Objective Search and collect the previous relevant literature on the influence of diabetes on the progress of tendinosis,summarize the relevant conclusions and discuss the pathogenesis of diabetes accelerating the progress of tendinosis,mainly including summarizing the biomechanical and histological changes of diseased tendons in diabetes patients,as well as its pathogenesis at the cellular level.Methods This paper reviewed and analyzed the domestic and foreign literature related to dia-betes tendinosis by searching some Chinese and English databases like PubMed,Springer Link,CNKI,Google Academic.Re-sults Most previous studies more support the theory of degeneration as the pathogenesis of tendinosis,but now more and more researchers find that diabetes,as a systemic metabolic disease,can induce the occurrence of tendinosis through a variety of mech-anisms,or aggravate the progress of tendinosis,such as the accumulation of advanced glycation end products(AGEs)at the le-sion site,chronic inflammatory reaction at the lesion site,increased oxidative stress level of tendon cells And changes in the ac-tivities of matrix metalloproteinases and glutamine transaminase.By summarizing and analyzing the various understandings of dia-betes on the pathogenesis of tendinosis proposed by previous researchers,the relationship between diabetes and tendinosis is grad-ually clear.Conclusion As a systemic metabolic disease,diabetes can induce the occurrence of tendinosis or aggravate the pro-gress of tendinosis through a variety of ways and mechanisms.Research and clarification of these ways can provide us with a pow-erful weapon to study and treat tendinosis.However,at present,there are many possible pathogenesis of diabetes tendinosis,which still needs to be studied step by step to further clarify its main pathogenesis.
