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

3. 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

4. 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]

5. Objective
to provide an anatomical description of the anterolateral ligament of the knee (ALL) and describe its clinical correlations

6. 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

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

9. 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

10. Results
Measurements
Length(mm) 38
Width(mm) 7
Thickness(mm) 3

11. 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

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