The Orthopedic and Sports Performance Institute (OSPI) in Arizona is now offering ConforMIS customized knee replacement implants.

The implants offer a custom fit, with implants made according to the patient’s specific anatomy, the institute said.

Many patients from around the country arrive and have an outpatient procedure known as a Rapid Recovery knee replacement. Patients often go home the same day, and then are visited by a nurse as an outpatient each day, OSPI said. This is different from a regular inpatient stay in a hospital of two to four days. OSPI said its procedure speeds up recovery time and patients have less pain.
