Genu varum is among the most common orthopaedic problems which mostly leads in
osteoarthritis. High tibial osteotomy (HTO) is a way for prevention and treating knee
osteoarthritis. Various models of HTO have been proposed and in parallel, HTOassociated
problems. The purpose of this study was to investigate the clinical results
of a new innovative method of HTO named MIS reversed V-shaped high tibial
corticotomy in a follow-up period of 3-13 years. Methods: Between 1996 and 2006,
293 patients with medial compartment osteoarthritis and or genu varum were
operated on, using our new method. Patients were examined and interviewed before
and 6 months after surgery and clinical examination recordings and post-operative
complications were registered. Also at the final follow up limb alignment and patients’
satisfaction was reassessed. Results: The early post operative complications were
varus recurrence, knee pain and no sign of tibial non-union or infection were
observed. In final follow up the only observed complications were few cases of mild
genu recurvatum, knee pain and loss of correction. There was no relationship
between the underlying pathologies and loss of correction in this study and no
significant difference between age groups regarding loss of correction was observed.
Conclusion: This method can be a feasible alternative for correction of genu varum
because of a small incision, being soft tissue friendly, a corticotomy instead of
osteotomy, no internal fixation devices, shorter duration and an acceptable rate of
complications and recurrences and finally higher patient satisfaction.
