Background and Objective: One of the most common malalignments of the knee joint is valgus. This study was done to determine the effect of using graded knee brace at two angles of 60 and 30 degrees on the ground reaction force components in males with genu valgus during landing.
Methods: This clinical trial study was done on twenty males with genu valgus with age range of 21.70±2.12 years. The graded knee brace was used in two flexion angles of 60 and 30 degrees. Landing from a platform with 40 cm height on a force plate was done during three conditions including without brace, with a brace at flexion angles of 30 and 60 degrees.
Results: A significant reduction was observed in the vertical force during contact phase while landing with brace at a 60-degree angle compared with landing without brace by 15.21% (P<0.05). Also, the peak of medio-lateral force during the heel contact phase while landing with knee brace at 30 degree was significantly greater than that landing with knee brace at 60 degree by 27.18 % (P<0.05).
Conclusion: By reducing the knee flexion angle, the forces of the lower extremities increase and this issue could possibly increase the risk of injury in the knee joint. Therefore, the use of this type of brace is recommended for individuals with genu valgum at a 60 degrees limiting angle.
