Description of the Simple Ankle Value: A Simplified Patient-Reported Outcome Measure for the Assessment of Ankle and Hindfoot Function.

Background: The Simple Ankle Value (SAV) is a patient-reported outcome measure (PROM) in which patients grade their ankle function as a percentage of that of their contralateral uninjured ankle.

Purpose/hypothesis: The primary aims of this study were to validate the SAV and evaluate its correlation with other PROMs. It was hypothesized that the SAV would be seen as a valid score that provides results comparable with those of the Foot and Ankle Ability Measure (FAAM) and the European Foot & Ankle Society (EFAS) score.

Lateral unicompartmental knee arthroplasty is a safe procedure for post-traumatic osteoarthritis after lateral tibial plateau fracture: a case-control study at 10-year follow-up.

Purpose: Very few studies focus on lateral unicompartmental arthroplasty (LUKA) in the setting of post-traumatic osteoarthritis (PTOA). The hypothesis of our study is that LUKA is an effective procedure for isolated lateral PTOA with similar outcomes to non-traumatic LUKA.

Methods: Between 1990 and 2016, eighteen LUKA performed for isolated lateral tibiofemoral osteoarthritis secondary to tibial plateau fracture were retrospectively reviewed (post-traumatic group) and matched with a control group of thirty-six LUKA performed for non-traumatic OA.
