Hip Surgeon-to-Surgeon Course, Herentals, 2025
In October 2025, Dr Mametja attended a dedicated Hip Surgeon-to-Surgeon Course at AZ St.
Elisabeth Herentals Hospital in Herentals, Belgium. The programme focused on hip replacement using the Direct Anterior Approach.
The structured programme included multiple live hip replacement procedures, case presentations and case-based discussions with teaching surgeons Dr Lieven Vermuyten and Dr Mike Tengrootenhuysen.
This visit formed part of Dr Mametja’s continued development in contemporary anterior hip replacement surgery and broadened his exposure to different operative techniques, workflows and surgical approaches within the Direct Anterior Approach.

Hip and Knee Joint Replacement Observership, 2025
In November 2025, Dr Mametja undertook an international surgical observership programme in Graz and Vienna, Austria, followed by a professional visit to Medacta’s international headquarters in Rancate, Switzerland.
In Graz, he attended knee replacement surgeries with Professor Patrick Sadoghi at the University Clinic Graz, gaining further exposure to contemporary knee replacement techniques and surgical workflows.
The programme then continued in Vienna at the Orthopaedic Hospital Vienna-Speising, where Dr Mametja attended anterior hip replacement surgeries with Associate Professor Jochen Hofstätter, whose clinical work includes primary and revision hip and knee replacement.
The visit concluded with a professional visit to Medacta’s international headquarters in Switzerland, which included a company and factory visit and an overview of orthopaedic implant development and manufacturing.
Together, these international visits have contributed to Dr Mametja’s ongoing professional development in modern hip and knee joint replacement surgery, with continued exposure to contemporary approaches in both primary and revision joint replacement.
