How does hip resurfacing work?

During the operation, the surgeon removes damaged surface bone and cartilage from the ball of the hip but keeps most of the femoral head and neck. A shaped cap is fixed over the prepared ball. The worn socket is also prepared and lined with a cup, allowing the capped ball to move within it. The components are designed to create a smoother joint surface and reduce pain from bone-on-bone contact.

Hip resurfacing is not suitable for every person. Bone quality, the shape of the hip, age, activity goals and the reason for joint damage all affect the discussion. Hip osteoarthritis can damage both joint surfaces, but the operation chosen depends on the individual assessment.

Before surgery, review medicines, dental or skin infections and the exercises recommended for your muscles. Afterward, use the walking aid and weight-bearing instructions supplied by your team. Build activity gradually through rehabilitation, paying attention to hip strength, balance and controlled movement. Avoid high-impact or twisting activity until your surgeon confirms that the hip has healed and your movement is safe.

Contact your care team for increasing wound redness, fluid, fever, worsening groin pain or a new change in walking ability. Urgent care is needed for sudden breathlessness, chest pain, a markedly swollen calf, or a leg that becomes cold or numb. New persistent clicking or pain after activity should be assessed rather than ignored.

Ask why resurfacing is being considered, how your bone quality affects suitability, which alloy is used, and how the choice compares with total hip replacement. Discuss expected weight-bearing, activity limits, follow-up imaging and signs of implant trouble.
