Thanks for posting your query.
Desscans (OCD), there is a loss of blood supply to a segment of bone and cartilage in the talus bone of the ankle. If it is not healed after nonweight bearing for 3 months, you need surgical treatment
Initial treatment involves arthroscopy
to remove severely damaged fragments or drilling through the area with no blood supply into adjacent healthy bone. This allows blood supply to enter the injured area and encourage healing. In severe cases, when drilling is not effective, a new procedure allows the transplantation
of new cartilage and bone into the defect.
So discuss these surgical options with your orthopaedic surgeon
Wishing you good health
