Investigation of stress distribution around Supraspinatus tendon injurieswith and without PU scaffold

Tendon ruptures, a prevalent condition with significant consequences, lead to substantial disabilityand reduced quality of life. Tendon repair is challenging, and the risk of rerupture is high. PU tissuescaffolds have emerged as a novel therapeutic approach to enhance tendon wound healing andmitigate rerupture risk. This study investigates the effects of PU tissue scaffolds on stress distributionwithin the tendon wound area using numerical simulations. Findings reveal that PU tissue scaffolds,particularly in the horizontal orientation, can substantially reduce stress in the wound region andprevent stress concentration, the primary culprit behind tendon rerupture.
