I fell off my bicycle about two months ago and experienced a significant pavement burn on my knee. Most of it has healed except for an area about 1 inch in diameter that continues to form a thick scab-like covering that then sloughs and bleeds. Will I need a skin graft to close this wound?
User :   hi
User :   DR. XXXXXXXX here
User :   let me read what you have typed
User :   is the area with redness and is there pus coming out of the scab?
User :   No pus, but it is definitely red/purple
User :   ok. is it possible for you to send me a picture of the lesion? if yes, please send it to
User :   for me to have a look to advise if skin grafting is necessary
User :   I could probably do that after this chat. I would need to undress the lesion to take a picture of it.
User :   ok. then i will wait for the picture
User :   please confirm your e-mail ID and contact number
User :   i will answer you my e-mail if necessary
User :   please provide your age, gender, height and weight
User :   is there history of diabetes in family?
User :   My email . No history of diabetes and I have recently had blood studies done to rule that out.
User :   is the bleeding severe when the scab comes out?
User :   My age is 68 years old, I'm female, am 5 feet 5 in tall and weigh 156 lbs.
User :   No, bleeding is mostly oozing with serum and some blood.
User :   are you doing dressing with medications at home?
User :   I've been using a bacitracin plus ointment with a telfa dressing.
User :   ok. continue to do the same. avoid very tight dressing
User :   give rest to the area and minimise your moving around for a few days
User :   to allow for healing
User :   have a high protien diet to facilitate good tissue formation.
User :   I've done all that - keep in mind this injury occurred 8 weeks ago.
User :   yes, that is why I have asked for the picture
User :   since the time gap is too long
User :   it should have usually healed by 6 weeks even if we consider the old age and delayed healing
User :   i will wait for your picture
User :   I have just sent you a picture of my knee lesion.
User :   send it to
User :   address mail
User :   let me see
User :   do not close th chat window
User :   I'm back - did you getg my picture?
Doctor :   Yes i got your picture.
Doctor :   You can continue the dressing as you are doing.
User :   But after eight weeks will I need a skin graft?
Doctor :   Consider using Neosporin powder for dressing . The area needs rest to be healed completely with minimal movement of joint.
User :   How can I do that? Do I need a knee immobilizer?
User :   Where can I get neosporin powder?
Doctor :   If in next 5 to 7 days you do not see any improvement(with use of neosporin powder), then you need to consider it examined by General/ Cosmetic surgeon for decision for the need of skin graft.
User :   /q
Doctor :   You do not need knee immobilizer just have to take rest.
User :   Where can I get the neosporin powder and do I need to immobilize the knee?
Doctor :   It is over the counter antibiotic powder that is available readily on request.
User :   Okay, I'll try that - and I don't need to immobilize the knee, right?
Doctor :   You need to immobilize the knee but without the use of immobilizer.
User :   How do I do that?
Doctor :   Avoid moving around. Avoid flexing and extending the knee unless required.

User :   Okay. Then I should see a doctor if it isn't better in about a week?
Doctor :   Yes a general surgeon or cosmetologist will be better to decide for skin graft if required.
User :   All right. Thanks for your help
Doctor :   Is there anything else you would like to know?
User :   No thanks.
Doctor :   Thanks for consultation, bye for now
