Background
Puddu had presented a special osteotomy plate in early 1990s, which had a spacer for
internal support of the medial opening wedge osteotomy of variable heights (from 5mm to
17.5mm). In the current study, we present our results of opening wedge HTO using Puddu
plate.
Patients and methods
Between June 2012 and august 2015, 30 knees (in 29 patients) were prospectively enrolled
in current study. Twenty patients were male and 9 were females. The average age
of the patients were 21.5 years (range, 15-30). Two adolescent patients had open proximal
tibial growth plate. The average follow up period was 30 m0nth (range, 24 to40). All
patients had opening wedge high tibial osteotomy using Puddu plate.
Results
Union was achieved in all patients with no need for bone grafts except in only one patient.
The average time to union was 16 weeks (range, 12 to 24). The mean pre-operative mechanical
tibiofemoral (MTF) angle was11.27 degrees varus (range, 5 to 16), while the
mean post-operative MTF angle was 4.53 degrees’ valgus (range, 2 to 7). Overcorrection
(MTF angle >6) occurred in 4 cases, while no under correction (MTF angle |
