ACL Prehabilitation Programme: 6-Week Evidence-Based Guide
An ACL prehabilitation programme is a structured 4 to 6-week physiotherapy protocol delivered before ACL reconstruction surgery, designed to restore knee range of motion, quadriceps strength, and neuromuscular control to at least 90 percent of the uninjured side before the scalpel touches skin. Landmark randomised controlled trials from the Delaware-Oslo group demonstrate that a completed ACL prehab programme cuts post-operative recovery by 4 to 6 weeks and improves 2-year IKDC subjective scores by 12 points. In Bengaluru \u2014 where over 3,000 ACL reconstructions are performed annually at Fortis, Apollo, Manipal and Sagar Hospitals \u2014 prehab remains under-utilised. This clinical guide walks you through the evidence, the 3-phase 6-week programme, objective clearance benchmarks, and how our senior clinicians at JP Nagar deliver it.
1. Why the ACL prehabilitation programme matters
The anterior cruciate ligament is the most commonly injured knee ligament in pivoting sports \u2014 football, basketball, badminton, kabaddi \u2014 and Bengaluru sees the second-highest volume of ACL reconstructions in urban India. The traditional model of \u201cinjury \u2192 surgery in 3 weeks \u2192 physio\u201d is losing evidential ground. Every additional 1 % of quadriceps strength deficit at surgery translates to 0.7 % strength deficit at 12 months post-op. An ACL prehabilitation programme systematically reverses this deficit before the surgical trauma is even added.
2. Programme goals & pre-surgery benchmarks
| Metric | Target | Assessment tool | Why it matters |
|---|---|---|---|
| Effusion | None or trace (stroke test grade 0) | Sterling stroke test | Effusion inhibits quadriceps activation |
| Knee extension range | Full (equal to unaffected side) | Goniometer, prone hang | Extension deficit predicts arthrofibrosis |
| Knee flexion range | ≥ 125° | Goniometer | Needed for gait, stairs post-op |
| Quadriceps LSI | ≥ 90 % | Isokinetic, hand-held dynamometer | Strongest predictor of 12-mo outcome |
| Single-leg squat | 10 reps pain-free | Observation | Neuromuscular control baseline |
| Y-balance test composite | ≥ 90 % of unaffected | Y-Balance Kit | Predicts non-contact re-injury risk |
3. Weeks 1\u20132 \u2014 pain, swelling & range of motion
- Cryotherapy \u2014 15 min ice, 4\u00d7 daily. Compression sleeve for 22 hrs/day.

- Quadriceps sets + straight-leg raise \u2014 3 sets \u00d7 10 reps hourly during waking hours.
- Electrical stimulation (NMES) \u2014 20 min, 5 days/week to bypass arthrogenic muscle inhibition.
- Patella mobilisation \u2014 4-quadrant patellar glides to prevent adhesions.
4. Weeks 3\u20134 \u2014 strength building
- Closed-chain squats \u2014 0\u201360\u00b0 range, 3 sets \u00d7 15 reps, progressing from bodyweight to 10 kg dumbbells.
- Leg press \u2014 double-leg then single-leg, 3 sets \u00d7 12 reps at 60 % 1RM.
- Hamstring curls \u2014 3 sets \u00d7 15 reps, seated or prone.
- Calf raises \u2014 3 sets \u00d7 20 reps double-leg progressing to single.
- Stationary bike \u2014 20 min/day, resistance level 4\u20136.
- Aquatic therapy \u2014 chest-deep walking, 20 min, 3 days/week if pool available.
5. Weeks 5\u20136 \u2014 neuromuscular control & sport-specific
- Single-leg squat \u2014 4 sets \u00d7 10 reps with knee-over-toe alignment.
- Lateral step-downs \u2014 4 sets \u00d7 10 reps from 20 cm step.
- Perturbation training \u2014 tilt board single-leg stance, 3 \u00d7 30 s.
- Y-balance drills \u2014 3 sets in 3 planes.
- Straight-line jogging (if effusion resolved) \u2014 5 min \u2192 20 min progression.
- Patient education session \u2014 review of post-op day-1 to day-14 exercises, brace use, weight-bearing progression.
6. Objective clearance grid \u2014 ready for surgery?
| Test | Green light | Yellow — extend prehab | Red — postpone surgery |
|---|---|---|---|
| Effusion | None | Trace | Grade 2+ |
| Knee extension | 0° | 2° deficit | ≥ 5° deficit |
| Knee flexion | ≥ 125° | 120–125° | < 120° |
| Quad LSI | ≥ 90 % | 80–89 % | < 80 % |
| Single-leg squat | 10 pain-free | 5–9 | < 5 or painful |
| Y-balance | ≥ 90 % | 80–89 % | < 80 % |
7. Evidence base & clinical outcomes
- Failla MJ et al. (Am J Sports Med, 2016) \u2014 Delaware-Oslo RCT: prehab reduces post-op strength deficit by 15 %.
- JOSPT (2017 CPG) \u2014 clinical practice guideline: grade A recommendation for structured prehab.
- BJSM (2020) \u2014 meta-analysis: 12-point IKDC improvement at 2 years favouring prehab.
