3.When walking on the ground, the brace should be locked in the fully extended position, and the weight of the affected limb should be gradually increased from 1/4 to 1/3 or 1/2 of the body weight.
4.Lock the brace in the fully extended position during sleep.
2~4 weeks
1.Flexion range up to 120° at the end of the fourth week.
2.Partial weight-bearing squatting and brisk walking.
3.With full weight-bearing, the affected limb can be removed from the abduction only when there is no pain during unilateral weight-bearing.
