Clinical Trial Summary

The aim of this RCT is to show, that in a patient group receiving COLLOSS E combined with TomoFix for medical open wedge high tibial osteotomy, the onset of bone healing is earlier in time, compared to patients receiving TomoFix without COLLOSS E.


Description:

The healing effect should be demonstrated by using MRI pictures during the entire FU's in order to demonstrate the differences if COLLOSS E is applied or not.
