Which suture material is not suitable for attaching tendon to bone?

The most suitable choice for this question indicates that Poliglecaprone 25, commonly known as Monocryl, is not ideal for attaching tendon to bone. Monocryl is a synthetic absorbable suture made of poliglecaprone, which is primarily used for soft tissue approximation and ligation. While it has good tensile strength initially, it loses its strength relatively quickly due to its absorbable nature.

In tendon-to-bone repairs, the goal is to achieve a strong, lasting fixation that will withstand the forces of muscle contraction and allow for proper healing. Materials that are more durable and provide longer-term support, such as non-absorbable sutures (e.g., Prolene), are more appropriate for this purpose.

Other materials like Vicryl and Silk may also be used, depending on the specific surgical context and practitioner preference, but they can maintain their integrity longer or provide necessary properties for successful healing in different scenarios. Therefore, Monocryl is least suitable among the options when it comes to the specific task of attaching tendon to bone.
