[Secondary synovial chondromatosis of the ankle joint]

Ankle synovial chondromatosis: Clinical, radiological, and surgical findings: A case report

Synovial chondromatosis is a rare benign condition defined by the presence of cartilaginous lesions in the synovium of joints, tendon sheaths, and bursae. It most typically affects large joints, such as the knee, hip, and shoulder, but it is also reported in smaller joints. Nonetheless, ankle involvement is relatively uncommon. A complete history and clinical, physical, and radiographic examinations are usually used to determine the diagnosis. Hence, we reported a case of a young patient with left ankle primary synovial chondromatosis who presented with a left ankle mass and chronic pain.

Arthroscopic surgery for synovial chondroma of the subacromial bursa with non-traumatic shoulder subluxation complications: Two case reports

BACKGROUND

Synovial chondromatosis is a disease originating from the synovium and characterized by the presence of metaplastic cartilaginous nodules in synovial cavities. The exact prevalence of synovial chondromatosis remains unknown, and the involvement of the shoulder joint is very rare. Synovial chondromatosis accompanied by subluxation of the humeral head without a history of trauma is rarely encountered, and to our knowledge, no published reports describe this condition.

CASE SUMMARY

We present two cases of synovial chondromatosis in the shoulder joint, accompanied by subluxation of the humeral head, in two arthroscopically managed adult patients. We performed arthroscopic labrum fixation and removal of the loose body from the shoulder joint. To identify primary and secondary categories, pathological analysis was arranged. Clinical and radiographic evaluations at the 1-mo follow-up were satisfactory.

CONCLUSION

The biomechanical function of the shoulder joint requires attention, especially following the detection of loose bodies, as observed with synovial chondroma occurring in rare sites. Arthroscopic management is successful in patients with synovial chondromatosis combined with shoulder subluxation.

Arthroscopic Management of Anterior Ankle Synovial Osteochondromatosis

Surgical treatment has been recommended as the first choice of therapy in second and third stages of the disease. Complete synovectomy and removal of all loose bodies is advisable for prevention of recurrence of the disease. Recently, arthroscopic treatment of synovial chondromatosis is gaining popularity because of its favorable outcomes and very low complication and recurrence rates. Arthroscopic approach also allows management of concomitant pathology. The purpose of this Technical Note is to describe the technique of arthroscopic synovectomy and removal of loose bodies as treatment of synovial chondromatosis localized in the anterior compartment of the ankle joint.

Tenosynovial Osteochondromatosis of the Flexor Hallucis Longus Tendon Treated by Tendoscopy

Tendosynovial chondromatosis of the foot and ankle is a rare disease entity. We reported 3 patients with tenosynovial osteochondromatosis of flexor hallucis longus. They were successfully treated by arthroscopic synovectomy and removal of the loose bodies.

Arthroscopic treatment of synovial chondromatosis in the ankle joint

INTRODUCTION

Synovial chondromatosis is characterized by the presence of metaplastic cartilage nodules originating from the synovia, bursa and tendon sheaths. Although it is extremely rare in the ankle joint, malignant transformation is possible. The choice of treatment is usually open surgery for excision of loose bodies and synovectomy. Limited data is available concerning arthroscopic approaches.

PRESENTATION OF CASE

A 28-year-old male patient was evaluated for pain and swelling of the right ankle joint. Based on the findings of physical examination and radiographic investigations, arthroscopic surgery was performed due to ankle impingement syndrome. A diagnosis of synovial osteochondromatosis was made following the pathological survey.

DISCUSSION

Synovial chondromatosis is slowly progressive and is considered to be a self-limiting situation. Treatment strategies are decided on according to the patient's complaints, age and disease stage. Open or arthroscopic surgery. can be performed. Some advantages of arthroscopic surgery are wide visualization areas, easy access to areas difficult to reach, lower morbidity, no necessity for casting and immobilization, early rehabilitation and quick recovery period.

CONCLUSION

In conclusion, arthroscopic management can be successful in selected patients with synovial osteochondromatosis localized to the ankle joint.
