Allogenic Umbilical Cord Tissue as a Scaffold for Ankle Osteoarthritis

Osteoarthritis (OA) of ankle followed by injury to the talus is one of the most common disorders of ankle. Traditional treatment modalities have limitations and do not address the etiopathogenetic cause of OA. Perinatal tissue-derived biologics such as umbilical cords have shown potential for musculoskeletal regenerative medicine applications. This article qualitatively presents the in vitro, pre-clinical, clinical, and ongoing scientific literature exploring the application of umbilical cord tissue in the context of ankle OA. We identified only one clinical study wherein allogenic umbilical cord tissue was applied as a scaffold to the degenerated cartilage in the subtalar synovial joint. Administration of umbilical cord tissue is safe and potentially efficacious in patients with ankle OA. However, more in vitro, pre-clinical studies and high-powered, multi-center, non-randomized and randomized controlled trials are warranted to further establish the safety and efficacy of umbilical cord to justify its clinical use in ankle OA patients.
