Implantable Biologics for Soft Tissue Surgery Reinforcement.

Soft tissue reinforcement focuses on medical grafts that are designed to support and regenerate soft tissue under or near suture lines. Soft tissue is defined as areas of similarly specialized cells that function to connect, support, and surround other structures and organs of the body. These tissues include skin, subcutaneous tissue, fascia, ligaments, tendons, fibrous tissues, fat, synovial membranes, and muscle. Most of the implantable devices used for this purpose are made of collagen, the most abundant protein in mammals and a key component of the extracellular matrix of soft tissues that allows for tissue repair. For suture line reinforcement, exogenous collagen from various sources is implanted under or in continuity with the suture line to allow for increased strength and better healing. First introduced in the field of breast reconstruction, this practice is now also used in hernia repair, dural repair, vaginal slings, amputation reinforcement, tendon repair reinforcement, and even dental soft tissue regeneration.
