External Knee Adduction Moment

Progression of knee osteoarthritis (OA) has been shown to occur in the presence of an increased load at the medial compartment [1]. Current gait analysis techniques allow researchers to use inverse dynamic techniques to calculate external knee adduction moments. These moments correlate to varus knee stresses and increased load in the medial knee compartment. These abnormal stresses have been hypothesized to play a role in the destruction of articular cartilage [2]. Previous authors have suggested that walking velocity will affect the adduction moment and that decreasing walking speed may reduce the maximal knee external moment during gait [3]. Based on these previous findings, we investigated various walking speeds in subjects with mild, moderate and severe OA and the effect on the external knee adduction moment.

The present study compared the effect between walking exercise and a newly developed sensor-based gait retraining on the peaks of knee adduction moment (KAM), knee adduction angular impulse (KAAI), knee flexion moment (KFM) and symptoms and functions in patients with early medial knee osteoarthritis (OA). Eligible participants (n = 71) with early medial knee OA (Kellgren-Lawrence grade I or II) were randomized to either walking exercise or gait retraining group. Knee loading-related parameters including KAM, KAAI and KFM were measured before and after 6-week gait retraining. We also examined clinical outcomes including visual analog pain scale (VASP) and Knee Injury and Osteoarthritis Outcome Score (KOOS) at each time point. After gait retraining, KAM1 and VASP were significantly reduced (both Ps < 0.001) and KOOS significantly improved (p = 0.004) in the gait retraining group, while these parameters remained similar in the walking exercise group (Ps ≥ 0.448). However, KAM2, KAAI and KFM did not change in both groups across time (Ps ≥ 0.120). A six-week sensor-based gait retraining, compared with walking exercise, was an effective intervention to lower medial knee loading, relieve knee pain and improve symptoms for patients with early medial knee OA.

Background:Patients suffering from mild-to-moderate medial compartment knee osteoarthritis may be treated with an unloader knee orthosis. However, compliance has been shown to be an issue with such devices.Objectives:The aim of this study was to identify the effects of a new design of knee unloader orthosis on specific gait parameters in patients with mild-to-moderate medial knee osteoarthritis.Methods:The gait of seven patients was assessed in two conditions: without an orthosis and when wearing a new design of unloader knee orthosis. Gait analysis was performed to determine alterations to the adduction moment, speed of walking, step length, cadence and knee sagittal plane range of motion during ambulation for the two test conditions.Results:The knee adduction moment was significantly reduced ( p = 0.001), and the speed of walking significantly increased ( p < 0.001) when wearing the orthosis. However, a reduction in knee range of motion ( p = 0.002) and an increase in step length ( p < 0.001) were observed with the orthosis donned. Cadence was not significantly altered ( p = 0.504).Conclusion:The use of a new design of unloader knee orthosis as a conservative treatment approach for patients with mild-to-moderate medial compartment osteoarthritis appears warranted.Clinical relevanceVarious conservative modalities have been used to reduce pain and improve function in medial compartment osteoarthritis. A new design of an unloader knee orthosis has been developed and is shown to have immediate benefits in patients with mild medial knee osteoarthritis.
