Figure 1

Dissection process of the ALL. (a) After removal of the skin and subcutaneous tissue, (b) after the ITT is separated posteriorly from the vastus lateralis, the Kaplan fibres and capsulo-osseous layer (Black arrow head) become evident, and (c) after the ITT including the capsulo-osseous layer is reflexed to Gerdy’s tubercle, the ALL is visible within the level of the Seebacher Layer 3. ALL: anterolateral ligament, BF: biceps femoris, GT: Gerdy’s tubercle, ITT: iliotibial tract, JC: joint capsule, KF: Kaplan fibres, LCL: lateral collateral ligament, LFE: lateral femoral epicondyle, LM: lateral meniscus, and PT: popliteus tendon.
