Bicompartmental Knee Arthroplasty
Partial knee arthroplasty has had followers since the 1970s. As the implants for the patellofemoral and tibiofemoral articulations improved, surgeons began to combine the replacements in an attempt to spare the ligaments of the knee, to remove a minimal amount of bone, and above all, to get back the knee to the pristine kinematic conditions. Initially, the surfaces were replaced with individual implants. A monolithic femoral component was designed and has had some limited success. The chapter will review the experience of the European surgeons with the separate components and the American surgeons with the monolithic prostheses.
