“…1,34 Depending on the molecular weight and degree of crystallinity, mechanical properties of different bioabsorbable implants will behave differently in a physiologic environment. 44 This molecular weight and crystallinity can be altered to optimize the initial strength and length of time of resorption of an implant. Other variables being equal, the higher degree of crystallinity within a bioabsorbable material, the more slowly it will degrade and the longer it will maintain its strength.…”

Complications of Bioabsorbable Suture Anchors in the Shoulder

The development of the suture anchor has played a pivotal role in the transition from open to arthroscopic techniques of the shoulder. Various suture anchors have been manufactured that help facilitate the ability to create a soft tissue to bone repair. Because of reported complications of loosening, migration, and chondral injury with metallic anchors, bioabsorbable anchors have become increasingly used among orthopaedic surgeons. In this review, the authors sought to evaluate complications associated with bioabsorbable anchors in or about the shoulder and understand these in the context of the total number of bioabsorbable anchors placed. In 2008, 10 bioabsorbable anchor-related complications were reported to the US Food and Drug Administration. The reported literature complications of bioabsorbable anchors implanted about the shoulder include glenoid osteolysis, synovitis, and chondrolysis. These potential complications should be kept in mind when forming a differential diagnosis in a patient in whom a bioabsorbable anchor has been previously used. These literature reports, which amount to but a fraction of the total bioabsorbable anchors implanted in the shoulder on a yearly basis, underscore the relative safety and successful clinical results with use of bioabsorbable suture anchors. Product development continues with newer composites such as PEEK (polyetheretherketone) and calcium ceramics (tricalcium phosphate) in an effort to hypothetically create a mechanically stable construct with and improve biocompatibility of the implant. Bioabsorbable anchors remain a safe, reproducible, and consistent implant to secure soft tissue to bone in and about the shoulder. Meticulous insertion technique must be followed in using bioabsorbable anchors and may obviate many of the reported complications found in the literature. The purpose of this review is to provide an overview of the existing literature as it relates to the rare complications seen with use of bioabsorbable suture anchors in the shoulder.

Bioresorbable implants are being widely used for fracture fixation in orthopaedic surgery and the market is expanding rapidly worldwide. Bioresorbable materials slowly dissolve in the human body, such that a second operation to remove the synthetic material is not needed. Bioresorbable implants have expanded the armamentarium of the surgeon, especially in the field of sports medicine. Interference screws, plates, pins, suture anchors, meniscal repair implants, and simple fracture fixation implants are the most commonly used resorbable implants for anterior cruciate ligament reconstruction, shoulder surgery, meniscal repair, and fracture care. However, many clinicians continue to rely on metal fixation, mainly due to the high mechanical strength and to the complications reported with some of the available resorbable implant materials. The goal of the present paper is to present an overview on the available resorbable materials and their applications with a particular focus on new developments and trends in the field.
