An alternative to hip replacement surgery may be in sight. In the Proceedings of the National Academy of Sciences, researchers reveal how it may be possible to use a patient's own stem cells to grow new cartilage in the shape of a hip joint.
Furthermore, the team - including researchers from Washington University School of Medicine in St. Louis, MO - says it is possible to program the newly grown cartilage to release anti-inflammatory molecules, which could stave off the return of arthritis - the most common cause of hip pain.
According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), osteoarthritis is the primary cause of hip joint damage that requires hip replacement surgery, causing severe pain and disability.
Hip replacement surgery, also known as arthroplasty, involves surgically removing the diseased part of the hip and replacing it with new, prosthetic parts. Each year in the United States, more than 332,000 hip replacement surgeries are performed.
