Posterior Stabilized Total Knee Arthroplasty: is it a more forgiving solution

The posterior stabilized design in TKA was introduced in the mid-1970s. Surgeons who use this system believed that the results obtained are more consistent because they do not have to rely on abnormal PCL morphology. Consequently ,exposure, joint line restoration and appropriate balancing of the knee are easier with PCL stabilized designs. These components are a popular treatment for patients requiring primary TKA, particularly in the US and in Asia. Complications like luxation over the jumping distance, post breakage, loss of proprioception, patellar clunk have been reported.
Improvements in implant design, a technically easier procedure in the face of deformity, restoration of knee kinematics and reported very good long-term outcomes may all be reasons for the increased use of this design that nowadays stays as a much more forgiving solution than cruciate retaining designs.
