Abstract

The knee is one of the most vulnerable structures to suffer from anterior cruciate ligament (ACL) or posterior cruciate ligament (PCL) injuries. These injuries, which account for between 50% and 90% of knee injuries, at least in the sports context, cause pain, swelling, and muscle weakness. In some cases, they require surgical procedures such as arthroscopic surgery, which, although effective, presents challenges related to high costs, risks associated with the use of grafts, and a long recovery process. The use of knee orthoses, combined with physical rehabilitation, presents a less invasive and cost-effective alternative, especially for less severe injuries. The purpose of this study is to design a low-cost, effective, and accessible knee orthosis prototype. To achieve this, experts in orthopedics, biomechanics, and athletes with knee injuries were consulted to gather information on their experiences and needs. The results revealed a demand for more accessible orthoses tailored to the specific needs of athletes, as well as dissatisfaction with the current commercial options. Based on the research and analysis of the surveys, materials such as neoprene and thermoplastics were identified, offering stability, support, and an ergonomic design suitable for athletes.
