As of 2015, the average hospital charge for full knee replacement surgery in the United States hovers around $49,500. The total cost depends largely on the type of implant inserted, whether the surgery used any customized equipment, any pre-existing conditions the patient may have and unanticipated complications, according to Healthline.com.
In addition to the cost of surgery, inpatient and outpatient charges also contribute to the overall cost of full knee replacement surgery. Inpatient charges consist of charges that occur during the patient's stay in the hospital, and costs range up to $7,500, bringing the total cost to $57,000. Outpatient charges pertain to charges that occur before and after a patient's hospital stay, such as office and lab visits, physical therapy, and follow-up visits. Ultimately, the out-of-pocket cost for patients with Medicare usually extends into the hundreds, while the cost for those with private insurance extends into the thousands, explains Healthline.com.
