History
• 1879-Paul Segond: “pearly, resistant, fibrous band”[1]
(mid-third) lateral capsular ligament
Capsulo-osseous layer of the iliotibial band
Anterolateral ligament

Anatomy• The anterolateral ligament (ALL) is located on
the lateral region of the knee, anterior to the lateral collateral ligament (LCL) and posterior to Gerdy’s tubercle.
• Origin: lateral epicondyle[1] or condyle[2] of the femur• Insertion: anterolateral aspect of the proximal tibia, with 2 attachements

Background
• common procedure of orthopedics surgery : ACL reconstruction
• even after reconstruction,some patients experience tough anterolateral rotatory movement (pivot shifting)[1],[3]
• role of ALL : seems to stabilize medial rotation of the knee[1],[3]

Objective
• to provide an anatomical description of the anterolateral ligament of the knee (ALL) and describe its clinical correlations
![Page 6: Anatomy of the knee The anterolateral ligament (ALL) Author : Radu Branea Co-author : Feier Andrei, Al Hussein Hussam, Tăbăcar Mircea Scientific coordonator.](https://reader036.fdocuments.us/reader036/viewer/2022081501/56649ec15503460f94bcca74/html5/thumbnails/6.jpg)
Material and method
• Eight paired cadaveric knees belonging to the Anatomy Department
• One amputated lower limb from the Pathology Department
• dissected in the anterolateral region;
• The ALL was clearly observable

What we foundITB=Iliotibial Band
GT=Gerdy’s Tubercle
LFE=Lateral Femoral Epicondyle
LCL=Lateral Collateral Ligament
FH=Fibular Head

Results
• Origin: Lateral Femoral Epicondyle(LFE)
• Insertion: 1.proximal tibia, between Gerdy’s tubercle(GT) and fibular head(FH); 2. Lateral meniscus
• Closely related to the LCL, however independent

Conclusions
• Formerly known as only a fascia, the ALL could now prove to be a lot more than that
• Possible involvement in ACL(Anterior Cruciate Ligament) related sports injuries

Discussions
• Pros: - new subject - emphasize the existence of the ALL
- starting point for detailed orthopaedic studies
• Cons: - ethics - small number of dissections
