Analysis of forces in knee joints of top football players and futsal players in different types of jumps

Abstract

In this paper, we will consider the forces in knee joints in football and futsal players during different types of jumps. We will consider two types of jumps: jumps with flywheel and jumps without flywheel. This study has two main aims. The first aim is to compare the knee joint forces in football players and futsal players during different types of jumps. The second aim is to determine the distribution of deformation and stress in menisci of the knee joints in football and futsal players. Professional futsal players performed jumps that were analyzed using a force plate and high-speed video camera system. For this purpose, a 3D model of the human knee joint was developed from medical scans. The 3D model of the human knee joint consisted of femur, fibula, tibia, articular cartilage, ligaments and menisci. Loads and material characteristics were adopted from the literature. The use of finite elements analysis enabled us to gain better understanding of the distribution of deformation and stress in specific parts of the knee joint, with the special focus on the menisci.
