Knee injury frequently involves not only damage to ligaments, patella, and meniscus. Knee trauma also involves osteochondral fractures. What is an osteochondral fracture? How to treat osteochondral fractures, especially in athletes? Osteochondral fractures are fractures, which remove part of bone and cartilage from the loaded area of the joint. We see that after a traumatic patellar dislocation. So it is called flake fractures. So the etiology of that Osteochondral fracture is an acute high-energy trauma, which removed a piece of cartilage in combination with a subchondral bone plate. So we see osteochondral fractures many times in athletes. We also see some flake fractures after traumatic tear of the knee ligaments caused by ligament injuries. So this is also one of the factors where we can see osteochondral fractures. Sometimes we see osteochondral fractures also in the back of the tibia bone head after an ACL tear. So, these are many locations of osteochondral fractures. The good thing is the osteochondral fractures mostly heal very actively compared to a chronic knee problem. Suppose we can re-fix that cartilage fragment into the right place. If we can fix osteochondral fractures in a stable way, you have the best situation. Then Osteochondral fracture heals mostly properly. But in some cases, you have to use screws to fix osteochondral fractures. You have to remove the screws later on. So, for that reason, after osteochondral fractures, a patient also needs time for rehabilitation. The osteochondral fractures are quite different from other osteochondral defects. So, we also see osteochondral defects in the field of our back. We see that in the OCD. So we see many reasons, but the pathology in the Osteochondritis dissecans (OCD), for example. Osteochondritis dissecans (OCD) is a disease of a subchondral bone. We have to address therapeutically that with cancellous bone implantation to enhance the biology under subchondral bone properly. Because this is the reason why osteochondral disease is starting. To stop and heal Osteochondritis dissecans (OCD), you have to address the pathology in the subchondral bone. In the case of osteochondral fracture, the pathology is not in the subchondral bone. The problem is the fracture itself is easily fixed. Osteochondral fracture treatment gives a good outcome, mostly.
