Hello, thank you for your inquiry about the timeframe for observing results following knee liposuction. It's important to recognize that individual experiences vary, and surgical techniques among plastic surgeons differ. Generally speaking, the final outcomes of any liposuction procedure, including knee liposuction, become apparent within 6 to 8 weeks. This timeline accounts for the resolution of swelling or edema, which is a common post-surgical occurrence, regardless of the liposuction technique employed. Techniques such as VASER, LASER, power-assisted liposuction, jet liposuction, or traditional liposuction all typically see swelling subside by the 6 to 8-week mark. Given that the knee area is prone to fluid accumulation due to its lower position in the body, wearing a compression garment specifically designed for the knee region is advisable. It is also crucial to maintain regular follow-up appointments with your plastic surgeon to monitor for any potential complications, such as seromas (serous fluid collections) or hematomas (blood collections). Should you develop a seroma or hematoma, needle drainage may be necessary to address these issues. I appreciate your question about how long it takes to see results after knee liposuction and hope this response provides clarity. Sincerely, J. Timothy Katzen, MD, FASMBS, FICS Plastic and Aesthetic Surgeon
