High tibial osteotomy with OssGro® wedges

A patient suffering from chronic knee pain and joint instability.


Diagnosis and treatment

The patient was diagnosed with a varus deformity and surgeons performed an open wedge High Tibial Osteotomy (HTO), inserting an OssGro® wedge into the medial side of the tibia, and securing it with a metal plate and screws.



After one year, the OssGro® wedge was fully integrated, and the metaphyseal triangular space was filled with newly regenerated bone. As seen in the X-ray, the spacing between the tibia and the femur indicates the presence of cartilage.
