外側楔型鞋墊對內側膝退化性關節炎患者之療效

Abstract

Background: Medial compartment osteoarthritis (OA) of the knee is one of the most prevalent and disabling chronic conditions affecting older adults. This study assesses the efficacy of an inserted lateral wedged insole for the conservative treatment of medial compartment knee OA.Methods: Thirteen outpatients (9 females and 4 males with a mean age of 71.0 and a standard deviation of 5.5) with medial compartment knee OA were prospectively treated with an inserted lateral wedged insole with an elevation of 12 mm for three months. The baseline and three-month visual analog scale (VAS) scores for subjective knee pain and the remission score of the Lequesne index of severity for knee OA were compared. Standing radiographs with and without insoles were also used to analyze the femorotibial, talocalcaneal, and talar tilt angles at the baseline and at the final assessment. Results: Participants wearing the inserted lateral wedged insole showed a significant improvement in their VAS pain scores and remission scores in the Lequesne index (P＜0.0001). However, these statistically significant differences were not found in all angles when compared with values at the baseline, immediate, and three-month assessments. Conclusions: The inserted lateral wedged insole induced a symptomatic relief in patients with medial compartment knee OA, but it did not significantly improve the radiographs taken in the static position. The therapeutic effect should be further evaluated during the static and dynamic phases using a motion analysis system, as well as force plates to determine the kinematic and kinetic effects of the treatment. Hence, a longer-term clinical follow up should also be considered in future studies.
