New knee implant saves the ligaments
A new total knee replacement that saves all of the ligaments can make a person’s knee feel and move just like the original.
During a traditional total knee replacement, the surgeon must remove the "island" of bone to which the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL) are attached. The new knee features a shape that protects that island of bone and saves the ligaments.
