That's what I was suggesting. There are a few papers out regarding use of ankle scope to assist with ankle, or esp pilon, fx repairs. There's also STJ scoping during calc fx repairs. Just like the tibial plateau I was in on yesterday, the idea is just to use the scope to see the joint surface, recognize stepoffs, defects, etc and debride or excise damaged cartilage fragments better than you could with just intra-op XR... and with less incisions and soft tissue damage than traditional open approach.
For the plateau, it was neat since you could see just where the tips of the guide pins were hitting, that the screws were engaging, etc without opening up the joint widely.
