A six-month followup of a randomized trial comparing the efficacy of a lateral-wedge insole with subtalar strapping and an in-shoe lateral-wedge insole in patients with varus deformity osteoarthritis of the knee.
OBJECTIVE To assess the effect of a lateral-wedge insole with elastic strapping of the subtalar joint on the femorotibial angle in patients with varus deformity of the knee . METHODS The efficacy of a wedged insole with subtalar straps and that of a traditional wedged insole shoe insert were compared . Sixty-six female out patients with knee osteoarthritis ( OA ) were r and omized ( according to birth date ) to be treated with either the strapped or the traditional inserted insole .  St and ing radiographs with unilateral insole use were used to analyze the femorotibial angles for each patient . In both groups , the baseline and 6-month visual analog scale ( VAS ) scores for subjective knee pain and the Lequesne index scores for knee OA were compared . RESULTS The 61 patients who completed the 6-month study were evaluated . At baseline , there was no significant difference in the femorotibial angle ( P = 0.66 ) and the VAS score ( P = 0.75 ) between the 2 groups . At the 6-month assessment , the 29 subjects wearing the subtalar-strapped insole demonstrated a significantly decreased femorotibial angle ( P < 0.0001 ) and significantly improved VAS scores ( P = 0.001 ) and Lequesne index scores ( P = 0.033 ) compared with their baseline assessment s. These significant differences were not observed in the 32 subjects assigned to the traditional shoe-inserted wedged insole . CONCLUSION These results suggest that an insole with a subtalar strap maintained the valgus correction of the femorotibial angle in patients with varus knee OA for 6 months , indicating longer-term clinical improvement with the strapped insert compared with the traditional insert
