I had a right knee replacement in April 2019 with complications. There was nerve damage from the knee into the foot and to help with the partial foot drop the hospital PT tried to put me in an AFO brace, but was not done properly and it resulted in a large blister on the outer side of my leg just above my ankle. You can imagine the terror I felt and even after that blister healed I kept breaking out in blisters on the outer side of my leg, the same side that most of the nerve damage was on so I thought there was connection, saw the surgeon multiple times, my primary and went to the wound care center every week for 8 months only to find out 8 months later and one visit to a dermatologist that there was an infection in my leg that no one bothered to test for. But during this time because we were not sure what was causing the blisters we backed off on my rehab which resulted in some scar tissue forming. But the one thing that I have had ever since surgery (and the surgeon says my x-rays look fine) is a jamming feeling in my knee if I try and press up with my foot and my knee is flexed close to 90 degrees and it can be like a sharp pain at times. I have now lost some flexion and am back down to about 85 degrees but has anyone else had that jamming sensation? is it just due to the scar tissue which the surgeon says is permanent and won't suggest any invasive measures to break up? Also has anyone tried vibration to help break up scar tissue?
