Fractures of the posterior malleolus: a systematic review and analysis of patient-reported outcome scale selection.

Purpose: Despite the extensive use of PROs in ankle fracture research, no study has quantified which PROs are most commonly used for assessing outcomes of patients who sustain fractures of the posterior malleolus. The purpose of this study was therefore to quantify which PROs are most commonly used for outcome research after posterior malleolus fractures.

Methods: A systematic search was performed using the preferred reporting items for systematic reviews and meta-analyses guidelines.
