There are different types of knee surgeries, including:

Arthroscopy

This minimally invasive procedure allows the surgeon to visualize the inside of the knee joint using a small camera called an arthroscope. It is commonly used to repair torn ligaments, remove loose fragments, or smooth damaged cartilage.

Partial Knee Replacement

In this procedure, only the damaged part of the knee joint is replaced with an artificial implant. It is suitable for patients with localized knee arthritis.

Total Knee Replacement

This surgery involves replacing the entire knee joint with an artificial implant. It is typically recommended for patients with severe knee arthritis or significant joint damage.

Joint replacement: Our team of skilled orthopedists specialize in hip, knee, and shoulder joint replacement. We are well-versed in the latest minimally invasive techniques and utilize advanced treatments for optimal surgical results, quicker recovery, and minimal scarring and pain. Learn more

ACL Reconstruction

Anterior Cruciate Ligament (ACL) reconstruction is performed to repair a torn ACL, a common knee injury among athletes. The surgeon replaces the damaged ligament with a graft, usually taken from the patient’s own body or a donor.

Meniscus Repair

Meniscus tears are common knee injuries. In this procedure, the surgeon trims or repairs the torn meniscus to restore normal knee function.

One of our qualified orthopedic surgeons can evaluate your condition and recommend the most appropriate treatment option for you.
