Arthroscopic Tibiotalar Arthrodesis Using an Arthroscopic Autologous Tissue Collector: A Technique Guide.

Tibiotalar arthrodesis is a common procedure performed in patients with ankle arthritis to relieve pain, restore function, and improve the quality of life. Obtaining proper bone-to-bone apposition is crucial to obtaining a solid fusion. Therefore, adequate joint preparation is critical. Open-joint preparation is the standard of care, but arthroscopic arthrodesis is becoming increasingly popular, as it can decrease tissue trauma, postoperative pain, hospital stay, and complications. The addition of bone matrix allograft and autograft also improves healing rates. Use of an arthroscopic autologous tissue collector through standard arthroscopic portals allows harvesting of bone matrix autograft without having to perform additional invasive bone harvesting outside of the affected joint. We present our technique for tibiotalar arthrodesis using an arthroscopic approach with an arthroscopic autologous tissue collector.
