Only a single bundle repair of a double bundle ligament means the knee is left rotationally less stable (10), The graft tendon goes in at a steeper angle than the original ACL; hence its more likely to shear and fail (9), No working position sensors in the tendon repair of a ligament mean less position sense (6-8), High likelihood of developing arthritis/doesnt prevent arthritis (11,12), Higher chance of tearing the ACL on the other knee (13), The hamstrings or quadriceps muscles become weaker due to the graft harvest (14), A much less invasive procedure than surgery.
