Knee joint osteoarthritis (OA) is one of the most incapacitating diseases affecting older population, which is associated with pain and functional limitation. Various kinds of conservative treatment have been used to decrease knee pain and to improve the quality of life of the subjects suffering from this disease. There are discrepancies in the clinical effects reported for the use of lateral wedge insole in spite of being used as one of the first conservative mechanical treatments for patients with medial compartments of knee OA.
A total of 36 subjects with medial knee compartment OA were recruited in this research project. Subjects were randomized into two groups to receive 3- and 7-mm lateral wedge insoles based on the date of birth of the participants. Some parameters such as severity of knee pain, Tibiofemoral angle (TFA), severity of OA, and quality of life were selected in this research project.
The use of both 3-mm and 7-mm lateral wedge insole improves the quality of life and decreases knee joint pain. However, the effect of 7 mm lateral wedge insole was more than that of 3 mm.
Using lateral wedge insole is a simple, inexpensive therapy for decreasing pain and improving quality of life; however, most research must be carried out to find the effects of lateral wedge on severity of knee joint OA and aligning TFA.
膝关节骨关节炎（OA）是影响老年人群的最致残性疾病之一，与疼痛和功能受限相关。已采用各种保守治疗方法来减轻膝关节疼痛并改善患有这种疾病的受试者的生活质量。尽管外侧楔形鞋垫被用作膝关节内侧间室OA患者的首批保守机械治疗方法之一，但关于其临床效果的报道存在差异。
本研究项目共招募了36名膝关节内侧间室OA患者。根据参与者的出生日期，将受试者随机分为两组，分别使用3毫米和7毫米的外侧楔形鞋垫。本研究项目选取了一些参数，如膝关节疼痛严重程度、胫股角（TFA）、OA严重程度和生活质量。
使用3毫米和7毫米的外侧楔形鞋垫均可改善生活质量并减轻膝关节疼痛。然而，7毫米外侧楔形鞋垫的效果优于3毫米的。
使用外侧楔形鞋垫是一种简单、廉价的减轻疼痛和改善生活质量的治疗方法；然而，必须开展更多研究以探究外侧楔形鞋垫对膝关节OA严重程度和调整胫股角的影响。
