My 89 year old mother had injured her knee ( tibia spinal fracture ) about 12 weeks ago which created a lot of bleeding up and down her leg. Her knee is doing much better now but she has developed a sore on her ankle from the blood not circulating properly. It has turned into a black scab now with a lot of tenderness. She was seen today by wound care specialists and they recommended to debris the scab off so the healthy skin can grow underneath. Is this a good idea considering her age? I am concerned this new open sore will take even longer to heal. Since we did not want this treatment , they sent her home with some gel to put on it and wrapped the ankle and will see her back in 2 days.
