title: Comparison between results of high tibial osteotomy above and below tibial tubercle in relation to future total knee arthroplasty.
abstract: This prospective study included 50 patients with medial compartment osteoarthritis and varus knees. Twenty-five patients had high tibial closed wedge osteotomy above the tibial tubercle (TT) (group I), and the other 25 had the osteotomy just below it (group II). The two groups were matched. The osteotomies in both groups were fixed with plates and screws. All patients were followed up radiographically and clinically for more than 12 months. Clinical and radiographic results of both groups are comparable. Regarding factors that will affect future knee arthroplasty (TKA), osteotomies below TT are more advantageous. That is because soft tissues and bony changes of the knees in group II are minimal, and the issue of slower union rates can be diminished by using rigid plate fixation.
