Total ankle arthroplasty can improve outcomes in coronal plane deformity

By Casey Tingle

Although research has shown satisfactory outcomes for total ankle arthroplasty in patients with preoperative coronal plane deformity of greater than 10°, it is still considered a relative contraindication; however, researchers recently reported the effective use of total ankle arthroplasty in a patient with a severe preoperative varus deformity without the need for osteotomy.

The researchers performed total ankle arthroplasty using the Inbone II Prophecy total ankle system (Wright Medical Technologies) in a 54-year-old man who presented with severe right-ankle varus deformity of 29°. The patient also underwent subsequent Brostrom Evans ligament reconstruction for lateral ankle instability. The researchers used preoperative CT imaging navigation to develop a patient-specific guide that was used intraoperatively.
