Abstract

Variations in toe box space (TBS) of shoes during stop-jumping landings may increase knee injury risk, especially patellofemoral pain syndrome (PFPS). This study aimed to investigate the potential influence of TBS on PFPS during stop-jumping landings. Twenty-eight male basketball athletes were recruited, wearing tight-fitting (TF) and loose-fitting (LF) shoes. Three-dimensional patellar displacement was measured using a high-speed dual fluoroscopic imaging system (DFIS). An integrated foot-ankle-shoe-knee finite element model was used to estimate internal knee stresses. The TF group demonstrated a restricted ankle dorsiflexion range of motion (p < 0.001) and increased knee adduction angle and moment (p < 0.001). Earlier activation of vastus lateralis (VL) relative to vastus medialis (VM) in the TF group contributed to greater lateral patellar displacement and higher Von-Mises stresses in the lateral patella. TF shoes may cause abnormal patellar tracking, elevating the likelihood of PFPS. This study may offer new insights into basketball footwear selection and theoretical support for reducing the risk of PFPS.

鞋的缓冲空间会影响髌骨痛的风险吗？基于综合有限元模型的研究

在停止跳跃着陆时，鞋子的脚趾盒空间（TBS）的变化可能会增加膝关节损伤的风险，特别是髌骨股痛综合征（PFPS）。本研究旨在探讨TBS对停跳着陆时PFPS的潜在影响。招募了28名男子篮球运动员，他们穿着紧身（TF）和宽松（LF）鞋。采用高速双透视成像系统（DFIS）测量三维髌骨位移。采用足-踝-鞋-膝一体化有限元模型估算膝关节内应力。TF组踝关节背屈活动范围受限（p < 0.001），膝关节内收角度和力矩增加（p < 0.001）。在TF组中，相对于股内侧肌（VM），股外侧肌（VL）的激活更早，导致髌骨外侧移位更大，髌骨外侧的Von-Mises应力更高。TF鞋可能导致异常髌骨追踪，增加PFPS的可能性。本研究可能为篮球鞋的选择提供新的见解，并为降低PFPS的风险提供理论支持。

期刊介绍： Science has many big remaining questions. To address them, we will need to work collaboratively and across disciplines. The goal of iScience is to help fuel that type of interdisciplinary thinking. iScience is a new open-access journal from Cell Press that provides a platform for original research in the life, physical, and earth sciences. The primary criterion for publication in iScience is a significant contribution to a relevant field combined with robust results and underlying methodology. The advances appearing in iScience include both fundamental and applied investigations across this interdisciplinary range of topic areas. To support transparency in scientific investigation, we are happy to consider replication studies and papers that describe negative results. We know you want your work to be published quickly and to be widely visible within your community and beyond. With the strong international reputation of Cell Press behind it, publication in iScience will help your work garner the attention and recognition it merits. Like all Cell Press journals, iScience prioritizes rapid publication. Our editorial team pays special attention to high-quality author service and to efficient, clear-cut decisions based on the information available within the manuscript. iScience taps into the expertise across Cell Press journals and selected partners to inform our editorial decisions and help publish your science in a timely and seamless way.
