How effective is custom orthotics for ankle osteoarthritis?

Ankle osteoarthritis involves changes in the joint surfaces and surrounding tissues. A custom orthotic can alter how the foot meets the ground, spread pressure and support a movement pattern that feels steadier. This may reduce load on a painful part of the ankle during standing or walking. It cannot restore worn cartilage or remove stiffness. Some people need a brace, footwear change, physiotherapy or other treatment when an insert alone does not provide enough support.

Assessment should include ankle movement, foot shape, alignment, balance, footwear and the activities that matter to you. Introduce the device for shorter periods at first, then build use as comfort allows. Check your skin and the way you walk, especially if sensation is reduced. A review can adjust the fit or design and combine the orthotic with ankle mobility, strength and balance work. Persistent pain should prompt reassessment rather than repeated device changes without examination.

Arrange prompt care for a hot, red, suddenly swollen ankle, fever, or inability to bear weight after an injury. Stop using an orthotic and seek advice for skin breakdown, persistent numbness, severe pressure or rapidly worsening pain. New instability or repeated giving way also warrants examination.

Which part of my ankle or foot is receiving too much load? Would an insert, brace or footwear change suit my alignment? How should I break in the device? Which exercises can preserve movement and strength? When should we review its fit and effect on walking?
