Editorial Commentary: Periacetabular Osteotomy for Hip Dysplasia May Result in Paralabral Cyst Resolution Despite Persistent Labral Tearing.

Paralabral cysts in the acetabulum often occur in the setting of labral tears. While labral tears are commonly identified in femoroacetabular impingement syndrome, developmental dysplasia of the hip is also a cause of chondrolabral pathology. Our understanding of paralabral cysts has encouraged addressing the concomitant labral pathology, as this has been shown to result in cyst resolution. However, recent evidence suggests in the setting of hip dysplasia, addressing the bony pathology of the acetabulum with an isolated acetabular reorientation osteotomy allows for cyst resolution and significant improvement in clinical outcomes despite persistent labral tears postoperatively. While further investigation is needed to delineate the effects of persistent labral tears after isolated periacetabular osteotomy, addressing the acetabular undercoverage remains critical in the treatment of these patients.
