Dr Bogdan Ambrožič received his medical degree from the Faculty of Medicine at the University of Ljubljana, Slovenia, in 1995 and he finished his residency in orthopaedics in 2001.

In 2009, he received a master’s degree in medical science and in 2017 he finished the PhD, analysing the influence of medial patellofemoral ligament (MPFL) on patellar stability.

His practice is based on arthroscopic and minimally invasive surgical treatments of injuries and diseases of the shoulder, knee joint and ankle, also through the use of computer technology.

In the shoulder joint, he most often intervenes in arthroscopic stabilization of the joint and in the reconstruction of the rotator cuff. In the case of the knee joint, he performs meniscus and cartilage repair, reconstruction of ligaments, including multi-ligament injuris and osteotomies around the knee. In these procedures, he uses navigation and 3D printed guides for each patient’s and its individual anatomy.  In addition, he performs stabilization of the patella by reconstructing the MPFL, the transposition of the tibial tuberosity and trochleoplasty. In the ankle, in addition to normal arthroscopic procedures, he performs arthroscopic stabilization of the joint and tendinoscopies.

In addition, he uses biological methods for treating damaged joints and tendinopathies with thrombocyte plasma (PRP), stem cells and amniotic membranes.

In Slovenia, he introduced the method of stabilising the patella with the reconstruction of the medial patellofemoral ligament (MPFL), the method of reconstructing the anterolateral ligament (ALL) and he performed the first meniscus transplantation. He also started performing osteotomies in the knee joint by means of navigation and patient specific guides. He organized numerous arthroscopic symposia and workshops, and he is visiting lecturer at conferences and symposiums in Slovenia and abroad. He is a member of the European Committee for Osteotomy, and an active member of the Slovenian Association for arthroscopy and sports injuries.
