Abstract
Surgical treatment of posterior cruciate ligament injuries is gaining more and more importance. The central posterior approach according to Abbott (1945) has been considered a standard, with various complications involved owing to the local anatomic conditions. This study is intended to present a modified dorsomedial approach to the posterior capsule of the knee joint that is better adapted to the anatomic conditions. As a basis, the popliteal region was dissected in 150 knee joints, and the course of the popliteal artery with its branches as well as the bifurcation of the sciatic nerve were identified. The medial joint line served as a reference point. It has been shown that the knee joint arteries and the two sural arteries arose at relatively constant levels. At least one of the meniscofemoral ligaments was found in all of the knee joints examined the anterior ligament was present in a slightly higher percentage than the posterior ligament. The modified dorsomedial approach to the posterior joint capsule was evaluated in 50 knee joints. Dissection was achieved by blunt division of the medial head of the gastrocnemius muscle, with careful preservation of the proximal vascular supply of that muscle. It was necessary to expose neither the popliteal artery and vein nor the tibial nerve. The tibial attachment of the posterior cruciate ligament could be exposed in every knee. The advantage of the new approach to the posterior cruciate ligament described in this study consists in the preservation of the central neurovascular bundle and the excellent exposure of the tibial attachment.
