Common Causes of Knee Pain
Osteoarthritis: This degenerative joint disease is a leading cause of knee pain, especially in older adults. It occurs when the protective cartilage that cushions the knee joint wears down, leading to pain, stiffness, and limited mobility.
Injuries: Knee pain can result from various injuries, such as ligament tears, meniscus tears, sprains, or strains. These injuries can occur during sports activities, accidents, or repetitive stress on the knee joint.
Overuse and Tendonitis: Overuse of the knee joint, often due to repetitive motions or excessive strain, can cause inflammation and tendonitis. This condition commonly affects athletes and individuals engaged in activities that involve repetitive knee movements.
Bursitis: Bursae are small, fluid-filled sacs that provide cushioning between bones, tendons, and muscles. Inflammation of these sacs, known as bursitis, can lead to knee pain and limited range of motion.
Rheumatoid Arthritis: An autoimmune disease that affects multiple joints, including the knees, rheumatoid arthritis causes chronic inflammation, pain, and swelling in the joints, leading to joint damage if left untreated.
