Is there a way to get rid of lumps 10 years post lipo on thighs?

Liposuction lumps and bumps can almost always be improved with further treatments such as micro cannulas liposuction or fat grafting or just fine undermining the fibrous bands or adhesions. 

If the lumps are solitary raised areas, then an attempt at focal liposuction in these areas is worthwhile as they may represent residual fat. If you have indentations adjacent to the raised areas, those indents can be treated by fat injections often with good results but sometimes it is difficult to smoothen the surface. If it's not swelling but fat, and ten years after liposuction it is not swelling, then endermologie and Velashape won't help much.

These are very difficult to remove and may be reflective of loose skin which can only be improved via dermolipectomy (thigh lift) procedures. Discuss this with a plastic surgeon who is comfortable with these procedures. AT this point in time, I am not a strong believer in non-surgical interventions such as mesoltherapy ("fat melters") or radiofrequency,  non-invasive technologies (Thermage or Velasmooth or Alma)
