چکیده مقاله:

BackhroundsBackground: Total knee arthroplasty in patients with severe varus deformity is demanding.In most of these patients, extensive medial release is needed and this may yield to instability.Medial epicondylar osteotomy may be a better option instead of complete medial collateralreleaseMethodsMaterial and methods: 14 patients had undergone medial epicondylar osteotomy formedio-lateral imbalance correction in total knee replacement. In seven cases, extensivemedial release had been previously done for the contralateral side. Patients were evaluatedone year after operation for clinical results. Physical examination was done and clinicalquestionairs were recorded for patients. Radiography was also done and union of theosteotomized fragment was evaluated.ResultsResults: The mean varus angle before surgery was 4.7± 23.6 degrees and corrected to the2.96± 12.6 degrees after operation. The mean varus of contralateral side was 21.61.7±degree and corrected to 7.5 degrees after operation. Medial joint line opening in valgusstress test was 0.42±2.7 mm in osteotomized side and 0.9±3.5 mm in contralateral side.Mean ROM for osteotomized side was 4.34± 97.86 and for contralateral side was 100.71degrees ± 2.76 (p=0.69).There was one case with non union. In non of knees with medialrelease or osteotomy patients had complain of medial instabilty. Three of patients weresatisfied more from osteotomy than release. VAS for pain was lesser in osteotomized knee.ConclusionsConclusion: medial epicondylar osteotomy is a safe technique and has the same results ofwell controlled extensive release.
