Observations: 

The effects of shoes reducing varus instability of the knee on gait parameters, knee pain, and health-related quality of life (HRQOL) in patients with medial knee osteoarthritis were investigated.

Methods: 

Twelve patients with medial knee osteoarthritis wore shoes reducing varus instability of the knee.

Results and Conclusions: 

Gait velocity, stride length, step length, knee pain, and Japanese Knee Osteoarthritis Measure scores significantly improved in the postintervention period compared with the pre- and postcontrol periods. Therefore, shoes reducing varus instability of the knee can effectively improve gait parameters, knee pain, and HRQOL in patients with medial knee osteoarthritis.

降低膝盖内翻稳定性的鞋子对内侧膝骨关节炎女性的步态参数，膝盖疼痛和健康相关生活质量的影响

观察结果： 

鞋子减少对膝盖的内翻不稳的影响步态参数，膝关节疼痛和生活健康质量（HRQOL）患者的内侧膝关节骨性关节炎的影响。

方法： 

十二名膝内侧骨关节炎患者穿鞋，可减轻膝内翻稳定性。

结果与结论： 

与干预前后相比，干预后的步态速度，步幅，步长，膝盖疼痛和日本膝骨关节炎测量得分明显提高。因此，减少膝盖内翻不稳定的鞋子可以有效改善中膝骨性关节炎患者的步态参数，膝盖疼痛和HRQOL 。
