Abstract: (326 Views)
Meniscus tears, a prevalent knee joint injury, can significantly hinder joint functionality. Thus, the control of meniscus tears holds significant importance in preserving the joint's regular functionality. A non-invasive approach involves the recommendation of off-loading insoles; which therapists often prescribe based on their clinical experience. Based on the variety of meniscus tear types, it is essential to assess the effectiveness of different insoles when interacting with these distinct tears. This evaluation can be achieved through biomechanical investigations. To address this requirement, the present study utilized medical imaging to establish the precise lower limb geometry. To refine the acquired geometry, both longitudinal and radial tears were applied to the meniscus's geometry. The subsequent phase entails reconstructing the design of three off-loading insole models currently available in the Iranian market. The outcomes of these models demonstrate that the three-layer insole without honeycombs leads to a stress reduction of 1.1% at the apex of the radial tear. When dealing with a longitudinal tear situated on the inner meniscus, the application of a three-layer insole equipped with a honeycomb structure results in a 15% stress reduction. Utilizing a single-layer silicone insole results in an 8% decrease in stress on the external meniscus during longitudinal tears. Hence, the three-layer insole incorporating a honeycomb design is effective for managing longitudinal tears on the inner meniscus. Moreover, the research outcomes indicate that, when comparing the two tear types, longitudinal tears carry a greater risk than radial tears, exhibiting an increased likelihood of worsening.
