[Objective]To evaluate the result of operative treatment of tibial plateau fracture and analyze its related factors of influencing the therapeutic effect and provide effective prevntional measures.[Method]Totally 107 cases(male 62 cases;female 45 cases) of tibia plateau fractures were operated with internal fixation from Feb.2000 to Apr.2005 in our hospital.According to Schatzker classification,there were typeⅠfracture 2 cases,typeⅡ 37 cases,typeⅢ 29 cases,type Ⅳ 22 cases,type Ⅴ 10 cases,type Ⅵ 7cases.TypeⅠfractures were treated with cannulated screws,other type fractures were performed with open reduction and internal fixation with buttress plates and autologous and/or allograft bone grafts.Therapeutic effect and its related factors were analyzed concomitantly.[Result]The 107 patients were followed up for 9~64 months(averaged 27 months).The clinical results were assessed according to Hohl scale for knee joint.The excellent and good results was 85.98%.There were obvious complications articular stiffness 1 cases and traumatic arthritis 8 cases including tibia plateau articular depression 4 cases.[Conclusion]Surgical operation is effective methods of treating tibia plateau fracture,The complete fracture reduction suitable internal fixation a good protection and recovery of the soft tissue of the knee joint structure,and correct and effective function rehabilitation are the significant measures for good therapeutic effect in the treatment of tibia plateau fracture.
