Only 1 in 5 patients achieve limb symmetry at 6 months post ACL reconstruction

In early 2019 Cristiani et al published an article showing < 20% of patients met rehabilitation goals of having > 90% limb symmetry in strength (isokinetic quads and hamstrings at 90deg/sec) and single hop for distance tests at 6 months post-op.

This study had a very large sample size (4093 patients), comprising 45.7% females, with a mean age of 28 years (+/-10 years). 86.5% of participants completed the full test battery 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%
