Five Months Post-ACL and Ten Weeks From Kickoff
A 22-year-old recreational soccer player is five months post ACL reconstruction with a hamstring graft. Her physical therapy discharge note reads: cleared for supervised strength training; no plyometrics, no cutting, no squats past 90 degrees of knee flexion until nine months post-op; refer back if effusion increases. She has full extension, 128 degrees of flexion, quadriceps strength at 70% of the uninvolved side by handheld dynamometry, and no effusion today. She wants to be ready for a spring league that starts in 10 weeks and can train three days a week for an hour. She has already been jogging on her own a little and says it feels fine.
1. Given the note, what can and cannot you do in the next 10 weeks? Name the conflicts.

Read the note as a hard boundary, not a suggestion. The plyometric, cutting, and deep-squat restrictions run to nine months post-op. She is at five months, so that date is roughly four months after her league starts. The league start is not a variable you can negotiate; graft remodeling does not respond to motivation.
The self-directed jogging is conflict number one. Jogging is not in the note, and 'it feels fine' is not a criterion. Do not build on it and do not tacitly endorse it. Tell her plainly that you are calling the PT to ask whether jogging is permitted, and hold it until you get an answer.
What you can do: strength work in a restricted range (box squat to a 90-degree box, Romanian or trap-bar deadlift, hip thrust, leg press within range, split squat with the front foot elevated to keep the knee angle legal), high-volume quadriceps work, cycling, pool work, linear low-intensity conditioning, single-leg balance and stability, upper body, and trunk.
The 70% quadriceps symmetry is your real project. It is the single most modifiable risk factor she has, and it is not fixed by getting on the field sooner.
2. Write the weekly priorities and the progression rule you will use for those three sessions.

Day 1, strength A: box squat to 90 degrees 4 x 5 at RPE 7; Romanian deadlift 3 x 8; split squat with front foot elevated 3 x 8 per side; calf raise 3 x 12; trunk work.
Day 2, strength B plus unilateral: leg press in restricted range 3 x 10; hamstring curl or Nordic 3 x 6; step-down 3 x 8; hip thrust 3 x 10; single-leg balance reach 3 x 30 s; upper-body push and pull.
Day 3, conditioning plus quad volume: bike 25-30 minutes steady; Spanish squat or terminal knee extension 3 x 30 s; leg extension 3 x 12-15. Add no plyometric substitute unless the PT clears it.
Progression rule: add 5-10% load when a session is completed with no effusion increase at 24 hours and no pain above 2/10. Measure quadriceps strength every four weeks and chase the symmetry number, not the calendar.
Reframe the goal with her in week one: the objective is to be strong, symmetric, and unrestricted at nine months so she can do a proper return-to-sport progression then. The 10-week league start is not a training target; it is a conversation she needs to have with her surgeon and PT, not with you.
3. What findings would make you stop and call the physical therapist or physician?
Read the worked answer
Pick up the phone when any of these appear:
- New or increased effusion that does not settle within 24-48 hours, measured at the same landmark at the same time of day.
- Any giving way, catching, or locking.
- Loss of full knee extension. This one is urgent, not wait-and-see.
- Pain above 3/10 during exercise, pain lingering the next day, or night pain.
- Quadriceps symmetry stalls below roughly 80% after six to eight weeks of well-executed work, or regresses.
- She reports cutting, jumping, or sport drills on her own, which is both a scope issue and a safety issue, and the PT should know.
- Any request from her, or from a coach, that you clear her for sport.
Document every contact: date, who you spoke with, what was decided, and what you changed. That record protects her knee and protects you.
