AOSSM 2022 Annual Meeting Recordings - no CME-Meniscus Replacement Options

Video Transcription

Video Summary

In this video, the speaker discusses meniscal replacement options for patients who experience pain after a partial meniscectomy. Three categories of meniscal replacement are discussed: segmental replacements or scaffolds, biological replacements and allograft transplantation, and synthetic replacements. The speaker explains the design considerations for segmental replacements and scaffolds, such as biocompatibility, biodegradability, biomechanical properties, porosity, and bioactivity. The advantages of meniscal scaffolds are preservation of meniscal tissue, restoration of biomechanical condition, and prevention or slowing of articular cartilage degeneration. However, there are also limitations, such as limited indications, challenging implantation procedures, and uncertain long-term outcomes. The speaker mentions two options currently on the market, the collagen meniscal implant and the ActiFit, and discusses their characteristics and results. The second category, meniscus allograft transplantation, is also explored, including relative indications, surgical techniques, complications, and outcomes. The speaker emphasizes that meniscus allograft transplantation is not experimental and has shown high success rates and improvements in pain and function. The speaker also mentions a new surface meniscus allograft replacement that is being actively used in Europe and is expected to receive FDA approval in the United States to fill the treatment gap between scaffolds and joint replacement.
