Abstract
There are several reports that open wedge high tibial osteotomy with plate is associated with change in the posterior tibial slope and patellar height. We radiologically evaluated 65 knees with open wedge osteotomy using hemicallotasis between 2006 and 2008. Clinically JOA score significantly improved from average 63.0 points to 88.5 points. In X-ray examination, the average preoperative femoro-tibial angle 181.5° was corrected to 168°. However, there were no significant changes in the posterior tibial slope and patellar height after surgery. Their results suggest that open wedge osteotomy using hemicallotasis has several merits in knee function rather than osteotomy with plate.
