Knee Pain: Causes, Symptoms, Treatment and Prevention

Knee pain is one of the most common orthopedic complaints and can affect walking, climbing stairs, sitting, and daily work. It may develop suddenly after an injury or slowly due to arthritis, weak muscles, obesity, posture problems, or age-related cartilage wear.

Common causes of knee pain

Frequent causes include osteoarthritis, ligament injury, meniscus tear, patella tracking issues, tendon inflammation, bursitis, and sports-related trauma. Pain with swelling after a twist or fall needs prompt evaluation because ligament or meniscus injury may worsen without treatment.

Symptoms to watch

Warning symptoms include swelling, locking, instability, stiffness, difficulty bearing weight, pain at night, fever with joint swelling, or deformity. Early diagnosis helps prevent chronic stiffness and long-term joint damage.

Treatment options

Treatment depends on the cause. Many patients improve with rest, medicine, physiotherapy, strengthening exercises, weight control, bracing, and activity modification. In advanced arthritis or major injury, injections, arthroscopy, ligament reconstruction, or knee replacement may be advised after clinical assessment.

Prevention tips

Maintain a healthy weight, warm up before exercise, strengthen thigh and hip muscles, avoid sudden overloading, use proper footwear, and do not ignore recurring pain.
