Our specialists at CVFA provide advanced treatment options to help relieve the pain from ankle injuries such as an osteochondral injury of the talus.
The cartilage lining of the anklebone can be bruised when an ankle sprain occurs. As the anklebone (the talus) twists inside its box-like housing, the edge of the talus rubs up and hits the end of the tibia. This causes a bruise and leads to softening of the cartilage. It may lead to a small crack in the cartilage and a cyst forming in the talus bone.
This is an osteochondral injury of the talus, or osteochondritis dissecans.
There are many grades of severity of an osteochondral injury to the talus. Minor events lead to bruising of the talus. If the injury is more severe, large pieces of bone and cartilage can break off and lie loose in the ankle joint.
