Leg Crackling and Knee Pain — Which Doctor Should I See?

Leg crackling with knee pain can result from patellofemoral pain syndrome, osteoarthritis, meniscus tears, or ligament injuries. Gas bubbles in joint fluid (cavitation) may also produce crackling sounds during movement.

Seek medical attention if crackling is accompanied by severe pain, swelling, instability, or if symptoms persist beyond two weeks. Immediate care is needed if you experience sudden injury or inability to bear weight.

Try RICE therapy (rest, ice, compression, elevation), over-the-counter pain relievers, and low-impact exercises. Maintain healthy weight and avoid activities that worsen symptoms until you receive a proper diagnosis.
