Summary

Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) showed improved cartilage quality 3 years after femoroacetabular impingement (FAI) surgery. This contrasts with initial declines, suggesting recovery of joint health post-FAI correction.

Background:

Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) offers noninvasive assessment of cartilage quality.
Previous interim analysis indicated a dGEMRIC index decrease 1 year post-femoroacetabular impingement (FAI) correction, despite positive clinical outcomes.

Purpose of the Study:

To longitudinally evaluate dGEMRIC indices in patients treated for FAI, comparing operative versus nonoperative management.
To track changes in cartilage quality over 3 years using dGEMRIC.

Main Methods:

A prospective, comparative longitudinal study included 39 patients (40 hips) with FAI, divided into operative and nonoperative groups.
Indirect magnetic resonance arthrography was performed at baseline, 1 year, and 3 years.
Deep learning software was used for 3D cartilage models, with dGEMRIC indices calculated for acetabular and femoral cartilage.

Main Results:

The operative group demonstrated a significant decrease in dGEMRIC indices from baseline to 1 year (acetabular: 512 to 392 ms; femoral: 530 to 411 ms; P < .001).
From 1 to 3 years, dGEMRIC indices improved significantly in the operative group (acetabular: 392 to 456 ms; femoral: 411 to 477 ms; P < .001).
The nonoperative group showed no significant changes in dGEMRIC indices at any time point.

Conclusions:

Three years after FAI correction, dGEMRIC indices improved compared to the 1-year follow-up, indicating cartilage quality recovery.
This improvement may be attributed to normalized joint biomechanics or resolution of postoperative inflammatory processes following intra-articular surgery.
