Osteoarthritis is a debilitating disease that results in pain and joint stiffness. Currently, steroidal and nonsteroidal anti-inflammatory drugs and supplements aimed at restoring lubrication to the affected joint are the most successful with respect to improving patient comfort. Due to the success in lubricating therapies, there exists a keen interest to develop better therapies that mimic how lubrication occurs naturally in the joint. Here we describe the results obtained using a chondroitin sulfate chain to which is conjugated peptides that bind to either hyaluronic acid (found in high concentrations in the synovial fluid) or collagen type II (present on the cartilage surface). Our study investigates the effect of binding to the cartilage surface and interacting with hyaluronic acid on lubrication at the cartilage surface. The results described here suggest that binding to the cartilage surface is critical to supporting lubrication and did not require the addition of hyaluronic acid to reduce friction.

Laryngeal chondroma is a very rare laryngeal tumor that commonly presents as dysphonia and dyspnea. A combination of clinical, histological, and radiological data has paramount importance for accurate diagnosis of this rare disease. It is difficult to differentiate laryngeal chondroma from chondrosarcoma solely based on radiological imaging; therefore, radiologists need to specify the origin of the tumor and the level of extension.

There is currently no cure or disease-modifying treatment for post-traumatic osteoarthritis (PTOA). This study aims to assess the efficacy of dimethyl fumarate (DMF), a US-FDA approved drug for multiple sclerosis, as a treatment for PTOA. PTOA was induced in male Lewis rats by medial meniscal transection (MMT) surgery, and DMF was intra-articularly administered once, one week following surgery.

CT arthrography (CTA) for evaluating cartilage defects would be beneficial in clinical practice. Since the contrast medium (CM) volume is often driven by operator experience, the aim was to evaluate the minimum volume of iodinated CM for CTA sufficient to identify iatrogenic cartilage defects in horse fetlock. The study was conducted on ex-vivo 32 distal limbs from adult horses collected at slaughter.
