Objective Sartorius muscle was applied to treat dislocation or subluxation of patella and extension disorder of knee resulted from poliomyelitis,patellectomy and quadriceps femoris injury.Method The distal one third part or two thirds part of sartorius muscle excluded its insertion was freed,then transposed and threaded to the front surface of patella.Result 30 cases(37 knees)with dislocation or subluxation of patella were treated and 25 cases(28 knees)were followed up(mean followed up time 4 years).pain in the patello femeral joint disappeared without any recurrence of dislocation.75 with weak extensor of knee were treated and 50 were followed up for mean 2 years and 1 month.The extensor strength in the patients with poliomyelitis increased from 0.89 preoperatively to 2.76 postoperatively.The joint movement in the patients with extension stiffness of knee increased from 15° preoperatively to 102° postoperatively.The extensor strength in the patients with patellectomy increased by 2 grades postoperatively
