As per a latest study, in near future people who suffer from the problems of the knees and hips would be able to grow new replacement joints. The same would enable the patients to forego repeated surgeries, which are needed following the replacement of the original knee or hip joints.

The study that was carried out for the first time by an American team has made way for the phenomenal advancement, which would enable people to grow inside their bodies, bone and cartilage.

Reports confirm that the study was carried out on 10 rabbits wherein the scientists used a computer, in order to create artificial frames. The same were made keeping in mind the size and the shape of the hip joints of the rabbits.

Further, the scientists ensured that the frames made were filled with a growth hormone and the same was introduced in the bodies of the rabbits, following the removal of the hip joints.

It was observed that due to the attraction in the growth hormone, the stem cells of the rabbits’ bodies located it, went to the particular location and reproduced bone and cartilage in two different layers.

Post the surgery, it was observed that the 10 rabbits had completely regained their natural movement in about three to four weeks. Also, they could also tolerate the same weight compared to the other animals, which had never undergone surgery.

Commenting on the study, Lead Researcher, Professor Jeremy Mao of New York's Columbia University, said, “This is the first time an entire joint surface was regenerated with return of functions including-weight bearing and locomotion”.

In addition, in patients who need the knee, shoulder, hip or finger joints regenerated, the rabbit model provides a proof of principle.

The study has been published online in The Lancet medical journal.
