Return-to-Sport Decision After ACL Reconstruction With a Fearful Patient
Ms. Nakamura is a 22-year-old competitive soccer player 7 months after anterior cruciate ligament reconstruction using a hamstring graft. She has completed formal rehabilitation, has full range of motion, and quadriceps strength is 85% of the uninvolved side. However, she reports fear of re-injury and hesitates during cutting and jumping tasks. Her surgeon has cleared her for return to sport "when ready." The therapist must decide whether to clear her for full competition or to continue rehabilitation.
1. What criteria should guide the return-to-sport decision, and how does psychological readiness factor in?
Read the worked answer
Criteria:
- Strength: quadriceps and hamstring limb symmetry index typically ≥90%.
- Hop tests: single-leg hop, triple hop, crossover hop, and timed hop with limb symmetry ≥90% and good quality of movement.
- Agility and cutting tasks without hesitation or giving-way.
- Full range of motion and no effusion.
- Psychological readiness: fear of re-injury is a known risk factor for re-injury and poor performance. Use a validated measure such as the ACL-RSI.
Decision: She does not meet strength criteria (85%) and shows fear and hesitation. Clearing her now would be premature. Continue rehabilitation with a focus on strength, plyometrics, and graded exposure to cutting and jumping, and address psychological readiness through confidence-building and education. Reassess in 4–6 weeks.
2. Design a 4-week program to address her deficits and fear.

Program:
- Strength: progressive quadriceps and hamstring loading, including eccentric hamstring exercises and single-leg squats.
- Plyometrics: double-leg to single-leg hops, lateral hops, and bounding, progressing from low to high intensity.
- Agility: cone drills, deceleration, and change-of-direction at gradually increasing speed.
- Sport-specific: cutting and ball drills in a controlled environment.
- Psychological: graded exposure, goal setting, and education about re-injury risk; consider referral to a sports psychologist.
- Monitoring: weekly hop tests and strength measures; watch for effusion and pain.
Progression criteria: advance only when the patient completes tasks with confidence and good mechanics.
3. At the 4-week reassessment she is stronger but still fearful. How do you communicate the decision to her and her coach?
Read the worked answer
Communication:
- Be honest and specific: she has made progress but does not yet meet the criteria for full competition.
- Explain the evidence linking fear and strength deficits to re-injury risk.
- Offer a clear plan and timeline, and involve the coach in a modified training plan (e.g., limited minutes, non-contact drills).
- Set measurable goals for the next phase.
- Document the decision and rationale.
Ethical framing: Respect her autonomy and desire to play while upholding safety and the duty to provide evidence-based advice. Avoid clearing her under pressure from the coach or player.
