Advantages and Disadvantages

Advantages	Disadvantages
1. Easy fixation of the posterior bone plug is possible in the tight medial compartment. 2. Secure fixation is achieved through bone-to-bone healing. 3. Only the posterior bone socket rather than the transtibial tunnel is needed.	1. There would be still concern about healing potential between the posterior bone shell of the graft and bone. 2. Making 2-mm-deep posterior bone shell is sometimes technically demanding and learning curve is in play.
