From your inquiry, you seem to be asking whether you may have a medical malpractice claim against the surgeon who performed your TKR. I cannot answer this question with the information provided. Generally, to prove a medical malpractice claim you will need an expert in the same practice area of the doctor who you are targeting to review all the records, maybe examine you, and then complete an affidavit to the effect that the target doctor breached the standard of care, the specifics of the breech, and that the expert is willing to so testify in Court.  Generally, just to get records reviewed will cost you between $2-3,000 in up front expense money.
