The restor3d Outcomes Registry

July 6, 2026 updated by: Restor3D

The restor3d Outcomes Registry: Tracking Patient Recovery After Joint Replacement

The restor3d Outcomes Registry is a prospective, longitudinal, decentralized study designed to capture patient-reported outcomes (PROs) from adults who have received an FDA-cleared or approved restor3d patient-specific orthopedic implant. Using a master protocol framework, the study enrolls patients across multiple joint cohorts (knee, hip, foot & ankle, shoulder) under a single protocol, with joint-specific details governed by individual appendices. Participants self-enroll and complete electronic PRO surveys (ePROs) before surgery and at 6 weeks, 3 months, 6 months, and annually through 5 years post-operatively, all remotely, with no required in-person visits. The study aims to quantify changes in pain, function, quality of life, and satisfaction over time, and to establish real-world outcome benchmarks for patient-specific orthopedic implants.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Patient-Reported Implant Survivorship (all cohorts)
Time Frame: Pre-operative baseline through 5 years post-operatively (assessed at 6 weeks, 3 months, 6 months, 1, 2, 3, 4, and 5 years)
Patient-reported implant survivorship as assessed through a sponsor-created post-market safety questionnaire, capturing implant-related adverse events including device malfunction, revision surgery, infection, wound complications, and life-threatening events.
Pre-operative baseline through 5 years post-operatively (assessed at 6 weeks, 3 months, 6 months, 1, 2, 3, 4, and 5 years)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Patient-Reported Outcomes Measurement Information System (PROMIS) Depression 6a Score (all cohorts)
Time Frame: Pre-operative baseline through 5 years post-operatively (assessed at 6 weeks, 3 months, 6 months, 1, 2, 3, 4, and 5 years)
Improvement in Patient-Reported Outcomes Measurement Information System (PROMIS) Depression 6a score evaluated by comparing postoperative scores to baseline. Raw scores range from 6 to 30 on a 5-point Likert scale. Higher raw scores indicate greater severity of depressive symptoms.
Pre-operative baseline through 5 years post-operatively (assessed at 6 weeks, 3 months, 6 months, 1, 2, 3, 4, and 5 years)
Hospital Stay (all cohorts)
Time Frame: 6 weeks post-operatively
Length of hospital stay (in nights) via non-validated patient-reported outcome measure.
6 weeks post-operatively
Change in Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS, Jr) Score (Knee cohort)
Time Frame: Pre-operative baseline through 5 years post-operatively (assessed at 6 weeks, 3 months, 6 months, 1, 2, 3, 4, and 5 years)
Improvement in Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS, Jr) evaluated by comparing postoperative scores to baseline. KOOS JR is a 7 item scale where items are originally rated on a 5-point Likert scale (0 to 4), creating a raw sum score (0-28), which is then converted into the 0-100 interval score. A higher score indicates better joint.
Pre-operative baseline through 5 years post-operatively (assessed at 6 weeks, 3 months, 6 months, 1, 2, 3, 4, and 5 years)
Change in Ankle Osteoarthritis Scale (AOS) Score (Foot & Ankle cohort)
Time Frame: Pre-operative baseline through 5 years post-operatively (assessed at 6 weeks, 3 months, 6 months, 1, 2, 3, 4, and 5 years)
Improvement in Ankle Osteoarthritis Scale (AOS) evaluated by comparing postoperative scores to baseline. The AOS consists of 18 items divided into two subscales (9-item Pain subscale and 9-item Disability subscale), typically using a 100-mm Visual Analog Scale (VAS) for each answer. Higher scores indicate a worse condition, meaning more pain and greater disability
Pre-operative baseline through 5 years post-operatively (assessed at 6 weeks, 3 months, 6 months, 1, 2, 3, 4, and 5 years)
Change in Hip Disability and Osteoarthritis Outcome Score, Joint Replacement (HOOS, JR) Score (Hip cohort)
Time Frame: Pre-operative baseline through 5 years post-operatively (assessed at 6 weeks, 3 months, 6 months, 1, 2, 3, 4, and 5 years)
Improvement in Hip Disability and Osteoarthritis Outcome Score, Joint Replacement (HOOS, JR) evaluated by comparing postoperative scores to baseline. The HOOS JR is a 6-item patient-reported survey used to evaluate hip health, with scores ranging from 0 to 100, which higher scores indicating better health.
Pre-operative baseline through 5 years post-operatively (assessed at 6 weeks, 3 months, 6 months, 1, 2, 3, 4, and 5 years)
Change in Single Assessment Numeric Evaluation (SANE) score (Shoulder cohort)
Time Frame: Pre-operative baseline through 5 years post-operatively (assessed at 6 weeks, 3 months, 6 months, 1, 2, 3, 4, and 5 years)
Improvement in Single Assessment Numeric Evaluation (SANE) score evaluated by comparing postoperative scores to baseline. The SANE score is a patient-reported outcome measure where patients rate their shoulder on a 0-100% scale (100% being normal).
Pre-operative baseline through 5 years post-operatively (assessed at 6 weeks, 3 months, 6 months, 1, 2, 3, 4, and 5 years)
Change in American Shoulder and Elbow Surgeons (ASES) score (Shoulder cohort)
Time Frame: Pre-operative baseline through 5 years post-operatively (assessed at 6 weeks, 3 months, 6 months, 1, 2, 3, 4, and 5 years)
Improvement in American Shoulder and Elbow Surgeons (ASES) score evaluated by comparing postoperative scores to baseline. The ASES score is a 100-point patient-reported outcome measure used to evaluate shoulder pain and function. It combines a 0-10 pain visual analog scale (weighted 50%) and 10 activities of daily living (ADL) questions (weighted 50%). Scores range from 0 (worst) to 100 (best).
Pre-operative baseline through 5 years post-operatively (assessed at 6 weeks, 3 months, 6 months, 1, 2, 3, 4, and 5 years)
