Was Told Seroma After Liposuction Will Take a Year to Reabsorbing, Should it be Aspirated?

This sounds like normal post op swelling and bruising at 1 week.  If it is entraped blood it can not be aspirated.  I would be patient ;wear your garment and elevate your legs when possible.

Localized swelling following liposuction usually means that you have a seroma (a collection of serum) or a hematoma (a collection of blood).  If a discreet fluid collection can be felt, I will usually aspirate the area and follow the patient closely (at least 3 days/week).  If the swelling is generalized and, in your case, only one week after the surgery, compression garments, elevation and a low salt diet should help as the swelling subsides over time.  If this is a hematoma as you have been told, I would aspirate the blood if possible to minimize the development of scar tissue and decrease the risk of infection.  If the blood has already clotted, then time is your best option and indeed it can take up to one year for this to resolve.  

First, at one weel you are probably very swollen. If you also have a hematoma, at one week it is unlikely that you can have it aspirated. The blood has to liquefy after it has clotted and this takes about 2-3 weeks. You should be ffollowed closely

I do a large amount of liposuction and this is but one of many reasons I rarely recommend repeat liposuction. After initial liposuction, there is always the addition of much scar tissue in the area which makes the procedure more difficult, more bloody, more time consuming, and less satisfactory. 

However, if you have a pocket of fluid, I would definitely drain it. However if you have blood that cannot be drained, then you are forced to follow it and it can indeed take a year to resolve. However, blood collections have an even greater tendency to lay down scar tissue and firmness or even mild irregularity may occur, but the chances are that if you wait long enough you will see improvement steadily occur.

Seroma, or not. Painful swelling with your knees twice normal is unusual and alarming. Immediate attention would be best for you.
Best of luck,

Yes you could but if clotted blood than very hard to aspirate. I recommend lymphatic massage and external ultrasound therapy. 

Swelling following liposuction can take up to a year to resolve. However, if you specifically have a well defined accumulation of fluid or blood it should be aspirated. It is unclear if this is your situation.

To help accelerate the resolution of swelling, you should wear a compressive garment and even elevate your legs as much as possible at night for a couple of weeks.

You need to be followed very, very closely until this starts getting better.  If you were my patient, I would be seeing you twice a week.  If it is a well defined fluid collection, I would consider aspiration and in the case of re accumulation, a drain. Seromas and hematomas left to resorb can leave a lot of scarring behind.   Make sure you keep in close contact with your surgeon. 

It is only one week since your surgery and your swelling is probably is most acute at this time and should improve over the next three weeks and will continue to recede for about three months. Most likely the cause is not a localized seroma that could be aspirated so I would recommend waiting and continue to wear your compressive garment.
