Lateral wedges in knee osteoarthritis: What are their immediate clinical and biomechanical effects and can these predict a three‐month clinical outcome?

Abstract

Objective. To assess immediate effects of laterally wedged insoles on walking pain, external knee adduction moment, and static alignment, and whether these immediate effects together with age, body mass index, and disease severity predict clinical outcome after 3 months of wearing insoles in medial knee osteoarthritis. Conclusion. Lateral wedges immediately reduced knee adduction moment and walking pain but had no effect on static alignment. Although some parameters predicted clinical outcome, these explained only one-third of the variance, suggesting that other unknown factors are also important.

Self‐reported knee and foot alignments in early adult life and risk of osteoarthritis

“…This supports the hypothesis that possible strategies to reduce the incidence of OA from knee malalignment could include orthotic footwear (31) or the deliberate adaption of a toe-out foot alignment during gait (19,20). Knee adduction moments can be modified by orthoses (32)(33)(34), variable-stiffness shoes (35), leg braces (36), and reduced walking velocity (37). Knee malalignment may be associated with alterations in foot angle in early adult life (38).…”

Trunk lean gait modification and knee joint load in people with medial knee osteoarthritis: The effect of varying trunk lean angles

“…A Vicon motion analysis system captured gait kinematics using 8 MX cameras recording at 120 Hz, which was integrated with 3 force platforms (Advanced Mechanical Technology) embedded in the laboratory floor to collect ground reaction force data at 1,200 Hz. The standard Plug-In-Gait lower body marker set (Vicon) was used, with 20 retro-reflective markers adhered to anatomic landmarks (28). Medial knee and ankle markers were included during an initial static standing trial to determine positioning of knee and ankle joint centers.…”

The relationship between patellofemoral and tibiofemoral morphology and gait biomechanics following arthroscopic partial medial meniscectomy

“…This expansion may 15 reflect structural changes in the bone, as have been observed in the arthroscopic 16 partial medial meniscectomy population [39]. This may affect the mechanical 17 properties of the bone, and therefore the cartilage, leading to development of 18 osteoarthritis [7,9,37]. As the follow up period in this study is less than the study 19 by Miyazaki and colleagues [27] we may be observing early morphological 20 changes which have the potential to progress to medial tibiofemoral osteoarthritis, 21 however further work is needed.…”
