Windpipe Doc Invents Torn Meniscus Bandage (Orthopedics This Week)
It sounds like a crazy idea but it should be taken seriously because the proponent, Anthony Hollander, M.D., who was involved in the world’s first successful windpipe transplant in 2008. Hollander has used similar technology to develop his latest idea–a stem cell bandage for patients with torn knee cartilage.
The bandage uses a patient’s own stem cells and was developed for commercial use by a Bristol University, England, spin-out company called Azellon Ltd. For the initial phase, Hollander is recruiting 10 patients with torn meniscal cartilage who will have the bandage implanted in their knees in a procedure at Southmead Hospital.
Patients who have been diagnosed with torn meniscal cartilage following an MRI scan will have a small operation to take a sample of bone marrow from their hip. The stem cells taken from the bone marrow will be sent to the lab to grow them on the membrane, called a bio-scaffold, which forms the basis of the bandage. Two weeks later the bandage will be sent back to Southmead for an arthroscopy operation, using a small camera, to implant the bandage into the site of the injury.
Patients will...
