Wedge high tibial osteotomy
Patient with arthritis in the medial compartment of the left knee, a varus malalignment and chronic pain presents for opening wedge high tibial osteotomy with bone grafting and fixation. Incision was made and dissection carried through subcutaneous tissue. Tibiofibular joint was exposed, the tibia was sized and the guide was set and brought onto the operative field. The guide pins and hinge pin placement were confirmed via fluoroscopy. Holes were drilled and the osteotomy was performed around the tibia. The osteotomy was slowly opened up and the appropriate guide pins were placed. OSferion wedges were mixed with the patient’s platelet rich plasma (PRP) and a mixture of the patient’s own autograft and demineralized bone matrix (DBM) mixed with PRP was placed to fill in the osteotomy site and the plate and screws were appropriately placed. A C-arm was utilized to confirm proper placement of the implants. How is an opening wedge high tibial osteotomy coded? ...
