Chondral Dart

<p>El Chondral Dart de PLLA bioabsorbible tiene un diseño original con doble púa invertida que facilita la compresión y fijación superior de los desgarros del colgajo osteocondral de hasta 2 cm de diámetro. El dardo condral de 18 mm de largo y 1,3 mm de diámetro brinda una fijación segura debajo de la superficie del cartílago hialino para eliminar el contacto con superficies articulantes sensibles.</p>

Osteochondral Flap Repair System With Chondral Dart™ Implant

Today we'll be discussing control darts and its utilization in control flap fixation. On our table, we see a single shot cannula with its sheath, which the cannula allows for easier utilization of this system in the arthroscopic setting. To the right, we see a inserter followed by a single shot drill. In the middle, we have our two and four hole guide sleeves, followed by the drill pins, and then we see our two blunt pins, which allow to hold the guide sleeve in position. As you remove the drills and allow for insertion of your darts. Finally, we see our control dart inside its implant case, so we've removed the dart for better visualization. Here we see the dart, which is a bioabsorbable PLA double reversed barbed to facilitate fixation and compression of the chondral flap. The control dart comes in an 18 millimeter length and is 1.3mm in diameter. It allows for secure fixation under the highland cartilage surface to eliminate contact with the articulating joint surface. So let's move over to the knee right now and show what the lesion looks like and how we can utilize the condo dart in the knee. Arthroscopically we're panning over to the lateral femoral condyle where we see a lateral femoral condyle, full thickness chondral defect over here. And as we kind of lift it up, we see the full thickness nature of that defect with barely any bony attachment back there. And we want to really be careful here to allow that hinge to remain intact, not to displace that chondral defect as you want to sit it right back into its home for fixation later on. So right now we are showing the zebra probe, which allows for improved measurement of a defect. You can move this knob back and forth to allow to improve your measurement intra articularly. So now we're bringing our zebra probe into the knee here to allow us to get a better measurement of the width and length of the Chondral defect. As we bring the probe across here, we can see here that the length is approximately ten millimeters. And then as we open up the jaws of the probe here, we can get a measurement right there of approximately 9 to 10mm. Chondral darts can be utilized in condl defects up to 20mm. So here we have the two hole drill guide to allow for fixation of the darts. Our plan here is to use three darts two at the edges and one centrally. It is important to have the edges to sit flush to prevent any catching during movement of the knee from flexion to extension. So first we're going to be placing the first drill into the two hole drill guide. There is a positive stop of this drill. And using the sheath and inserter to drill our next conical dart fixation hole. This allows for the dart to be placed immediately followed this drilling. So now we're going to bring the dart into view here with the rubber band still attached, attach it to the end of the inserter device, and then push the thumb pedal down to deliver the dart. Next will be the inserter, which will then place the dart fully into its position. Until the black inserter is flush with the sheath. All right, so now we're taking out the drill followed by placement of the inserter To hold the position of our two hole drill guide. And now we're going to place the control dart with the sheath. Now the second control dart is going to be placed by pushing your thumb paddle down. Followed by utilization of the inserter to plunge the dart into its position. Now we'll be placing a third dart to improve the compression of the control flap at the free edge. So it's critical to stay steady with the drill guide to prevent any sort of eccentric drilling as you go through, as well as eccentric placement of the dart. So now we're replacing the dart on the edge of the inserter and then pushing it through through the thumb pad, and then using the mallet to further deliver the dart into its position. I recommend a minimum of three candidates to secure the fragments that are greater than one centimetre in diameter. Additionally, for smaller lesions, a single shot kit can be used, or a multi-shot kit can be used with a two hole guide sleeve as shown today. Additionally, auto cart is a great option for certain lesions that cannot be fixed by taking down the control flap using a shaver and a graphnet, and re implanting the autologous chondrocytes over the defect site. At this point, one can consider utilizing the Apollo Small Joint 50 to achieve better contouring of the chondral flap edges. And so the final step in this case will be to bring the knee through full range of motion and confirm that there is no flap edges causing any sort of problems as you bring it through full articulation there.
