45 year old female with large tibial OCL and pain with activity. Surgical management?

Question(s) to this case:

How to approach this surgically? Graft from inside, or open cortical window from outside?


Cortical window with curetting the cyst and destruction of the cyst wall into bleeding bone followed by a massive autologous bone graft should best be done. Try to identify the opening from the joint to the cyst and curette the entrance.
