I got ACL reconstruction surgery about 7 months ago and I have a small bump on my car incision and it gets bigger as I exercise but it is hard and it s not too painful but it does hurt a little bit when I touch it and I could feel it when I walk and run and it hurts when I bend my knee or straighten it out for like flexible hyperextended
Hithank-you for providing the brief history of you. A thorough clinical scar examination is advised. As you have scar post ACL reconstruction you need to get the scar mobility back. As scar is a hard tissue applying a soft therapeutic ultrasound therapy massage with help loosen the scar tissue and dissolve it as well. In my clinical practice such scars are recommended to physical therapy and the scar dissolution is noticed. Regards Jay In Chat Doctor.
