Stance-Control Knee–Ankle–Foot Orthoses for People With Knee Instability

Final Recommendation

  • Ontario Health, based on guidance from the Ontario Health Technology Advisory Committee, recommends publicly funding mechanical stance-control knee–ankle–foot orthoses for people with knee instability

Read the final recommendation report

The stability of the knee is reliant on sound anatomical structures as well as an intact nervous system and an adequate muscular system around the knee. Any changes to these systems that cause muscle weakness, or changes in the way the knee works, can lead to pain, falls, and limited mobility. Changes that can cause knee instability include neuromuscular disease, central nervous system conditions, injury, or accident.

For people with knee instability, knee orthosis devices are prescribed to help with standing, walking, and performing tasks. Conventional knee–ankle–foot orthoses provide stability by locking the knee in a fully extended position to keep the leg straight while standing and walking; however, this changes the way a person walks. Stance-control knee–ankle–foot orthoses allow the knee to bend while walking.

This health technology assessment looked at how safe and effective stance-control knee–ankle–foot orthoses are for people with knee instability. It also looked at the budget impact of publicly funding stance-control knee–ankle–foot orthoses. It also considered the experiences, preferences, and values of people with knee instability.
