Suture Anchor Construct for an Exogenous Ligament Repair for Subtalar Joint Instability-A Novel Technique

Abstract

Subtalar joint ligament sprains are often missed in the setting of chronic inversion ankle injuries. This can lead to pain and instability of the subtalar joint. In many cases, without proper identification, the patient may eventually undergo an unnecessary subtalar joint fusion rather than a ligament reconstruction. Achilles, peroneus brevis, and gracilis tendon grafts have been described to repair subtalar ligament instability in the literature. To our knowledge, the use of exogenous ligament repair technique using nonabsorbable suture made of Ultra High Molecular Weight Polyethylene (UHMWPE) and suture anchors has not been described for subtalar joint stabilization. Here we present a case of 17-year-old female who underwent subtalar joint stabilization with a suture anchor construct for bilateral chronic subtalar joint instability.
