Massachusetts General Brigham Sports Medicine
• Progress intensity (strength) and duration (endurance) of exercises
**The following exercises to focus on proper control with emphasis on good proximal stability
• Lateral step down
• Squat to chair
• Lateral lunges
• Romanian deadlift and Single leg deadlift
• Single leg progression: partial weight bearing single leg press, slide board
lunges: retro and lateral, step ups and step ups with march, split squats, lateral step-ups, step
downs, single leg squats, single leg wall slides
Balance/proprioception
• Progress single limb balance including perturbation training
• Lower quarter reaches (Y-Balance and Star drill)
**When Quadriceps index > 80% strength:
• Interval running program
o Return to Running Program
• Progress to plyometric and agility program
o Agility and Plyometric Program
• No swelling/pain after exercise
• Ability to perform ADLs pain free
**If patient is returning to impact activities:
• 10 repetitions single leg squat proper form through at least 60 deg knee flexion
• Drop vertical jump with good control
• Completion of jog/run program without pain/swelling
• Functional Assessment
o Quadriceps index >80%; HHD mean preferred (isokinetic testing if available)
o Hamstring, glut med,glut max index ≥80%; HHD mean preferred (isokinetic testing for HS if
available)
o Single leg hop test ≥75% compared to contra lateral side
PHASE IV: UNRESTRICTED RETURN TO SPORT (9-12 WEEKS AFTER SURGERY)
• Maintain full ROM
• Safely progress strengthening
• Promote proper movement patterns
• Avoid post exercise pain/swelling
• Return to all necessary and desired functional activities, work duties, and athletic activities

applicable to athlete
*Continue with Phase
I-III interventions
• Multi-plane sport specific plyometrics program

• Last stage, no additional criteria
• Functional Assessment
o Quadriceps index >95%; HHD mean preferred (isokinetic testing if available)
o Hamstring, glut med, glut max index ≥95%; HHD mean preferred (isokinetic testing for HS if
available)
