Magnetic resonance arthrography (MRA) with radial slices accurately identifies hip adhesions and labral tears in patients with persistent pain after surgery. This imaging technique aids in diagnosing causes of groin pain, improving treatment outcomes.

Area of Science:

  • Orthopedic Surgery
  • Diagnostic Imaging

Background:

  • Persistent groin pain after femoroacetabular impingement surgery can significantly impact patient quality of life.
  • Identifying the precise cause of residual symptoms is crucial for effective treatment planning.

Purpose of the Study:

  • To evaluate the diagnostic performance of magnetic resonance arthrography (MRA) with radial slices.
  • To determine the sensitivity, specificity, and predictive values of MRA for detecting hip adhesions, labral tears, and cartilage lesions.
  • To correlate MRA findings with arthroscopic surgical outcomes in patients with persistent symptoms after open osteochondroplasty.

Main Methods:

  • A case series of 21 patients with persistent groin pain following open osteochondroplasty for femoroacetabular impingement was analyzed.
  • All patients underwent preoperative MRA with radial slices.

Published on: August 4, 2022

  • Surgical hip arthroscopy was performed to confirm MRA findings and address identified pathologies.

    • Main Results:

    • MRA demonstrated 100% sensitivity and specificity for detecting intra-articular adhesions, which were confirmed and surgically removed.
    • MRA showed high accuracy for labral tears (100% sensitivity, 100% specificity).
    • Diagnostic performance for acetabular and femoral cartilage damage varied, with sensitivities of 66.7% and 80%, respectively.

    Conclusions:

    • Intra-articular adhesions are a significant cause of persistent groin pain after hip osteochondroplasty and can be effectively diagnosed with MRA.
    • MRA with radial slices is a valuable tool for identifying intra-articular pathologies, including adhesions, labral tears, and cartilage damage, in this patient population.
    • Surgical release of adhesions identified by MRA led to symptom relief in 18 of 21 patients.
