Summary of pre-clinical findings related to COPLA®
- The COPLA® structure enables immediate mobility after surgery
- It has demonstrated the potential for good cartilage and cartilage-bone lesion filling in a short time
- The COPLA® repaired tissue quantity and quality are enhanced parallel to increasing weight-bearing properties of the repaired site
- The COPLA® structure serves as an exceptional substrate for various joint-relevant cell types facilitating targeted tissue growth
- The COPLA® structure’s properties combined with the biological milieu in the joint create a unique combination of optimal load transfer and effective fluid transduction in the damaged area
In short, the COPLA® structure empowers cartilage regeneration and joint preservation.
