Outcome Measures

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.

Interventions

Injection of the commercially available flowable calcium phosphate (CaP) synthetic bone-void filler, AccuFill®, into subchondral bone defects in the hip (Subchondroplasty (SCP) Procedure).

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
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.

You may qualify if:

  • Candidates must meet ALL of the following:
  • Surgeon considers the patient appropriate for the SCP Procedure of the hip.
  • Subchondral bone defect(s) in the femoral head, femoral neck and/or acetabulum has been confirmed via radiographic finding on MRI or x-ray.
  • Subject provides voluntary signature on the IRB approved Informed Consent Form.
  • Subject is at least 18 years of age.
  • 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.

  • Candidates will be excluded if they meet ANY of the following:
  • Subject has collapse of subchondral bone.
  • Subject is pregnant at the time of surgery.
  • Subject is incarcerated.
  • Subject is involved in active litigation related to the condition being treated.
