Osteochondritis Dissecans Treatment Options

Evaluation begins with a detailed history and physical examination. Dr. José Vega will ask about your pain pattern, sports participation, prior injuries, and any episodes of catching or locking. On exam, there may be tenderness over the affected femoral condyle, swelling, or limited range of motion.

X-rays are usually the first imaging test and can show characteristic changes in the bone, including a small lesion, sclerosis, or separation of a fragment. MRI is often used to assess the size and stability of the lesion, the quality of the overlying cartilage, and whether fluid has tracked behind the fragment—an important sign of fragment instability. In some cases, the final assessment of stability is made arthroscopically at the time of surgery.

One of the most important distinctions in OCD is whether the patient’s growth plates are still open (juvenile OCD) or closed (adult OCD). Juvenile lesions have a better potential to heal with nonsurgical treatment, while adult lesions are more likely to require surgery, especially if unstable.

Yes—especially in younger patients with stable lesions and open growth plates. In these cases, the blood supply to the area may recover, and the bone and cartilage can remodel if the lesion is protected from excessive stress.

Nonsurgical treatment often includes:

• Activity modification: Avoiding impact sports, running, and jumping for a period of time.
• Bracing or protected weight-bearing: Using crutches or a brace to reduce load through the lesion.
• Physical therapy: Focusing on maintaining range of motion, hip and core strength, and safe, low-impact conditioning.

Healing is monitored over time with repeat X-rays and, in some cases, follow-up MRI. It is common for this process to take several months, and return to sports is generally allowed only after imaging shows healing and symptoms have resolved. In well-selected juvenile patients, a large percentage of stable lesions can heal nonoperatively.

However, if pain persists, the lesion appears unstable, or the fragment begins to separate, surgery is usually recommended to stabilize or reconstruct the area and protect the joint surface.

Surgical treatment is tailored to the size, location, and stability of the lesion, as well as the age and activity level of the patient. The overall goals are to restore a stable, smooth joint surface, preserve as much native cartilage as possible, and prevent early arthritis.

Drilling (Transarticular or Retroarticular) for Stable Lesions

For smaller, stable OCD lesions that have not responded to nonsurgical care—particularly in younger patients—drilling can be used to stimulate healing. Tiny channels are created through the bone toward the lesion to allow new blood vessels to grow in and re-vascularize the area. This can be done either through the joint surface (transarticular) or from the back side of the bone (retroarticular), depending on surgeon preference and lesion characteristics.

After drilling, patients typically follow a period of protected weight-bearing and activity restriction while the lesion heals.

Fixation of Unstable or Detached Fragments

When the OCD fragment is partially detached but still has healthy cartilage, internal fixation is often the best option. During arthroscopy or mini-open surgery, the fragment is repositioned and secured using screws, bioabsorbable pins, or specialized implants designed for osteochondral fixation.

Fixation allows the body to heal the bone beneath the cartilage while preserving the patient’s native articular surface. This approach is particularly appealing in adolescents and young adults with good-quality cartilage and a sizeable, reconstructable fragment. Postoperatively, patients typically go through a period of limited weight-bearing and gradual rehabilitation.

Osteochondral Grafting for Non-reconstructable Lesions

If the fragment is non-viable, fragmented, or missing, osteochondral grafting techniques can be used to restore the defect:

• Osteochondral Autograft Transfer (OATS/Mosaicplasty): Small plugs of cartilage and bone are harvested from a non–weightbearing area of the knee and transferred into the OCD defect. This provides immediate restoration of hyaline cartilage and underlying bone.
• Osteochondral Allograft Transplantation (OCA): For larger lesions, a size-matched donor graft is shaped to fit the defect and press-fit into place. This is especially helpful in large OCD lesions of the femoral condyles or trochlea, or when there has been previous failed surgery.

These procedures are often used in older adolescents or adults where the lesion is too large or unstable to be treated with drilling or simple fixation, and when joint preservation is a priority.

Cartilage Restoration and Combined Procedures

In some cases, especially when there is associated cartilage damage beyond the OCD fragment, cartilage restoration techniques such as matrix-assisted autologous chondrocyte implantation (MACI) or scaffold-based procedures may be considered. Often, these are combined with osteotomy (realignment) if malalignment is present, to reduce stress on the affected area. Addressing alignment, ligament stability, and meniscal status is critical to give the repaired area the best possible chance to succeed.

Recovery from OCD surgery varies depending on the procedure and lesion size, but most patients go through:

• A period of protected weight-bearing (often 4–8 weeks)
• Gradual increase in range of motion
• Progressive strengthening of the quadriceps, hamstrings, and hip musculature
• A structured return-to-sport program

With appropriate treatment and rehabilitation, many patients—especially those treated before advanced cartilage wear develops—can return to sports and maintain good long-term knee function. However, untreated or unsuccessfully treated OCD can lead to persistent pain, loose bodies, and early osteoarthritis.
