Abstract：Objective To investigate the application of tibial tubercle wedge osteotomy in treatment of severe stiff knee with total knee arthroplasty，analyze the clinical result and surgical technique，and provide reference for the selection of clinical operation.Methods 23 cases diagnosed as stiff knee since May 2005 to October 2014 underwent total knee arthroplasty.All patients were followed up，mainly evaluated from the visual analog scale (VAS)，the function of the knee score (KSS) and range of motion (ROM).Results All the patients were successfully performed without any severe complications.All patients with osteotomy healed within 5 months，VAS score reduced by preoperative (5.25± 1.56) points (range 4～8 points) to postoperative (1.26±0.64) points (range 0～4 points)，KSS score improved from preoperative (42.76±7.80) points (range 35～56 points) to postoperative (90.05±17.24) points (range 67～92 points).Knee range of move improved from preoperative (52.36±24.45)° (range 15°～80°) to (90.15±17.56)°(range 60°～ 110°) at the time of last follow-up.Conclusion Tibial tubercle wedge osteotomy technique is an effective and safe approach to increase the exposure of the knee joint，wedge osteotomy can disperse the stress loaded on screws，and give continuous dynamic compression between fractures to increase the healing rate.Wedge osteotomy also can correct alignment of the lower limbs to obtain good clinical results.
