Six Months After ACL Reconstruction and a League Start Date
Priya, 22, plays recreational basketball and is six months out from an ACL reconstruction using a hamstring autograft. Her formal physical therapy ended at five months, and she was told she was "doing great." She wants to be ready for a rec league that starts in six weeks and asks you to add cutting, jumping, and change-of-direction drills. Screening today shows full knee range of motion and no pain with straight-line jogging, but visible effusion after a 20-minute pickup game last week, two episodes of the knee "giving way" while cutting, and a single-leg squat on the surgical side with noticeable valgus collapse and a 3-second hold versus 20 seconds on the other side. Her last isokinetic quadriceps index from physical therapy was 78%, but she does not have the report. She squats 60 kg and deadlifts 70 kg comfortably and is highly motivated.
1. Priya asks you to start cutting and jump training today. What is your response, and which criteria are you assessing?

Response: not today. The findings point to an incompletely rehabilitated knee, and adding high-level plyometrics and cutting now loads a graft and a quadriceps that are not meeting the usual return-to-sport benchmarks.
The criteria I check, and where she sits:
- Quadriceps strength symmetry of at least 90% via isokinetic or handheld testing. Reported 78% fails, and I need the actual report rather than her recollection.
- Hop-test battery symmetry of at least 90% with clean landing mechanics. Not yet tested; her single-leg squat collapses into valgus, which predicts poor landing control.
- No effusion after sport-specific activity. She has effusion after a pickup game.
- No episodes of giving way. She reports two while cutting.
- Psychological readiness to return, which she has not been screened for.
What I say. I explain that these are objective screening thresholds, not opinions, and that giving way plus effusion are the two findings I am least willing to train through. I ask her to request the isokinetic report and to book a re-assessment with her physical therapist or surgeon. I put the request and my findings in writing.
2. She insists the league starts in six weeks. What do you actually program for those six weeks?

Framing. I do not promise return-to-sport in six weeks, because that decision is not mine. I promise to build the qualities that the criteria measure and to keep her communicable with her rehabilitation team.
Programming, two to three sessions per week:
- Bilateral and then unilateral strength: split squats, step-downs with controlled knee tracking, Romanian deadlifts, hip abduction work. Progress load, not complexity.
- Quadriceps volume, since that index is the clearest deficit: leg press, Spanish squats, terminal knee extensions, progressing to heavy slow resistance.
- Landing mechanics at low amplitude only, double-leg, once effusion has settled: snap-downs, low box landings. No cutting, no single-leg plyometrics, no sport practice at full speed.
- Straight-line running volume maintained or progressed modestly, since she tolerates it without pain.
Monitoring. Measure effusion (circumference and visual) before each session and 24 hours after. Any effusion or giving-way episode halts plyometric work and triggers a message to her physical therapist. Progress is gated on the criteria, not on the calendar.
3. Priya says a friend who is a trainer told her she is "cleared at six months." How do you handle the scope question?
Read the worked answer
The rule. Return-to-sport clearance after ACL reconstruction belongs to the surgeon, supported by objective testing usually performed by the physical therapist. Six months is a common average, not a clearance date, and a trainer cannot confer it.
What I say to her. I explain what I can and cannot do. I can train strength, power, conditioning, and movement quality, and I can screen and share findings. I cannot assess graft integrity, interpret her isokinetic report, or authorize contact and cutting sport. Her friend's statement is not clearance, however well intentioned.
What I do next. I ask her to sign a release so I can speak directly with her physical therapist, and I send my screening findings in writing. I ask the therapist what, specifically, I am permitted to add and when.
If she plays anyway. That is her decision, not something I can prevent. I document that I advised against unsupervised cutting and jumping, that I offered the criteria, and what I did program. I do not silently proceed with a sport-specific program to keep the client happy, because that would put her knee and my professional standing at risk.
