Knee Injury Prevention: Evidence-Based Strategies for Athletes & Active Adults

Knee injuries (ACL, meniscus, PFPS, tendinopathy) are preventable with structured programs.

1. Neuromuscular Training (Strongest Evidence)

• FIFA 11+, PEP Program, KIPP — 20–30 min, 2–3×/week.
• Components: plyometrics, balance, strength, agility, landing mechanics.
• Reduces ACL injury 50–70% in females.

2. Strength Foundations

• Quadriceps (VMO focus), hamstrings (eccentric), gluteus medius/maximus, hip external rotators, core.
• Exercises: Single-leg RDL, Bulgarian split squat, Nordic hamstring, clamshells, Copenhagen planks.

3. Movement Quality

• Valgus collapse prevention (knee over 2nd toe).
• Soft landing (toe-heel, knee flexion > 30°).
• Deceleration control.

4. Load Management

• Acute:chronic workload ratio < 1.3.
• Periodization: deload weeks, off-season.
• Surface progression (grass → turf → court).

5. Equipment & Environment

• Sport-specific shoes (replace q300–500 mi).
• Bracing: Prophylactic braces lack evidence; functional braces post-ACLR may help.

6. Recovery

• Sleep 8–10 hrs (injury risk ↑ 1.7× if < 8 hrs).
• Nutrition: protein 1.6–2.2 g/kg, vitamin D, omega-3.
• Modalities: foam rolling, compression, contrast therapy (individual response).

Sample Daily Knee Prehab (10 min)

1. Glute bridges 2×15.
2. Side-lying clams 2×15/side.
3. Single-leg balance 30 sec/side (progress: eyes closed, foam).
4. Eccentric step-downs 2×10/leg.
5. Copenhagen adduction 2×10/side.

Consistency > intensity. Screen movement (Landing Error Scoring System) annually.
