KC Combo

Knee Control Orthosis

Practitioners managing patients with knee flexion instability in stance are often faced with the dilemma of whether the patient needs a knee ankle foot orthosis or just an AFO to correct the instability. Those with poor quadriceps may experience knee flexion in stance, especially if they lack strength and endurance. Locking up the knee all the time may interfere with the patient’s ability to actively strengthen the muscles that will provide long term stability.
The KC Combo provides opportunities for developing knee control with the AFO alone, or with the attached knee component to provide more proximal alignment and stability.
