Brief Summary:
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

Detailed Description:
Objective Evaluation of the kinematic alignment technique for hip prostheses in patient with hip osteoarthritis
Hypothesis the consideration of hip pathoanatomy and lumbo-pelvic kinematic disorder when planning a hip replacement is likely to decrease the risk of prosthetic dislocation and improve patient function and satisfaction
