The patient’s detailed MRI (or also CT can be used for the ankle) is used to create a detailed virtual model of the femoral knee/talus forming the base of Episurf’s so called Damage Marking Report (DMR). The report enables 3D visualisation of:

  • Cartilage damage*
  • Subchondral bone damage such as bone cysts and edema*
  • Signs after previous surgeries
  • (Osteo)arthritic signs
  • Other pathologies

* cartilage damage and edema are not visualised when the DMR is based on CT

This 3D visualisation will enable the clinical team to explore a patient’s individual level of damage and assess their suitability for an Episealer implant. If it is assessed that an Episealer is a suitable option for the patient, an order shall be confirmed for the implant and associated tools for treatment of the chondral or osteochondral defect. The suggested Episealer pre-planning visualisation ‘Final Design’ will be provided by Episurf, showing the exact planned position of the Epiguide and Episealer. This positioning can be fine-tuned through communication between Episurf and the responsible surgeon if so needed.



All Episurf Damage Marking Reports are accompanied by a virtual, interactive 3D model. This model enables the surgeon to navigate through the knee/talus and add/remove structures and devices in order to get a better visualisation of the lesion, implant and cartilage.
