Abstract
The history of prostheses evolution follows a repetitive course of
development and failure. The continuous and rapid developments of
biomechanics and of materials in the 20th century hugely expanded the
information available. Furthermore, spectrums of designs are currently
being used for total knee arthroplasty. Most knee replacements are now
being performed with PCL-retaining or PCL-substituting prosthesis that
have their merits and limitations, as discussed above. New mobilebearingdevices,
which address the issue of functional complexity, have
been developed and have the potential to prolong implant durability.
Nonetheless, prosthesis materials and the historical and current results of
different types of prosthesis remain topics of discussion with respect to
their indications and contraindications.
