Area of Science:

  • Orthopedic Surgery
  • Rheumatology
  • Histopathology

Background:

  • Lipoma arborescens (LA) is a rare intra-articular lesion with unknown etiology.
  • It presents as a villous proliferation of synovium with mature fat cells.

Observation:

  • This article details three cases of LA diagnosed in the knee (two cases) and wrist (one case).
  • Clinical presentation included slow-onset painless swelling, persistent joint pain, limited motion, and intermittent effusions post-trauma.

Findings:

  • Histomorphological examination confirmed LA in all patients.
  • The study reviews literature on LA, emphasizing its occurrence in various joints beyond the knee, including the elbow, shoulder, and wrist.

Implications:

  • LA should be included in the differential diagnosis for patients presenting with persistent, unexplained joint symptoms.
  • Arthroscopic synovectomy is presented as a viable and effective treatment option, particularly for larger joints, with a low recurrence rate.
