Eccentric exercises (such as squat descents) are a standard rehabilitation method for patellar tendinitis and are effective for long-term prognosis. However, they are difficult to perform during the acute pain phase, and in the chronic tendinosis stage, an approach that directly stimulates tissue regeneration is required. Acupuncture stimulation regulates inflammatory mediators such as PGE2 through peripheral nerves and local blood flow, while needle insertion directly dissects nodules and adhesions within the tendon to promote collagen rearrangement. Korean Medicine Clinic Perspective In Korean medicine, tendon healing is possible only when the body's vital essence and fundamental energy are replenished. Chronic patellar tendinitis is often rooted in systemic functional decline beyond simple overuse. At Dongjedang, we directly induce tendon regeneration signals using needle insertion and thread shedding, and add local anti-inflammatory effects with pharmacopuncture (bee venom, Coptis japonica, etc.). In addition, herbal medicine tailored to your constitution flushes out stagnant blood and waste products and restores Qi and blood circulation, accelerating the recovery speed when combined with rehabilitation exercises.
