A Prospective, Post-marketing Registry on the Use of ChondroMimetic for the Repair of Osteochondral Defects

Study Overview
=================
Brief Summary
-----------------
The objective of this post-marketing study is to confirm the clinical efficacy and safety outcome of treatment with ChondroMimetic in a patient population within the proposed indication (osteochondral cartilage defects), over a 36 months post-implantation follow-up period. The primary objective is to collect post-marketing safety data in a real life setting by means of (S)ADR reporting. The secondary objectives are: Clinical outcome as assessed by patient reported EuroQoL-5D Structural repair as assessed by MRI The number of treatment failures and the time to treatment failure The ease of use of ChondroMimetic as reported by the surgeon

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Osteochondral lesions<br>Patients with osteochondral lesions in the knee, the ankle, or other joint | Device: Chondromimetic<br>* The Chondromimetic implant is intended to serve as a scaffold for cellular and tissue ingrowth in osteochrondral defect repair such as bone and/or cartilage. The plug consists of a chondral layer with collagen and GAG and an osseus layer with collagen, GAG, and calcium phosphate.<br>* Other names: CM;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety data | Safety data as measured by adverse device reactions | on ongoing basis up to 3 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| EuroQoL-5D | The EQ-5D is a descriptive system of health-related quality of life states consisting of five dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression) each of which can take one of three responses. The responses record three levels of severity (no problems/some or moderate problems/extreme problems) within a particular EQ-5D dimension | baseline, 6, 12, 24, 36 months | 
| MRI | Structural repair will be assessed by MRI. The available MRIs will be collected and scored by an independent radiologist, using the published MOCART score , and one additional item, level of the subchondral bone plate. | baseline, 12, 24, 36 months | 
| Failure rate | Treatment failure is defined as a re-intervention on the index lesion, prompted by persistence or recurrence of symptoms related to the index knee. The date of failure is the actual date of re-intervention. | 3 years |
