High Tibial Osteotomy Open Wedge Osteotomy versus Close Wedge Osteotomy in Relation to Patella Baja as Asequale to this Osteotomy

Abstract

Study design :
Our study is aretrospective study to asses the level of the patella after valgus high tibial osteotomy in 2 groups of patients group A perform to them open wedge valgus high tibial osteotomy and groupB perform to them close wedge valgus high tibial osteotomy.
material and method :
Our study include 18 patients perform to them valgus high tibial osteotomy from January 2004 – October 2008 in multi center in Baghdad and alnajaf cities ,age between 40-60 years average 45 years 9 of them perform to them open wedge valgus high tibial osteotomy and 9 of them perform to them close wedge high tibial osteotomy.
Result:
The mechanical hip-knee-ankle angle improved from average 168 degree to average184 degree . patella baja observed in both groups of patients but it is more sever in group A than in group B i.e it is more sever in patients with open wedge valgus high tibial osteotomy than in close wedge valgus high tibial osteotomy .
conclusion :
Patella baja is common after valgus high tibial osteotomy , it is more sever in patient with open wedge valgus high tibial osteotomy than close wedge valgus high tibial osteotomy ,according to the blackburne – peel index and insall salvati index , this effect the function of the joint according to the severity of the patella baja in both groups of patients .
