INTRODUCTION Animal models currently used in osteoarthritis-associated pain research inadequately reproduce the initiating events and structural pathology of human osteoarthritis. Conversely, intra-articular injection of collagenase is a structurally relevant model, as it induces articular degeneration both by digesting collagen from cartilage and by causing articular instability, thereby repro...

INTRODUCTION Recent studies have revealed that rapamycin activates autophagy in human chondrocytes preventing the development of osteoarthritis (OA) like changes in vitro, while the systemic injection of rapamycin reduces the severity of experimental osteoarthritis in a murine model of OA in vivo. Since the systemic use of rapamycin is associated with numerous side effects, the goal of the curr...

We demonstrated previously that local, intra-articular injection of an adenoviral vector expressing human tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) in a rabbit knee model of inflammatory arthritis stimulated synovial apoptosis and reduced inflammation. To examine whether intra-articular injection of recombinant chimeric human TRAIL protein (rTRAIL) also induces apoptosis o...

The authors conducted a retrospective study to validate the specificity of intra-articular injection of local anaesthetic to identify the source of pain in patients with coxarthrosis but ill-defined clinical and radiological features. Forty-seven patients received intra-articular injection of the hip joint as a diagnostic procedure. Twenty-four patients showed a positive response with relief of...

Localized herpes simplex (HSV) type II following intra-articular corticosteroid injection is remarkable. We describe a 51-year-old woman with sacroiliitis following a fall. She was treated with an intra-articular injection of 80 mg methylprednisolone into her sacroiliac joint, followed 2 days later by a cluster of herpetiform vesicles adjacent to the injection site. Swab of punctured vesicles d...

Autologous blood injection around the articular capsule and/or into the articular cavity, which is one of the treatments for recurrent temporomandibular joint dislocation, was recently reintroduced. Here, we present the management of recurrent temporomandibular joint dislocation by autologous blood injection in an 84-year-old female. After the treatment, although the right condylar process had ...

AIM Evaluate intra-articular injection of bone marrow concentrate (BMC), followed by platelet-rich plasma (PRP) injection at 8 weeks follow-up in moderate/severe osteoarthritis. DESIGN Single center, retrospective Case Series (n = 125). METHODS Bone marrow was aspirated/concentrated using a standardized technique. Patients received a single intra-articular injection of BMC, with follow-up i...

CONTEXT Corticosteroid is a well-established cause of drug-induced pancreatitis. However, acute pancreatitis from intra-articular injection of corticosteroid has never been described. CASE REPORT A 69-year-old male presented with acute abdominal pain and was diagnosed with acute pancreatitis. The patient had one episode of acute pancreatitis two year earlier. Both episodes occurred after intr...

BACKGROUND Femoroacetabular impingement (FAI) is a condition that is becoming increasingly recognized as a common etiology of hip pain in athletes, adolescents, and adults. However, history and clinical examination are often inconclusive in reaching a diagnosis, while imaging often detects asymptomatic abnormalities. Treatment has traditionally been limited to surgery, with the role of conserva...
