Study Notes
Lachman's Test
- Study by DeCary et al. in 2017, used data from systematic reviews of ACL injuries (6 studies) and knee osteoarthritis (multiple studies)
- Found sensitivity to be 94%
- Limitations include patient relaxation, muscle guarding, and body habits; if the hamstring are contracting it will affect the test
Anterior Drawer Test
- Study by DeCary et al. in 2017, used data from systematic reviews of meniscal injuries (28 studies), ACL injuries (28 studies), Ottawa knee rule fractures (multiple studies), and knee osteoarthritis (multiple studies)
- Found sensitivity to be 85%
- Limitations include patient relaxation, muscle guarding, and body habits; if the hamstring are contracting it will affect the test
ACL Anatomy
- Originates from the posterior aspect of the lateral femoral condyle and inserts onto the anterior intercondylar area of the tibia
