[High tibial dome osteotomy complications in genu varum patients].
OBJECTIVE
To identify if pre-surgical risk factors or the surgical technique were associated with the complications of the osteotomy in genu varus patients.


METHODS
A case-control study was conducted in patients that underwent Maquet proximal tibial osteotomy for treatment of genu varus between January and December 2003. The risk factors were the following: age 50 or more years old, comorbidity such as type 2 diabetes, hypertension, rheumatoid arthritis, overweight and obesity (BMI > or = 25 and > or = 30), duration of ischemia longer than 60 min and local pain. Cases were those who developed one or more complications. Descriptive and inferential statistical analyses were performed.


RESULTS
One hundred and thirty-four patients were included, among which 53% had complications. None of the risk factors were statistically significant (p > 0.05).


CONCLUSIONS
None of pre-surgical risk factors were associated with the complications of osteotomy; therefore, these could be attributable to the surgical technique. It is necessary to outweigh the temporary benefits of the tibial osteotomy versus the increase in the risk of complications when performing total knee arthroplasty.
