Quote the sister upstairs: remove the false joint, use Ilizarov technique, lengthen the osteotomy under the tibial tubercle and pressurize the false joint. I'll correct some details: I don't need to remove it, I just need to remove it and keep that bone tissue. Pseudojoint needs osteotomy to rebuild blood supply, and then the following are basically the same: Ilizarov technique is used, osteotomy under tibial tubercle is prolonged, pseudojoint is pressurized, and limb shortening is corrected. We have done many examples, and the effect is very good.
