Mechanical Properties Of Achilles And Patellar Tendons: A Comprehensive Analysis
Main Article Content
Abstract
Background: Tendons, such as the Achilles and Patellar tendons, play a vital role in facilitating movement and providing structural support to the musculoskeletal system. This study aimed to comprehensively analyze the mechanical properties of Achilles and Patellar tendons and investigate their relationship with age.
Methods: Experimental measurements of stiffness, elasticity, and tensile strength were conducted on tendon samples. Descriptive statistics and correlation analysis were performed to explore the associations between age and tendon mechanics. A review of relevant literature on tendon biomechanics and aging processes supplemented the experimental findings.
Results: The study revealed significant age-related changes in the mechanical properties of Achilles and Patellar tendons. Descriptive statistics indicated variations in stiffness, elasticity, and tensile strength with advancing age. Correlation analysis demonstrated moderate to strong associations between age and tendon mechanics, with implications for musculoskeletal function and aging-related tissue alterations.
Conclusion: These findings contribute to a deeper understanding of the impact of aging on tendon biomechanics and underscore the importance of considering age-related changes in the assessment and management of tendon health and function.
