Laterally elevated wedged insoles in the treatment of medial knee osteoarthritis: a prospective randomized controlled study.
OBJECTIVE To compare the clinical effects of laterally wedged insoles and neutrally wedged insoles ( used as control ) in patients with medial femoro-tibial knee osteoarthritis ( OA ) . DESIGN 6-month prospect i ve r and omized controlled study . PATIENTS out patients with painful medial femoro-tibial knee OA . OUTCOME MEASURES patient 's overall assessment of disease activity ( 5 grade scale ) , WOMAC index subscales and concomitant treatments . STATISTICAL ANALYSIS Performed as an intention-to-treat analysis . Main criterion : improvement in the patient 's assessment of activity ( defined as a reduction of 1 grade or more at month 6 compared to baseline , and no intraarticular injection or lavage during the study ) . Secondary criteria for assessment : ( a ) improvement in the patient 's assessment of activity at months 1 and 3 compared to baseline , ( b ) improvement in the WOMAC subscales at months 1 , 3 and 6 , compared to baseline ( defined as an improvement of at least 30 % , and no intraarticular injection or lavage during the study ) and ( c ) concomitant therapies ( analgesics and NSAIDs ) . RESULTS The baseline characteristics of the 156 recruited patients ( 41 males , 115 females , mean age 64.8 years ) were not different in the two treatment groups . At months 1 , 3 and 6 the percentages of patients with improvement in assessment of disease activity , in WOMAC pain , joint stiffness , and physical functioning subscales were similar in the two groups . The number of days with NSAIDs intake during the previous 3 months was decreased at month 6 compared with baseline in the group furnished with laterally wedged insoles ( 14.1 days+/-28 vs 9.9 days+/-27 , P=0.04 , Wilcoxon paired test ) , while it remained unchanged in the other group ( 15.5 days+/-24 vs 15+/-28 , P=0.56 ) . Compliance and tolerance were satisfactory . Compliance was different between the two groups at month 6 , with a greater frequency of patients who wore insoles permanently in the laterally wedged insole group than in the other group ( 87.8 % vs 74.3%;P=0.032 ) . CONCLUSION This study failed to demonstrate a relevant short-term symptomatic effect of laterally-wedged insoles in medial femoro-tibial OA . However , the decrease in NSAIDs consumption together with better compliance in the treated group are in favor of a beneficial effect of laterally-wedged insoles in medial femoro-tibial OA
