Dr Vardi graduated with an MBChB from the University of Pretoria and then completed his Fellowship from the College of Orthopaedic Surgeons of South Africa through the University of Cape Town.

Dr Vardi did two fellowships in knee surgery at the University of Nottingham, Queen’s Medical Centre, UK, in 1995 and 1996. He then joined the Droitwich and London Knee Clinics, where he acted as a consultant and in-house faculty member as a knee surgeon from 1997 to 2005.

Upon returning to Johannesburg in April 2005, he started a private knee surgery practice at the Rosebank Hospital and the Centre for Sports Medicine and Orthopaedics in Rosebank.

Dr Vardi is responsible for running a private clinical knee surgery fellowship, which enables junior orthopaedic colleagues to assist him in his practice and learn techniques of knee surgery and the clinical management of private practice. In addition to this, Dr Vardi acts as a consultant for Smith and Nephew, where he teaches and runs courses. As a result, he is instrumental in teaching surgical techniques to visiting surgical practitioners (VSPs). He is an honorary lecturer at Wits Initiative for Sports Health, the School of Clinical Medicine and the faculty of Health Sciences at the University of Witwatersrand.
