Wellsandt et al (2017) Limb Symmetry Indexes Can Overestimate Knee Function After Anterior Cruciate Ligament Injury

Comparison between single leg hop and quad strength – in two different ways.

Who - Non professional cutting athletes, 14-55 yrs old(Excluded other significant injuries).

Limb Symmetry Index (LSI) = comparison between Left and Right during an assessment.

Estimated pre-injury capacity (EPIC) = measuring uninvolved limb pre-operatively then comparing to the involved side at 6 months post-op.

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%
