Introduction
Tendons usually refer to tendons or ligaments. In general, a ganglion cyst itself does not contain tendons or ligaments. Avoid overuse and repeated friction of joints to reduce the risk of local injury. If the cyst is small and causes no discomfort, no special treatment is needed; however, if symptoms such as nerve or blood vessel compression, or restricted joint movement occur, seek medical evaluation promptly. After treatment, take care to protect the affected area.
Tendons usually refer to tendons or ligaments. Under normal circumstances, a ganglion cyst itself does not contain tendons or ligaments. The detailed explanation is as follows:
A ganglion cyst is a fluid-filled lump that develops near a joint within the tendon sheath. Its core component is joint fluid or synovial fluid, which accumulates abnormally due to degeneration or injury of the connective tissue in the tendon sheath. The outer layer of the cyst is composed of fibrous connective tissue membrane, while the interior contains only clear, transparent, or slightly yellowish viscous fluid. It does not include the fibrous bundle structure of tendons or the dense connective tissue components of ligaments; therefore, it does not inherently contain tendons or ligaments.
To prevent excessive joint strain and repeated friction, minimize the risk of local injury. If the cyst is small and causes no discomfort, special treatment may not be necessary. However, if symptoms such as nerve or blood vessel compression, or restricted joint movement occur, seek medical evaluation promptly. After treatment, protect the affected area and avoid strenuous activity in the short term to reduce the likelihood of recurrence. There is no need for excessive concern—proper care is sufficient to maintain normal joint function.
