Cartilage Repair


Cartilage Repair: Meniscal Repair and Replacement

The cartilage helps the knee move smoothly and absorb shock during daily activity. When this tissue becomes damaged, even simple movements like walking or standing can feel uncomfortable. Without early treatment, cartilage injuries may progress and affect long-term joint health.

How Cartilage Injuries Happen

Injuries often occur during sports that involve twisting, pivoting, or sudden impact. Accidents and falls can also damage the joint surface directly. Over time, repeated strain on the knee may weaken cartilage and make it easier to tear. In some patients, untreated ligament injuries place extra stress on the joint. This added load increases the risk of further cartilage damage.

What Changes Inside the Knee?

As it wears down or tears, the joint loses its natural cushioning. With less protection, bones may rub against each other during movement. Pain, swelling, and stiffness often follow, especially during activity. Reduced flexibility can develop as inflammation increases. Walking, bending, or bearing weight may then become more difficult.

Why Early Treatment Matters

Early assessment helps limit further joint damage and preserves knee function. Many minor cartilage injuries respond well to minimally invasive keyhole surgery. Prompt treatment also reduces the risk of muscle weakness and stiffness. Delaying care allows cartilage tears to enlarge over time. As damage progresses, the chance of developing osteoarthritis increases.

Modern Cartilage Repair Options

Whenever possible, surgeons aim to repair cartilage rather than remove it. Preserving native tissue supports better joint mechanics in the long term. Although healing takes time, repaired cartilage offers better protection for the knee. Biologic injections may support the healing process in selected cases. These treatments can help reduce inflammation and improve the joint environment.

Meniscal Repair and Replacement

Treatment depends on the location and severity of the tear. In suitable cases, surgeons perform meniscal repair to preserve the tissue. When repair is not possible, partial removal or meniscal replacement may be considered. Age, activity level, and overall knee health guide these decisions. For this reason, treatment plans should always be personalised.

When to See a Doctor

Persistent knee pain should never be ignored. Swelling, locking, or reduced movement also deserve medical attention.
Early assessment often leads to better recovery and improved joint preservation.

Clinical Evidence Supporting Repair and Preservation

Scientific research supports preservation-based treatment and biological support for knee injuries.
