The individualised design of the Episealer Talus implant and Epiguide are based on MR and/or CT imaging. By data processing, a virtual 3D model of the damaged talus surface is created and the lesion is defined. Subsequently, the Episealer and instruments are designed to remove the damaged tissue as well as to restore the area with a perfectly fitting implant. Using the Epiguide during surgery increases the precision of the surgical procedure for optimal positioning of the implant.

The Episealer is made of cobalt-chrome alloy. The part of the Episealer that is countersunk in the bone and cartilage is covered with a titanium undercoating and a hydroxyapatite outer coating, ensuring a quick and lasting fixation to the bone.

Episealer Talus can be used on both the medial and lateral side of the talar dome.



The Episealer Talus is an individualised resurfacing implant intended for use on either the medial or lateral talus. It aims to treat patients suffering from pain and reduced mobility due to focal osteochondral lesions in the talus. The Episealer technology restores the damaged joint surface in order to alleviate pain and quickly enables patients to recover joint mobility.

The Episealer Talus is available in a diameter of 15 mm.



The Episealer implant comes with an individualised drill guide, Epiguide, and a set of associated tools needed to ensure the best possible outcome.


The guide is designed to attach perfectly onto the talus’ surface around the lesion. This provides a stable platform to support you during the drilling process. The detailed preparation of the lesion site enables a simple and precise insertion of the implant at an exact angle and depth relative to the patient’s joint anatomy. This makes it possible to safe-guard against any part of the implant protruding, a situation which may jeopardise the final result. The individualised Epiguide’s design is based on the patient’s MR and/or CT images.




The Episealer toolkit consists of 7 pieces that will guide you through the Episealer procedure. All tools are made to fit the implantation of the Episealer and are single-use only. The whole kit is delivered together with the Episealer prior to the surgery, removing the need for any stock in your hospital.

The unique combination of the Epiguide and the associated Epidrill, Drilling socket and Adjustment socket allows for 200 µm precision depth adjustment, resulting in full control over the depth of the bone bed during the procedure.
