Review Article

  • ➢ Synovial chondromatosis is a rare, benign condition of unknown etiology in which the synovium undergoes metaplasia leading to cartilaginous nodules that ultimately break free, mineralize, and even ossify.
  • ➢ The most commonly involved joint is the knee.
  • ➢ Patients may be asymptomatic or may present with pain, swelling, and limited range of motion.
  • ➢ Plain radiographs can be diagnostic and mineralized nodules are pathognomonic.
  • ➢ Recommended treatment involves arthroscopic or open removal of loose bodies with or without a synovectomy to prevent further articular and periarticular destruction and to relieve symptoms.
