I had a lateral release 9 months ago. Surgery went well and I am very mobile, but at the site of the incision I have a persistent feeling of both a swelling and stiffness and also a feeling of looseness of the kneecap and some soreness of the scar tissue inside the knee. I am due to have the other knee operated on in 2 months I would like to know if what I am feeling now is normal 9 months after surgery and when I will be able to tell if the first operation has been successful. I would like to know this before I undertake the surgery of the second knee. Any comments would be welcomed.
