Workflow assessing the effect of Achilles tendon rupture on gait function and metatarsal stress: Combined musculoskeletal modeling and finite element analysis

Abstract

Achilles tendon rupture (ATR) incidence has increased among badminton players in recent years. The foot internal stress was hard to obtain through experimental testing. The purpose of the current research is to develop a methodology that could improve the finite element model derived foot internal stress prediction for ATR clinical and rehabilitation applications. A subject-specific musculoskeletal model was combined with a 3D finite element model to predict the metatarsal stress. The 80% point during the push-off phase of walking was selected for the comparing between injured and uninjured sides. The surgical repaired Achilles tendon (AT) after 12 months was elongated by 5.5% than the uninjured tendon. At 80% point of stance phase, the ankle plantarflexion angle and AT force decreased by 39.6% and 21.9% on the injured side, respectively. The foot inversion degree increased by 22.9% and was accompanied by the redistribution of metatarsals von Mises stress. The stresses on the fourth and fifth metatarsals were increased by 59.5% and 85.9% on the injured side. The workflow is available to assess musculoskeletal disorders and obtain foot internal stress after ATR. The decreased ankle plantar flexor force may be affected by triceps surae muscle atrophy and weakened force transmission ability of elongated AT. The increased von Mises stress on fourth and fifth metatarsals accompanied by higher foot inversion may increase the ankle lateral sprain injury risk.

Biomechanics research on laterality effect between dominant and non-dominant during double roundhouse kick in the competitive taekwondo

“…The following deficiencies could be detectable from the present scrutiny: only data from two aerial strikes were selected for analysis, and no data analysis was conducted for the initiation and ending phases, mainly because the distance and amplitude of the subject's strikes were affected to some extent by the force measuring table and the experimental dummy. Meanwhile, the potential impact of various states (such as non-dominant and dominant legs) on sports injuries can be further analyzed; for this purpose, musculoskeletal finite element modeling can be employed to analyze the stress and strain effects on the human body, revealing potential sports injury situations [ [58] , [59] , [60] ].…”

Case study: The influence of Achilles tendon rupture on knee joint stress during counter-movement jump – Combining musculoskeletal modeling and finite element analysis

“…According to research findings, ATR has been shown to result in reduced posterior muscle strength and tendon length [ 10 , 12 , 13 , 17 , 19 , 26 , 27 ], which, in turn, may lead to a decrease in plantarflexion range and an increase in dorsiflexion range [ [14] , [15] , [16] , 28 ]. Consequently, the individual's jumping ability may be negatively affected [ 24 , 25 , 29 , 30 ].…”

“…Owing to the limited feasibility of directly measuring tibiofemoral forces, a commonly employed approach is to combine medical imaging, musculoskeletal modelling [ 41 , 42 ], and finite elements analysis [ 28 , 43 ]. However, relatively few studies have examined tibiofemoral forces during countermovement jump (CMJ) in patients with ATR [ 44 ].…”
