Combination of Lipofilling With Liposuction in the Correction of Pseudo Genu Varus Deformity

The combined use of lipofilling and liposuction has not been reported for the correction of pseudo genu varus deformity.

The aim of this study was to evaluate the utility of combined liposuction and lipofilling for a bilateral correction of pseudo genu varus deformity based on a single-center experience over a 13-year period.

A total of 72 patients with pseudo genu varus deformity treated with combined liposuction and lipofilling were included. Data on postoperative complications, the need for additional rounds of lipofilling, and aesthetic outcomes over an average of 5 years (range, 1-9 years) were recorded.

Fat harvested from the upper medial portion of the knee was sufficient for lipofilling in 12 (16.7%) patients, and additional donor sites were used in 60 (83.3%) patients. A second round of lipofilling (average, 20 mL; range, 15-50 mL) was required in 17 (23.6%) patients within 6 months to 1 year after the operation. The need for additional lipofilling or liposuction was not noted for any other patients. None of the patients developed major complications such as fat necrosis, infections, contour deformities, or medial concavities during knee flexion.

The current findings strongly suggest that the combined use of liposuction and lipofilling for the correction of pseudo genu varus deformity is a feasible, effective, and safe alternative that seems to offer additional benefits compared with fat grafting alone, including a fast recovery, a low risk of complications, and an increased likelihood of a long-lasting correction of the calf contour.
