Knee Replacement Surgery

001

A Closer Look At The Knee

The Knee is the largest joint in the body and is central to nearly every routine activity. The knee joint is formed by 3 bones: the lower end of the thigh bone (femur), the upper end of the shin bone (tibia), and knee cap (patella). Thick, tough tissue brands called ligaments connect the bones and stabilize the joint. A smooth, shiny, plastic-like lining called cartilage covers the ends of the bones and prevents them from rubbing against each other, allowing for flexible and frictionless movement. Cartilage also serves as a shock absorber, cushioning the bones, from the forces between them. A soft tissue called synovium lines the joint and produces a lubricating fluid that reduces friction and wear.

Arthritis – The leading Cause of Knee Pain

02

One the most common causes of knee pain and loss of mobility, is the wearing away of the cartilage lining. As a result, the bones rub together causing significant pain and swelling, a condition known as Osteoarthritis.

Non-operative treatments such as steroidal and non-steroidal anti-inflammatory drugs, physical therapy, alternative ‘medicine’ and cortisone injections may effectively relieve pain and restore mobility. However, increasingly severe pain and disability requires “Knee Resurfacing Surgery”.

What Is A Total Knee Resurfacing Surgery (TKR)?

03

In total knee resurfacing surgery, the parts of the bones that rub together are resurfaced with metal and plastic implants. Using special, precision instruments, your surgeon will typically remove the damaged surfaces of all three bones.

The surface of the femur (thigh bone) is replaced with a cobalt chromium component that comes very close to matching the curve of your natural bone. The surface of tibia (shine bone) is replaced with a titanium component.

This flat metal component holds a smooth plastic piece made of ultra-high-molecular-weight polyethylene plastic that serves as the cartilage.

The under surface of the kneecap may also be replaced with an implant made of the same polyethylene plastic.

The operation takes about 45 minutes to one hour for one knee resurfacing or approximately 2 hours for both knees done in one sitting.

24 – 48 Hours following surgery, your drains will be removed and you will be allowed to sit out of bed or walk under the supervision of a physiotherapist.
