Ankles with varus, valgus or neutral alignment had similar outcomes after ankle arthroplasty

Results published in The Journal of Bone and Joint Surgery showed patients with either varus or valgus malalignment of the coronal plane tibiotalar angle who underwent mobile-bearing total ankle arthroplasty had similar outcomes compared to patients with neutral alignment.

Researchers categorized 140 patients who underwent primary total ankle arthroplasty with a mobile-bearing Hintegra prosthesis (Newdeal) into varus, valgus or neutral groups according to the preoperative coronal plane tibiotalar angle. Preoperatively and at final follow-up, researchers assessed the ankle osteoarthritis scale pain and disability score, American Orthopaedic Foot & Ankle Society ankle-hindfoot score, VAS pain score, SF-36 physical component summary score and range of motion. Researchers also collected radiographs preoperatively and at 1-month, 3-months, 6-months and 12-months postoperatively and annually thereafter.

At final follow-up, results showed no differences between the varus, valgus and neutral groups in regard to mean ankle osteoarthritis scale pain and disability score, American Orthopaedic Foot & Ankle Society ankle-hindfoot score, SF-36 physical component summary score, VAS pain score and ankle range of motion. Compared with the neutral group, researchers found the varus group had a significantly less corrected degree of coronal alignment, as well as significantly more concomitant procedures.

The three groups showed no differences in the prevalence of major complications, according to results. At a mean follow-up of 7.3 years, researchers found an overall probability of implant survivorship of 91.1%. – by Casey Tingle
