MOVE-HIP: Ceramic Hip Resurfacing Versus Total Hip Arthroplasty Using Activity Monitoring (MOVE-HIP)

21. september 2026 opdateret af: Olof Skoldenberg, Danderyd Hospital

A Pragmatic, Multicenter, Patient-Blinded, Preference-Tolerant Randomized Clinical Trial Comparing Ceramic Hip Resurfacing With Total Hip Arthroplasty Using Activity Monitoring

MOVE-HIP is a pragmatic, multicenter randomized clinical trial comparing ceramic hip resurfacing arthroplasty with contemporary total hip arthroplasty in adults with symptomatic hip osteoarthritis who are considered clinically eligible for both procedures. Participants in the randomized cohort are allocated 1:1 to either ceramic hip resurfacing or total hip arthroplasty and are kept blinded to treatment allocation where feasible through the 24-month primary follow-up.

The primary objective is to determine whether ceramic hip resurfacing results in greater objectively measured mean daily walking distance over the postoperative period from 3 to 24 months. Activity is assessed during standardized 7-day wearable monitoring periods at 3, 12, and 24 months. The primary estimand is the adjusted overall between-group difference across these postoperative time points. A parallel observational preference cohort may include otherwise eligible patients who decline randomization; this cohort is analyzed separately and does not contribute to the primary randomized inference.

Detaljeret beskrivelse

The trial is designed to test whether a contemporary ceramic-on-ceramic hip resurfacing strategy provides a clinically meaningful advantage over modern total hip arthroplasty in real-world physical activity. Randomization is stratified by study site and sex. All participants undergo baseline assessment including patient-reported outcomes, radiographs, clinical data, and 7-day wearable activity monitoring before surgery.

The randomized cohort includes 220 participants, 110 per treatment group. Follow-up is planned at 3 months, 12 months, 24 months, 5 years, and 10 years. Secondary outcomes include walking distance at 24 months, daily step count, patient-reported outcomes, radiographic outcomes, perioperative outcomes, complications, reoperations, revisions, implant survival, and health-economic outcomes. The study is academically led, and the observational preference cohort follows the same assessment schedule but is analyzed separately.

Beskrivelse

Inclusion Criteria:

  • Adults aged 18 years or older.
  • Symptomatic hip osteoarthritis for which primary hip arthroplasty is indicated according to routine clinical practice.
  • Considered suitable for both ceramic hip resurfacing arthroplasty and uncemented total hip arthroplasty by the treating surgeon.
  • Ability and willingness to comply with study procedures, including patient-reported outcome measures, radiographs, registry linkage, and repeated wearable monitoring.
  • Provision of written informed consent.

Exclusion Criteria:

  • Anatomical or pathological conditions that clearly preclude hip resurfacing arthroplasty or total hip arthroplasty, including severe deformity requiring non-standard implants or techniques.
  • Insufficient femoral head or acetabular bone quality, including large or multiple cysts, advanced femoral head necrosis, severe osteopenia, or osteoporosis where this would contraindicate hip resurfacing arthroplasty.
  • Body mass index greater than 40 kg/m^2.
  • Requirement for specialized implants outside routine study procedures.
  • Medical comorbidity rendering the patient unfit for surgery.
  • Cognitive impairment, severe psychiatric disease, alcohol or substance abuse, language barrier, or other reason judged to prevent informed consent or compliance with follow-up.
  • Inability to complete patient-reported outcome measures or to participate in wearable monitoring.

Eksperimentel: Ceramic Hip Resurfacing Arthroplasty

Participants undergo cementless ceramic-on-ceramic hip resurfacing arthroplasty using the selected study system according to manufacturer instructions, surgeon training requirements, and local surgical routines.

Cementless ceramic-on-ceramic hip resurfacing arthroplasty. The currently planned study implant is H1, or a subsequent equivalent generation if applicable. Procedures are performed by surgeons with documented arthroplasty experience and system-specific training.

  • H1 ceramic hip resurfacing
Aktiv komparator: Total Hip Arthroplasty

Participants undergo contemporary standard primary total hip arthroplasty using established implants and bearing combinations according to local routine and individual clinical assessment. Cementless fixation is expected in most cases where clinically appropriate.

Contemporary standard primary total hip arthroplasty using established implants and bearing combinations according to local routine and individual clinical assessment. Implant choice remains clinically appropriate for the individual participant.
