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

September 21, 2026 updated by: 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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Procedure: Ceramic-on-Ceramic Hip Resurfacing Arthroplasty

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean Daily Walking Distance Over the Postoperative Period From 3 to 24 Months
Time Frame: 3, 12, and 24 months after surgery

Mean daily walking distance is assessed during standardized 7-day wearable monitoring periods at each postoperative time point.
