Mesenchymal stem cells (MSCs) can be obtained from various tissues, and contain common features. However, an increasing number of reports have described variant properties dependent of cell sources. We examined (1) whether MSCs existed in several intraarticular tissues, (2) whether gene expression profiles in intraarticular tissue MSCs closely resembled each other, and (3) whether identified ge...

BACKGROUND Rheumatoid arthritis (RA) commonly involves the knee joint in up to 30% of patients. Musculoskeletal ultrasound enables the skilled clinician to easily assess disease activity. OBJECTIVE To evaluate the sensitivity to change of the sonography score of large joints in Rheumatology (SOLAR) for different treatments of knee arthritis in RA. METHOD Joints were assessed by ultrasound a...

OBJECTIVE To determine if colour Doppler ultrasonography can characterise the nature of intraarticular echogenic structures and synovial villi more precisely than conventional ultrasonography. METHODS This is a prospective study on 20 patients--10 with rheumatoid arthritis and 10 with osteoarthritis. Colour Doppler ultrasonography of the knee joints was performed prior to total prosthetic rep...

BACKGROUND The anatomic characteristics of the sacroiliac joint (SIJ) make it difficult to achieve intraarticular injection without radiologic guidance. The classic C-arm guided SIJ intervention technique is difficult. Here we describe a new and simple method for SIJ intraarticular intervention. OBJECTIVE This study aims to introduce a new, simple approach for SIJ intraarticular intervention....

As arthroscopic knee procedures have evolved, so has the management of post-operative pain. Traditional pain management included intravenous narcotics, which often resulted in nausea and increased sedation. In an effort to reduce post-operative pain and minimize complications, the concept of multimodal analgesia evolved, including subcutaneous infiltration of local anesthetic, ketorolac and/or ...

background: this double-blinded, randomized clinical trial was designed to evaluate the comparison of intravenous versus intraarticular (ia) administration of midazolam on postoperative pain after knee arthroscopy. materials and methods: in this study, 75 patients randomized in three groups to receive 75 mc/kg ia injection of midazolam and 10 ml intravenous injection of isotonic saline (group i...

An intraarticular osteoid osteoma of the knee is uncommon, and its treatment is challenging. The authors present a case of arthroscopic excision of an intraarticular osteoid osteoma in the distal femur, which was accessible through the knee joint. After confirming the nidus of the osteoid osteoma by computed tomography, the lesion was completely removed arthroscopically. The patient reported co...

This study is to investigate the changes of Temporomandibular Joint (TMJ) by experimentally induced osteoarthritis (OA) and to compare effectiveness of intraarticular injections. Intraarticular Monosodium Iodoacetate (MIA) solution was injected bilaterally to experimental groups to induce TMJ osteoarthritis. 0•9% NaCl solution was injected to TMJ of healthy control group bilaterally to investig...

OBJECTIVE To compare the efficacy and safety of intraarticular glucocorticoid injection to its systemic use for treatment of knee synovitis in rheumatoid patients. METHODS A randomized double-blind controlled study was conducted including 60 patients with RA. Patients were randomized to receive either a single intraarticular knee injection with triamcinolone hexacetonide 60 mg (3 ml) and xylo...

BACKGROUND Although in clinical use, there is only 1 published case report on the efficacy of intraarticular regeneration injection therapy (RIT) (a.k.a. prolotheraphy). This report supports a rationale for future clinical trials of this technique. OBJECTIVE To assess the efficacy of intraarticular zygapophysial joint RIT in patients with chronic whiplash related neck pain that failed other c...
