Abstract

Subchondral bony cyst, large solitary or multiple cysts in acetabular dome usually exacerbate progression to degenerative osteoarthritis in the hip joint. But it can be treated through arthroscopic intervention. We report two cases that treated by arthroscopic curettage and bone graft for subchondral bony cysts in early osteoarthritis of the hip joint, and it may delay progression to moderate osteoarthritis.

  Fig. 3 (A) Preoperative simple X-ray and computed tomography (CT) image for Case 2. Multiple cysts (arrow) are revealed on the acetabular dome. (B) Postoperative immediately CT image and plain radiograph at last follow-up. The allogeneic bone graft is well maintained at its initial location (arrows).
