Optimizing pectoralis major tendon repair: a modified knotless suture anchor technique using high-strength suture and tape

Abstract

BackgroundRupture of the pectoralis major tendon is infrequent but has shown an increased incidence in athletes, particularly weightlifters during bench presses. Various techniques for repair exist, yet no established gold standard has been defined. MethodsWe present a modified surgical technique utilizing knotless suture anchors for pectoralis major tendon repair. The technique involves bringing the tendon end superiorly and inferiorly to the decorticated bone surface, ensuring broader tendon-to-bone contact. Knotless anchors with a unique suture locking mechanism facilitate tension adjustment. Additionally, the repair's strength is reinforced by employing both surgical tape and high-strength suture. ResultsThe utilization of both surgical tape and high-strength suture in conjunction with knotless suture anchors provides a secure and stable construct. This approach minimizes the risk of failure, reduces the potential for neurovascular injury associated with bicortical drilling, preserves imaging quality due to the absence of metal artifacts, and helps avoid the risk of fracture associated with traditional methods. However, surgeons should be aware of a potential disadvantage of increased surgical costs compared to traditional techniques. ConclusionsOur modified technique offers multiple advantages, including increased tendon-to-bone contact, enhanced stability, reduced neurovascular risks, and avoidance of potential fractures. This makes it a valuable option for successful pectoralis major tendon repairs. Surgeons should consider its benefits and weigh them against the associated costs for optimal patient care.
