What is Cartilage Transplantation?

Cartilage (osteochondral allograft) transplantation involves replacing damaged cartilage and the underlying bone in joints like the knee with healthy tissue from a donor. This method is used when patients have severe cartilage damage that cannot be repaired with other treatments, such as microfracture or autologous chondrocyte implantation. The donor tissue includes both the cartilage and bone, which makes it particularly suitable for large, deep defects where other methods fail to provide durable results.

Cartilage has a limited capacity to repair itself, which makes surgical intervention necessary in cases of severe damage. Cartilage transplantation aims to reduce pain, improve mobility, and preserve knee joint health in the long term.

Who is a Candidate for Cartilage Transplantation?

Cartilage transplantation is an effective option, especially for younger and active individuals with specific cartilage lesions. Candidates for this procedure typically include:

– Patients with Severe Cartilage Damage: Individuals under 40 with localized cartilage damage in the knee, often caused by injury or trauma, are ideal candidates.

– Failed Previous Treatments: When conservative treatments or prior surgeries have failed for the cartilage defect, cartilage transplantation may be considered.

However, it is generally not recommended for older patients or those with advanced osteoarthritis. In such cases, other surgical options may be explored like knee arthroplasty

In suitable candidates, cartilage transplantation can significantly improve joint health, reduce pain, and enhance daily activities. If you are experiencing cartilage damage, consult with our specialists to explore the best treatment options for your condition.

Osteochondral allografts are advantageous because they provide a durable hyaline cartilage surface, which is stronger and more similar to native cartilage compared to the fibrocartilage generated by other techniques. The goal is to delay or prevent the need for more invasive procedures like total knee replacement, while also improving joint function and reducing pain.

The success of this procedure depends on careful planning, proper sizing of the graft, and precise surgical technique. Long-term results are promising, especially in patients with isolated cartilage damage and good surrounding joint health. This treatment has been successfully performed worldwide and has shown excellent outcomes in preserving joint function over time.
