ACL Tear in Under 3 Minutes: NPTE Cheat Sheet
Update: 2025-11-22
Description
ACL Tear — NPTE Cheat Sheet
- What it is:
- ACL failure from excessive anterior tibial translation — basically the tibia tries to run off and the ACL can’t hold the line.
- Classic signs:
- Pop
- Immediate swelling (1–2 hours)
- Pivot / cutting mechanism
- Instability
- Difficulty weight-bearing
- Rule-in test:
- Lachman test — NPTE’s #1.
- Rule-out clues:
- Slow swelling → Meniscus
- Posterior sag → PCL
- Medial pain → MCL
- NPTE trap:
- Delayed swelling means NOT ACL.
- Best treatment:
- Early ROM, quads, swelling control, gait normalized.
- Mock question included: Yes — test yourself before you move on.
