Abstract
A method of surgically implanting a human knee prosthesis is provided where (i) the postoperative ratio of the adjusted patellar tendon length to the prosthetic patellar height (APL/PH') is from about 1.2 to about 0.9; and (ii) the tibial component of the knee prosthesis is implanted so that the postoperative anterior/posterior center line of the tibial component is located posterior with respect to the preoperative anterior/posterior center line of the tibial plateau by an amount equal to or greater than about 5% of the anterior/posterior distance of the tibial plateau. An implanted prosthetic human knee joint is also provided having either or both the normalized APL/PH' ratio or the 5% posterior placement.
