Dear,
Welcome to HCM.
A lot of joints crack and the knees are a really common joint to crack. When we squat or stand, sounds come from these rougher surfaces gliding across each other. It could also be the tissue that connects bones to other bones, called ligaments, tightening as you move, or the joint lining moving over bones.
If you have cracking or popping that does cause pain or swelling, though, see a doctor. It can be a sign of:
1.
Meniscus tears.
2.
Cartilage injury or wear.
Osteoarthritis is the most common kind of arthritis. It usually affects middle-aged and older people.
•Regular exercise can strengthen your legs and knees. Exercise with weights or resistance bands -- or do bodyweight moves, like squats and lunges -- at least twice a week. Walk up stairs or hills, or ride a stationary bicycle to build muscle to support your knees.
•Warm up before you exercise. An intense workout with
cold muscles and joints can cause injury.
Hope to have given you desired information.
Feel free to followup for any queries.
regards,
Dr. Selvavinayagam
