Tendon repair is a field of research focused on developing surgical techniques and treatments to repair damaged or injured tendons in the body. Tendons are the fibrous tissues that connect muscles to bones, and injuries to tendons can result in pain, weakness, and decreased range of motion. Research in tendon repair aims to improve the outcomes of surgical procedures, develop innovative therapies such as stem cell treatments or tissue engineering approaches, and enhance rehabilitation protocols to optimize healing and restore function in individuals with tendon injuries. This research area is essential for improving the quality of life for individuals with tendon injuries and reducing the potential for long-term disability.
