Soft tissues in the body include tendons, ligaments, fascia, skin, fibrous tissue, skeletal muscle, and synovial membrane. Soft tissue injury is caused due to traumatic injury, fall, sudden twist, and repetitive motion of body. A person recovers from a soft tissue injury on the time of injury and the healing process. Once soft tissues (fascia, tendons or muscles) are injured, the pain and inflammation may eventually resolve and the healing process continues long after. Acute (protective phase), sub-acute (repair phase), late stage (remodeling phase), and chronic phase are the various phases of soft tissue injuries. Acute stage is the initial phase of the injury and is relatively a short phase, wherein the person experiences severe pain, bleeding, and swelling being experienced by the concerned patient. Sub acute stage is an essential component of the tissue repair process wherein repairing of the injured tissue takes place, and it lasts for approximately six weeks after the injury. During the repair phase, new blood vessels grow in the injured area, thus, maximizing the transport within the tissue. In the late stage, healing is continuum, and collagen maturation and remodeling is being initiated. In this process, collagen is realigned along the line of stress. Strains, sprain, contusion, bursitis, tendonitis, and stress injuries are some of the common soft tissue injuries. Soft tissue repair products are used to repair and reconstruct soft tissue injuries. Soft tissue repair matrix is a collagen matrix used for the repair and replacement of soft tissue. Hernia repair, breast reconstruction repair, skin repair, dural repair, vaginal sling procedures, dental and orthopedic are some of the applications of the soft tissue repair.
