Abstract
Background
Correction of deformities about knee joint may prevent or delay the onset of osteoarthritis or mitigate its effects. Accurate correction of such deformities without production of secondary deformities depends on precise localization and quantification of the deformities.
Methods
We corrected deformities around the knee using acute correction with focal dome osteotomy in 21 segments (15 patients). Five segments underwent limb lengthening postoperatively.
Results
The mean correction angle was 16.0°. We were able to correct all segments. In the five lengthening cases, the mean external fixation index (EFI) was 70.9 days/cm, which is much higher than the generally reported EFI. There were eight complications, all but one of which occurred in lengthening cases.
Conclusions
We believe that acute correction with focal dome osteotomy is very useful for cases of alignment correction, but is not indicated for cases of alignment correction with lengthening, due to a high risk of complications related to poor callus formation.
