Objective　To evaluate the technique and outcome of arthroscopic anterior cruciate ligament(ACL) re-construction with autogenous bone-patellar tendon-bone.　Methods　From Jan. 2003 to Jan. 2010, 35 knees with ACL tear in 35 patients were verified with arthroscopy in this department. Of them, there were 22 males and 13 females, and the average age was 23.0 years (ranged from 20.0~28.0 years). The lesions were left knees in 18 and right knees in 17, and all were acute injuries and all the damaged ACLs were reconstructed with autogenous bone-patellar tendon-bone under knee arthroscopy. All patients were keen participants in sports.　Results　All patients were followed up for 1 to 6 years with an average of 3.0 years. The patients were evaluated according to the Lysholm knee scoring scale.The score was remarkable improvement from 45~81 points (mean 59.40 points) preoperatively to 72~100 points ( mean 91.80 points) at follow up (P<0.0001). Of the 35 patients, 34 patients returned to the same preinjury sports level and only 1 was below the preinjury sports level. There was no patellar fracture and loosing of the screws. Only one patient feel little pain in knee.　Conclusions　The autogenous bone-patellar tendon-bone with advantage of minimal trauma in surgery, reliable satisfactory outcome especially good for the youth who are keen participants in sports.
