Various techniques for the fixation of unstable osteochondral fragments have been used over the years, each with associated advantages and disadvantages, and differing clinical outcomes. However, the literature on the treatment of this type of injury in the adolescent and young adult population is scarce and involves small case series. Failure to treat these injuries can lead to serious consequences such as chronic pain, residual joint stiffness, and the development of early osteoarthritis, necessitating more invasive and burdensome interventions for the national health system, such as prosthetic replacements or osteotomies. Due to the lack of real consensus within the scientific community regarding the ideal treatment for these patients and the insufficient medium/long-term follow-up data on the effects of these injuries on articular cartilage in young patients, this study aims to evaluate the clinical and radiological conditions of patients undergoing osteochondral fragment fixation using the same surgical technique (fixation with resorbable screws performed arthroscopically or via open surgery depending on the lesion's location) in order to clarify preventive measures against cartilage degeneration following these injuries, which are very common in adolescence.
