Dan Ryan obtained a defense verdict for an orthopedic surgeon in Delaware County. The plaintiff underwent a total right knee replacement in 1997, by the orthopedic surgeon. The plaintiff did very well with her knee implant for a period of almost five years. In 2002, the plaintiff began to experience right knee pain and it was found that the right knee implant had loosened. As a result, the plaintiff underwent a second knee replacement surgery to the right side. The plaintiff claimed that this loosening was caused by the way that the knee was aligned during the 1997 surgery, and also because the knee prosthesis used was too large. The defense maintained that the 1997 surgery exceeded the standard of care and that the loosening of the knee implant was not caused, in any way, by the technique used in the previous surgery. Following a two day trial and thirty minutes of deliberation, the jury agreed, and found that Mr. Ryan’s client was not negligent.
