BACKGROUND: Although chondral or osteochondral injuries are usually assessed by magnetic resonance imaging, its accuracy can be low, presumably related to the relatively thin cartilage layer and the close apposition of the cartilage of the talus and tibial plafond. We hypothesized that axial traction could provide a contrast between the articular cartilage and joint cavity, and it enabled the simultaneous evaluation of cartilage and subchondral bone. The purpose of this study was to assess the feasibility of using computed tomography (CT) imaging with axial traction for the diagnosis of articular cartilage injuries...

Hip arthroscopy is an evolving procedure and its indications have expanded. The number of patients undergoing this procedure has increased significantly as well as the number of surgeons being trained. This has resulted in a notable increase in post-operative complication rates creating the need to develop advanced hip arthroscopic techniques. Revision hip arthroscopy is often complex and many factors should be considered to achieve a satisfactory clinical outcome. Careful pre-operative planning and agreement of expectations between the physician and patient regarding the procedure are important...

Nodular tenosynovitis usually affects the hands and it represents a benign pathology with locally aggressive behavior. Its etiology could be related to chronic inflammatory processes such as trauma, metabolic disturbance, and joint diseases. Histopathological analysis is required for a diagnosis of certainty and surgery represents the treatment of choice. There are no cases in the literature that describe a nodular tenosynovitis affecting the temporomandibular joint (TMJ) The main aim of the present report therefore, is to describe this unusual case and to show the utility of arthroscopic procedures in managing intra-articular tumors of the TMJ...

BACKGROUND: The United States has a growing opioid epidemic impacting all aspects of health care including orthopaedic surgery. Septic arthritis of the knee is a condition commonly encountered by orthopaedic surgeons related to opioid and injection drug use (IDU). Changes in the frequency of hospitalizations for IDU-related septic arthritis and differences in septic arthritis patient outcomes according to IDU status in the setting of the burgeoning opioid epidemic are unknown. QUESTIONS/PURPOSES: (1) What proportion of patients with septic arthritis of the knee use injection drugs? (2) Are there any differences in complications, reoperations, length of stay, and leaving against medical advice among patients with septic arthritis of the knee with and without IDU? (3) What are the age and racial trends in IDU-related septic arthritis of the knee from 2000 to 2013? METHODS: The Healthcare Cost and Utilization Project, Nationwide Inpatient Sample database of years 2000 to 2013 was utilized for patients between ages 15 and 64 years with a principal discharge diagnosis of native septic arthritis of the lower leg, the vast majority of which represents the knee...

Patellar dislocation is a condition that is often reduced by itself or through closed manipulation from a trained professional. In this case of a traumatic lateral patellar dislocation, the patella was caught through the rupture in the lateral retinaculum, as is seen in Boutonniere-like lesions. Reduction of the dislocated patella was obtained by arthroscopic reduction.Level of evidence V.
