Crunching when bending the knee is usually not a calcium deficiency, and physiological popping and pathological popping are considered.
Slight calcium deficiency generally has no obvious clinical symptoms, while severe calcium deficiency will cause weakness, low back pain, spinal deformation and even fragility fracture. However, calcium deficiency generally does not cause the leveling of joint surfaces in the knee joint area, and generally does not cause symptoms of joint rattling.
Knee creaking when bending, may be physiological popping, mainly when the knee joint bending, the liquid and gas inside the joint for extrusion of the sound.
If there are some joint diseases, such as knee osteoarthritis, meniscus injury, osteophytes, etc., these diseases will affect the joint surface of the knee area flat, in the bending of the friction caused by creaking.
When the knee bends, the creaking sound should go to the hospital in time to consult the doctor, after clarifying the cause of standardized treatment, to reduce the adverse effects of the disease.
