Cartilage Repair

Cartilage Repair In Singapore

Cartilage is essentially the protective layer of all joints. It helps to cushion and lubricate the joints- where two bones meet.

Cartilage damage can be seen as an ulcer (hole) or crater on the otherwise smooth surface of the joint. If left untreated, the joint can become stiff, swollen, and painful. It may even progress to a stage requiring total joint replacement with metal and plastic components.

At our clinic, we offer a range of advanced treatments for cartilage repair, including:

  • Cartilage regeneration

    is a procedure that attempts to restore damaged cartilage by harnessing the body’s cells to regrow or replace lost cartilage.

    Most of these treatments can be done by arthroscopy (more commonly known as keyhole surgery), providing benefits of less pain, less bleeding, and faster recovery. However, some injuries will still require a traditional open incision technique with a bigger cut to expose the cartilage damage.

  • Cartilage transplantation

    involves transplanting healthy cartilage from a donor or another part of the patient’s body to replace damaged cartilage.

  • Microfracture

    is a popular surgical technique for treating areas of damaged cartilage. It is suitable for patients with a small area of damaged cartilage in their joints. The procedure is often performed inside the knee joint but may also be used to treat other joints, such as the hip, ankle, and shoulder.

    For injuries smaller than 2cm2, microfracture is the recommended procedure. It involves puncturing small holes in the subchondral bone, a stem cell reservoir.

    The small holes act as channels for the bone marrow cells to surface and fill the area of damaged cartilage. The cells gather in a clot which transforms into fibrocartilage. Fibrocartilage is a tough, dense and elastic material that helps fill in the torn part of the cartilage, hence repairing the lesion.

  • Autologous chondrocyte implantation (ACI),

    ACI is often recommended for younger patients with single defects larger than 2cm2. This is a 2-step procedure that takes several weeks to complete. The first procedure involves extracting healthy cartilage cells from a non-weight-bearing area of the knee through minimally invasive surgery. The cells are then cloned and grown in the laboratory for 6 – 8 weeks. After that, a surgical procedure is done to implant the newly grown cells into the damaged area.;

    This is a 2-step procedure that repairs the articular cartilage damage by using the patient’s own cultured cartilage cells. The first step is similar to that in ACI, where healthy cartilage cells are extracted from a non-weight-bearing area of the knee. The cells are then cultivated on a membrane. Several weeks later, the membrane is placed into the defect. This helps the cartilage regenerate.

    Articular cartilage is the smooth, white tissue covering the ends of bones, which come together to form joints. The presence of cartilage in the joints helps in movement and allows bones to glide over each other with little friction. However, daily wear and tear or an injury may damage the articular cartilage.

  • Osteochondral autograft transplantation

    In this 1-step procedure, the surgeon harvests a ‘plug’ of healthy tissue and bone from an unaffected, non-weight-bearing area of the patient’s own joint. Then, the new graft is transferred to replace the damaged area. When multiple ‘plugs’ are used, the result is like a mosaic pattern, hence the term mosaicplasty.

Our orthopaedic surgeons are experts in these treatments and have helped many patients recover from cartilage damage and return to normal activities.

In addition to our expertise in cartilage repair, we also provide comprehensive orthopaedic care for a wide range of conditions, including:

  • Joint pain and arthritis

Cartilage Repair Treatment

Anterior Knee Pain

Anterior knee pain is a common condition that affects many people, especially athletes and those who engage in physical activity. It is characterized by pain and discomfort in the front of the knee, often around the kneecap.

There are many potential causes of anterior knee pain, including overuse, improper form or technique during physical activity, and underlying structural issues with the knee joint or surrounding tissues. Some people may also experience anterior knee pain as a result of cartilage damage.

At our clinic, we have extensive experience diagnosing and treating anterior knee pain. We use a variety of diagnostic techniques, including imaging tests such as X-rays and MRIs, to identify the underlying cause of the pain. Then, depending on the cause, we may recommend a range of treatments, including physiotherapy, medication, or surgery.

Our healthcare professionals work closely with each patient to develop a personalized treatment plan that addresses their individual needs and goals. We are committed to helping our patients find relief from their pain and return to their active, healthy lifestyles as quickly and safely as possible.


Symptoms of cartilage damage can include joint pain, stiffness, swelling, and a limited range of motion. If you are experiencing these symptoms, we recommend scheduling a consultation with one of our orthopaedic surgeons.

We offer a range of advanced treatments for cartilage repair, including cartilage regeneration, and cartilage transplantation.

During your consultation, one of our orthopaedic surgeons will evaluate your symptoms, review your medical history, and perform a physical exam. They may also order imaging tests, such as X-rays or MRIs, to help make an accurate diagnosis.

Recovery times can vary depending on the type of treatment you receive and the extent of your injury. Our healthcare professionals will provide you with detailed instructions on how to care for your injury and what to expect during your recovery. We may also recommend physiotherapy or other forms of rehabilitation to help you regain strength and mobility in the affected joint.

We accept a wide range of insurance plans, including those from major providers such as AIA, AXA, GE, and Prudential. Please get in touch with us for more information about your specific insurance coverage.
