Can You 3D Print Knee Cartilage?

By  aenriquez  published  January 8, 2018

Young or old, you’ve probably felt a nagging pain in your knee at some point.  In fact, some studies suggest that knee pain has increased up to 65% in the over the past few decades. But for some that pain becomes constant and unbearable. That can be for a number of reasons including:

Printing 3D Cartilage for Knee Surgeries

  • Osteoarthritis (often referred to as degenerative or “wear and tear” arthritis
  • Damage to the meniscus or cartilage (this can also be caused by osteoarthritis)
  • Gout
  • Tendonitis
  • Bursitis
  • Torn ligament or tendon

 

For many of these conditions, there are clear treatment plans that pave a way to recovery. However, cartilage damage (the regions of cartilage in the knee are known as menisci) has previously been tricky to treat. But now revolutionary technologies and surgeries could provide hope to those suffering in silence.

 

What do the menisci do?

 

The menisci sit on the bones of your knee and act as cushions. They absorb shocks and make sure the bones of your knee don’t bump and rub against each other. However, unlike most tissues they don’t have a blood supply and as such can’t get the nutrients they need to repair themselves. Damage often occurs in young people with sports injuries. You may hear doctors talk of the “unhappy triad” where athletes tear their ACL, MCL and damage their medial meniscus. This is what happened to Judy Hobson who talked to the DailyMail about her road to recovery

 

“I had to give up sport altogether. I could barely walk a couple of hundred yards and was starting to limp. I was miserable because it was such a huge part of my life. I even thought about having my leg amputated and being fitted with an artificial limb”

 

A 3D printing breakthrough

 

New hope could be on the horizon as researchers at the University of Alberta are working on 3D printing knee cartilage needed for transplant surgery. They have been able to print a 3D leaf made of natural proteins. One of the engineers, Stella Matthews, said

 

“It is the first step towards tissue engineering,”

 

Next, they will try to print cartilage shaped for the individual that surgeons can transplant into the patient’s knee.

 

What can be done at the moment?

 

Whilst these results are highly exciting, they aren’t available for the patient right now. However, patients can still have a meniscus replacement surgery. This is what Judy Hobson had done. Again talking to the Daily Mail she said

 

“After nine months, I could walk more than a mile pain-free – now it’s five or six miles and I’ve also started to play a little volleyball again. I’m so grateful to the person who donated the meniscus.”

 

Specialist clinics across the United States offer the procedure. Ricky Valadez, who had the procedure and talked to Fox32 about it said

 

“The best thing, in the long run, is I’m going to be able to have the opportunity to do whatever I want and not be held back,”.

Common Workplace Injuries

By  admin2  published  October 23, 2014

Depending on what type of industry you’re working in, you may be vulnerable to different types of workplace injuries. Some risks are more common than others, though. In some cases, these injuries lead to patients missing work, or cause varying levels of chronic disability. Along with knowing what to watch out for, knowing what kind of treatment to seek out will limit problems at work and with your health.

Backs:Back pain is the most common type of workplace injury, typically from strain and overuse. Improper lifting technique is a known problem, although bad posture in sedentary workers also leads to back injury. These can range from disc herniation to vertebrae or cervical fractures, and strains of either the lower or upper back.

Supportive back braces may help protect from acute overexertion. Rest followed by gradual knee surgeons phoenix az	introduction of physical therapy and behavior or posture adaptation going forward is a preferred treatment.

Shoulders:Shoulder injuries can sometimes result from falls, including in patients who catch themselves and hang by their arms—in falling off the edge of a roof or an open walkway, for example. This can cause labral tears in the cartilage surrounding the joint socket. Other types of sprains, rotator cuff injuries, or pinched nerves can all result from strain or movement when the arm is being held overhead.

In some cases, breaking a fall with your arm can cause fracturing in the shoulder joint. This is indicated by more severe grinding and swelling or deformity. Most types of shoulder fractures will be treated with immobilization, although surgery to install plates or screws will be necessary if fragments have shifted out of place. Severe shoulder separations, from a fall or from lifting, may also require surgery for ligament repair.

Other arm injuries: While falls can also lead to injured elbows and wrists or broken arms, carpal tunnel syndrome is a common injury for workers who spend a lot of time in front of computers. As it becomes more severe, bracing and behavioral adaptation will be required for pain relief and healing.

Knees and legs:Damage to ligaments often comes from acute injuries. The ACL can be strained or torn in landing from a jump or fall, or from a sudden change in direction if you need to dodge something, while other ligaments can be injured from an impact against the knee. Sudden stops or pivots also tear other parts of the knee, such as the meniscus. Other injuries, particularly tendinitis, come from overuse.

While severe knee injuries may need surgical treatment, some can be improved with shorter-term bracing and physical therapy that strengthens the surrounding muscle.

Consulting a doctor as soon as possible after your injury will help you recover more quickly and more completely, and will also help support your worker’s comp claim. An orthopedic surgeon at FXRX can run tests and determine what kind of treatment you might need. They can also help you defend any need to take time of work for recovery.
