Flat feet
Different degrees of foot arch collapse, easy to cause various complications
Foot varus
The load on the lateral part of the foot causes bone deformation and affects normal growth
Foot valgus
Weight bearing on the medial part of the foot causes bone deformation and affects normal growth
Pigeon toe
Forefoot inward, abnormal gait, resulting in lower leg deformation and knee joint deformation
Toe out
Forefoot outward, abnormal gait, causing leg deformation and knee joint deformation
O legs
Damage to the knee joint tissue, leg, knee deformation, affect leg shape and bone growth
X legs
Damage to the knee joint tissue, leg, knee deformation, affect leg shape and bone growth
