Isolated synovial chondromatosis of the ankle

20231 citationOpen accessUniversity of Tunis El Manar

In plain language

Synovial chondromatosis is a rare condition where the synovial membrane transforms into cartilaginous or osteocartilaginous tissue, typically affecting young adults around the age of 20. Its occurrence in the ankle is exceptionally uncommon. A clinical case involved a 26-year-old man who experienced six months of recurrent ankle trauma, swelling, and pain. Initial radiographs and arthrography identified calcified foreign bodies and intra-articular effusion. Surgeons conducted an arthroscopy, identifying multiple osteochondromas, and performed a synovectomy. Pathological testing confirmed the diagnosis. While ankle synovial chondromatosis can be managed through open surgery or arthroscopy, arthroscopic intervention provides enhanced joint access, lower morbidity, and faster rehabilitation. However, arthroscopy carries potential risks of incomplete synovectomy or leaving residual loose bodies behind.

Key takeaways

  • Synovial chondromatosis of the ankle is an exceptionally rare condition involving metaplasia of the synovial membrane.
  • A 26-year-old patient with persistent pain, swelling, and trauma history was diagnosed using radiographs, arthrography, and arthroscopy.
  • Arthroscopic synovectomy successfully treated the condition by removing multiple osteochondromas.
  • Arthroscopy offers advantages such as reduced morbidity and quicker recovery, but carries risks of incomplete synovectomy or residual loose bodies.

Why it matters

Synovial chondromatosis can cause chronic joint pain, swelling, and functional impairment in young adults. Because it rarely appears in the ankle, standard diagnosis and management can be challenging. Documenting successful minimally invasive approaches helps orthopaedic surgeons evaluate less traumatic treatment options that shorten patient recovery times while managing the risks of incomplete tissue removal.

Commercialisation angle

Abstract

INTRODUCTION AND IMPORTANCE: At the age of 20, young adults are most susceptible to synovial chondromatosis, a rare condition characterized by the metaplasia of the synovial membrane into cartilaginous or osteocartilaginous tissue. Synovial chondromatosis is exceptionally uncommon in the ankle. CASE PRESENTATION: An orthopedist evaluated a 26-year-old man with a history of recurring ankle trauma over a period of 6 months, swelling and pain. An ankle radiograph revealed calcified foreign bodies, while arthrography displayed enlarged oval bodies with contrasting features and intra-articular effusion encapsulated heterogeneously. Subsequent arthroscopy, following contrast injection, revealed intra-articular contrast effusion. During the arthroscopic procedure, multiple osteochondromas were discovered. A synovectomy was performed, and pathological analysis confirmed the presence of synovial chondromatosis. CLINICAL DISCUSSION: Synovial chondromatosis of the ankle is an exceptionally rare condition with only a handful of documented cases in the literature. Isolated instances of ankle synovial chondromatosis have been reported, and these cases have been managed using both open and arthroscopic techniques. Arthroscopic intervention offers potential benefits such as improved joint access, reduced morbidity, and quicker rehabilitation and recovery. However, arthroscopic surgery might pose the risk of incomplete synovectomy or residual loose bodies. CONCLUSION: Synovial chondromatosis of the ankle represents a chronic and rare ailment. Arthroscopic treatment stands out as an effective and dependable solution, offering various potential advantages over open surgery. This case report is presented due to the rarity and clinical significance of the condition.
