Kyritsis et al (2016) Likelihood of ACL graft rupture: not meeting six clinical discharge criteria before return to sport is associated with a four times greater risk of rupture

Summary

• For every 10% loss of HS/Quads ratio = 10.6 x likelihood of graft rupture  

• This ratio is increased if quadriceps strength is not fully regained to pre operative level

• Meeting the 6 criteria - 116 athletes Discharged (73%) – (12/116 had a graft rupture) =  10%
