SEATTLE — Radiographic sagittal plane range of motion after total ankle replacement was positively associated with patient-reported outcomes, according to a presenter at the American Orthopaedic Foot and Ankle Society Annual Meeting.

“So basically, greater range of motion (ROM) equals better postoperative patient-reported outcome measures (PROMs),” Kamran Hamid, MD, MPH, said during his presentation.

He added, “When we looked at preoperative to postoperative changes in all of these outcome measures, they were significant as far as what is published for [minimal clinically important differences] MCIDs.”

Hamid and colleagues conducted a 2-year minimum follow-up of 88 patients who underwent total ankle replacement. Inclusion criteria included preoperative and postoperative measures for the foot and ankle disability index (FADI), short musculoskeletal function assessment (SMFA) bother and function indices, VAS and SF-36. Investigators collected standardized weight-bearing maximum dorsiflexion radiographs and plantarflexion sagittal radiographs.

Findings showed from the preoperative evaluation to the most recent follow-up visits, all PROMs improved. There was a significant correlation between final ankle ROM and postoperative FADI, SF-36 mental component score, SMFA bother and function indices and VAS score.

Hamid and colleagues also found FADI, SF-36 mental component score and SMFA function were positively correlated with dorsiflexion; however, these outcomes were not impacted by plantarflexion. There were no differences seen for prosthesis type, fixed-bearing design, mobile-bearing design and etiology. – by Monica Jaramillo
