Postural assessment of patients with non-conventional knee endoprosthesis

Abstract

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. Level of Evidence II, Prospective Comparative Study.

Posture and quality of life in children with hemiparesis

“…The right knee joint showed a positive angle, which means flexion deformity (crouch). The knee's bending angles are (positive values), and the extension angles are (negative values) (20). Miller and Clark (21) cited that the most common problems encountered in the lower limbs of hemiparetic children are evident in the region of the knees, ankles, and feet, where the motor control may be unsatisfactory.…”
