A Novel Achilles Tendon Repair Technique Utilizing a Bio-Composite Scaffold for a Sub-Acute Tear.

Abstract

Achilles tendon ruptures are prevalent musculoskeletal injuries accounting for 20% of all large tendon ruptures with a re-rupture rate of 2.1-8.8%. Ineffectual management of these injuries can lead to a significant loss in push-off strength and overall ankle function. The field of orthopedic surgery has shown an increasing interest in biologic augmentation. Encouraged by its success in various other applications, this approach holds promise for potentially enhancing outcomes in Achilles tendon repairs, especially in poor tendon tissue. The BioBrace® (ConMed, New Haven, Connecticut) is a biocomposite scaffold made of highly porous type I collagen and bioresorbable poly (L-Lactide) (PLLA) microfilaments. It can be applied in conjunction with Achilles tendon repair or reconstruction. It provides immediate strength to the augmented repair upon implantation and simultaneously promotes new, organized tissue growth throughout its resorptive phase. Here, we outline a technique to effectively augment an acute Achilles tendon repair utilizing the BioBrace® reinforced bio-inductive implant.
