Appropriately powered randomized controlled trials reporting clinical and imaging-related outcomes in patients undergoing arthroscopic minimally invasive procedures and meniscal suturing should be performed. Comparing imaging findings of patients undergoing arthroscopic partial and open meniscectomy, a lower incidence of knee osteoarthritic evolution was detected after arthroscopy. The amount of removed meniscus is the most important predictor factor for the development of osteoarthritis. Minimally invasive procedures seem to reduce the incidence of long-term osteoarthritic changes of the knee compared with more invasive open and or arthroscopic procedures.

When faced with ACL deficiency, physiological age, condition of the knee at the time of examination, life expectancy and activity level are probably more important than chronologic age. In the present study, arthroscopic surgery for the management of ACL tear and secondary lesions provides comparable clinical outcomes in middle-aged patients and in patients aged below 30.

Further studies are needed to produce clear guidelines to define the best choice in terms of clinical outcomes, function and complications.

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.

Purpose Microfractures at the footprint may be a potential additional source of growth factor and enhance the tendon healing at the bone-tendon junction when repairing rotator cuff tears. Methods Fifty-seven patients who underwent shoulder arthroscopy for repair of complete rotator cuff tears were randomly divided into two groups, using a block randomisation procedure. Patients underwent microfracture at the footprint in the treatment group. The patients in the control group (n=29) did not receive that treatment. All patients had the same post-operative rehabilitation protocol. Results The two groups were homogeneous. There was a significant improvement from baseline to the last minimum follow-up of two years. At three months from the index procedure, visual analogue scale (VAS), range of motion (ROM) and University of California at Los Angeles (UCLA) and Constant scores were significantly better in group 1 than in group 2 (P<.05). At the last follow-up (minimum two years), clinical and functional outcomes were further improved in both the groups but inter-group differences were not significant. No technique-related complications were recorded. Conclusions Microfractures at the footprint are simple, safe, inexpensive and effective at producing less pain in the short term in patients who undergo rotator cuff repair, but at two years they do not result in significantly different outcomes, either clinically or at imaging, compared to traditional rotator cuff repair.
