Postural assessment of patients with non-conventional knee endoprosthesis.

Objective: To investigate the correlation between the sagittal and frontal alignment and possible postural asymmetries found in patients submitted to total knee stent placement for osteosarcoma.

Methods: TWENTY TWO INDIVIDUALS WERE DIVIDED INTO TWO GROUPS ACCORDING TO TUMOR LOCATION: femur group (13 patients) and tibia group (nine patients), who were evaluated through postural analysis software (SAPO).

Results: No statistically significant difference was found between groups, supporting previous result showing that both groups present the same postural asymmetries.

Conclusion: We conclude that both groups have the same postural imbalances, especially the knee of the affected limb that presents hyperextension and center of gravity shifted anteriorly and laterally to the non-affected limb, indicating changes in weight bearing and influencing the gait pattern and balance.
