: Knee osteoarthritis affects 9.3 million adults over age 45 years in the United States. There is significant disability associated with this condition. Given the potential complications and the significant cost to the health care system with the dramatic increase in total knee arthroplasties performed for this condition, assessment of the efficacy of nonoperative modalities, such as offloading knee braces, is essential as part of optimizing nonoperative treatment for this condition.
: To determine the effectiveness of valgus offloader braces in improving clinical outcomes for patients with medial compartment knee osteoarthritis.
: Three databases (PubMed, MEDLINE, and EMBASE) were searched from database inception through July 28, 2017.
: Studies reporting outcomes of valgus offloader knee braces in the treatment of medial compartment knee osteoarthritis were included.
: Systematic review.
: Level 4.
: Data pertaining to demographics, descriptive statistics, and clinical outcomes were extracted from the included studies. The methodological quality of included studies was evaluated.
: A total of 31 studies were included, with a total of 619 patients. The majority of studies reported improved pain outcomes using valgus offloader braces. However, variable results were reported as to whether valgus offloader braces significantly improved functional outcomes and stiffness. Offloader bracing was more effective at reducing pain when compared with neutral braces or neoprene sleeves.
: Valgus offloader bracing is an effective treatment for improving pain secondary to medial compartment knee osteoarthritis. The literature remains unclear on the effectiveness of valgus offloader braces with regard to functional outcomes and stiffness. Larger prospective randomized trials with consistent outcome assessment tools and consideration of patient compliance would be beneficial to more accurately determine treatment effects of valgus offloader bracing.
在美国，有 930 万 45 岁以上的成年人患有膝骨关节炎。这种疾病会导致明显的残疾。鉴于这种疾病进行的全膝关节置换术数量急剧增加，可能会出现并发症，并且给医疗保健系统带来巨大的成本，因此评估非手术治疗方法（如减轻膝关节负重的支具）的疗效至关重要，这是优化这种疾病的非手术治疗的一部分。
确定外翻式减负支具在改善内侧间室膝骨关节炎患者临床结果方面的有效性。
从数据库创建开始到 2017 年 7 月 28 日，共检索了三个数据库（PubMed、MEDLINE 和 EMBASE）。
纳入报告外翻式减负支具治疗内侧间室膝骨关节炎的结果的研究。
系统评价。
4 级。
从纳入的研究中提取与人口统计学、描述性统计和临床结果相关的数据。评估了纳入研究的方法学质量。
共纳入 31 项研究，共 619 例患者。大多数研究报告使用外翻式减负支具可改善疼痛结局。然而，关于外翻式减负支具是否显著改善功能结局和僵硬，报告的结果存在差异。与中性支具或氯丁橡胶袖套相比，减负支具更能有效减轻疼痛。
外翻式减负支具是治疗内侧间室膝骨关节炎引起的疼痛的有效方法。关于外翻式减负支具在功能结局和僵硬方面的有效性，文献仍不清楚。更大规模的前瞻性随机试验，使用一致的结果评估工具并考虑患者依从性，将有助于更准确地确定外翻式减负支具的治疗效果。
