Clinical Trial 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.

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, and 2 years. Screening for adverse events and revision surgeries will occur throughout the study.

Target enrollment is 140 patients at up to 25 clinical sites. Subjects will complete the study at 2 years or will be withdrawn if the patient undergoes revision surgery of the Subchondroplasty site.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from baseline Foot Function Index-Revised (FFI-R) short form score at 12 Months	Change from baseline score, range 0-100, for patient reported pain, stiffness, difficulty, activity limitation and social issues at 12 months.	12 months
Secondary	Incidence and severity of device and/or procedure related adverse events and re-visions/re-operations	Summary and description of procedure and device related adverse events and surgical re-operations and relatedness to the bone substitute material and procedure	5 years
Secondary	Change in numeric pain score from baseline at 12 Months	Change in numeric pain score using a 0-10 scale from baseline at 12 months.	12 months
Secondary	Change in EuroQol-5 Dimensions (EQ-5D) from baseline at 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.	12 months
