title: Total knee arthroplasty with long stem for treatment of nonunion after high tibial osteotomy.
abstract: Nonunion is an uncommon complication of high tibial osteotomy (HTO), and thus literature regarding treatment of it is very limited. The usual treatment for nonunion after HTO is repeat fixation of the osteotomy site. When union is not achieved, hinge or constrained total knee arthroplasty (TKA) is used. We describe a patient for whom nonunion after HTO was successfully treated using long-stem TKA with bone graft to have the nonunion site unite simultaneously.
