Healing of Complete Tear of the Anterior Talofibular Ligament and Early Ankle Stabilization after Autologous Platelet Rich Plasma: a Case Report and Literature Review.

Lateral Ankle sprain (LAS) is a common sports injury associated with recurrent ankle sprain, chronic ankle instability (CAI) and post-traumatic ankle osteoarthritis (PTOA). Platelet Rich Plasma (PRP) has been increasingly used for herapeutic applications in sports-related injuries, and is thought to stimulate tissue healing. We reported a case of LAS with complete tear of anterior talofibular ligament, which showed complete healing of ligament and early ankle stabilization after PRP. The healing is supported by dynamic ultrasound images and magnetic resonance imaging. We therefore proposed that PRP may serve as an alternative non-surgical treatment option in LAS in future research, with the potential to prevent the development of CAI and PTOA. Level of evidence: IV.
