Innovation in only one step.

Implantation technique

The implantation of chondrotissue® can be done in only one step: there is no need to take a cartilage biopsy from the patient and no need to wait weeks for cell culture.

1 Debridement

The cartilage defect must be debrided until the subchondral bone is exposed. Damaged cartilage must be removed and the defect must be prepared.

2 Measurement

The debrided defect should be measured with an arthroscopic measuring gauge or with a simple surgical ruler if surgery is performed by arthrotomy.

3 Bone marrow stimulation

The defect should be perforated with an awl or a drill with spacing around 3-5 mm.

4 Reconstitution of chondrotissue®

In order to restore the elastic properties of condrotissue®, it is recommended to put it directly in the sterile container supplied with 2-3 ml of one of following sterile rehydrating fluids for approx. 2 minutes.

Following alternatives shall be used to reconstitute chondrotissue®:

  • human autologous platelet-rich plasma (PRP)
  • physiological saline for infusion
  • autologous human serum taken before implantation and prepared from approx. 9ml of blood. The blood can be centrifuged for 10 minutes or left to stand at room temperature for about 30 minutes until the blood clot has settled.
    IMPORTANT: please use serum monovettes, not EDTA monovettes.

If too little PRP or human serum is available, physiological saline fo infusion can be supple-mented to reconstitute the elasticity of chondrotissue®.

5 Preparation of chondrotissue®

The moistened chondrotissue® can then be cut exactly to size to fit the defect.

6-7 Fixing chondrotissue®


chondrotissue® can be fixed in the defect using common orthopaedic fixation methods e.g.:

  • bioresorbable nails
  • transosseous ancher knot fixation
  • cartilage suture
  • fibrin glue: Please apply the glue to the edges of the chondrotissue® – previously placed in the defect – and distribute it evenly.
