Hi also from me. I was looking for a solution for my problem (recovering the muscle after the hematoma removal), but it looks like nobody in this forum went that far.
I had my contusion and the subsequent hematoma in 1994. I had a small lump on the upper part of my outer thigh for 16 yrs...Finally, in 2010 decided to have it removed. The first surgeon who had to operate it cancelled the appointment due to a fear that the hematoma could be still alive and that would create some complications. He recommended another clinic where the surgeon was braver.
The result is that I don't have the lump anymore, and don't have pain. Unfortunately, however, I pretty much also don't have any vastus lateralis muscle left. The VL muscle on the left thigh was not as strong as the right one ever since the injury, but now I feel the middle part of the VL pretty numb. I guess, it was due to having some nerve cells being removed during the surgery. I've been cycling quite a lot after the surgery but, as you can see from the attached photos, it didn't help fill in the emptiness in the VL. The overall result is that the other quad muscles hypertrophated in order to compensate for the missing one. One physiotherapist told me that the hypertrophated muscles press the VL and don't allow it to recover properly...
The truth is that I never found the time to make physiotherapy/massages only on the VL. Probably, it would have helped. Not sure.
I plan to make another round of examinations in the coming days and get some professional advice how to finally recover the VL at the 20th Anniversary of the injury....
I will post further, if there's any progress.
Hope, this helps!Removed Hematoma_1.jpg
