Knee scooter related injuries and satisfaction in patients following foot and ankle surgery

Abstract

BackgroundKnee scooters have become popular amongst foot and ankle surgeons for patients who are required to be non-weight bearing. Information is limited regarding falls and injuries sustained while using a knee scooter and potential contraindications to their use are ill-defined. No study has assessed patient reported injuries and satisfaction. This study aims to evaluates the patient’s perspective with regards to the use of a knee scooter. As a secondary aim we assessed for risk factors associated with knee scooter related injuries to try make recommendations for the safe use of a knee scooter. MethodsPatients who used a knee scooter during 2018–2020 were emailed a questionnaire assessing (1) demographic data, (2) medical history, (3) falls and injuries sustained, including the management of these injuries, and (4) patient satisfaction. This study is a descriptive, cross-sectional survey analysis. Results101/196 (51,5%) responses were received, which included 32 males and 69 females. The cohort had a mean age of 56.4 years, and BMI of 28.5. Mean time spent using the scooter was 6.7 weeks. Twenty-five respondents had fallen off the scooter, with 5 reporting injuries. One patient required medical attention for a shoulder injury. Cause of falls included hitting an obstacle, making a sharp turn, moving too fast, and moving downhill. There was no correlation between falls and patient comorbidities. Ninety-six percent of respondents reported a high satisfaction and preferred the scooter to crutches. ConclusionThe knee scooter is a safe, and well-tolerated, mobility aid for patients requiring non-weight bearing during their recovery, with a high satisfaction rate. Educating patients on correct use and common causes for falling is important as a preventative measure. Level of evidenceIV, retrospective case series.
