About this trial

The purpose of Total Knee Replacement (TKR) is to remove worn cartilage surfaces and replace them with artificial parts of the same shape. TKR can be used in cases of osteoarthritis, inflammatory rheumatism, bone necrosis of the knee or following malformative or traumatic sequelae.

Implant alignment is paramount in TKR and the last years have seen a proliferation of alignment techniques following the introduction of computer and robotic-assisted surgery. Among Computer-assisted surgery, the augmented reality-based navigation system can be an option to improve accuracy in orthopaedic surgery.

The hypothesis of this study is: the use of augmented reality-based navigation system allows a prosthesis alignment and positioning that is at least as good as with the traditional mechanically aligned technique, and therefore improves knee functional results. This study also aims at assessing the cost-effectiveness of this new technology.
