THE ROLE OF THE HIGH TIBIAL OSTEOTOMY IN UNICOMPARTMENTAL GONARTHROSIS.

The aim of this study is to determine clinical and radiographs results in the treatment of unicompartmental gonarthrosis after medial tibial osteotomy with bone graft from the iliac crest associated with arthroscopy and knee débridement. Method: The study was performed in 19 patients treated with exploratory arthroscopy and articular débridement followed by medial opening tibial osteotomy in the proximal third with a bone graft stabilized with plate and screws or cramps. The pre and postoperative factors analyzed within this study are: age, KSS score, Alhback score, preoperative and postoperative knee varus and valgus alignment, ligament stability degree, immediate and late adverse events and patient satisfaction with the procedure. Conclusions: After investigations, we consider that high opening tibial osteotomy with bone graft from the iliac crest associated with débridement arthroscopy is an alternative in the treatment of the unicompartmental gonarthrosis, favoured by the precision of the arthroscopic diagnosis [ABSTRACT FROM AUTHOR]
