Total Hip Replacement is one of the most common operations
performed in the developed world
today. Anincreasingly ageing population means that the
numbers of people undergoing this operation
is set to rise. There are a numerous number of
prosthesis on the market and it is often difficult to
choose between them. This paper reviews the relevant
anatomical and biomechanical principles in
THA. It goes on to elaborate on the structural
properties of materials used in modern implants and
looks at the evidence base for different types of
fixation including cemented and uncemented
components. Modern bearing surfaces are discussed in
addition to the scientific basis of various
surface engineering modifications in THA prostheses.
The basic science considerations in component
alignment and abductor tension are also discussed. This
article reviews basic science concepts and
the rationale underpinning the use of the femoral and
acetabular component in total hip replacement.
