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.

Frobell et al (2010) - Early ACL Reco + Rehabilitation compared to  Rehabilitation +Delayed ACL Reco if required (2 and 5 year follow up)


  • 120 patients between -18-35 yrs  (Sub elite, recreational athletes) 
  • OUTCOME - Early ACLR and Rehab NOT superior to Rehab and Delayed ACLR (if required) at 2 and 5 years for KOOS (a questionnaire that compares pain, function in sport and recreation and knee related quality of life)

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


  • 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%
