Study summary

Post-market clinical outcomes study to collect data on the short- and long-term outcomes for subjects who are undergoing or have undergone the Subchondroplasty® (SCP®) Procedure in the hip in a standard clinical setting. Outcomes to be assessed include medication usage, pain, function, activity levels and patient satisfaction.

Read the detailed description

This study is designed as a post-market, single arm, non-randomized multi-center investigation.

Male and female subjects, at least 18 years of age, with at least one subchondral bone defect in the form of a cyst and/or bone marrow lesion (BML), insufficiency fracture or bone defect associated with early stage avascular osteonecrosis (AVN) in the femoral head, femoral neck and/or acetabulum who are suitable candidates for use of AccuFill during the Subchondroplasty Procedure are eligible for enrollment in this study.

A maximum of 15 study sites, in the United States of America, will enroll a target of 50 subjects.

Each Investigator must obtain IRB approval, or favorable opinion by an EC, prior to consent of the first subject; no study-related procedures can occur without the approval and oversight of a registered IRB or EC. If the study site does not have an IRB of record, a central IRB may be utilized upon approval by Zimmer Biomet.

Demographics, medical history, hip history and use of pain medication and therapy will be recorded at the time of subject consent. Additionally, patient reported outcomes measures will be obtained pre-operatively. Operative details including the SCP Procedure, concomitant surgical procedures and intraoperative safety events will be recorded at the time of surgery. Prospective subjects will be considered enrolled in this study once their Subchondroplasty Procedure has been performed.

Subjects will complete only the Numeric Pain Scale at 2 weeks post-operatively. Thereafter, subjects will complete self-reported outcomes measures post-operatively at 6 weeks, 12 weeks, 6 months, 1 year and 2 years. These measures include information on pain medication and therapy, pain levels, function, activity and subject satisfaction. Screening for adverse events and conversion will occur throughout the study.

Subjects will complete the study at 2 years or will be withdrawn if they undergo conversion of the Subchondroplasty site. For the purposes of this protocol, a conversion will be defined as total hip arthroplasty or any procedure involving removal of the AccuFill material on the index hip.

Study population

Approximately 50 subjects, each with at least one subchondral bone defect in the form of a cyst and/or bone marrow lesion (BML), insufficiency fracture or bone defect associated with early stage avascular osteonecrosis (AVN) in the femoral head, femoral neck and/or acetabulum who are suitable candidates for use of AccuFill during the Subchondroplasty Procedure are eligible for enrollment in this study.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Candidates must meet ALL of the following:

    1. Surgeon considers the patient appropriate for the SCP Procedure of the hip.
    2. Subchondral bone defect(s) in the femoral head, femoral neck and/or acetabulum has been confirmed via radiographic finding on MRI or x-ray.
    3. Subject provides voluntary signature on the IRB approved Form.
    4. Subject is at least 18 years of age.
    5. Subject must be physically and mentally willing and able, in the Investigator's opinion at the time of enrollment, to be compliant with the protocol and complete outcome forms via email, telephone, in-person or by regular mail.

Exclusion criteria

Exclusion Criteria:

  • Candidates will be excluded if they meet ANY of the following:

    1. Subject has collapse of subchondral bone.
    2. Subject is pregnant at the time of surgery.
    3. Subject is incarcerated.
    4. Subject is involved in active litigation related to the condition being treated.
    5. Subject is not comfortable with speaking, reading, and understanding questions and providing responses in an available language for the PROs in the protocol.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Overall Group Mean Improvement From Baseline of the Modified Harris Hip Score (mHHS) at 2 Years

    Change in Modified Harris Hip Score using a 0-100 overall score, from baseline at 2-years. Subscales of pain, function, and activity levels are combined to generate the overall score. Pain is scored out of 44 possible points, function is scored out of 33 possible points and subject activities are scored out of 14 possible points. The maximum score of 91 is multiplied by 1.1 to give a total score out of 100; a higher score represents better patient reported pain, function and activity levels.

    Time frame: 2 Years

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 21, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
