Objective To analyze the causes of postoperative step off of the tibial plateau fracture and to suggest strategies to cope with them. Methods 57 cases of tibial plateau fracture who had been treated operatively in our department from January 2001 to June 2003 with satisfactory reduction of the articular surface were reviewed. Their radiograms were analyzed. Results The follow ups lasted 6 to 30 months (average 15 months). Postoperative step off rate was 28.1%in all the cases according to radiological step off criteria. (A depression of the articular surface more than 3 millimeters or malalignment of the extremity more than 5 degrees is considered as step off.). Six causes of loss of reduction were 1) more than sixty years of age, 2) severe osteoporosis, 3) preoperative displacement and fracture fragmentation, 4) poor anti shearing strength of screw and plate, 5) loose bonegraft, and 6) premature weight bearing. Conclusions The key points to enhance the outcome include precise judgment of the type of fracture, sufficient amount of bonegraft, rigid internal fixation after anatomic reduction and an appropriate plan for performing early, loadless, functional exercise. The traumatic osteoarthritis may be avoided or deferred if the above mentioned six causes can be taken into full consideration or preventive measures can be taken.
