Polyurethane Meniscus Implant: Technique

The treatment of irreparable meniscal tears remains a major challenge for the orthopaedic community today. Removal of all or part of the meniscus eventually leads to degenerative changes of the articular cartilage and subsequent clinical symptoms [5]. The current treatment of choice for irreparable meniscus tears is partial meniscectomy, which aims to remove only the pathologic or torn tissue, thereby minimising risk to the articular cartilage. Total meniscectomy is now almost completely obsolete; however, it still remains necessary for large irreparable tears [5]. The use of meniscal allografts has proved promising in patients with meniscus tissue loss; however, it is generally used only in patients who have undergone total or subtotal meniscectomy [5].
