Purpose. In the last few years, evidence has emerged to support the possible association between increased BMI and susceptibility to some musculoskeletal diseases. We systematically review the literature to clarify whether obesity is a risk factor for the onset of tendinopathy. Methods. We searched PubMed, Cochrane Central, and Embase Biomedical databases using the keywords “obesity,” “overweight,” and “body mass index” linked in different combinations with the terms “tendinopathy,” “tendinitis,” “tendinosis,” “rotator cuff,” “epicondylitis,” “wrist,” “patellar,” “quadriceps,” “Achilles,” “Plantar Fascia,” and “tendon.” Results. Fifteen studies were included. No level I study on this subject was available, and the results provided are ambiguous. However, all the 5 level II studies report the association between obesity measured in terms of BMI and tendon conditions, with OR ranging between 1.9 (95% CI: 1.1–2.2) and 5.6 (1.9–16.6). Conclusions. The best evidence available to date indicates that obesity is a risk factor for tendinopathy. Nevertheless, further studies should be performed to establish the real strength of the association for each type of tendinopathy, especially because the design of the published studies does not allow identifying a precise cause-effect relationship and the specific role of obesity independently of other metabolic conditions.

Remplissage is a safe, relatively short procedure that allows the surgeon to address large humeral defects with a low postoperative recurrence rate. Humeral head large defects predispose to recurrent instability of the shoulder and deserve surgical management.

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.

Cartilage defects represent a common problem in orthopaedic practice. Predisposing factors include traumas, inflammatory conditions, and biomechanics alterations. Conservative management of cartilage defects often fails, and patients with this lesions may need surgical intervention. Several treatment strategies have been proposed, although only surgery has been proved to be predictably effective. Usually, in focal cartilage defects without a stable fibrocartilaginous repair tissue formed, surgeons try to promote a natural fibrocartilaginous response by using marrow stimulating techniques, such as microfracture, abrasion arthroplasty, and Pridie drilling, with the aim of reducing swelling and pain and improving joint function of the patients. These procedures have demonstrated to be clinically useful and are usually considered as first-line treatment for focal cartilage defects. However, fibrocartilage presents inferior mechanical and biochemical properties compared to normal hyaline articular cartilage, characterized by poor organization, significant amounts of collagen type I, and an increased susceptibility to injury, which ultimately leads to premature osteoarthritis (OA). Therefore, the aim of future therapeutic strategies for articular cartilage regeneration is to obtain a hyaline-like cartilage repair tissue by transplantation of tissues or cells. Further studies are required to clarify the role of gene therapy and mesenchimal stem cells for management of cartilage lesions.

In selected patients at a high risk of shoulder stiffness and therefore necessitating accelerated postoperative rehabilitation, DR repair of the RC could lower retear rates.

Intervertebral disc degeneration (IVD) is a frequent pathological condition. Conservative management often fails, and patients with IVD degeneration may require surgical intervention. Several treatment strategies have been proposed, although only surgical discectomy and arthrodesis have been proved to be predictably effective. The aim of biological strategies is to prevent and manage IVD degeneration, improve the function, the anabolic and reparative capabilities of the nucleus pulposus and annulus fibrosus cells, and inhibit matrix degradation. At present, clinical applications are still in their infancy. Further studies are required to clarify the role of mesenchymal stem cells and gene therapy for the prevention and treatment of IVD degeneration.
