Knee Osteoarthritis – Should I Go for a TKR (Total Knee Replacement)? Knee Osteoarthritis – It is a painful condition of the knee joint where the smooth lining (articular cartilage) of the ends of the thigh bone and shin bone forming the knee joint becomes worn out or rough. It causes stiffness, pain, swelling and … Continue reading

Avascular Necrosis of the Knee Joint | Role of a Partial Knee Replacement

What is Avascular Necrosis of the Knee? Avascular necrosis is a disease resulting from the temporary or permanent loss of blood supply to the bones. Without blood, the bone tissue dies, and ultimately the bone may collapse. If the process involves the bones near a joint, it often leads to collapse of the joint surface. … Continue reading

Enhancing Cartilage Repair in the Knee Joint | Enhanced Microfracture

Cartilage Repair using Microfracture The articular cartilage of the knee joint covers the underlying bone of the knee and cushions it from shock during walking and running activities. Damage to the articular cartilage can lead to pain, swelling and eventually arthritis. Microfracture surgery is an articular cartilage repair surgical technique that works by creating tiny … Continue reading

Repair of Torn Discoid Lateral Meniscus

Discoid Lateral Meniscus – How to Repair It A lateral meniscus is an important shock absorber for the lateral compartment of the knee joint. Whilst the medial compartment of the knee joint is largely convex (femur end) and concave (tibia end) and hence conforming even in the absence of the medial meniscus, the lateral compartment … Continue reading

I treat about 3 to 4 such cases each year. Although it can affect any joint in the body, the most common joint with this problem that … Continue reading

Cartilage Repair Using Autologous Chondrocytes – The Implantation

Cartilage defects of the knee joint can be repaired using cultured cartilage cells taken from the patient’s knee cartilage. The indications, contraindications and biopsy of the cartilage were previously discussed. You can click on this link to read the article. Click Here. In this article, I will explain how the cultured cartilage cells are implanted … Continue reading

Knee Pain – Could it be a Meniscus Tear?

One of the common cause of sudden knee pain is a meniscus tear inside the knee joint.  The meniscus is a crescent shaped piece of fibro-cartilage between the ends of the thigh bone and shin bone inside the knee joint.  Each knee has 2 menisci – a medial meniscus and a lateral meniscus. The meniscus serves as a … Continue reading
