Computer-assisted orthopedic surgery (CAOS) using imageless navigation improved acetabular component alignment accuracy in total hip arthroplasty (THA). This technique reduced variance in cup positioning compared to free-hand placement, enhancing surgical outcomes.

Area of Science:

Orthopedic Surgery
Medical Technology
Biomechanical Engineering

Background:

Acetabular component malpositioning in total hip arthroplasty (THA) leads to complications like dislocation and early loosening.
Optimal cup alignment (40° abduction, 15° anteversion) is crucial for THA success.
Computer-assisted orthopedic systems (CAOS) aim to improve implant alignment reproducibility.

Purpose of the Study:

To compare the accuracy of acetabular component insertion using an imageless CAOS system versus free-hand placement in THA.
To evaluate the effectiveness of Bone Morphing technology for THA cup alignment.

Main Methods:

A prospective, randomized controlled study involving 60 patients (30 per group).
One group received imageless CAOS-assisted cup placement (Bone Morphing technology); the control group had free-hand placement.

The Transition to an Anterior-Based Muscle Sparing Approach Improves Early Postoperative Function but is Associated with a Learning Curve

Published on: September 7, 2022

Postoperative 3D CT scans were used to measure cup abduction and anteversion angles by an independent observer.

Main Results:

No significant difference in mean abduction and anteversion angles between the CAOS+ and CAOS- groups.
The CAOS+ group demonstrated a significantly lower range of variance in cup positioning compared to the CAOS- group.
The mean additional operative time for the CAOS procedure was 12 minutes.

Conclusions:

The imageless CAOS system, utilizing Bone Morphing technology, accurately guided acetabular component insertion in THA.
This CT-free navigation system offers improved precision and reduced variability in cup alignment during THA procedures.
