This study from the US came out a couple weeks ago if I’m not mistaken. It was published in the Journal of Orthopaedic and Sports Physical Therapy (JOSPT).

This was a prospective cohort study.
Participants: 115 young athletes (88 females)
RTS Criteria used:
- International Knee Documentation Committee subjective form (IKDC)
- Quadriceps and hamstring strength limb-symmetry indices (LSI)
- Single-leg hop test LSI
The proportions meeting cutoffs for all hop tests (=53.0%), all strength tests (=27.8%), and all combined measures (=13.9%).
“A higher proportion of participants who met cutoffs for both strength tests maintained the same level of sports participation over the year following RTS clearance than those who did not (81.3% vs. 60.2%; p=0.02).”
“The proportions of young athletes after ACLR recently cleared for RTS meeting combined criteria cutoffs were low. Those who met cutoffs for both strength tests maintained the same level of sports participation at higher proportions than those who did not.”
The percentage of athletes in this cohort who met all the cutoffs was only 13.9%! That is shockingly low. Even those who only met the strength tests were only 27.8%. Again I don’t know the details of the cohort. But results showing that those who met the strength tests who were able to maintain their level of sports participation over one year after RTS clearance there was not a large difference (81.3% vs 60.2%), compared to those who did not met the strength tests criteria.
I would really need to read the full paper before I can comment more on it.
