Technique for all arthroscopic Brostrom repair using novel biocomposite scaffold ligament graft

Abstract

Ankle sprains affect a large portion of the general population and are one of the most common reasons for emergency room visits in the United States and globally. In recent years the advent of synthetic ligament grafts has provided an option for repair of the diseased/injured ligament using an anatomic augmentation. Several of these ligament grafts exist, however long-term data is limited. There has been no report in literature of an all-arthroscopic technique with use of biocomposite scaffold ligament graft in repair of the lateral collateral ankle ligaments. Technique and case examples are described using an all-arthroscopic technique for anatomic lateral ankle ligament repair using a novel ligament graft. Five patients with refractory chronic ankle instability received all arthroscopic ATFL repair using the biocomposite scaffold ligament graft. Pre and post operative American orthopedic foot and ankle society score, foot function index score, visual analog pain scale scores were collected. Mean pre-operative American orthopedic foot and ankle society score, foot function index score, visual analog pain scale were 38.2 ± 22.7, 55.28 ± 29.8, 6.8 ± 2.2 respectively. Mean post-operative American orthopedic foot and ankle society score, foot function index score, visual analog pain scale were 88.0 ± 11.4, 16.4 ± 14.0, 1.6 ± 1.5 resp. This technique offers anatomic restoration of the lateral ankle ligamentous complex through a minimally invasive approach that can lead to quicker recovery and return to activity.
