The restor3d patient specific Total Talus Replacement System is an alternative treatment option to fusion or amputation designed to replace a native talus bone that has been affected by a disease state or injury. The system consists of a 3D printed Cobalt Chromium alloy implant and single-use disposable instrumentation including size trials and impactors to assist in surgical placement of the implant. The data driven design of the implant enables the patient to maintain ankle range of motion, reduce pain and improve physical function.
The restor3d Total Talus Replacement implant is indicated for:
The implant is patient specific and is designed from computed tomography (CT) scan. The anatomical landmarks necessary for the design and creation of the restor3d total talus replacement implant must be present and identifiable on CT scan. In addition to reading the information provided in this guide, please talk with your doctor. Your doctor will help you to understand the benefits and risks associated with the procedure and determine if you are a candidate for a Total Talus Replacement implant.

Recovery
The restor3d Total Talus Replacement implant not only prevented below the knee amputation, but it also improved the quality of life for many patients through reduced pain, maintained ROM and improved physical functioning.
These positive impacts afford patients the ability to return to work, maintain a healthy lifestyle through physical activity, and engage with friends and family.
Patients reported an improvement in perceived pain from baseline to last follow-up on both Pain NRS and PROMIS-Pain Interference measurement tools.

PROMIS Pain Interference - mean baseline and last follow-up scores by duration of follow-up.
Patients demonstrated improved physical function as more postoperative time elapsed. Importantly, patients who had more than 1 year of follow-up reported a 6-point improvement in PROMIS-Physical Function T-scores, nearly reaching normal limits of the scale.

By the 1-year postoperative time point, both plantarflexion and dorsiflexion returned to baseline.
