Talar Dome Lesion
The top of the talus (ankle bone) is dome-shaped and is completely covered with cartilage. A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. While symptoms may take months to develop, a talar dome lesion can cause pain, swelling, and more. This is why if you suspect some type of pain or injury to the ankle, it is important to have it diagnosed quickly.
