What are the 3 layers of the Medial Support Complex? -
ANSWER-1. Superficial
- sartorius and fascia
2. Middle
- contains superficial MCL and semimembranosus (hamstring
muscle group)
3. Deep
- contains deep fibres of MCL and capsule
What does the stability of a Medial Support Complex look like? -
ANSWER-- MCL primary stabilizer does most of its work at 25-30
degrees of flexion
-- ACL/PCL secondary vs. Valgus
- Muscles help in full extension
-- medial hamstrings (sartorius, semimembranosus +
semitendinosus_
,2|Page
-- medial head of gastrocs.
-- quad muscle (vastus med.)
- Bony structure is tertiary support
-- bony support in full extension
What is the MCL? - ANSWER-- broad unlike the LCL
-- narrow and extracapsular
- A capsular ligament (swells)
-- thick capsular effusion in 8 hours
- Has superficial and deep components
-- deep portions connect directly to the medial meniscus
-- superficial portions run from medial femoral epicondyle to
superomedial surface of tibia
Knee flexion and extension (medial view) - ANSWER-- Most
active resisting valgus loading when knee is 25-30 degrees of
flexion
- each part loaded at varying angles
- the wider the ligament turns, the more its on stretch
,3|Page
-- treat them the same anyways (not a lot of space but good to
know there are 2 parts)
At 5 degrees of flexion what happens? - ANSWER-- Superficial =
57%
- Deep = 8%
- Posterior Oblique = 18%
At 25 degrees of flexion what happens? - ANSWER-- Superficial
= 78%
- Deep = 4%
- Posterior Oblique = 4%
Contribution by structure of Medial Knee Injuries at 25 degrees -
ANSWER-- Superficial MCL = 78%
- Cruciates = 13%
- Deep MCL = 4%
- Posterior Capsule = 4%
, 4|Page
Contribution by structure of Medial Knee Injuries at 0-5 degrees -
ANSWER-- Superficial MCL = 57%
- Cruciates = 15%
- Deep MCL = 8%
- Posterior Capsule = 18%
What should you check when there is significant MCL injury? -
ANSWER-ALWAYS CHECK THE PCL AND ACL because they
are the 2nd line of support against that mechanism
Describe what happens during a retrocalcaneal bursitis -
ANSWER--
Anatomy of the ACL - ANSWER-- Runs from the ant. Aspect of
tibial plateau to post. Medial aspect of lateral femoral condyle
- primary restrain to ant. Tibial ext.
- greatest translation occurs at 20-30 degrees
What are the 2 major bundles that are named for their attachment
on the tibia (ACL)? - ANSWER-- Anteromedial -- tighter in flexion
