Left tkr意思

"Left TKR" is medical terminology that stands for "Left Total Knee Replacement." This term is used to describe a surgical procedure where the entire knee joint on the left side of the body is replaced with an artificial prosthesis. The procedure is typically performed when the natural knee joint is damaged or worn out due to arthritis or injury, and non-surgical treatments have failed to provide relief.

During a total knee replacement, the surgeon removes the damaged cartilage and bone from the thigh bone, shin bone, and the kneecap, and replaces them with metal and plastic components that mimic the movement of a healthy knee joint. The metal parts are usually made of cobalt chrome or titanium, while the plastic parts are made of high-density polyethylene.

The "left" in Left TKR indicates the side of the body where the surgery is performed. If the surgery were to be performed on the right side of the body, it would be referred to as "Right TKR."
