Dear Sir:

Thank you for your questions and comments regarding my recent article on hydroxyapatite opening wedge high tibial osteotomy.

As shown in my paper, we had no problems obtaining bone union or maintaining range of motion. Previously we used external fixation but because of complications (infections and peroneal palsy etc.) the incidence of which may be 6 times more than methods using internal fixation, we abandoned external fixation.

I also believe that with some practice, the method of determining the height of wedges is not complicated.

Thank you.

SIR, Your approach of using medial opening wedge osteotomy which requires wedges of hydroxyapatite for correcting the deformity seems unfavourable because the chance of non union is increased by the amount of periosteal stripping done for applying plates and closure of wound may be difficult with this approach particular approach.

It seems technically difficult, especially for the less experienced surgeon We use the Hemicallotasis approach which for us is very useful and needs no calculation of the angle. Mobilization of the knee becomes very easy.
