Ceramic hip resurfacing (H1)

• For selected active women and men with hip osteoarthritis and good bone quality
• Operating time: approximately 60–90 minutes through a muscle-sparing anterior approach
• Hospital stay: 3–5 days
• Cycling and swimming after around six weeks; running and ball sports after around six months

Recovery and return to sport depend on your bone quality, surgical findings and individual progress; these timings are not guarantees.

H1 ceramic hip resurfacing was introduced in Greifswald in March 2026. It adds an option for selected patients when preserving the natural joint is no longer appropriate.

A conventional hip replacement removes the femoral head and places a stem in the thigh bone. Resurfacing retains the femoral head and neck, fitting a ceramic cap over the head much like a crown over a tooth.

• More of your own bone is preserved.
• The large head follows your natural anatomy and may contribute to stability, although dislocation cannot be ruled out.
• Your hip shape is largely preserved; leg length is considered during planning.
• If revision is needed later, conversion to a conventional hip replacement is usually possible.

A 40-year-old woman with advanced hip osteoarthritis and high activity demands received ceramic hip resurfacing. Her preoperative X-ray shows loss of cartilage and narrowing of the left joint space.

The postoperative image shows the retained femoral head and neck with a ceramic cap replacing the joint surface. She can bear weight from the start and gradually rebuild sporting activity.

Earlier resurfacing systems used metal-on-metal bearings, which could release metal wear particles and ions and cause local tissue reactions. H1 has two ceramic bearing surfaces: the cap moves inside a matching ceramic shell.

This avoids a metal-on-metal bearing, but it does not eliminate risk. Ceramic can produce noise and can rarely fracture.

• No metal-on-metal contact at the bearing
• Very low ceramic wear
• The ceramic material has also been used in conventional hip replacements for many years

Ceramic resurfacing can be suitable for active people with hip osteoarthritis, including arthritis caused by hip dysplasia. Bone quality and overall fitness matter more than age alone.

Women and smaller hips are not automatically excluded; small implant sizes are available.

It is not suitable when bone is too weak because of osteoporosis or the femoral head is extensively damaged. We assess your X-rays together and recommend a conventional replacement if that is the better option.

• Direct anterior approach (DAA): muscles are moved aside rather than detached.
• Detailed individual planning, with particular attention to implant positioning.
• Operating time: approximately 60–90 minutes.
• Hospital stay: 3–5 days.

You may bear weight from the start as pain allows. Running and jumping are delayed while the bone adapts to the implant.

Weeks 1–6

Protection: wound healing, mobility, walking with crutches, everyday movements and home exercises.

Week 7 to month 3

Strengthening: walking, cycling, swimming and light strength training; restoring balance and reducing a limp.

Months 4–6

Progression: hiking, cross-trainer and initial short runs; rebuilding equal leg strength and single-leg stability.

From month 7

Return to sport, including jogging, tennis, ball sports and skiing, according to your individual recovery.

The femoral neck needs several months to adapt to its new loading. Your surgeon and physiotherapist tailor progression to your bone quality and follow-up findings.

Physiotherapy supports safe walking, mobility and gradual strengthening. Clinical and X-ray reviews are part of aftercare; you receive your personal follow-up plan on discharge.

Crutches are generally used for 4–6 weeks. Driving is usually possible around six weeks when you can walk safely without crutches. Office work is often possible after 3–6 weeks and heavy physical work after around three months.

New groin pain or a returning limp in the first months should be assessed promptly.

• Hip resurfacing has been used for over 20 years. With appropriate patient selection, more than 95% of joints in earlier resurfacing series remain functioning after 15–20 years.
• In an international ceramic resurfacing study of more than 600 patients, 98% of joints were functioning after five years, with similar results in women and men.
• Almost one in two patients participates in running or jumping sports two years after surgery.

The ceramic version has been available since 2017, so 15- or 20-year results do not yet exist for it. Earlier resurfacing results cannot be transferred directly to H1. International findings are not Greifswald's own long-term outcomes, and none of these figures guarantees an individual result.

• General surgical risks, including infection, thrombosis and bleeding
• Rare femoral neck fracture, usually in the first months; conversion to a conventional replacement is then needed
• Loosening of an implant component
• Occasional joint noise and very rare ceramic fracture
• Usually temporary numbness on the outer thigh from irritation of a skin nerve
