Ligament augmentation techniques (LAT) use a synthetic ligament that spans the anatomic length of the injured ligament, anchoring to bone on both ends.

However, these conclusions were based on limited case series with older prosthetic designs, and the potential for successful conversion in this challenging patient population remains unclear. This retrospective study examines the midterm follow-up of 21 patients treated for a conversion of failed ankle arthrodesis by a single surgeon using a standard technique with a single prosthesis, with a focus on the treatment of 5 patients with a deficient distal fibula.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Between May 2010 and August 2019, 27 patients underwent conversion using a prosthesis with an intramedullary tibial component, 21 of which were available for the study. Six patients had a deficient distal fibula, and 5 were available for follow-up. Our primary outcome measure was having a total ankle arthroplasty in place. Secondary outcomes were evaluated postoperatively with a visual analog scale, the American Orthopaedic Foot & Ankle Society (AOFAS) ankle and hindfoot score, a satisfaction survey, and radiographic assessment of the arthroplasty and any concomitant hindfoot fusions.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Mean follow-up for all patients was 7.6 (2.6-11.8) years, with follow-up of the deficient fibula group of 8.2 (4.9-11.8) years. Complications included malleolar fracture with or without subsequent surgery (n = 5), varus deformity (n = 1), and wound dehiscence or infection (n = 2). At final follow-up, all patients, including the 5 with a deficient distal fibula, had an intact ankle arthroplasty, although 3 with intact fibulas had undergone prosthetic revision. Postoperative dorsiflexion was 4.5 ± 5.1 degrees and plantarflexion 20.9 ± 13.37 degrees. There were no pseudarthroses in the 11 patients with concomitant hindfoot arthrodesis. Mean (±SD) VAS score was 4.4 ± 3.0 and AOFAS score was 71.2 ± 21.7. Sixty-seven percent reported that they were satisfied or very satisfied, with 16% dissatisfied or very dissatisfied.
