The Plica Syndrome: Diagnostic Value of MRI with Arthroscopic Correlation

Arthroscopic Treatment of a Symptomatic Hip Plica

“…As reported previously, for knees, plica syndrome is difficult to diagnose without the aid of arthrography, MRI, arthroscopy, or both. 5,10,17 As the use of these tools has increased, so has the apparent incidence of symptomatic knee plicae. 5,16 For the hip, the use of arthroscopy and arthrography has lagged behind, but as these procedures become more common, the diagnosis of hip plica also may be reported more frequently.…”

The Plica: Is a New Aetiological Factor in the Knee Osteoarthritis?

“…It had been hoped that the advent of MRI would be useful in aiding the diagnosis of a pathological plica. Although it has been able to demonstrate plica reliably, it has not been able to predict the necessity of excision of that plica at arthroscopy, which limits its use as a screening tool (46)(47)(48)(49)(50)(51). Arthroscopy is still the gold standard modality to diagnose pathological medial plica.…”

Synovial Plicae in the Knee

“…In 1983, CT arthrography was found to be able to reveal the medial plica [11]. MR images show plicae as low-signal-intensity bands of varying sizes found in the regions in which the plicae are anticipated to be located [12,13].…”
