To determine patient satisfaction and safety with wheeled knee walkers, we performed a retrospective, observational, and descriptive study. Inclusion criteria were age ≥18 years, unilateral foot or ankle surgery, non-weightbearing status, and being given the option of using the knee walker. Surveys were sent to eligible patients, and chart review included only those patients who returned surveys. Primary endpoints were occurrence and frequency of falls. Secondary endpoints were patient demographics, comorbidities, knee walker characteristics, duration of use, and patient satisfaction. We also attempted to identify associations between falls and patient characteristics. Eighty participants, 51 females and 29 males, responded adequately to the survey. The mean age of respondents was 55.6 ± 13.0 years and their mean body mass index (BMI) was 30.2 ± 5.9 kg/m. Most used a steerable, 4-wheeled knee walker. Almost half (46%) had no prior experience with any type of walking aids, and none had experience using a knee walker. Two thirds (66%) did not receive any instruction on usage of the knee walker. Thirty-four (43%) of the 80 respondents fell while using the knee walker; nearly two thirds (62%) of those who fell reported multiple falls. Sixteen (55%) of 29 males compared to 18 (36%) of 50 females reported falling (p = .097). There was no statistical association between falls and age, BMI, or number of comorbidities. Most respondents (91%) who fell still reported satisfaction with the knee walker. Nearly half (43%) experienced falling, and nearly two thirds (64%) of those who fell had multiple falls.
为了确定使用轮式膝关节助行器的患者满意度和安全性，我们进行了一项回顾性、观察性和描述性研究。纳入标准为年龄≥18 岁、单侧足部或踝关节手术、非负重状态和可选择使用膝关节助行器。向符合条件的患者发送调查问卷，仅对返回调查问卷的患者进行病历回顾。主要终点是跌倒的发生和频率。次要终点是患者人口统计学特征、合并症、膝关节助行器特征、使用时间和患者满意度。我们还试图确定跌倒与患者特征之间的关联。80 名参与者（51 名女性和 29 名男性）对调查做出了充分回应。应答者的平均年龄为 55.6±13.0 岁，平均体重指数（BMI）为 30.2±5.9kg/m。大多数人使用可转向的四轮膝关节助行器。近一半（46%）以前没有使用过任何类型的助行器，也没有人有使用膝关节助行器的经验。三分之二（66%）没有接受过膝关节助行器使用方面的任何指导。80 名应答者中有 34 名（43%）在使用膝关节助行器时跌倒；其中近三分之二（62%）跌倒者报告多次跌倒。29 名男性中有 16 名（55%）报告跌倒，而 50 名女性中有 18 名（36%）报告跌倒（p=0.097）。跌倒与年龄、BMI 或合并症数量之间没有统计学关联。大多数跌倒的应答者（91%）仍然对膝关节助行器感到满意。近一半（43%）经历过跌倒，其中近三分之二（64%）跌倒者有多次跌倒。
