Overview and Definition
Cartilage Restoration is a specialized field of orthopaedic medicine focused on repairing, regenerating, or replacing damaged hyaline cartilage in a joint. Unlike bone or skin, articular cartilage does not have its own blood supply, which means it cannot heal itself once it is injured. When the smooth, slippery surface that cushions your joints wears away or is damaged by trauma, it can lead to chronic pain and the early onset of osteoarthritis. Restoration aims to restore the biological integrity of the joint using living tissue.
The primary goal of Articular Cartilage Restoration is to replace a focal defect with new, healthy tissue that mimics the original structure. This approach is fundamentally different from a joint replacement; while a replacement uses artificial materials like metal and plastic, restoration utilizes biological “fixes.” This is particularly beneficial for younger, active patients who want to preserve their natural joint and return to high-impact activities that a prosthetic might not support.
Injury and Causes
The need for Cartilage Restoration often stems from an acute injury, such as a sudden twist or a direct impact on the joint. When a person suffers a ligament tear (like an ACL injury) or a patellar dislocation, the bones can knock together with enough force to shear off a piece of the cartilage. Because the tissue lacks blood flow, this injury remains open and can worsen over time as the edges of the defect begin to fray.
In addition to sudden trauma, the need for Articular Cartilage Restoration can be caused by chronic mechanical stress. If a patient’s joints are not perfectly aligned—such as being “bow-legged” or “knock-kneed”—it can put excessive pressure on one specific area. Over years, this uneven loading “grinds down” the cartilage, leading to a defect that eventually requires surgical intervention to prevent total joint failure.
Diagnosis and Imaging
Because cartilage damage does not show up on standard X-rays, diagnosing the need for Cartilage Restoration requires high-level clinical expertise. A surgeon will evaluate your joint for localized pain, recurrent swelling (effusion), and mechanical symptoms like clicking or “giving way” that suggest a disruption in the smooth gliding surface of the joint.
High-resolution MRI is the essential tool for planning Articular Cartilage Restoration. Standard MRIs may miss small lesions, so at Liv Hospital, we use specialized sequences that specifically highlight cartilage thickness and quality. These images allow the surgeon to measure the exact size and depth of the “pothole,” which is critical for choosing the right biological repair technique.
Treatment and Recovery
During Knee Articular Cartilage Repair, several biological methods can be used. Microfracture involves creating tiny holes in the bone to allow stem cells to form new tissue. Osteochondral transplantation (OATS) moves a plug of healthy bone and cartilage into the defect. Cell-based therapies, such as ACI, involve harvesting a patient’s own cells and replanting them into the joint.
The recovery from Articular Cartilage Restoration is longer than a standard arthroscopy because we must wait for the “living” tissue to mature. For the first 6 weeks, patients are typically non-weight bearing to protect the graft. Full maturation of the new cartilage can take 9 to 12 months, requiring a disciplined, phased approach to rehabilitation to ensure the new tissue bonds correctly to the bone.
Rehabilitation Tips
The most critical part of Cartilage Restoration happens after the surgery. Because the new cartilage is initially soft, it must be protected from shearing forces while receiving enough “gentle” movement to stay healthy. Using a Continuous Passive Motion (CPM) machine is often recommended to help the new cells organize and receive nutrients without the stress of weight-bearing.
To ensure the longevity of your Knee Articular Cartilage Repair, it is essential to strengthen the surrounding muscles without high-impact stress. Focus on non-impact exercises like swimming or stationary cycling once cleared by your surgeon. Maintaining a healthy weight is also vital, as it reduces the compressive load on the newly restored articular surface.

Restoration involves repairing the damaged tissue using biological methods to stimulate new growth or transplanting healthy tissue. Replacement involves removing the damaged joint surfaces entirely and substituting them with artificial materials like metal and plastic.
No, it is generally reserved for patients with isolated, focal cartilage defects rather than widespread arthritis. The surrounding cartilage must be healthy, and the patient must be able to commit to a rigorous rehabilitation program.
Generally, articular cartilage does not grow back on its own because it lacks a blood supply. Without blood, the body cannot deliver the necessary cells and growth factors to the injury site to initiate the healing process naturally.
The knee is the most common joint treated due to the frequency of injuries and accessibility. However, techniques are also applied to the ankle (talus), shoulder (humeral head), and occasionally the hip, depending on the specific defect.
The longevity of the repair varies based on the technique used, the size of the defect, and the patient’s lifestyle. Many procedures provide relief and function for 10 to 15 years or more, effectively bridging the gap until a replacement might be needed later in life.
