45 year old male with ocl

Question(s) to this case:

do you think this is new or old finding? what would you do? scope? debride? fix through osteotomy? observe?

Expert:

This is a preexisting OCD: there is osteofyte on talus and small cystic lesion (sagital reconstruction: posterior). The patient had no symptoms before: therefor stay conservative. If complaints of deep ankle pain persist then debridement and bone marrow stimulation
