Arthroscopic anterior cruciate ligament reconstruction in a patient with multiple hereditary exostoses.

Acta Biomed 2021 Jul 26;92(S3):e2021004. Epub 2021 Jul 26.

San Pier Damiano Hospital - Faenza (RA).

Background Multiple hereditary exostoses (MHE) also known as Multiple Osteochondromas is a rare benign bone tumour disease, characterized by multiple osteocartilaginous masses. The knee is one of the most affected sites. Anterior cruciate ligament (ACL) surgery is the most common and generally most successful surgical knee procedure; however, the association between MHE and ACL reconstruction is very rare and may represent a challenging procedure because of the anatomical anomaly related to presence of multiple masses around the knee.

Authors:
Jinzhong Zhao

Arthrosc Tech 2021 Jun 24;10(6):e1609-e1613. Epub 2021 May 24.

Department of Sports Medicine, Shanghai Sixth People's Hospital, Shanghai Jiao Tong University, Shanghai, China.

In anterior cruciate ligament (ACL) reconstruction, fixation of the graft with hardware is a routine procedure. However, in some cases when the hardware is not intended to be used or is unavailable, ACL reconstruction with hardware-free fixation must be the treatment of choice. We introduce a single-bundle anatomical hardware-free ACL reconstruction technique in which a set of Y-shaped femoral tunnels is created for the fixation of the proximal end of the graft over the bone bridge between the 2 outer orifices, and a transtibial ridge tunnel is created to set a suture loop with a knot for the fixation of the distal end of the graft at the suture loop.
