The Management of Complex Knee Deformity Using Ortho-SUV: A Case Study.

Lower limb deformities are debilitating and affect the function of the lower limb and the social life of the patient. The deformities around the knee joint might be a combination of multiple deformities in various planes including coronal, sagittal, or rotational and may be present in both the femur and the tibia. We present a case of a 19-year-old female with complex deformity around the left knee joint involving both the femur and the tibia with shortening. The deformity was thoroughly planned and managed with both the Ortho-SUV and the Ilizarov technique. Complications such as neurological injury and nonunion were faced, but the neurology was improved spontaneously, and the autologous bone graft was done. The end result was excellent with no residual neurodeficit and no limb length discrepancy. Deformities such as these have to be addressed with meticulous planning and strategic surgical management. Complications such as nonunion, infection, neurological injury, and noncompliance might be faced in the course of the treatment. Though the Ilizarov apparatus is the most commonly used to address deformities and limb lengthening, the newer six-axis devices such as the Ortho-SUV can greatly aid in deformity correction.
