Overview
Brief Summary
Meniscal lesions represent the most frequently encountered joint pathology in the adult population and can cause pain symptoms, mechanical blockages, and recurrent effusions. The treatment of these lesions has progressively evolved from meniscectomy (removal of the damaged meniscal tissue) to the use of meniscal sutures (where possible) to preserve as much meniscus as possible. Numerous studies have demonstrated a correlation between the amount of meniscus removed and the future onset of osteoarthritis.
However, in some cases, especially in the presence of complex and/or chronic lesions, meniscectomy remains the only viable surgical option. Over time, months or years later, a subgroup of patients may develop symptoms such as pain, joint swelling, and mechanical overload of the compartment that underwent meniscectomy, a condition known as post-meniscectomy syndrome..A portion of these patients will later develop knee osteoarthritis and require invasive procedures such as partial or total knee replacement.
In an attempt to treat this condition, scaffolds-collagen implants-have been developed and are arthroscopically implanted in the knee with the aim of functionally replacing the tissue removed during surgery. The goal is to reduce the incidence of long-term osteoarthritis and, consequently, the need for more invasive procedures. To date, no study has definitively demonstrated the real efficacy of these scaffolds (CMI), particularly regarding chondroprotection and the long-term onset of osteoarthritis.

Outcomes
Primary Outcomes
International Knee Documentation Committee (IKDC):
Time Frame: 10 years after surgery
The IKDC form is a subjective knee evaluation module that reflects the limitations on activities the individual can perform in daily life and sports, as well as the presence or absence of symptoms. There are three main domains in the IKDC evaluation form: Symptoms, which include pain, stiffness, swelling, and a sensation of locking; Sports and daily activities; Current knee function and function prior to injury. The questionnaire consists of 10 questions: seven items investigate the patient\'s symptoms, one item is focused on sports participation, one item-composed of 9 points-addresses the difficulties the patient experiences in performing daily life activities, and the last item measures the current functionality of the knee. The score ranges from 0 to 100, with 100 representing the absence of limitations and symptoms, indicating an excellent outcome; the further away from this score, the worse the result, which can be divided into four groups
