When skin forms folds above the knee, treatment depends on whether the main concern is fat, mild laxity, or excess skin that can only be removed surgically.
What is a knee lift?
It is surgery to remove excess skin from the lower thigh and tighten the tissue that hangs over the knee. It can be performed alone or combined with liposuction when localized fat is also present.
In the technique we use, the scar is curved and lies along the upper border of the knee. Surgery can improve folds and sagging, but does not erase every wrinkle or stop skin aging.
There must be enough excess for the improvement to justify a permanent scar.
Liposuction is added if there is localized fat; it does not replace skin excision.
It follows the upper border of the knee and matures over months.
Improves excess skin without promising wrinkle-free skin or complete symmetry.

Wrinkles, localized fat, or excess skin above the knee?
Not every knee that appears aged needs a lift. The examination should separately assess skin quality, fat thickness, the amount of tissue forming the fold, and how laxity continues toward the thigh.
Localized fat
It can give the inner or upper knee a rounded appearance. If the skin retains a good ability to adapt, we may consider liposuction without removing skin.
Laxity or thin skin
This causes fine wrinkles or a crepey appearance, but not always a fold that can be removed. When appropriate, nonsurgical treatments offer more modest changes than excision.
Excess skin
This forms one or more folds when standing and may become more noticeable when the leg is extended. This is the component that may genuinely justify a lift.
When might surgery make sense?
A lift is considered when excess skin is visible, stable, and substantial enough for excision to produce a proportionate improvement. Weight should be stable, and expectations must include the position and evolution of the scar.
| Main finding | What may be considered | What should not be promised |
|---|---|---|
| Fat with firm skin | Liposuction alone | Removing skin or fine wrinkles |
| Fat and excess skin | Liposuction and a lift during the same surgery | Scar-free correction |
| A skin fold above the knee | A lift alone | Completely smooth skin or immunity to aging |
| Fine wrinkles without removable excess | Selected skin care or nonsurgical treatments | The same change as skin removal |
This guide does not replace an examination. Skin quality, previous scars, smoking, circulation, weight, and combined surgery may change the indication.
How a knee lift is performed
Surgery is planned with the patient standing, because the position and amount of hanging skin change when sitting or bending the leg. The design must anticipate both the excision and the tension placed on the closure when the knee moves.
If localized fat is present, it may be treated first with liposuction. The planned excess skin is then removed and the wound closed in layers. When there is no significant fat component, a lift can be performed alone. This combination is also described in the literature on liposuction-assisted thigh lifts, although the specific indication at the knee must be determined by its anatomy.
Anesthesia, procedure time, outpatient care, or the need for observation depend on treatment extent and whether another surgery is combined. These are confirmed after examination and preoperative assessment.

Standing markings
The fold is outlined and we check how much tissue can be removed without placing excessive tension on the closure. - 02
Liposuction, if indicated
Treats excess fat; it is not automatically added for every patient. - 03
Skin excision
The excess lower-thigh skin hanging over the knee is removed. - 04
Closure and protection
The sutures are adapted to a mobile area and protected during the first stage of healing.
Where is the knee lift scar?
The scar forms a curve along the upper border of the knee. It should not be described as a tiny or invisible incision: its length depends on the amount and distribution of skin that needs removing.
Initially, it may look red, firm, or slightly raised. It usually gradually flattens and fades over months, although its final quality depends on tension, genetics, wound care, smoking, sun exposure, and each patient's healing.
The line is curved to follow the contour of this area.
It may become discreet, but cannot be guaranteed to be imperceptible.
Bending and straightening the knee influence care during the first few weeks.
What can change in knee lift before-and-after results?
The main change is reducing the skin fold resting over the knee and smoothing the transition to the lower thigh. If liposuction is combined, a fat deposit affecting the contour may also be reduced.
The result should not be judged during the first few days: swelling, bruising, and initial stiffness may conceal it. Absolute symmetry, the absence of fine wrinkles, or the texture of youthful skin cannot be promised either.
Can knees be rejuvenated without surgery?
Mild laxity or thin skin may improve modestly with some treatments, but excess forming a fold cannot be eliminated without excision. Reducing fat without anticipating how the skin will adapt can also make sagging more noticeable.
The knee-specific literature is limited. A randomized trial of 20 women treated with poly-L-lactic acid found improvement on physician assessment, but no significant difference in patient satisfaction, and called for larger, longer studies. Another study of 20 women treated with microfocused ultrasound and calcium hydroxylapatite reported qualitative improvements at 12 and 24 weeks, without significant changes in quantitative measurements. These findings explain the limits of the evidence; they do not mean every patient is a candidate or that these treatments form part of our protocol.
Preparing for surgery
The preoperative consultation establishes whether the main concern is skin, fat, or both; outlines the approximate scar position; reviews previous surgery, medication, allergies, and healing history; and assesses circulation and individual risk.
Preoperative tests and medication instructions are individualized. Do not stop prescribed treatment on your own initiative. Smoking increases wound-healing risks and must be addressed before surgery that depends on a good blood supply to the skin edges.
What recovery after a knee lift involves
Swelling, bruising, tightness, and discomfort when bending the leg are common. Pain management, dressings, and compression are prescribed individually. Short walks usually begin early to encourage mobility without stressing the wound.
Protect the closure
Walk gently, elevate the legs when advised, and avoid deep bending or movements that increase tension.
Wound review
Returning to sedentary activity depends on pain, swelling, wound care, and the ability to maintain comfortable positions.
Gradual activity
Walking and mobility increase according to recovery. Driving requires being able to react and brake without pain or limitation.
Strenuous exercise
Only once the wound is closed and the surgeon gives clearance; combined surgery or a complication may extend the timeline.
Risks and possible complications
In addition to anesthesia risks, possible complications include hematoma, seroma, infection, partial wound separation, widened or hypertrophic scars, sensory changes, asymmetry, contour irregularities, skin changes, thrombosis, or the need for later correction.
Published information on a lift specifically limited to the knee is scarce: a small series of 10 patients described a technique for the lower thigh and knee, but its size does not allow precise calculation of individual risk. It is therefore more honest to combine the available thigh-contouring evidence with examination, informed consent, and clinical experience, rather than present small study figures as a guarantee.
The American Society of Plastic Surgeons lists poor healing, wound separation, seroma, infection, sensory changes, unfavorable scarring, recurrent laxity, and revision surgery among thigh lift risks. Individual risk depends on treatment extent, health, smoking, weight, and associated procedures.
How long does the result last?
Removed skin does not return to its previous position, so correction may be lasting. However, the knee continues to age and may change with weight fluctuations, loss of elasticity, sun exposure, or renewed tissue laxity.
It is not scientifically sound to promise a fixed duration of five or ten years. Stable weight, not smoking, protecting the scar from the sun when appropriate, and attending follow-up help maintain the result, but do not stop the passage of time.
How much does a knee lift cost?
The approximate cost of a knee lift at Dr. Aso Clinic is 5,000 to 7,000 EUR. The final quote is established after assessing the area and depends on the extent of excess skin, whether liposuction is added, anesthesia, operating time, and the need to combine it with another procedure.
The assessment should make clear what the quote includes and, above all, which result and scar are considered reasonable for your anatomy.
Questions about knee lifts, wrinkles, and liposuction
Where is the scar after a knee lift?
With our technique, it is a curved line along the upper border of the knee. Its length depends on the excess skin, and its final visibility on tension, care, and healing.
Can a knee lift be combined with liposuction?
Yes. It can be performed alone or combined with liposuction when localized fat is present alongside excess skin. Liposuction addresses volume; a lift removes skin.
Does knee liposuction remove wrinkles?
Not necessarily. It may improve a fat deposit if the skin can adapt well, but does not eliminate excess skin and may make it more noticeable if the skin is lax.
Is there a nonsurgical knee lift?
Some treatments may produce a modest improvement in skin quality or mild laxity, but do not remove a significant skin fold or offer the same change as excision.
Does Dr. Aso recommend thread lifts for the knees?
No. Dr. Aso does not use or recommend them in this area. Published thread-lift evidence focuses mainly on the face and neck and does not justify promising a lasting result at the knee.
When are before-and-after results visible?
The reduction in excess is noticeable early, but initial swelling and stiffness distort the contour. A useful comparison requires allowing the area to recover and photographing it with the same posture, lighting, and distance.
When can I return to work or exercise?
Sedentary activity may be possible at approximately one to two weeks if recovery is going well. Strenuous exercise usually waits at least four to six weeks and requires clearance once the wound is closed.
Is the knee lift result permanent?
Removed skin does not return, but tissues continue to age and may change with weight and loss of elasticity. This is why we describe a lasting correction, not an unchanging result.
What is the price of a knee lift?
The approximate cost at Dr. Aso Clinic is 5,000 to 7,000 EUR. The final quote depends on the amount of skin, whether liposuction is combined, anesthesia, and the extent of surgery, and is confirmed after assessing the area.
Improving the fold means accepting a scar
A knee lift can address excess skin that liposuction and external treatments cannot remove. The indication is appropriate when the expected contour improvement justifies a curved scar along the upper border of the knee.
