The likelihood of developing bumpy or uneven skin after liposuction can depend on various factors, including the technique used, the skill of the surgeon, and individual healing characteristics.

Liposuction techniques have evolved over time, and newer methods such as tumescent liposuction and ultrasound-assisted liposuction (UAL) aim to minimize the risk of irregularities or contour deformities. However, it's important to understand that there is still a potential for unevenness, especially if large volumes of fat are removed or if the donor site has pre-existing irregularities.

The specific risks associated with liposuction of the front and rear of the thighs (saddle bags and banana rolls) can include contour irregularities, lumpiness, asymmetry, or waviness of the skin. Additionally, if too much fat is removed from these areas, it may result in an unnatural or disproportionate appearance.

To minimize the risk of complications and achieve the best results, it's crucial to consult with a board-certified plastic surgeon who has extensive experience in performing liposuction and fat transfer procedures.

I hope this helps,
best of luck !
