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%
Not meeting criteria - 42 athletes Non discharged (27%) (14/42 had a graft rupture) = 33%
Overall 4 x greater risk of re rupture if not meeting 6 return to sport (RTS) criteria
Limitations - Only included males – thus these numbers could be significantly greater if extrapolate to include females whom have a higher risk factors
Only professional athletes were included. Therefore a higher level of rehabilitation than for example the general public as they have a) the time and b) access to the resources
No neuromuscular control or movement analysis was undertaken
This shows that it is imperative to have a non-biased RTS test to decrease your likelihood of graft rupture
