Since 2013, the ORACO unit has been operational under the direction of Dr. Michele Ulivi. Within this operating unit, primary hip and knee prosthetic surgery and prosthetic revision surgery is performed. The unit also carries out activities in the field of arthroscopic knee surgery. Computer-assisted hip and knee surgery and robotic surgery are also performed.

The operating unit is also strongly involved in research activities within the Galeazzi Orthopaedic Institute. In particular, Dr. Michele Ulivi has been appointed P.I. of the prosthetic register of the Galeazzi Institute.

Clinical research activities are carried out in the field of hip and knee prosthetic surgery, evaluating through the register the outcome of patients following new surgical procedures or new care protocols.

The development of the prosthetic registry is also carried on through updating with new PROMs questionnaires and with the development of techniques for the remote control of patients. The operating unit also carries out research in the field of 3D Model Based Radiostereometry for the study of micro-movements of knee and hip prosthetic implants.
