knee replacement surgery in Bangalore
Knee replacement or knee arthroplasty
This is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability. It is most commonly performed for osteoarthritis, and also for other knee diseases such as rheumatoid arthritis andpsoriatic arthritis. In patients with severe deformity from advanced rheumatoid arthritis, trauma, or long-standing osteoarthritis, the surgery may be more complicated and carry higher risk. Osteoporosis does not typically cause knee pain, deformity, or inflammation and is not a reason to perform knee replacement.
About Total Knee Replacement Surgery:
In 1968, the first ever total knee replacement surgery was carried out successfully and ever since then there has been immense improvement in relieving the knee pain and let patients to get back to their active lives. New Surgical techniques and implant design and construction has been playing a vital role in making the total knee replacement technology a huge success in orthopedic field today. The need for knee replacement technology is growing with each passing day with the increase in the population as it continues to remain active. As per the survey, about 270,000 knee replacements are carried out every year in the United states alone.
We are best known for our advancements in the knee replacement surgeries. The Hip and knee surgeons have contributed a few techniques to improvise the replacement procedure, their contribution includes the surgical techniques and the design of new implants.
The knee joint mechanism is similar to that of hinge joint, but with the addition of straightening and bending. In fact, the knee joint mechanism is more complex than a hinge joint mechanism, since in knee joint, the surfaces are glide and they roll upon one another making it a complex technique. it is the composition of the three bones, namely, the patella(kneecap), the femur(end of the thigh bone) and the tibia(top of the leg bone).
The articular cartilage, a smooth and glistening layer is used to cover the ends of the bone, which is the main reason for the bones to slide smoothly as possible with low resistance than that of 2 ice cubes sliding with each other. In short, the space between the bones is what we call articular cartilage which can be easily seen in X ray report.
The knee concept is similar to having 3 chambers – the medial, the lateral and the patellofemoral. 2 more special cartilages are there, which is known for it’s shock absorption mechanism within the knee joint called as lateral and medial meniscus. In addition, there are also 2 ligaments which is the source of knee stability, called as the interior cruciate ligament and the posterior cruciate ligament.
Losing the articular cartilage of the femur, tibia or patella results in a condition which is widely known as knee arthritis. This can be visually seen through X ray scanning, where there will be a loss of the space in between the 2 ends of the bones.
People who suffer with Arthritis usually think their walking ability is decreasing and often feel that their knee is rigid. This is due to the loss of the gliding surfaces of the bone. They may also feel like catching or clicking within the knee sometimes. The pain that people with Arthritis go through may become worse when they walk long distances or stand in queue for long time or climbing stairs. With dreadful pain, people may suffer even while sitting or lying down. Inside part of the knee is where the pain felt usually, but pain may also be felt in the front or back of the knee. People feel that their knee has become bow-legged or knock-kneed when the cartilage is tattered preferentially on one side of the knee joint.
Arthritis may be found more in people aged 60 or 70 or above, this also depends on few elements like weight, activity level and knee anatomy. Even a simple wear and tear or inflammatory disorders like lupus or rheumatoid arthritis, infection or post-traumatic can cause Arthritis.
People who have suffered knee injury earlier or damaged meniscus or cruciate ligament may also develop arthritis. The final outcome of all these actions may lead to loss of the cartilage of the knee joint, in turn leading to bone rubbing against bone.
