Obesity is a major public health issue, as incidence is rising in all developed countries, although the proportion is lower in Europe than in the U.S. Over and above the metabolic consequences and increased risk of diabetes, cardiovascular pathology and certain forms of cancer, the present study focuses on osteoarticular risk, and in particular on pathologies manageable by arthroscopy. It also analyzes results and complications specific to arthroscopy in these indications. Meniscal and ligamentous pathologies of the knee, rotator-cuff pathology in the shoulder and tendon pathology in the elbow were not significantly elevated, although a trend emerged. In contrast, there was significant elevation of Achilles and plantar aponeurosis pathology. In terms of postoperative complications, thromboembolic risk was elevated, but there were not significantly more complications specific to arthroscopy. Finally, subjective results were comparable to those for non-obese patients.Review.
