Opening-wedge osteotomy can offer precise correction before TKA

ORLANDO, Fla. — Medial opening-wedge osteotomy has shown the ability to easily obtain precise correction, according to a speaker here.
“Looking at the impact of a variety of patient factors and surgical factors, both body weight and the correction you obtain at the time of surgery do influence the survivorship to total knee replacement,” Mark W. Pagano, MD, said at the Current Concepts in Joint Replacement Winter Meeting. “If you get the ideal correction in a relatively normal-weight person, the survivorship at 5 years and 10 years is satisfactory.”
Other advantages of the opening-wedge technique include the ability to correct deformities in the sagittal plane and in the coronal plane, the need to make only one bone cut and the avoidance of the tibiofibular joint.
Disadvantages of the opening-wedge technique include the need for bone graft to fill the created defect, a potentially higher rate of nonunion or delayed union and a longer period of restricted weight-bearing after the procedure.
“Thus, [the opening-wedge technique] is better for the mild to moderate corrections that are part of contemporary upper tibial osteotomy,” Pagano said.
The opening-wedge technique offers precise correction at the cost of a longer time to union, he said. – by Nhu Te
