ObjectiveTo investigate the clinical effect of arthroscopic treatment on anterior cruciate ligament (ACL) tibial insertion avulsion fracture. MethodsThe clinical data of 37 patients with ACL tibial avulsion fracture underwent arthroscopically assisted treatment of “8” suture method were analyzed retrospectively.ResultsAfter one year,in the subjective evaluation part of Rasmussen functional assessment, patients with 6 scores of postoperative pain, walking ability, joint stability, extension of the knee joint and knee joint activity, total score increased obviously compared with those before operation, and the difference was statistically significant (P＜0.05); In the part of radiologic evaluation, condylar variable width, angular deformity and total scores increased obviously compared with those before operation, and the difference was statistically significant (P＜0.05). After one year, the evaluation of knee joint function was evaluated by HSS system: excellent in 22 cases, good in 9 cases, median in 6 cases, poor in 0 cases, the rate of excellent and good was 83.78% (31/37). ConclusionIt has the advantages of reliable fixation, well recovered of knee joint function on the treatment of anterior cruciate ligament tibial insertion avulsion fractureunder the assist of arthroscope.
