| Popis: | Category: Ankle Arthritis Introduction/Purpose: Fourth generation ankle replacements benefit from improved surgical technique, respect for bony preservation, and increased surgeon awareness of operative indications. In some studies, pre-operative degree of deformity has been reported to influence survivorship, pain, and functional outcomes. The purpose of this multi-institutional study was to evaluate whether pre- operative deformity affects prospectively collected patient reported outcome measures (PROMs) of a fourth-generation total ankle replacement. Methods: Patients presenting for a total ankle replacement at 9 institutions were prospectively enrolled and implanted in a variety of academic and private settings. Each patient received an INFINITY ankle prosthesis. (Styker, Memphis, TN, USA). The degree of deformity was radiographically classified pre-operatively as severe if ankle varus or valgus was greater than 10° in the coronal plane. PROMs were recorded pre-operatively and at 6 months, 12 months, and 24-month intervals. The following PROMs were collected: Ankle Osteoarthritis Score (AOS), PROMIS Global Physical Health, and Foot and Ankle Outcome Score (FAOS). The preoperative and latest follow-up scores for patients with two years of follow-up were analyzed. Results: A total of 147 patients were enrolled in the study. Fifty-two patients exhibited a pre-operative ankle deformity of greater than 10° varus or valgus. Eighty-eight patients had 24 months of follow-up. All patients with severe deformity had significant improvements in all domains of the AOS, PROMIS, and FAOS Scores (p |
