13. ACL Injuries
Most MOI are non-contact
rotational forces
Tibia displaced anteriorly on
femur (or vice versa), rotational
stress (cutting) or
hyperextension
May be isolated, but typically
due to MOI, other structures
(joint capsule, menisci) also
injured
Positive anterior drawer and/or
Lachman’s tests
14. PCL Injuries
Most common MOI is fall on flexed knee driving tibia
posterior on femur
May also occur with rotational and/or hyperextension MOI
Often treated non-operatively as quadriceps muscles are
able to minimize posterior displacement of tibia on femur
Positive posterior drawer and/or posterior sag tests
15. MCL Injuries
Most common MOI is
blow to lateral knee with
resulting valgus tension
forces
May also be injured by
non-contact and/or
rotational stresses
Positive valgus stress test
16. LCL Injuries
Most common MOI is
blow to medial knee
with resulting varus
tension forces
Internal rotation of tibia
may be secondary
contributor to LCL injury
Positive varus stress test
17. Meniscal Injuries
May be isolated from
flexion/hyperflexion with
rotation of the knee – “pinched”
between tibia and femur
Often injured in association
with cruciate ligament injury
“Classic” symptoms include
joint line pain and clicking or
locking – helpful but not
definitive evaluative tools
Limited reliability of special
tests

After ACL tear, need surgical intervention if planning on returning to competitive/recreational activity. Not for other injuries really, the ACL is he primary knee stabalizer
Stronger quads can help in prevention
