Osteoarthritis:
As we age, the soft tissue called cartilage that prevents the bones in the knee from rubbing against each other wears down. This is the most common cause of knee pain in adults.
Injuries:
Ligament Injuries: Injuries to the ligaments in the knee (especially the ACL) can occur during sports activities.

Meniscus Tear: A tear in the cushion-like area between the bones in the knee.
Obesity:
As body weight increases, the knees take on more weight than they can handle, which puts a lot of pressure on the joints and causes pain.
Overuse:
Continuous climbing stairs, running, and strenuous exercise can strain the muscles and joints in the knee.
Arthritis:
Rheumatoid Arthritis: A condition in which the body’s immune system attacks the joints.

Muscle weakness:
If the muscles around the knee (especially the thigh muscles) are weak, the knee will not receive adequate protection and will experience pain.
