Introduction: Tendon and ligament injuries are a frequent and debilitating issue that affects many patients worldwide. The predominant solution is the suture thread, which is not without potential side effects and limitations. Implantable medical devices have gained more attention as an alternative approach. However, due to the many challenges of the inner body environment (limited available space, chemically aggressive environment, etc), the development of suitable devices is not exempt from practical and technical difficulties.
Areas covered: Here, implantable medical devices for tendon and ligaments injuries are reviewed and discussed. Commercially-available products and registered patents are all considered as long as they fit the standard definitions of 'implantable medical devices' (reported in the Introduction). The research was then narrowed down to five commercial products, deemed as the most representative of the whole market. Their effectiveness and performance are analysed, as well as the possible areas of improvement and development.
Expert opinion: Commercially available products present overall superior mechanical performances than suture techniques. Nevertheless, these latter ones might be still preferred for their wider range of customization. This aspect, and many others, could represent an area of improvement for implantable medical devices, to further explore their potential for tendon and ligament repair.
