Baker's Cyst

When repetitive load accumulates on the knee, the synovial membrane is continuously irritated, causing it to produce excessive synovial fluid. In this state, if intra-articular pressure rises, the anatomically vulnerable synovial membrane in the sciatic region is ruptured, forming a Baker's cyst. The incidence is high among occupational groups involving delivery work, climbing stairs, and sitting on a heavy cross-legged position; if accompanied by cartilage damage or arthritis, the cyst grows more rapidly. From a Korean medicine perspective, repeated overexertion depletes vital energy and damages tendons and muscles. When the supporting function of tendons and muscles weakens, the elasticity of the ligaments and tendons around the knee decreases, reducing the structural support capacity that holds joint fluid. When this is combined with the accumulation of waste fluids due to impaired digestive and metabolic functions, it creates an environment where fluid-filled cysts are prone to forming in the popliteal fossa. At Dongjedang, we promote simultaneous structural and functional recovery by relaxing hardened fascia and ligaments with special flat-tipped needles and inducing tissue regeneration through thread embedding therapy, while using herbal medicine that reinforces tendons, muscles, and digestive and metabolic functions.
