Public activity

• Member of Lithuanian Society of Orthopaedists Traumatologists
• Full member of European Society of Society of Sports Traumatology, Knee Surgery & Arthroscopy (ESSKA) and International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine (ISAKOS)

I have been associated with the Carolina Medical Center clinic since 2009 - initially as part of the Student Science Club, then I completed a specialization training as part of my residency. 

I am a member of the Polish Orthopedic and Traumatological Society, the Polish Arthroscopic Society, the Polish Society of Hand Surgery and the European Society of Sports Traumatology, Knee Surgery and Arthroscopy

The main area of my interest is sports traumatology – treatment of fractures and reconstruction of damaged tendons or ligaments; arthroscopic surgery – especially knee and wrist surgery and hand surgery – including procedures using the WALANT method (Wide-awake Local Anesthesia No Tourniquet). 

In the postoperative period, I stay in touch with the patient in order to ensure the most optimal way of recovery – through supervision of rehabilitation and regular check-ups. In my work, I attach great importance to comprehensive treatment that focuses not only on the structural problem, but also takes into account the patient’s chronic diseases, dietary management and lifestyle changes.

15,000 operations and 1215 hip arthroscopies between 2009 and 2015.

Many Italian and international professional athletes have been treated by Dr Zini over the years: Sasha Djordjevic, Jean Prioleau, Alex Kaluzhny, Carolina Costagrande…

Since 2007 he has been Coordinator of the Operative Unit of Orthopedics and Traumatology at Maria Cecilia Hospital and Scientific Supervisor of the Orthopedic Area of GVM Care & Research, where every year more than 1,200 cases are treated by his team of orthopedists.

He operates in the field of diagnosis and therapeutic treatment of degenerative diseases and traumatic diseases of the knee, hip, shoulder, ankle, foot, hand, spine; in the arthroscopic treatment of the wrist, hip, knee and shoulder and in major prosthetic surgery for the knee, hip, shoulder, as well as in orthopedic and physiatric rehabilitation. In particular, he specializes in the treatment of the following pathologies: femoro-acetabular impingement, pubalgia, chondropathy, Perthes disease, synovitis and the snapping hip syndrome. 

Author of 7 monographs of over 100 publications in national scientific journals.

 Among the most recent publications: "Thirty years of Arthroscopy in Italy" 2011 Argalia Publishing and "Groin Pain Syndrome" 2017 Publishing Springer-Verlag. He is the author of over 200 reports on Hip, Knee, Ankle, Shoulder Prosthetics, Hip, Ankle, Knee, Elbow, Wrist, Shoulder Arthroscopy, BioTechnology, Sports Traumatology.

He was awarded twice with the Bellando-Randone Prize of the Italian Society of Orthopedics and Traumatologists (SIOT) for the best monograph of the year 1983 with the book "Radiculography Lombare - Text Atlas", Editrice Roma; and for the best monograph of the 1997 with the volume "Arthroscopy of the ankle - Practical manual of surgical technique" Editrice Fortuna.
