anterior cruciate ligament （ACL） reconstruction is usually recommended for young patients. Several recent articles have however reported comparable outcomes of ACL reconstruction between youth and patients in fourth or fifth age group. But in the literature there are not many reports about ACL reconstruction in patients over 70 years old. We report a case of a successful arthroscopic ACL reconstruction （using single bundle quadrupled hamstring graft） in an active 75-year-old medical practitioner. Successful outcome after ACL reconstruction can be achieved in selected older patients; chronological age is no barrier.

BACKGROUND Suspension training(SET)is a method of neuromuscular training that enables the body to carry out active training under unstable support through a suspension therapy ***,there have been few reports in the literature on the application of SET to anterior cruciate ligament reconstruction(ACLR)*** is not clear what aspects of the patient's function are improved after *** To investigate the effect of SET on the neuromuscular function,postural control,and knee kinematics of patients after ACLR *** Forty participants were randomized to an SET group or a control *** SET group subjects participated in a SET protocol over 6 *** control group subjects participated in a traditional training protocol over 6 *** muscle strength of the quadriceps and hamstrings,static and dynamic posture stability test,and relative translation of the injured knee were assessed before and after *** The relative peak torque of the quadriceps and hamstrings in both groups increased significantly(P0.05).CONCLUSION Our findings show that SET promotes great responses in quadriceps and hamstring muscle strength and balance function in ACLR patients.
