I have had clicking in my left knee since 3 months post op. I am now 23 months post op. I have been told by 3 different doctors that this normal. One said to live with the pain, another said he would try arthroscopic surgery with 50-75% chance of less pain and third said I need a revision. Doesn’t seem normal to me! Nothing ever mentioned about the spacer being inappropriate. X ray and bone scan look fine but still have persistent lateral exterior pain with walking, swimming and going down stairs. Tried MFR, nothing. Taping seems to be the most effective pain relief but you can’t have tape on all the time. One pain doc wants to implant a peripheral nerve stimulator in my leg but not interested. To see another pain doc next week for some type of manipulation but not sure what can be done at this point in time. Ugh!!
