What are the possible complications of an untreated chondral ulcer?

There will definitely be some volume loss after the HA fillers are reabsorbed, but you will not be left worse off than prior to the HA filler injection. This is because besides volume replacement, HA fillers stimulate collagen production as well. This also helps with some volume replacement, as well as improving sagginess and skin texture. Hence even when the HA fillers are reabsorbed, you will return to a skin age/stage which is better, compared to if you had no fillers done.

Hyaluronic acid (HA) fillers can be removed using Hyaluronidase (Hyalase). Usually 1 session is needed. However, for HA fillers that still remain even after 1 year, more sessions may be needed for best results. Hope that this helps!
