Chondroitin is a chemical found primarily in joint cartilage. A form of chondroitin, known as chondroitin sulfate, is manufactured from animal byproducts and sold as a dietary supplement to aid in the treatment of osteoarthritis.

In a study published Thursday in the journal PLOS One,biochemist Patrick Griffin, Ph.D., and colleague Mi Ra Chang, Ph.D., describe a specific protein that manages activities within chondrocytes, a critical cell type that maintains healthy cartilage in joints.

Although cartilage repair and restoration still pose clinical challenges in orthopedics, the knowledge of cartilage repair and healing gained in the last decade has resulted in advanced surgical techniques and improved outcomes.

A variety of surgical procedures exist to address these injuries, including restoration of articular cartilage injuries with autologous chondrocyte implantation (ACI), osteochondral allograft transplantation (OCA) and reparative marrow-stimulation techniques, such as microfracture.

When surgery is considered for a hip labral tear, the most common way to address this is through arthroscopic treatment.

For patients with femoroacetabular impingement, surgical treatment of labral pathology with femoral osteoplasty yielded better long-term outcomes and survivorship compared with arthroscopy alone.

The labrum is a type of cartilage that surrounds the socket of ball-and-socket joints. A labrum is found in both the shoulder and the hip joint.

Results presented here showed female athletes with femoroacetabular impingement had significant improvements in patient-reported outcome scores and a high rate of return to sport after hip arthroscopy.

The 6-foot-1 guard had arthroscopy a type of minimally invasive surgery on both hips last fall to relieve so-called hip impingement. The condition is ...
