Is hip resurfacing done with cobalt-chrome alloy?

In hip resurfacing, the damaged surface of the ball of the hip is shaped and covered rather than removing the entire femoral head. A matching component is placed in the socket. Cobalt-chrome alloy is used in some resurfacing systems because it can provide a hard, smooth bearing surface, but an implant is selected as a complete system rather than by material name alone.

The operation is not suitable for every hip problem or every patient. Bone strength, hip shape, activity goals, sex, age, kidney health and metal sensitivity may influence the discussion. Ask the surgeon which bearing pair and implant design are being proposed.

Take your health history and current medicines to the orthopaedic consultation. Tell the surgeon about metal allergies, skin reactions, kidney disease, pregnancy plans and previous hip procedures. Ask how the proposed implant is monitored, what activities are expected during recovery, and which alternative treatments could address your symptoms.

After surgery, follow the wound, walking and exercise instructions. Attend planned reviews and report new groin pain, swelling, clicking, reduced movement or a change in walking rather than trying to diagnose the cause yourself.

After hip resurfacing, seek urgent help for chest pain, severe breathlessness, fainting, sudden inability to bear weight, a leg that appears shortened or rotated, or new foot numbness. Contact the surgical team promptly for fever, wound drainage, spreading redness, increasing pain, new swelling, or a new rash or hearing change after symptoms around the implant.

What implant system and bearing surfaces are planned? Why is resurfacing appropriate for my hip and bone quality? What are the alternatives? How would metal sensitivity or kidney disease affect the plan? What symptoms should prompt a review, and how will the implant be followed over time?
