Background
- In the 19th century, Sir John Charnley successfully introduced total joint
replacements for hips. In order to prevent implant fixation failure and accelerated
polyethylene wear, it was initially recommended that implants were systematically
positioned in a "biomechanically-friendly" way, which disregarded most of the
individual anatomy (medialized acetabular cup, systematized cup version and
inclination, etc.)
- While those initial surgical techniques made popular and clinically successful total
joint replacements, many complications (aseptic loosening, pain, excessive wear)
have remained and mainly the persistence of frequent instability after THA. In
response to those complications, many improvements were developed in the area of
joint replacement over the last few decades, with one the most recent dating from
2017 and being the development of a surgical technique Rationale
- The kinematic alignment (KA) technique for total hip arthroplasty (THA) aims at
restoring the acetabular center of rotation and as much as possible the
constitutional acetabular anteversion by using the transverse acetabular ligament
(TAL) as a reference landmark. Also, the technique aims (1) at making personalized
choice for the hip component design, (2) at defining the cup positioning, and (3) at
sometimes considering additional spine surgery based on the assessment of the
individual spine-hip relation.
- KA techniques for hip replacements are relatively new, likely to become popular over
time, and their true value remains to be determined.
