ACL Prevention

매 한 줄

"매 ACL 부상 prevention 의 핵심 = neuromuscular training + landing mechanics + proprioception.". ACL (Anterior Cruciate Ligament) tear 의 70% 는 non-contact pivoting/landing 상황에서 발생하며, FIFA 11+, PEP, KIPP 같은 evidence-based program 이 incidence 를 50-70% 감소시킨다.

매 핵심

매 Risk Factor

• Modifiable: knee valgus on landing, weak hip abductors, quad-dominant deceleration, fatigue.
• Non-modifiable: female sex (2-8x risk), narrow intercondylar notch, generalized joint laxity.
• Environmental: cleat-surface interaction, fatigue late in match, prior injury history.

매 Prevention Pillar

• Neuromuscular training — plyometric + balance + strength, 2-3x/week.
• Landing mechanics — soft landing, knee over toe, hip-dominant.
• Core/hip strength — gluteus medius, hip external rotators.
• Proprioception — single-leg balance, perturbation training.

매 응용

1. Youth soccer FIFA 11+ warmup (15 min pre-training).
2. Female collegiate athletes PEP program.
3. Post-ACLR return-to-sport batteries.

Risk Score Aggregator

import pandas as pd

    """0-1 risk; >0.6 → enroll in prevention program."""
    score = 0.0
    if athlete["sex"] == "F": score += 0.25
    if athlete["prior_acl"]: score += 0.30
    if athlete["knee_valgus_deg"] > 8: score += 0.20
    if athlete["hop_lsi"] < 0.85: score += 0.15  # limb symmetry
    if athlete["age"] < 18: score += 0.10

매 결정 기준

상황	Approach
Youth team, no history	FIFA 11+
Female collegiate	PEP / KIPP
Post-ACLR	Criterion-based RTS battery
Pro athlete in-season	Modified neuromuscular maintenance

기본값: FIFA 11+ 2-3x/week.

언제: structured risk-stratification, program selection, periodization advice. 언제 X: clinical diagnosis, surgical decision, individualized rehab prescription.

❌ 안티패턴

• Static stretching only: 매 효과 없음. Dynamic warmup 필요.
• Knee-only focus: hip/core ignore 시 valgus 재발.
• Volume without quality: poor landing form 의 reps 는 risk 증가.
• Generic program: sex/age/sport-specific tailoring 없으면 effect size 감소.

🧪 검증 / 중복

• Verified (Hewett 2005, Sadoghi 2012 meta-analysis, FIFA 11+ RCT).
• 신뢰도 A.
