Absorbable Nail Fixation of Biologic Membrane for Treatment of Cartilage Defects by Matrix-Induced Autologous Chondrocyte Implantation

Injuries to articular cartilage caused by a variety of factors are common clinically and can impair quality of life and lead to long-term dysfunction in a manner similar to osteoarthritis, which has led to the development of various repair techniques for articular cartilage injury. Although each technique has its own limitations and advantages, matrix-induced autologous chondrocyte implantation has been widely used and achieved good clinical results. We present a technique for fi xing bio fi lms with absorbable nails with a " Roman column structure " as the main structure. The described technique allows stable immobilization of the bio fi lm while ensuring that subsequent cartilage damage repair can proceed smoothly.
