  • Purpose: The biomechanics and kinematics of knee joint were reviewed in this article. And then the common sports injuries were presented. Anatomy and Kinetics: None of the pairs of bearing surfaces in the knee joint is exactly congruent This allows the knee six degrees of freedom of motion. Tibiofemoral Kinematics: In flexion and extension, the axis of motion is not perpendicular to the medial-lateral plane of the joint, nor is it perpendicular to the axis of longitudinal rotation. This results in coupled varus angulation and internal rotation with flexion and in valgus angulation and external rotation with extension. Patellofemoral Articulation: Loads across the patellofemoral joint are indirectly related to the angle of knee flexion and directly related to the force generated within the quadriceps mechanism. Fractures of the Patella: Nonoperative treatment is indicated if the extensor mechanism is intact and if displacement of fragment is minimal. The specific type of internal fixation depends on the fracture pattern. It is important to repair retinaculum. Acute and Recurrent Patellar Instability: The degree of dysplasia and the extent of the instability play a large part in determining the success of nonoperative treatment. Patients who experience recurrent dislocations and patients with major anatomic variations require surgery to minimize their instability. Sports Injuries in School-age Atheletes: Patellar pain in young athletes groups a number of conditions, including Idiopathic Adolescent Anterior Knee Pain, Osgood- Schlatter Disease, and Sinding-Larsen-Johansson Disease.

Effect of Kinesio Taping on Muscular Strength, Power, and Endurance of the Extension and Flexion of the Knee Joint (슬관절 탄력테이핑 적용이 슬관절 굴곡과 신전의 근력, 근파워, 근지구력에 미치는 영향)

  • This study was conducted to verify the effect of elastic-taping on the strength, power, and endurance of muscles. Elastic-taping is widely used in sports for preventing injuries due to flexion and extension of the knee joints. The participants of this study were 10 male college students with no abnormalities in knee flexion and extension movements. The function of flexors and extensors of the knee joint were assessed using the isokinetic muscle function measurement equipment at angular velocities of 60°/sec, 5 times; 180°/sec, 5 times; 240°/sec, 25 times before and after applying Kinesio taping. It was observed that the average power of muscles after application of Kinesio taping during knee extension on the right side was significantly increased at angular velocity of 180°/sec (p=.010). During knee flexion, the average power was significantly increased at the right angular velocity of 180° /sec after Kinesio taping was applied (p=.016). In addition, at an angular velocity of 240°/sec, both left (p=.002) and right (p=.002) sides showed significant increase in total work done. The application of Kinesio taping to the rectus femoris and biceps femoris showed a positive effect on improving muscle power and endurance during knee joint exercise.
