Fibrous tissue continuous from some structures. a Lateral aspect of the right knee. b–d Horizontal slices at lines (B), (C), and (D) in a. However, these slices are different from the sample of a. e–g Sections stained with Masson’s trichrome on rectangles in b, c, and d. e The range of the Gerdy’s tubercle (GT) is shown by a double arrow. The fascia lata (green arrowheads) and a fibrous tissue (yellow arrowheads) continuous from the fabellofibular ligament (FF) were attached to the lateroposterior area to the GT. f A fibrous tissue (pink arrowheads) was observed under the biceps femoris (BF). It was mingled with the fascia lata (green arrowheads). The fibrous tissue (yellow arrowheads) continuous from the FF adhered to the joint capsule or the lateral meniscus (LM). g A fibrous tissue (reddish purple arrowheads) continuous from the tendon (purple arrowhead) of the gastrocnemius (Ga) was observed. It was mingled with the joint capsule (Cap). FC fibular collateral ligament, Fe femur, IT iliotibial tract, LE lateral epicondyle, Pa patella, Ti tibia, Med medial, Pos posterior, Pro proximal
