Question: I had a TKR on my right knee in August 2019.beginning in October, 2010, I began having issues such as cellulitis and a red skunk stripe on my leg. I also had a rash that was over 80% of my body and it itched incessantly. I went to the ER, the orthopedic surgeon came in and bent my leg and said it was fine. The other drs. disagreed. I was admitted and given antibiotics for a week. This was repeated 3x until May, 2011 when the surgeon say my blood work and did a cat scan. He said the appliance was loose. In XXXXXXX he found a staph abscess under the kneecap, it was also eating into my tibia bone. He removed the appliance and inserted spacers. I was out in IV antibiotics for five months.i changed surgeons and had the revision done in March, 2012. I had blood and a course of antibiotics for 3 months after the new appliance was inserted. I have normal abilities with bending and flattening the knee joint. I attended PT and was dismissed after 6 weeks. Recently, I have issues with a rash and extreme swelling of the knee after walking of sitting in my desk chair for an extended period. It takes several days of elevation to allow the swelling to decrease. Finally, I have found that I am falling frequently and am unable to get up without assistance. I walk with a limp. It is also impossible to walk up and down stairs without going one stair at a time.my XXXXXXX bone is sore and I appear to have frequent bruises on my knee. The surgeon took a regular X-ray, he said nothing was abnormal and he would see me Ina year. Is this a normal outcome for this much time post-op? I am 59 year old widow in reasonably good health. My children are extremely concerned about my safety.

Is it common to need another revision and is it common to need more than one? What are the probabilities that the same problem will occur?
