Advanced treatments for OCDs

In this third video, Dr. Grant Garcia focuses on advanced interventions for Osteochondritis Dissecans (OCDs) when standard treatments like drilling or screw fixation fail, or when the bone fragment completely separates.

Here is a summary of the description and key points discussed in the video:

• Saving Floating Fragments: When an OCD fragment completely breaks off and floats inside the knee, it is an emergency. However, Dr. Garcia explains that if the tissue quality is good, it is still possible to salvage and reattach it using the screw technique—even in patients up into their 30s with closed growth plates. Success rates for saving these pieces sit around 70% to 80%, depending heavily on how much healthy bone is still attached to the cartilage piece.
• What Happens if It Fails to Heal? If a piece cannot be saved or fails to heal properly, it must be removed. This leaves a significant hole or defect in the joint that requires replacing both the underlying bone and the surface cartilage.
• Advanced Reconstruction Options:
  • Minor Defects: Smaller holes can sometimes be treated using a "biocartilage" technique, which combines a microfracture procedure with bone grafting and juvenile cartilage.
  • Medium Defects: A "sandwich technique" using MACI (Autologous Cultured Chondrocytes on Porcine Collagen Membrane) can be deployed to rebuild the structural layers.
• The Gold Standard (Cartilage Transplant): For patients where growth plates have closed (especially those in the 25 to 30+ age range), an osteochondral allograft (cartilage transplant) is the premier treatment. This is one of the most common reasons Dr. Garcia performs transplants. It boasts an 85% success rate lasting 10 to 15 years and offers an excellent rate of return to sports, provided it is caught before secondary damage occurs to the meniscus or other structures.
