The application of biological materials of carpal articular cartilage in athletic injury

摘要

This paper investigated the effect of biological materials on rehabilitation carpal articular cartilage injury in athletic injury, which aimed at provides ideal biological materials for the injury repair and functional reconstruction of carpal articular cartilage injury. Arthroscopic micro fracture technique combined with hyaluronic acid gel can improve the thickness of cartilage regeneration, which is more close to the hyaline cartilage; Calcium polyphosphate fiber/gelatin composite scaffold can meet the needs of tissue engineering scaffold composite porosity; Auto-genous periosteal graft fixation of bone marrow mesenchymal stem cells can promote the repair, generation and self-adaptation of articular cartilage. the carpal articular cartilage injury is common in exercise and training due to wrist joint physiological structure and biomechanical characteristic, tissue engineering of cartilage repair implant the cells and scaffold composite into the damaged tissues or organs, so as to achieve the purpose of wound repair and functional reconstruction, which provides a effective way for wrist joint cartilage injury.
