Return to Sport After ACL in the Young Athlete

• In youth aged 6-18 y.o., ACL injuries occur at a rate of 130/100,000 people per year
• Rate of ACL tears rising 2.5% yearly in teen girls, 2.2% annually in teenboys
• Incidence of injuries in young athletes :– Year-round competition– Early specialization– Intensive training
The ACL epidemic
![Page 3: Return to Sport After ACL in the Young Athlete › static... · Return to Sport After ACL in the Young Athlete Stephanie Gould Pht, Naudira Stewart P.R.T ... • Neuromuscular training](https://reader033.vdocuments.mx/reader033/viewer/2022053008/5f0bcc297e708231d4324373/html5/thumbnails/3.jpg)
• Rates of re-injury:– In young athletes (<20-25y.o) =
approx 23%– Studies report rate of re-injury of the
same knee as high as 29%– Studies report rate of ACL tear in the
contralateral knee is as high as 19%• Rates of return to sport:
– Only 40-65% return to previous levelof sport activity
– Despite 90% presenting with normal knee function (Stability, ROM and strength)at 6-9mos post
Reconstruction Surgery, Not a Magic Pill

• How to know if/when a young athleteis ready to return to sport?? – No consensus in RTS Criteria– And very few protocol use functional
criteria to assess readiness for RTS• Best way to get them there??
– No consensus in rehab protocols
WHY CAN’T WE ALL JUST AGREE?
![Page 5: Return to Sport After ACL in the Young Athlete › static... · Return to Sport After ACL in the Young Athlete Stephanie Gould Pht, Naudira Stewart P.R.T ... • Neuromuscular training](https://reader033.vdocuments.mx/reader033/viewer/2022053008/5f0bcc297e708231d4324373/html5/thumbnails/5.jpg)
• Time after surgery continues to be the dominant criteriafor RTS
• Recommended time before RTS varies in the literatureanywhere from 3 to 12 months! (Kvist, 2004)
• BUT:– Neuromuscular deficits can persist > 11 mos– 9/10 fail quad power @ 6 mos (Neeter, 2006)– Complete ligamentization takes 10-12mos in humans
(Li, 1993)• Also, if magical projected return time passes, frustration
mounts and this becomes mentally challenging.
Timing isn’t everything

Factors Affecting Athletes Return to Sport
• Pre-injury status• Associated knee injuries• Time to treatment / time to
surgery• Surgical technique• Knee kinematics• Rehab protocol• Compliance• Achieved level of muscle
function
• Patients activity level
• Social factors (family, work, etc)
• Functional knee stability
• Knee symptomatology
• Motivation
• Level/intensity of sport
• Psychological factors

Challenges with Teenage Athletes
• Risk-taking behaviours• Socialization/peer-pressure• Attention span• Motivation levels• Physiological and mental immaturity
IMPORTANT TO WORK WITH A THERAPIST WHO HAS EXPERIENCE WITH YOUNG PATIENTS AND WHO CAN MAKE THERAPY SESSIONS ENGAGING AND
BENEFICIAL!

Rehab: Pre-operative Phase
• 1 (or more) appointment to teach home program– Ensure full ROM, strength pre-operatively– Wean from knee immobilizer ASAP– Bike ++, ROM, stretch, strengthen (incl hips,
core), proprioception
![Page 10: Return to Sport After ACL in the Young Athlete › static... · Return to Sport After ACL in the Young Athlete Stephanie Gould Pht, Naudira Stewart P.R.T ... • Neuromuscular training](https://reader033.vdocuments.mx/reader033/viewer/2022053008/5f0bcc297e708231d4324373/html5/thumbnails/10.jpg)
• Eliminate pain/swelling• Restore full knee extension
ROM• Gradually progress knee flexion
ROM• Maintain patellar mobility• Restore volitional quads control• Restore independent
ambulation
Rehab: Weeks 1-4

• Closed kinetic chain exercises• Progressive hamstring strengthening• Quadricep strengtheing with emphasis on
Eccentric control• Proprioception• Core and glute strengthening
Rehab : Weeks 4-12

• 12 weeks: start training in a gym (including leg press, legcurls)
• 20 weeks: start jogging at PT discretion• 24 weeks: first isokinetic testing to determine readiness
for plyometrics and sports-specific training in the therapeutic setting
Rehab: Weeks 12-24

1. Running/ sprinting 2. Straight line stops/starts3. Bilateral Plyometrics4. Lateral shuffles5. Running figure-8s6. Backwards running7. Cutting/pivoting8. Closed space agility drills9. Cariocas10. Single leg hops (progressing
difficulty)
Progressive Sports Training (starting at Month 6 )
Once the athlete has passed the Isokinetic testing with favorable results RTS training begins
![Page 14: Return to Sport After ACL in the Young Athlete › static... · Return to Sport After ACL in the Young Athlete Stephanie Gould Pht, Naudira Stewart P.R.T ... • Neuromuscular training](https://reader033.vdocuments.mx/reader033/viewer/2022053008/5f0bcc297e708231d4324373/html5/thumbnails/14.jpg)
• Time since surgery• Knee ROM/absence of joint effusion• Knee joint stability• Strength• Proprioception• Dynamic knee function• Neuromuscular function• Aerobic capacity• Sports-specific testing• Psychological readiness
Crucial Factors in RTS (Barber-Westin & Noyes, 2011)
A battery of tests is best to assess readiness for return to sport – Noyes et al

• Return to sport is a PROCESS• Games + team practice brings chaos and high
speed, require quick reactions and confidence• Start with individual skills, then partner drills,
group drills, game simulation drills, practice games, partial games, then finally completegames
But wait …

Maintenance after Discharge • Don’t neglect a program of PREVENTATIVE exercises
– PEP program, FIFA-11 program• Neuromuscular training decreases an adolescent female
athlete’s risk of ACL injury by 72%• Program should include plyometric training, technique
training, ++ feedback about proper form, and continuedstrength training

Conclusion
“ When you candemonstrate that you
are ready! ”
“ When can I go back to my sport? ”
