extension and flexion joint will be stimulated and cause pain, which will cause the joint to suddenly soften.
If the condition is severe, the patient will experience significant knee pain in daily life, and the subject activities of the knee joint will be limited.
The snapping sound of the knee joint also continued to occur when the patient was in a squat position.
Second, the synovial fold syndrome of the knee joint
Knee synovial fold syndrome refers to the constant irritation or damage of the synovial fold skin of the knee joint, which leads to the transformation and growth of the synovial fold, resulting in instability and pain of the knee joint.
Especially when the knee joint is subjected to violent collision, or long-term meniscus injury, or suffering from knee joint synovitis and other diseases, it will cause the synovial folds to become inflamed, swollen, hypertrophic, and adherent, thereby losing ductility.
In this way, when the patient walks, the joint part will be extruded and formed, so that the knee joint part of the patient suddenly becomes soft when walking.
Third, the femoral neck joint is unstable
Especially for some women, the bone joints are very unstable.
A sudden flexion or force in the knee joint while walking can cause a strong stretch of the femoral neck and its quadriceps.
In this way, the neck of the femur will be stimulated, and the knee joint will suddenly become sour when walking. Especially during weight-bearing walking, there will be momentary weakness and instability in the knee joint.
In severe cases, the patient may even fall instantly.
If it is caused by the instability of the bones and joints, the patient often has dull pain in the anterior and medial knees in daily life. For example, in the case of left and right indoor stairs, this pain will be more obvious.
Fourth, osteoarthritis
Osteoarthritis is a chronic joint disease mainly caused by damage to articular cartilage tissue and can cause damage to all joint mechanisms.
The etiology has not yet been determined, but it is generally believed to be related to excessive obesity or the occurrence of certain inflammation, joint instability and other factors.
When a patient's knee joint becomes ill, pain and swelling often occur. Moreover, due to the stimulation of inflammation, the muscles of the whole body around the knee joint will suddenly appear in a state of muscle spasm, which makes the feet suddenly become soft when walking.
Generally speaking, if the feet often become soft when walking, it is usually related to the above four factors.
For those who are overweight or obese or pregnant, the occurrence of this situation is likely to be related to calcium deficiency.
Conclusion: Therefore, when such diseases continue to occur, we must not relax our vigilance, and quickly go to the hospital outpatient clinic for corresponding examinations, and then give corresponding treatment according to the cause of the disease, in order to improve such diseases to a greater extent.
