Nose Cells Can Be Used to Repair Knee Joints

Surgeons successfully used an experimental technique, including harvesting nose cells to repair damaged knee joints according to

Between 1999 to 2008,  approximately 6,664,324 knee injuries were reported for a rate of 2.29 knee injuries per 1,000 population. People 15-24 years of age had the highest injury rate, whereas children younger than 5 had the lowest rate reported

Some of the most common knee surgeries currently used include Meniscectomy ,Meniscus Repair, Meniscus Transplant, Plica Surgery, and Lateral Release. A Meniscectomy is the most common surgery and is used when a certain area of the knee called the meniscus is damaged by using an arthroscopic method, which includes several incisions to the knee so a small camera and several tools can be used to remove the meniscus, explained

Meniscus Repair is a surgery used to repair the meniscus instead of a performing a  Meniscus Transplant to replace the meniscus with one from a donor. Another type of common knee surgery is Plica Surgery, used to treat a vulnerable area to injury known as the plica to reduce inflammation and Lateral Release, used to relieve knee pain in the knee cap, according to

The Swedish team was led by Ivan Martin, a professor of tissue engineering at the University of Basel, the oldest university in Switzerland. They grew the harvested cells for two weeks, then cut the cells into the right shapes, and used them to replace the damaged cartilage, reported

The articular cartilage is the tissue cushions the surface of the joint and is necessary for painless movement. This tissue lacks its own blood supply and the damage can lead to joint conditions such as osteoarthritis, which is common in middle aged and older people, according to cbc.a.

After two years of follow up, the patients reported better use of their knees as well as no side effects. However, this study did not include a control group and some of the authors feel that the result may be due to the placebo effect, explained
