膝屈曲位での動作で疼痛が生じていた内側半月板損傷の一症例

抄録

We performed physical therapy a softball player with a medial meniscus injury. She had difficulty in the movement of knee bending due to pain at the anteromedial part of the right knee. We observed the following mal-alignment in her movement with knee bending: pelvic inclination, valgus of the knee, external rotation of the tibia and eversion of the foot. The main problem in this case was the weakness of vastus medialis and abdominis muscles in movement with knee bending and deficiency of improvement in dynamic alignment. In physical therapy, we prescribed the practice of movement paying attention to the mal-alignment and muscle contraction. As a result of physical therapy, dynamic alignment of pelvic inclination, valgus of the knee, external rotation of the tibia and eversion of the foot were reduced, and muscle strength in the movement of knee bending and pain at the anteromedial part of right knee were relieved. The patient was able to resume the movement of knee bending during softball.
