Results presented at the Virtual EFORT Congress showed patients who underwent either primary or revision ankle replacement had improved functional outcomes at 2-year follow-up.
Toby Jennison, FRCS (Orth) MBChB, MSC(Oxen), BSc, PGCert(MedEd), and colleagues collected preoperative and 2-year postoperative Manchester-Oxford Foot Questionnaire scores among 33 patients and 23 patients who underwent primary and revision ankle replacements, respectively.
“Statistical analysis was undertaken to look at the differences pre- and postop in both groups and between the two groups,” Jennison said in his presentation.
Jennison noted all of the primary replacements were performed with the Infinity total ankle system (Wright Medical), while 16 procedures in the revision group were performed with the Inbone II total ankle replacement system (Wright Medical) and seven were performed with a combination of the Inbone II and Invision total ankle revision systems (Wright Medical). Indications for revision surgery included nine aseptic loosenings, six infections, five cysts and three malpositions. Overall, 17 revision surgeries were performed as a single-stage procedure and six revisions were performed as a two-stage procedure, according to Jennison.
Results showed all Manchester-Oxford Foot Questionnaire Scores for overall walking, standing, pain and social interaction had a significant increase from preoperative to postoperative measures in both the primary and revision arthroplasty groups.
“All of these scores, though, increased significantly more for those undergoing primary arthroplasty than revision arthroplasty,” Jennison said.
