Brief Summary:
Post Market clinical outcomes study to collect data on the short - and long-term outcomes for subjects who are undergoing or who have undergone the Subchondroplasty Procedure in the foot and/or ankle in a standard clinical setting. Outcomes to be assessed include pain medication usage, pain, function, activity levels and patient satisfaction.

Condition or disease Intervention/treatment
Insufficiency Fractures Stress Fracture Stress Fracture, Ankle, Foot and Toes Device: Treatment of insufficiency fractures

Detailed Description:

This is a post-market, multi-center, patient outcomes centered study to evaluate the on-label use of AccuFill during the Subchondroplasty procedure (SCP). Enrolled subjects will sign an informed consent form, satisfy the inclusion/exclusion criteria and have at least one bone marrow lesion, such as a cyst or stress fracture confirmed by diagnostic imaging in the foot and/or ankle joint. Demographics, medical history and medications will recorded at the time of enrollment. Surgical details including the SCP procedure, concomitant surgical procedures and intraoperative safety events will be recorded. Subjects will complete validated patient reported outcomes measures pre-operatively including the Foot Function Index (FFI) revised short form, the EQ-5D™ and numeric pain score. These measures plus a subject satisfaction survey will also be administered post-operatively at 6 weeks, 3 months, 6 months, 1 year, 2 years. At 3 years, 4 years, and 5 years, numeric pain scores and a patient satisfaction survey will be collected. Screening for adverse events and revision surgeries will occur throughout the study.

Target enrollment is 250 patients at up to 25 clinical sites. Subjects will complete the study at 5 years or will be withdrawn if the patient undergoes revision surgery of the Subchondroplasty site.

Intervention Details:
  • Device: Treatment of insufficiency fractures
    Filling of micro fractures or insufficiency fractures with a bone substitute material

Primary Outcome Measures :
  1. Change from baseline Foot Function Index-Revised (FFI-R) short form score at 12 Months [ Time Frame: 12 months ]
    Change from baseline score, range 0-100, for patient reported pain, stiffness, difficulty, activity limitation and social issues at 12 months.

Secondary Outcome Measures :
  1. Incidence and severity of device and/or procedure related adverse events and re-visions/re-operations [ Time Frame: 5 years ]
    Summary and description of procedure and device related adverse events and surgical re-operations and relatedness to the bone substitute material and procedure

  2. Change in numeric pain score from baseline at 12 Months [ Time Frame: 12 months ]
    Change in numeric pain score using a 0-10 scale from baseline at 12 months.

  3. Change in EuroQol-5 Dimensions (EQ-5D) from baseline at 12 months [ Time Frame: 12 months ]
    Change in patient quality of life from baseline at 12 months. A scoring function is created using a population preference weighted health index. The change from the baseline score will be measured at 12 months.
