Kevin Stone: The bio-future of joint replacement

The speaker shares his personal journey of knee injuries and how it led him to pursue orthopedic surgery. He discusses the prevalence of arthritis and introduces biologic replacements as a natural alternative to artificial components. Through case studies, he illustrates successful biologic treatments using human and animal tissues. Challenges such as donor tissue scarcity are addressed with solutions like using animal tissue, which involves overcoming immunological barriers. The talk concludes with advancements in biologic knee replacements and the potential for global application.
