Pes Anserinus Structural Framework and Constituting Tendons Are Grossly Aberrant in Nigerian Population

Figure 3

(a) Photograph and (b) schematic illustration showing painted type III pes anserinus formed by sartorius, gracilis, and semitendinosus tendons and an accessory semitendinosus tendon gracilis and semitendinosus. Each constituting tendon attached as separate entity on the tibia. Hence, this pes anserinus type is said to exhibit the nonconvergence (side-by-side termination) pattern based on the union of constituting tendons classification of pes anserinus. DT: dissection tool; SA: sartorius muscle; SAT: sartorius tendon; GRT: gracilis tendon; STT: semitendinosus tendon; aSTT: accessory semitendinosus tendon; orange arrow indicates level of tibial tuberosity; P: patella; blue arrow indicates the inferior attachment of pes anserinus.
