New technology into joint cartilage repair

Humans like to push their limits, and often that results in damage to joints. This can be through sports, work, accidents, or arthritic disease.

Cartilage is the pad that allows smooth joint operation and keeps bones separated from rubbing against each other. But cartilage doesn’t really repair itself very well at all and when damage happens, there’s been mitigated success in surgery to correct it.

A new process has great promise and is about to begin clinical trials in several locations including London Ontario.

Dr Alan Getgood (MD, FRCS) is involved in this new technology. He is a professor at the Schulich Faculty of Medicine and Dentistry at the University of Western Ontario, and consulting orthopaedic surgeon at th Fowler-Kennedy Sport Medicine Clinic, both located in London Ontario.

When cartilage is damaged, unlike bone, or skin or muscle, it doesn’t heal well, or at all in some cases. A damaged cartilage also often causes pain as the joints move and the irritation causes swelling.

Typically an injection is given to reduce the swelling and pain. In other cases, a surgical process attempts to get the bone to create cartilage, while another process uses cartilage from a cadaver. While the injections certainly help, they do not repair the damage. The cadaver cartilage provides good results, but suitable donor cartilage is difficult to obtain.

The new technique has been under development for quite some time, but holds great promise.

It involves taking a small biopsy of the patient’s own cartilage, and then certain cells (chondrocytes) ,are used to actually grow healthy new cartilage which can then be inserted back into the patient.

Besides being healthy new cartilage, it is also the patient’s own cells so there is no chance of rejection, and the time frame for the cartilage availability is a known factor, which is not the case with a cadaver donor cartilage.

While stem cell research continues with promising results in other areas of medicine, Dr Getgood notes that with cartilage, the problem is to get the stem cells to create the specific cells desired. He says efforts in creating cartilage have not been entirely successful.

Although theoretically very promising, practical usage could still by some years away. The clinical trial in this new technology is set to begin and trial patients will be followed for three years to determine results.

Netiquette »

When you express your personal opinion in an online forum, you must be as courteous as if you were speaking with someone face-to-face. Insults and personal attacks will not be tolerated. To disagree with an opinion, an idea or an event is one thing, but to show disrespect for other people is quite another. Great minds don’t always think alike—and that’s precisely what makes online dialogue so interesting and valuable.

Netiquette is the set of rules of conduct governing how you should behave when communicating via the Internet. Before you post a message to a blog or forum, it’s important to read and understand these rules. Otherwise, you may be banned from posting.

  1. RCInet.ca’s online forums are not anonymous. Users must register, and give their full name and place of residence, which are displayed alongside each of their comments. RCInet.ca reserves the right not to publish comments if there is any doubt as to the identity of their author.
  2. Assuming the identity of another person with intent to mislead or cause harm is a serious infraction that may result in the offender being banned.
  3. RCInet.ca’s online forums are open to everyone, without regard to age, ethnic origin, religion, gender or sexual orientation.
  4. Comments that are defamatory, hateful, racist, xenophobic, sexist, or that disparage an ethnic origin, religious affiliation or age group will not be published.
  5. In online speak, writing in ALL CAPS is considered yelling, and may be interpreted as aggressive behaviour, which is unpleasant for the people reading. Any message containing one or more words in all caps (except for initialisms and acronyms) will be rejected, as will any message containing one or more words in bold, italic or underlined characters.
  6. Use of vulgar, obscene or objectionable language is prohibited. Forums are public places and your comments could offend some users. People who use inappropriate language will be banned.
  7. Mutual respect is essential among users. Insulting, threatening or harassing another user is prohibited. You can express your disagreement with an idea without attacking anyone.
  8. Exchanging arguments and opposing views is a key component of healthy debate, but it should not turn into a dialogue or private discussion between two users who address each other without regard for the other participants. Messages of this type will not be posted.
  9. Radio Canada International publishes contents in five languages. The language used in the forums has to be the same as the contents we publish. The usage of other languages, with the exception of some words, is forbidden. Messages that are off-topic will not be published.
  10. Making repetitive posts disrupts the flow of discussions and will not be tolerated.
  11. Adding images or any other type of file to comments is forbidden. Including hyperlinks to other websites is allowed, as long as they comply with netiquette. Radio Canada International  is in no way responsible for the content of such sites, however.
  12. Copying and pasting text written by someone else, even if you credit the author, is unacceptable if that text makes up the majority of your comment.
  13. Posting any type of advertising or call to action, in any form, to Radio Canada International  forums is prohibited.
