Synovial osteochondromatosis is a rare, benign condition characterised by synovial metaplasia and the formation of cartilaginous and osteocartilaginous bodies in the capsule. We report one such case in a 30-year-old woman with synovial osteochondromatosis of the hip and progressive osteoarthritis caused by femoroacetabular impingement with joint-space narrowing. She underwent surgical removal o...

Synovial osteochondromatosis is a rare synovial proliferative disease that occurs because of chondral metaplasia within the synovium. This can occur intra- or extra-articularly. Etiology ultimately unknown. When conservative treatment fails, cartilaginous nodules should be surgically removed. Although it has been reported all over body, cases foot and ankle are far less common. We report case s...

A 31 years old female presented with swelling and pain above the right knee for three years. On examination, there was a tender swelling over the right knee more pronounced over the suprapatellar region. Plain X-ray, US, CT scan and MRI of the knee were suggestive of Primary synovial osteochondromatosis (PSC) of the suprapatellar pouch. Patient underwent total synovectomy and the diagnosis of s...

Arthroscopic excision of synovial osteochondromatosis of the hip is commonly performed. However, when the lesion extends to the extra-articular space of the hip joint, excision using arthroscopy becomes difficult. Although surgical dislocation of the hip with a trochanteric flip osteotomy is commonly used, manual access to the inferomedial portion of the acetabulum remains difficult. In this ca...

BACKGROUND Synovial osteochondromatosis is a benign metaplastic proliferative disorder of the synovium characterised by the formation of multiple cartilaginous nodules in the synovium, many of which detach and become loose bodies. The disease is characteristically monoarticular, most commonly involving the knee. A site in the elbow was first reported in 1918 by Henderson, but any joint may be i...

We present 12 patients with synovial osteochondromatosis of the elbow treated by synovectomy. Histological review showed that seven cases were primary and five secondary osteochondromatosis. The patients with primary disease had a mean improvement in the flexion arc from a preoperative value of 40 degrees to 123 degrees to 5 degrees to 128 degrees when reviewed at a mean of nine years after ope...

The authors report the case of a patient with synovial osteochondromatosis of the knee, who had previously been a soccer player.

Pseudopseudohypoparathyroidism (PPH) is a rare genetic disorder characterized by multiple musculoskeletal anomalies and normal serum calcium, phosphate, and parathyroid hormone levels. Although the musculoskeletal manifestations of PPH are well known, little has been reported on the management of orthopedic problems. We report a case of total knee arthroplasty (TKA) performed in a patient with ...
