The popliteal region presents a wide range of vascular anomalies. The correct diagnosis of these anatomical variations plays a key role in success of diverse procedures performed by orthopaedicians, vascular surgeons and radiologists. In this context, the aim of our study was to gain knowledge on the origin, level and mode of termination, course and relations of popliteal artery with surrounding structures, mainly the muscles, in popliteal fossa. The results obtained were compared with previous studies. Materials and methods: The study was carried out in 50 lower limbs of 25 well-embalmed cadavers. There was no evidence of previous knee surgeries in any of the limbs. The specimens were collected from the department of Anatomy, KVG Medical College, Sullia. Results: The femoral artery continued as popliteal artery, which terminated at the lower border of popliteus muscle. Trifurcation pattern was observed in one specimen. 10% of specimens had hypoplastic/aplastic posteriortibial artery, distally replaced by peroneal artery. Another 4% of specimens had smaller posterior tibial and larger peroneal artery. Length of tibio peroneal trunk from the lower border of popliteus muscle was shorter than normal (2.5 cm) in one specimen and longer in another specimen. The observation on course and relations showed that the popliteal artery passed beneath a bony tunnel of fibula before terminating in one specimen and in another specimen, popliteal artery was superficial to popliteal vein in the middle of popliteal fossa. In other two specimens, it coursed more medially towards medial head of gastrocnemius and another specimen presented with popliteal artery crossed by muscle belly of plantaris. Conclusion: This study adds up to the knowledge on vascular variations in the popliteal region, the awareness of which is important to vascular surgeons while performing arterial reconstructions in femoro distal bypass graft procedures and also to orthopaedicians during surgical clubfoot release.
