This document presents the case of a 22-year-old Thai man who injured his right knee playing football. His physical examination revealed swelling, pain on motion, and a positive anterior drawer test of the right knee. An MRI confirmed a complete tear of the anterior cruciate ligament and a tear of the medial meniscus.

 Rt knee injury in football match with anterior drawer
test positive

11. Differential Diagnosis
 Knee ligamentous injury
 Fracture

12. Ligamentous Injuries
 ACL injuries
 PCL injuries
 MCL injuries
 LCL injuries

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

18. Investigation
 X-ray
 MRI

19. X-ray

24. Grading ligamentous injury
 Grade 1 : Ligament
Swelling, localized tenderness
 Grade 2 : Ligament stretching partial tear
