BACKGROUND Incorrect cup positioning in primary total hip arthroplasty is known as a risk factor for early implant failure. The use of navigation systems leads to more accurate cup positioning. OBJECTIVE The aim of this study was to compare the registration accuracy of the anterior pelvic plane and the measurement accuracy of the definite cup position for a pointer computer-assisted orthopaedic navigation system (P-CAOS) and an ultrasound-based navigation tool (US-CAOS) in an intra-individual…

TLDR
Use of an imageless navigation system can improve cup positioning in total hip arthroplasty by reducing the percentage of outliers.
Cup Alignment Error Model for Total Hip Arthroplasty
TLDR
Simulation results indicate that a total error of 4 mm in measuring the anterior superior iliac spine and the pubic tubercles would result in a final cup orientation of 47° and 27° in abduction and version respectively, resulting in a 2° abduction error and 7° error in version when targeting 45° abduction and 20° version results.
Imageless navigation for insertion of the acetabular component in total hip arthroplasty: is it as accurate as CT-based navigation?
TLDR
Both CT-based and imageless navigation showed a significant reduction in variation of the position of the acetabular component compared with conventional freehand arthroplasty (p < 0.001).
The accuracy of free-hand cup positioning - a CT based measurement of cup placement in 105 total hip arthroplasties
TLDR
It is concluded that a safe position as defined by Lewinnek et al. was only achieved in a minority of the cups that were implanted freehand, and only 27/105 cups were implanted within the limits of the safe position.
No difference in clinical outcome, bone density and polyethylene wear 5–7 years after standard navigated vs. conventional cementfree total hip arthroplasty
TLDR
Standard “cup first” THA navigation does not improve mid-term functional outcome, bony ingrowth and/or polyethylene wear, and new concepts in computer-assisted THA, considering cup and stem as coupled biomechanical partners are needed to justify the effort of navigation in routine operations.

TLDR
A study in a large single-surgeon patient cohort to determine the incidence of early postoperative dislocation with increased acetabular anteversion and the accuracy of imageless navigation in achieving target acetABular position found no relationship between dislocation and component placement in either the Lewinnek zone or the target zone.

TLDR
There is a clear need to develop more reliable tools than were used or anatomically based alignment strategies to provide reproducible and accurate acetabular alignment.
