Despite the high level achieved in the field of shoulder surgery, a global consensus on rotator cuff tears management is lacking. This work is divided into two main sessions: in the first, we set questions about hot topics involved in the rotator cuff tears, from the etiopathogenesis to the surgical treatment. In the second, we answered these questions by mentioning Evidence Based Medicine. The aim of the present work is to provide easily accessible guidelines: they could be considered as recommendations for a good clinical practice developed through a process of sys- © C I C E d i z i o n i I n t e r n a z i o n a l i tematic review of the literature and expert opinion, in order to improve the quality of care and rationalize the use of resources. KEY WORDS: rotator cuff tears, Guidelines. IntroductionThe pathologies of the rotator cuff are common and they can be considered as a natural decline of the muscletendon unit in aging with statistically significant increase in frequency after 50 years. The painful shoulder is related in 30-70% of cases to disorders of the rotator cuff. The incidence of rotator cuff tears varies between 5 and 40%, although it is very difficult to establish the real incidence of these lesions, which are often asymptomatic. Currently, the pathology of the rotator cuff is considered to be multifactorial, because extrinsic and intrinsic factors play important roles, although it remains unclear the specific weight of each of these factors (Tab. 1). and often increased in number. staining eosinophilic There is a loss of orientation of homogeneous preparation the cores in relation to the bundles with hematoxylin/eosin. of collagen fibers.

SummaryPrimary traumatic patellar dislocation is common, particularly in young active individuals. A consensus on its management is still lacking. The present work provides easily accessible guidelines to be considered as recommendations for a good clinical practice developed through a process of systematic review of the literature and expert opinion, to improve the quality of care and rationalize the use of resources. Level of evidence: Ia.
