Synovial chondromatosis is an uncommon benign neoplasm that usually affects large appendicular joints and only rarely the spine. There are only a few small series and case reports documenting malignant transformation of synovial chondromatosis into secondary chondrosarcoma, typically within the hip in the setting of recalcitrant disease and multiple recurrences. Chondrosarcoma arising in synovial chondromatosis of the spine is exceedingly rare, with only one previously published case report involving the craniocervical junction. Read More

Hip arthroscopic surgery has become a common technique during the past decade, leading to an increased number of arthroscopic hip revision surgeries. This study aimed to evaluate the clinical outcomes in a series of revision hip arthroscopies to analyse the causes of reoperation in the short to medium-term follow-up. We retrospectively analysed 22 patients who underwent arthroscopic hip revision surgery in our institute. Read More

Rationale: Carpal tunnel syndrome (CTS) is the most common peripheral nerve neuropathy resulting from compression of the median nerve as it traverses the carpal tunnel. The pathophysiology of this condition is multifactorial, and majority of cases of CTS are idiopathic. We report cases of CTS caused by synovial osteochondromatosis (SOC), which has rarely been reported. Read More

Synovial osteochondromatosis is a benign neoplastic condition which manifests as multiple cartilaginous or osteocartilaginous nodules within a joint, bursa and tendon sheath. It typically results in pain and stiffness of the affected joint, and is thought to arise as a result of synovial membrane proliferation and metaplasia. We report the diagnosis and management of a 36-year-old man who presented with a long history of shoulder pain, which had been managed conservatively prior to referral to orthopaedics. Read More

Methods: From 2008 to 2016, 13 patients with synovial chondromatosis of the hip were treated with arthroscopic removal of loose bodies and synovectomy using three arthroscopic portals. An extensive capsulectomy was performed to allow the remaining loose bodies to be out of the extracapsular space, and the excised capsule was not repaired. Read More

Alkaptonuria (AKU) is a rare autosomal recessive disorder that results from the deficient activity of homogentisate 1,2-dioxygenase and leads to increased levels of homogentisic acid (HGA) and its oxidized product benzoquinone acetic acid (BQA). Both HGA and BQA form polymerized deposits that lead to a bluish-black discoloration of the cartilage as well as degeneration, inflammation, and calcification of the tendons, ligaments, intervertebral discs, and large joints and increased bone resorption. A brittle and fragmented cartilage forms and leads to aberrant loading of the subchondral bone. Read More

Intra-articular (IA) and peri-articular (PA) tumors of the knee are frequently encountered by orthopaedic surgeons. Nonetheless, due to the possibility of great morbidity and potential mortality, it is important to recognize and differentiate between benign and malignant lesions in a timely manner. Therefore, the purpose of this article is to provide a concise, practical, and updated review of commonly encountered IA and PA tumors including intratendinous gout, synovial chondromatosis, schwannoma, pigmented villonodular synovitis, and synovial sarcoma, and a detailed description of differentiating features to include various imaging modalities.

In order to treat synovial chondromatosis in minimally invasive way, the loose bodies in the joint cavity should be removed with arthroscopic surgery. However, since the joint cavity is narrow and round, it is difficult to approach with conventional straight surgical tools. To overcome this, existing studies have proposed motorized steerable surgical instruments, but they do not provide haptic feedback and intuitive understanding of the position of the end-effector.

Synovial chondromatosis is a rare proliferative disease, characterized by the occurrence of metaplasia in the synovium of the joints. These lesions become pedunculated; with the evolution of the disease they become detached, leading to intra-articular loose-bodies. It occurs more frequently in males between the third and fifth decades of life, usually affecting large joints such as the knee and hip. Read More

Even though the diagnostics of rheumatic joint diseases are mostly based on clinical, immunoserological and imaging criteria, histopathology can also make a significant contribution. This is particularly true for clinically unclear monoarticular and periarticular diseases. The contribution of histopathology to the diagnosis of rheumatic diseases is manifold since the histopathological differential diagnosis includes the complete spectrum of synovial diseases.

Synovial chondromatosis is a benign disease which most commonly appears in large joints and only rarely affects the temporomandibular joint. The diagnosis is quite difficult due to the fact that a large swelling in the preauricular area and the radiographic findings may be misdiagnosed as other benign or malignant diseases.

Magnetic resonance images showed advanced destruction of the right articular disc anteriorly displaced, condylar erosion, and distinct nodules within an extremely expanded inferior joint compartment with large amount of fluid, as well as a large TMJ effusion. A scintigraphy showed elevated bone uptake in the right TMJ, demonstrating intense bone remodeling activity in the region. Read More
