Cartilage Transplantation

Cartilage transplantation is an advanced surgical procedure used to repair significant cartilage damage in joints, such as the knee. In this treatment, healthy cartilage tissue—harvested either from the patient’s own body or from a donor—is transplanted to the damaged area to reconstruct the joint surface. The primary goals are to reduce pain, restore joint function, and prevent the progression of osteoarthritis.

Who is at Risk for Cartilage Damage?

Traumas related to sports injuries
Falls or sudden impacts on the knee
Associated injuries such as anterior cruciate ligament (ACL) tears
Congenital weakness of the cartilage structure
Secondary cartilage loss following meniscus or ligament surgery
Excessive stress on the joints in individuals with high body weight

Who is a Candidate for Cartilage Transplantation?

Individuals who are generally considered suitable for cartilage transplantation include those who:

Have localized cartilage loss in joints such as the knee or ankle
Are under 50 years old and maintain an active lifestyle
Have intact ligaments that stabilize the joint
Do not have significant joint space narrowing
Are in the early stages of osteoarthritis or have not yet developed it
Have not benefited from conservative treatments, such as medication, physical therapy, or injections

How is Cartilage Transplantation Performed

Cartilage transplantation can be performed using several techniques. The method is determined by an orthopedic specialist based on the size and location of the damage:

1. Mosaicplasty (Osteochondral Graft Transfer):

Cylindrical plugs of healthy cartilage and bone are taken from a non-weight-bearing area of the patient’s knee and transplanted into the damaged region. This technique is suitable for small, localized defects.

2. Allograft Transplantation (Donor Cartilage Transplant)

Cartilage tissue of appropriate size and structure, obtained from a donor, is placed into the patient’s damaged joint area. This approach is preferred for larger lesions.

3. ACI (Autologous Chondrocyte Implantation)

The patient’s own cartilage cells are harvested and cultured in a laboratory. In a second procedure, these cells are implanted into the damaged area. This method is used for extensive or deep cartilage defects.

Surgical procedures can be performed arthroscopically (minimally invasive) or via open surgery. The choice of technique affects both the duration of the operation and the recovery process.

Postoperative Recovery Process

Recovery following cartilage transplantation requires careful monitoring and a structured rehabilitation program:

First 4–6 weeks: Non-weight-bearing walking using crutches
From week 6 onwards: Controlled exercise program begins
After 3 months: Strengthening exercises for muscles
6–12 months: Return to sports and active lifestyle (depending on the surgical technique)

Physical therapy is a crucial part of the recovery process and has a direct impact on the success of the procedure.

What Are the Benefits of Cartilage Transplantation?

Reduces joint pain
Preserves cartilage structure and prevents progressive osteoarthritis
Delays or eliminates the need for joint replacement at a younger age
Maintains the natural structure of the joint
Improves quality of life and supports an active lifestyle

What Happens If Cartilage Damage Is Left Untreated?

Untreated cartilage injuries can lead to:

Wear and tear on the joint surface
Development of osteoarthritis
Pain and limited range of motion
The potential need for joint replacement surgery

Early intervention is especially important for young and active individuals to prevent long-term joint damage.

Conclusion
Cartilage transplantation is an advanced surgical option that provides effective, long-term results for young and active individuals with significant cartilage loss. If you experience persistent pain, locking, or restricted movement in your knee or other joints, consult an orthopedic specialist to determine whether you are a suitable candidate for cartilage transplantation. Early diagnosis and proper treatment are key to maintaining joint health.

Frequently Asked Questions (FAQ) – Cartilage Transplantation

Does cartilage repair itself?
Cartilage tissue has very limited self-healing capacity because it lacks blood vessels. In cases of significant damage, surgical intervention is necessary.
Is cartilage transplantation permanent?
With proper patient selection, surgical technique, and adherence to the rehabilitation program, cartilage transplantation can provide long-lasting and successful results.
Is transplantation necessary for every cartilage injury?
No. Small or superficial injuries may be treated with injection therapies, such as PRP or stem cells, or procedures like microfracture. Transplantation is considered for more advanced cases.
