“…Therefore, using both interventions of knee brace and LWLs together could be more effective on pain compared with using them separately. 14 Therefore, based on the findings of VAS, one of possible explanations may be that concurrent use of knee valgus brace and insoles can apply corrective force by changing mechanical alignment and valgus moment. Nevertheless, the pain measured by WOMAC was improved in both groups with no significant difference between the groups.…”

“…12,13 The results of a recent systematic review showed using both LWI and brace together can be more effective in the management of knee OA. 14 Considering the positive effect of both physical therapy and orthosis interventions in individuals with OA, information on which one is more effective in reducing pain and improving function is insufficient. This study aimed to compare the two common conservative treatments (orthosis and physical therapy) on pain and function in patients with knee OA.…”

“…On the other hand, orthosis management including knee valgus braces and lateral wedge insoles (LWIs) could result in decreased pain and improved physical function by changing the mechanical alignment of the leg, transferring loading during weight-bearing from the medial to the lateral knee compartment through the application of a valgus moment around the knee joint 12,13 . The results of a recent systematic review showed using both LWI and brace together can be more effective in the management of knee OA 14 …”

INTRODUCTION Orthosis and physical therapy are two conservative managements for knee osteoarthritis (OA), but the question is which is better for alleviating pain and improving function? The aim of this study was to compare two interventions of orthosis and physical therapy on pain and function in patients with knee OA. METHODS In this quasi-experimental study, 31 individuals with medial knee OA were recruited into two groups including orthosis group (combination of insole and brace [n = 14]) and physical therapy group (n = 17). Pain severity was measured by visual analog scale (VAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire. Also, daily activity was measured by the WOMAC questionnaire at baseline and after 6-week follow-up. Wilcoxon signed rank and Mann-Whitney U tests were used to determine significant difference for intragroup and intergroup comparisons, respectively. RESULTS The orthosis group (using both knee brace and LWLs) had a better result for pain score related to VAS than the physical therapy group immediately after and 6 weeks of using the intervention, with a significant difference between the two groups (P = 0.006). Regarding the WOMAC items including pain and daily activity, both groups had significant differences after the 6-week period of using the intervention, with no significant difference between the groups. CONCLUSIONS Based on the findings, pain and daily activity related to the WOMAC questionnaire were improved in both orthosis and physical therapy groups, with no differences between the two interventions. The orthosis group had better results in pain related to VAS. CLINICAL RELEVANCE The aim of this study was to find whether physical therapy or orthosis best improves pain and function of knee OA patients.

“…Lateral wedge insoles are orthotic devices that are placed within the shoes in order to significantly reduce the risk factors associated with knee OA [5]. The biomechanical result of the use of lateral wedge insoles seems to be a decrease in the external knee adduction moment (EKAM) [6,7]. EKAM is a parameter that quantifies the contribution of the ground reaction force (GRF) to the rotation of the lower leg around the knee.…”

Can Slight Variations to Lateral Wedge Insoles Induce Significant Biomechanical Changes in Patients with Knee Osteoarthritis?

Lateral wedge insoles are recommended in order to minimize the impacts of osteoarthritis of the knee. The amount of wedging required to induce a biomechanical response with clinical significance is still controversial. This study aimed to investigate the immediate biomechanical effects of different amounts of wedging in symptomatic medial knee OA. A 3D motion capture system and five force platforms were used to acquire walking kinematic and kinetic data along a 10 m walkway. Each participant was tested for six different lateral wedge insoles (0, 2, 4, 6, 8, and 10°) in a randomized order. Thirty-eight patients with medial osteoarthritis of the knee were recruited. The application of insoles resulted in an incremental reduction of the first peak of the external knee adduction moment under all experimental conditions in comparison with the control condition (0° insole). A significant increase (p < 0.05) was observed in peak ankle eversion and in ankle eversion at the first peak of the external knee adduction moment with insoles higher than 8° and 6°, respectively. Slight variations to lateral wedge insoles, greater than 2°, appear to induce significant biomechanical changes in patients with knee osteoarthritis.

“…An LWI can laterally displace the center of mass and decrease knee adduction. This change produces a decrease in pressure on the medial compartment of the knee and, therefore, improves function [ 21 ].…”

The lateral wedge insole (LWI) is a typical orthopedic treatment for medial knee osteoarthritis pain, chronic ankle instability, and peroneal tendon disorders. It is still unknown what the effects are in the most important joints of the foot when using LWIs as a treatment for knee and ankle pathologies. Objectives: The aim of this study was to determine the influence of LWIs on the position of the midfoot and rearfoot joints by measuring the changes using a tracking device. Methods: The study was carried out with a total of 69 subjects. Movement measurements for the midfoot were made on the navicular bone, and for the rearfoot on the calcaneus bone. The Polhemus system was used, with two motion sensors fixed to each bone. Subjects were compared by having them use LWIs versus being barefoot. Results: There were statistically significant differences in the varus movement when wearing a 4 mm LWI (1.23 ± 2.08°, p < 0.001) versus the barefoot condition (0.35 ± 0.95°), and in the plantarflexion movement when wearing a 4 mm LWI (3.02 ± 4.58°, p < 0.001) versus the barefoot condition (0.68 ± 1.34°), in the midfoot. There were also statistically significant differences in the valgus movement when wearing a 7 mm LWI (1.74 ± 2.61°, p < 0.001) versus the barefoot condition (0.40 ± 0.90°), and in the plantar flexion movement when wearing a 4 mm LWI (2.88 ± 4.31°, p < 0.001) versus the barefoot condition (0.35 ± 0.90°), in the rearfoot. Conclusions: In the navicular bone, a varus, an abduction, and plantar flexion movements were generated. In the calcaneus, a valgus, an adduction, and plantar flexion movements were generated with the use of LWIs.
