Abstract :

One of the main problems in sports medicine in today’s world is knee injuries. Champions of various sports fields often suffer from common knee injuries, such as injuries to the anterior cruciate ligament, middle cruciate ligament, medial collateral ligament of the knee, or meniscus. In this paper, a knee brace for general applications is modeled and its stress and strain analysis is calculated with the help of software. First, the displacement of the knee brace with ABAQUS software is investigated. By moving toward the top of the knee brace, the amount of displacement decreases. So that at least the amount of displacement is in the upper part of the knee brace. In the next part, the amount of strain and strain for this knee brace is investigated. The amount of stress in the upper part of the knee brace is higher than in other places. Additionally, the amount of strain for this knee brace is determined, the knee brace in the upper part, on the inner side of the knee brace, bears more strain. The results show that this knee brace can be easily produced and considered for different applications.
