Background: Proprioceptive information plays an important role in joint stabilization, body coordination and proper function. Flatfoot affect the mechanics of lower limb as foot pronation causes tibial internal rotation, which causes knee valgus. Flat foot deformity may alter the proprioception of knee joint and that may predispose to joint injury. Objective: to investigate the effect of bilateral flexible second degree flatfoot on weight bearing and non-weight bearing knee proprioception. Methods: Thirty-two males and females subjects with age ranged from 18-25 years old were assigned into two equal groups, Group A (normal group) and group B (flat foot group). Lateral weight bearing radiographs were performed bilaterally for each subject in both groups to determine the degree of flat foot by measuring the talus first metatarsal angle and to confirm normal subjects. Active repositioning test of knee flexion was measured in weight bearing and non-weight bearing state by digital goniometer to assess proprioception in form of joint reposition error of knee joint. Results: MANOVA revealed that there was no statistically significant difference in reposition error of knee joint in the flatfoot group compared with control group in weight bearing state as p value {u2265} 0.05. There was statistically significant difference in reposition error of knee joint in the flatfoot group compared with control group in non-weight bearing state as p value {u2264} 0.0
