Knee Preservation with Cartilage Repair: A Pathway to Mobility and Longevity

The knee joint plays a crucial role in our daily lives, facilitating movement, stability, and weight-bearing activities. However, the integrity of the knee joint can be compromised by various factors, including injury, overuse, and degenerative conditions. Damage to the knee’s cartilage, in particular, can have significant adverse implications for joint health and function, often leading to pain, stiffness, and impaired mobility. In recent years, there has been growing interest in knee preservation strategies aimed at repairing damaged cartilage and restoring joint function.

What Is Knee Cartilage Repair

Knee cartilage repair is a treatment that helps restore damaged cartilage in your knee. Cartilage is the smooth tissue that cushions your bones and lets you move without pain. If you’ve injured your knee through sports, an accident, or wear and tear, you might feel pain, swelling, or stiffness. Cartilage repair can relieve your pain, improve your knee’s function, and slow down further damage, helping you get back to your daily activities.

What Are the Causes of Knee Cartilage Injury

Knee cartilage can get damaged for several reasons. You might experience injury or wear and tear from:

Sports or high-impact activities: Sudden twists, jumps, or collisions can tear cartilage.
Accidents or falls: Direct trauma to your knee can damage the cartilage.
Ageing and natural wear: Over time, cartilage thins, making your knee more prone to injury.
Repetitive strain: Repeated bending, kneeling, or heavy lifting can stress the cartilage.
Previous knee injuries: Old injuries or surgeries can weaken cartilage and make it more vulnerable.

When Is Cartilage Repair Surgery Recommended

You might need cartilage repair surgery if your knee injury is affecting your daily life or mobility. Surgery is usually considered when:

You have persistent pain or swelling that doesn’t improve with non-surgical treatments.
Your cartilage damage is significant or deep, affecting joint function.
You experience locking or catching in the knee due to torn cartilage.
You have early signs of osteoarthritis caused by cartilage loss.
Non-invasive treatments like physiotherapy, medications, or injections haven’t worked.

What are the Consequences of Knee Cartilage Damage?

The knee cartilage is vulnerable to damage from acute injuries, such as sports-related trauma or falls, as well as chronic conditions like osteoarthritis. When cartilage is compromised, the protective layer between the bones wears away, leading to friction, inflammation, and ultimately, joint degeneration. In addition to pain and stiffness, cartilage damage can impair joint stability, increase the risk of further injury, and accelerate the progression of osteoarthritis. If left untreated, severe cartilage damage may necessitate invasive interventions such as joint replacement surgery, with implications for long-term mobility and function.

The knee cartilage is a crucial tissue that facilitates movement.

How Can Cartilage Repair Techniques Benefit Knee Preservation Efforts?

Cartilage repair plays a vital role in knee preservation, offering hope for individuals with cartilage damage to maintain mobility, function, and quality of life. Recognising the importance of preserving the knee joint and avoiding or delaying the need for more invasive procedures, orthopaedic specialists have explored various techniques for cartilage repair without requiring any modifications to its surrounding tissues. These approaches aim to restore the structural integrity of the cartilage, alleviate symptoms, and promote long-term joint health.

Types of Knee Cartilage Repair Surgery

When it comes to surgical repair of knee cartilage, several techniques are commonly used, depending on the size and location of the injury:

Microfracture: Small holes are created in the bone beneath the damaged cartilage, enabling blood and stem cells to access the injured area and promote the formation of new cartilage-like tissue to stimulate new cartilage growth. This procedure is often performed arthroscopically and is suitable for smaller cartilage defects.
Autologous Chondrocyte Implantation (ACI): Healthy cartilage cells are harvested from the patient’s own body, cultured in a laboratory, and implanted into the damaged area of the knee joint to promote cartilage regeneration. ACI is frequently recommended for younger patients with minimal cartilage damage.
Osteochondral Autograft Transplantation (OAT): Healthy cartilage and bone tissue is transferred from a non-weight-bearing part of your knee to repair the damaged area, restoring the joint’s structural integrity and function.
Cartilage Regeneration: Minimally invasive procedures that harness the body’s cell to replace damaged cartilage naturally, suitable for individuals with minimal cartilage damage.

What Happens During the Cartilage Repair Surgery?

Preparation: The patient is prepped for surgery, which includes anesthesia administration and positioning on the operating table.
Accessing the Joint: An incision is made to access the affected joint, often using arthroscopic techniques for minimally invasive procedures.
Cartilage Repair: The damaged cartilage is treated using various techniques like microfracture, mosaicplasty, or autologous chondrocyte implantation (ACI) to promote healing and regeneration.
Closure: After repairing the cartilage, the surgical site is carefully closed and dressed to prevent infection and promote healing.

What Should You Expect During the Postoperative Recovery Process?

Patients undergoing cartilage repair procedures should have realistic expectations regarding pain relief, functional improvement, and return to activity. The procedure’s success is contingent on various factors, including the size and location of the cartilage defect, the patient’s age, overall health, and adherence to postoperative rehabilitation. Long-term success depends on various factors such as patient compliance with postoperative rehabilitation, maintenance of a healthy lifestyle, and avoidance of activities that place undue stress on the repaired joint.

Pain Management: Pain and swelling are common in the early stages of recovery. Pain medications and anti-inflammatory drugs will be prescribed to manage discomfort.
Physical Therapy: Physical therapy focuses on restoring range of motion, strength, and stability in the affected joint. Therapeutic exercises, manual therapy techniques, and modalities such as ultrasound or electrical stimulation may be incorporated into the rehabilitation programme.

Non-Surgical Cartilage Injury Treatment

If your cartilage damage is mild or you want to avoid surgery, several non-surgical options can help reduce pain, improve knee function, and slow further damage:

Physical Therapy: Targeted exercises strengthen the muscles around your knee, improve stability, and reduce stress on the cartilage.
Medications: Anti-inflammatory or pain-relief medications can help manage swelling and discomfort.
Injections: Treatments like hyaluronic acid or platelet-rich plasma (PRP) injections can support cartilage health and relieve pain.
Lifestyle Modifications: Reducing high-impact activities, maintaining a healthy weight, and using supportive footwear can protect your knee and prevent worsening of the injury.
Assistive Devices: Braces or orthotics can reduce load on your knee, giving damaged cartilage a chance to recover.
