INTRODUCTION Osteoarthritis is the most common form of arthritis. It is a slowly progressive joint disease typically seen in middle-age to elderly people. Intra-articular injection of hyaluronic acid is a well-documented treatment for knee osteoarthritis. Celebrex(®) (celecoxib) is a novel nonsteroidal anti-inflammatory drug, which could help to reduce inflammation and to reduce pain. The aim o...

BACKGROUND Intra-articular injection of hyaluronic acid (HA) is a well-documented treatment for knee osteoarthritis (OA). One of the multifactorial mechanisms is that exogenous HA can stimulate endogenous HA production. HA can regulate the growth and function of chondrocytes by binding to CD44 receptors on the chondrocytes. Synovitis is often found in patients with rheumatoid arthritis (RA) and...

Arthritis is a common disease affecting the temporomandibular joint. The inflammation causes local pain and decreased function of the masticatory system. Temporomandibular joint arthritis can result from mechanical overloading, general autoimmune disease or individual susceptibility. The aim of this study was to investigate objective and subjective treatment results after intra-articular inject...

Introduction: Although, the effect of direct intra-articular injection of bone marrow stem cells (BMSCs) on the repair of articular cartilage and the effect of Elaeagnus angustifolia extract on pain relief in patients with osteoarthritis have been investigated, no studies has been conducted to compare the effects of these two therapeutic methods on the mechanical properties of articular cartila...

Intra-articular therapies, such as steroid injection, viscosupplement injection and acupuncture, are common non-surgical options for patients with osteoarthritis of the knee. With any intra-articular injection or acupuncture procedure, there is a potential for inoculation with bacteria leading to possible knee infection. The authors report a patient who incurred an acute infection found after a...

We investigated 15 patients with painful hip arthroplasties using intra-articular injection of bupivicaine. Fourteen had pain relief and 13 of them were subsequently found to have loosening of one or both components. The relief of pain after total hip arthroplasty by intra-articular injection of bupivicaine indicates that a satisfactory result is probable after revision surgery with refixation ...

An outbreak of methicillin-susceptible Staphylococcus aureus joint infections occurred at an outpatient radiology center. We identified 7 case patients; all had undergone magnetic resonance arthrograms with intra-articular joint injections. The outbreak was likely due to unsafe injection practices in preparation of contrast solution for intra-articular injection.

We describe a case of septic arthritis caused by Pseudomonas aeruginosa in an immunocompetent patient following intra-articular ozone injection into the knee. To the best of our knowledge, and after considering the current literature,we believe this case is unique as no other reports of septic arthritis caused by P. aeruginosa following intra-articular ozone injection has been made.

Background: Intra-articular injection of Platelet-rich plasma (PRP) is an effective method for the treatment of patientswith knee osteoarthritis (OA). This study aimed to assess the effects of PRP injection on OA, based on gene expressionanalysis.Methods: A sample of 30 subjects with knee OA was asked to complete the Persian versions of the Intermittent andConstant Osteo...
