The pursuit of ideal biomaterials in the field of orthopaedics is an ongoing process that is driven
by the requirement for improved biocompatibility, mechanical congruence with natural tissues,
and long-term stability in vivo. Polymer-based composites, also known as PBCs, have emerged
as highly attractive options. These composites offer a one-of-a-kind combination of features that
can be customised, which addresses many of the constraints that are associated with standard
ceramic and metallic implants. The purpose of this abstract is to investigate the multifarious
function that PBCs play in a variety of orthopaedic applications. These applications include load-
bearing internal fixation devices and joint prostheses, as well as improved scaffolds for bone
regeneration and smart drug delivery systems. The bioactive modification capabilities of these
materials, as well as their tunable stiffness, radiolucency, increased fatigue resistance, and the
ability to promote osseointegration and lower the risk of infection, are of particular importance.
In spite of the substantial progress that has been made, there are still obstacles to overcome in
order to achieve long-term degradation control, optimised tissue regeneration, and robust
resistance to wear under physiological conditions. In order to unlock the full therapeutic potential
of PBCs, ongoing research is utilising advanced manufacturing techniques such as 3D printing,nanotechnology, and bio-functionalization. This holds the promise of a future in which
orthopaedic solutions that are more durable, personalised, and biologically integrated will
significantly improve patient outcomes.
