Technical Information

The Custom moulded Blount’s KAFO has been proven to eliminate the need for surgery in many patients.

The KAFO is designed to be worn for 23 hours each day in order provide maximum correction.

Correction is obtained through a simple three-point pressure system.

The combination of the patented swivel hinge on the posterior calf section and the Positive Track Telescoping Ankle Joint ensures the KAFO is self adjusting during dynamic correction. This effectively controls tibial torsion and aligns the foot.

The Blount’s KAFO orthosis directs the force from the lateral to medial side via a patented swivel hinge and elastic strap on posterior of brace below knee hinge. This allows correction to take place even when child is walking or playing.

Other orthoses used to attempt to control Blount’s disease only work when the knee joint is locked therefore inhibiting normal activity and are often worn only when the child is sleeping.

The Blount’s KAFO does not impede normal walking and play activities.
