[Objective]To introduce the surgical techniques and preliminary clinical results of intra-articular osteotomy for old tibial plateau fractures.[Methods]A total of 15 patients underwent intraarticular osteotomy for old intraarticular fracture of the tibial plateau.As the original fracture line was identified if the fracture was not healed,an osteotome was inserted through the original fracture line,and the fracture block was split and the intra-articular osteotomy was performed.If the fracture was healed,two parallel Kirschner pins were insert-ed at the most obvious point of the deformity,and the intra-articular osteotomy was performed along the Kirschner pins.The osteotome was inserted to the subchondral bone and pry to restore the height of the tibial plateau,and bone grafts were implanted in the bone defect area to support,finally plate fixation was conducted.[Results]All the patients were operated successfully without complications such as vascular and nerve injury,while with operation time of(119.1±26.3)min.All the osteotomy were healed with a mean clinical healing time of(19.3±3.1)weeks.At the last follow-up,Lysholm's knee joint score was of(89.9±4.6),with the excellent and good rate of 93.3％.There were no complications such as loosening of internal fixation,fracture and loss of correction.[Conclusion]This intraarticular osteotomy does effec-tively restore the congruity of the articular surface of the tibial plateau and reconstruct the alignment of the lower extremity,and has a good effect for old intraarticular fracture of the tibial plateau.
