Advantages and Limitations

Advantages	Limitations
Prevents stretching and failure of the grafts in cases of concomitant chronic PLC or ACL instabilities and varus malalignment	Risk of tibial fracture
Possibility to perform a biplanar correction, which can be adjusted according to the instability	Need for an 8-week period of nonweightbearing
In some patients, the correction of varus malalignment reduces the instability complaint	Risk of consolidation problems is higher in opening osteotomies, when compared with lateral closing osteotomies.
Opening wedge osteotomies allow for better control of the correction	Big corrections may be better addressed with a distraction opening technique or double osteotomy
For treatment of early degenerative disease of the medial compartment, proximal tibial osteotomy can delay the need for a joint replacement procedure.	Big changes in bony anatomy can challenge future conversion to a knee replacement

ACL, anterior cruciate ligament; PLC, posterolateral corner.
