Categorization of Different Clamp Types Used For The Endurance Test of Human Grafts – A Systematic Review
Abstract BackgroundThe use of tendon allografts for orthopedic repair has gained wide acceptance in recent years, most notably in anterior cruciate tendon reconstruction. Multiple studies support the use of tendon allografts and the benefits of its use are well accepted and understood. One of the important criteria of the use of tendon allografts is statistically similar histological and biomechanical properties to autographs. Five major scientific literature databases (Web of Science, Science Direct, Scopus, PloS ONE, Hindawi) and additional sources were used. ResultsThe objective of this systematic literature review is to investigate and categorize existing clamps used in the determination of the biomechanical properties (maximum load, maximum strength, modulus of elasticity, ultimate strain, stiffness) of tendons. Studies had to use an endurance test of tendons and clamps in detail. The database search and additional sources resulted in 274 records. 216 records eliminated during the screening for various reasons. The number of articles used in the final synthesis was 58. Search for publications dated between 1991 and Oct 31st, 2020. A variety of clamps for use during the endurance test of tendons were identified and categorized according to the temperature used during the measurement. The clamps are divided into three groups: room temperature, cooled or heated clamps.ConclusionsOn the basis of the systematic literature review, mechanical parameters determined by usage with cooled clamps proved to be more reliable than with those at room temperature and with heated clamps. The main advantage of the cooled clamps is that there is no limit to the type and length of the tendon. This study provides an overview of clamps and does not represent the modernity of any method.
