Abstract:
Ligament and tendon ruptures have historically been addressed with varying techniques involving either repair or reconstruction. More recently, the potential biomechanical benefits of suture augmentation (SA), also known as internal brace, have attracted substantial attention and helped renew interest in ligament repair surgery. We evaluated the biomechanical and clinical outcomes of SA-based techniques in the following sports medicine procedures: medial ulnar collateral ligament repair of the elbow, thumb collateral ligament repair, anterior cruciate ligament repair, Achilles' tendon repair, and deltoid ligament repair. Published data on the use of SA to augment repairs of the ulnar collateral ligament, thumb collateral ligament, anterior cruciate ligament, Achilles' tendon, and deltoid ligament repair demonstrate improved time-zero biomechanical and promising short- to mid-term clinical outcomes. However, surgeons must be wary of potential complications, including joint overconstraint, nerve paresthesia, and infection. LEVEL OF EVIDENCE: Level V, expert opinion.
