During his career as an anatomist and further development as a surgeon, Dr. Gelber has gained extensive knowledge in this field. It gives him a unique expertise when assessing injuries and reconstructing them as closely as possible to their prior natural state. The precise location of the tunnels is the most important aspect of ACL surgery. It is so much so that placement only millimeters off their optimum position is the main cause of ACL reconstruction failure.
In this context, ACL surgery has evolved dramatically in recent years. Not long ago and even in many places still today, the ligament is reconstructed with a central upright graft. This has led to continued rotational instability, which is most disabling and harmful to the patient. It has been shown that the best way to reconstruct the ligament is by reproducing its previous anatomy as this best restores its proper function in comparison to these previous techniques. Dr. Gelber, as part of the Equilae team has been a pioneer in Spain in the introduction of this technique and its variants of selective or partial ligament reconstruction. There are multiple scientific studies that Dr. Gelber has contributed to in this field of surgery.
