What Causes Burning Pain in Your Knee?
Medically reviewed by Andre Stone | MD, University of Pittsburgh School of Medicine on August 25th, 2026.
Burning knee pain typically results from nerve irritation, inflammation, or tissue damage in the joint structures. Common causes include patellofemoral pain syndrome, which affects up to 25% of active adults, osteoarthritis causing cartilage breakdown, and IT band syndrome from overuse. Nerve compression conditions like meralgia paresthetica can create burning sensations along the outer thigh extending to the knee. Inflammatory conditions such as bursitis or tendinitis also produce burning pain, especially during movement. Other causes include ligament injuries and pain referred from the hip or back. Rarely, an infection or blood clot may be responsible. Seek urgent medical care for knee pain with marked swelling, warmth, redness, or fever, or for leg symptoms accompanied by chest pain or shortness of breath. The location and timing of burning pain helps identify the underlying cause.
