New Delhi, December 29
A two-day international symposium on Mobile Bearing Total Knee Anthroplasty
(TKA) or knee replacement, the first of its kind in north India, began at Indraprastha Apollo Hospital here today.
Speaking on the occasion, Dr Rajeev K. Sharma, symposium director and Senior Orthopaedic Surgeon, Apollo Hospital said, “Arthritis is the fate of mankind. All of us are destined to have it at some point in our life. TKR represents a major advancement in the management of severe, crippling arthritis. More than three lakh patients undergo TKR each year in the US alone. In India also, although the technique is relatively new, more than 6,000 patients undergo this surgery, which is among the most successful procedures in orthopaedic surgery.”
The symposium will explore the technique, its design evolution and clinical experience, he said. More than a hundred surgeons from all over north India are attending the symposium, where a major highlight will be the presentation from Dr Jeans-Louis Briard from France, who has pioneered the computer-assisted
TKA.
“Total Hip Replacement is already a well-accepted operation today but total knee replacement is still in the process of gaining acceptance as it is a more demanding surgical technique. However, with a deeper understanding of this technique, patients today can expect excellent and more reliable results. This implies pain-free mobility and a stable joint which is nearly normal,’’ pointed out Dr
Briard.
The knee is a ‘hinge type’ joint, which is formed by the thighbone (femur) and shin bone (tibia) held together by flexible ligaments. The moving parts of a normal knee are covered with a layer of cartilage.
However, after a certain age, arthritis sets in and the cartilage is so badly worn out at knee joints that the person experiences discomfort in normal motor functions like alighting stairs, standing up, sitting down or simple walking.
The TRK has been accepted as one of the most successful orthopedic procedures and allows for vertical movement so that the leg can easily bend. But the mobility, which takes place in the knee is more complex and also includes some horizontal rotation.
“With the invention of mobile bearing artificial knee, more congruency and lesser wear has resulted in increased life span of the artificial joint. Recent reports have shown extended survivorship of up to 25 years, especially in the younger and active age group of patients,” added Dr
Briard.
Dr Sharma added that the technique would be a boon for the Indians.
“A very common predisposing factor for setting in of early arthritis in our female population is bow-leg deformity, in which the bones slightly curve onwards at the joints. This causes disproportionate overload on the weight-bearing joints, causing wear at certain points.”
He also attributed obesity, coupled with a sedentary or passive lifestyle as a major factor that almost guaranteed the setting in of degenerative arthritis in the general population.
