Pinless Computer Navigated Total Knee Replacement- most advanced technique

September 26 2016 , Written by Ambika

 

This is a big boon for the patients with KNEE DEFORMITIES and LEG DEFORMITIES undergoing knee replacements. Computer navigated knee replacement assures complete correction of these deformities. It also decreases the chances of life threatening complication of fat embolism, as one need not drill hole in the medullary canal of the thigh bone.

Pinless Computer Navigated Total Knee Replacement done by Dr Anil Arora (Head of Unit and Lead Consultant,Department of Orthopaedics Max Super Speciality Hospital, Patparganj, Delhi) for Knee Replacement. Dr . Anil Arora in North India is pioneer in this Technology .

Dr . Anil Arora was kind to take some time and talk through about this new technology which makes easier for patients to recover and how technology is new generation in surgery ....

What Is Computer Navigated Knee Replacement Surgery?

The technology of knee replacement has undergone sea changes in last one decade. Total knee replacement nowadays gives predictable and excellent results. Millions of Knee joints are replaced annually throughout the world. In orthopaedic surgery, there is a well-recognised relationship between accuracy and outcome. The surgeons experience in patients’ selection, soft tissue balancing, the alignment of the leg, the restoration of the joint line and also the prosthetic design are all possible factors influencing the success of Knee Replacement. With the help of advancements in computer technology, the surgeons and researchers are constantly working towards achieving perfection in each surgery. One such example is Computer Navigated Knee Replacement Surgery.

 

The procedure of Total Knee Replacement consists of replacing the damaged articular surface of the knee with a knee prosthesis (artificial knee). The position of this implanted knee influences the outcome. The positioning of this implanted knee (artificial Knee) has been conventionally performed and assessed with the use of manual alignment jigs. Despite the continuing improvement in mechanical alignment systems, it has been estimated that the error in (tibial and femoral) alignment of over 3° may still occur in total knee replacements, even when they are carried out by well-trained surgeons, using the most up-to-date mechanical alignment tools. This is due to drawbacks of the conventional alignment systems. More recently, computer navigated systems have been developed to improve the positioning of the prosthesis (artificial knee) components, and balancing of the knee, with the goal of improving the alignment, which in turn is aimed to improve the overall survivorship and life of artificial knee. Computer navigated system for knee replacement has shown to markedly reduce outliers of misalignment of artificial knee, when compared to the conventional technique.

Similar to the alignment of the wheels on your car, a poorly aligned joint replacement will cause problems with early wear of the replacement. An incorrectly aligned joint can lead to early wear and loosening of the joint replacement. Computer navigated system for knee replacement is an additional check to confirm proper placement and balance of the artificial joint replacement.

 

This is a big boon for the patients with KNEE DEFORMITIES and LEG DEFORMITIES undergoing knee replacements. Computer navigated knee replacement assures complete correction of these deformities. Computer navigated Knee replacement also decreases the chances of life threatening complication of fat embolism, as one need not drill hole in the medullary canal of the thigh bone.

 

How it is done?

Computer navigated system for knee replacement uses special sterile probes which are touched to various parts of your knee during surgery to create a 3D Model of your knee in the computer with the help of infrared camera. With the guidance of Computer navigated system for knee replacement, knee is then replaced, and the position of implant confirmed, to be almost hundred percent sure of positioning and balancing.

What is the advancement in Computer navigated system for knee replacement?

Pin Computer navigation technology came into practice about a decade back. But it never became popular because of serious drawbacks. Earlier versions of Computer assisted replacements used drilling extra few pins in thigh and leg bones to attach Arrays (Guides). Drilling extra holes in thigh and leg bones can sometimes lead to complications (risk of bony fractures, pin site infection and bone drill hole infection). So the advantages of earlier version of computer navigation were attended with chances of some extra complications also.

The latest –state of the art- Pinless Navigation does not require drilling extra holes in thigh and leg bones. The latest state of the art PINLESS Computer navigation is recommended rather than using earlier versions of pins. Use of pinless Computer Navigation avoids risks and complications associated with earlier version i.e. pin computer navigation. Pinless navigation is an effective tool for reducing the proportion of outliers, without significantly increasing the duration of surgery and risks. Prof Anil Arora is using this Pinless Computer Navigation System in his cases. This gives advantages of accuracy without increasing the risk of complications. This is the first Pinless system in North India and it is giving excellent results. Prof Anil Arora specializes in performing Primary, Complex and Revision Knee Replacement and Hip Replacement surgeries.

 

Summary

  • Computer navigated surgery is a state-of-the-art surgical technique which lifts the accuracy of knee replacement surgery from around 80 per cent to up to 99.9 percent, thus improving the longevity and functioning of the replace joint.
  • Computer-assisted surgery helps surgeons align the patient's bones and joint implants with a degree of accuracy not possible with the naked eye.
  • Instead of guessing where the mechanical axis or points of reference are the computer tells us, accurately where they are, and it's accurate to within one or two degrees. Much like the tread life of tires is prolonged by a wheel alignment, exact alignment of a knee replacement assures the maximum longevity of a total knee replacement.
  • Everyone is different and so are their knees! Computer navigated surgery takes into account each patient’s shape and size of the knees and allows a surgeon to use, what is essentially a mini GPS system, to register the exact bio-mechanic anatomy of the leg and knee joint to ensure each replacement is as accurate as possible.

Alzheimer’s can also affect the young

September 21 2016 , Written by Ambika

f you thought Alzheimer’s only affected the elderly, of late there have been cases of early-onset of Alzheimer affecting young adults in the age group of 30-40. According to the Alzheimer’s Association, early onset of the disease has been seen among 5 percent of the Alzheimer’s affected population. Even though it is a rare case, the doctors say that due to the exponential growth in Alzheimer’s patients especially in India, it is extremely critical to be aware of Alzheimer and its symptoms.

“Early onset Alzheimer mostly affects young adults with either a family history in Alzheimer or dementia or due to specific mutations. Although early-onset of Alzheimer has no cure, proper diagnosis and right kind of treatment can go a long way in slowing the process of Alzheimer,” said Dr. Anil Ramakrishna, Consultant Neurologist, Columbia Asia Hospital, Hebbal. With World Alzheimer’s Day on 21st September it is critical to create a mass awareness on this subject.

According to estimates of the Alzheimer’s and Related Disorders Society of India (ARDSI), there were around 3.7 million Indians with dementia in 2012. These numbers are expected to cross seven million by 2030, imposing a huge financial as well as societal burden on the country.

“Dementia is not a normal part of aging as many people believe. It is a neurological disorder and it has a varied set of symptoms. These symptoms are often overlooked as family members mistake them for age-related forgetfulness. Being aware and watchful for symptoms and seeking medical advice may enable an early diagnosis, paving the way for timely treatment that can slow down the symptoms and mitigate distressing problems in some patients,” added the doctor.

Finding it difficult to remember things, asking the same questions repeatedly, having trouble paying bills or doing simple math problems, getting lost, losing things or putting them in odd places are some of the early signs and symptoms that one can look out for. Later signs of Alzheimer's include forgetting how to take care of personal hygiene, being confused about time, place and people, forgetting names and wandering away from home.

Here are a few tips by Dr. Anil that can help reduce the risk of acquiring Alzheimer’s disease:

  • Physical Exercise: Regular physical exercise can reduce the risk of acquiring Alzheimer’s disease. Brisk walking, running, cycling, indulging in sports like swimming etc. throughout one’s life can help reducing the risk.
  • Mental Exercise: People with greater mental agility and activity are believed to be at lower risk of acquiring dementia. It is very essential that people continue to stimulate the brain by solving puzzles, reading and writing and indulging in peer group activities.
  • Eat Brain Healthy food: Food rich in omega 3 fatty acids are recommended to keep the brain healthy. Including walnuts, fish, soybean and flax seeds in your diet will help reduce the risk. A research published recently in the journal Neurobiology of Aging, concluded that coffee consumption can be a deterrent to Alzheimer’s. Coffee’s effects on the central nervous system may have to do with this link.
  • Be watchful for symptoms: Dementia starts with mild symptoms of memory loss. A degenerative brain disorder like Alzheimer’s cannot be reversed or cured. But, its progression can be delayed, if it is diagnosed early. Therefore, it is important for the family members to be alert about spotting any such symptom in an elderly and immediately report it to the doctor.

Everything you need to know about Chikungunya

September 20 2016 , Written by Ambika

With more than 1000 cases reported in Delhi till now, it has become extremely important to understand Chikungunya and its prevention. According to World Health Organization (WHO), the disease shares symptoms with dengue and can be easily misdiagnosed especially in areas where dengue is common.

“Chikungunya is characterized by an abrupt onset of fever frequently accompanied by joint pain. Other common signs and symptoms include muscle pain, headache, nausea, fatigue and rash. The joint pain is often very debilitating, but usually lasts for a few days or may be prolonged to weeks,” said Dr Narendra Prasad, consultant, General Medicines, Columbia Asia Hospital, Hebbal.

“Most patients recover fully, but in some cases joint pain may persist for several months, or even years. Occasional cases of eye, neurological and heart complications have been reported, as well as gastrointestinal complaints. Serious complications are not common, but in older people, the disease can rarely contribute to the cause of death. Often symptoms in infected individuals are mild and the infection may go unrecognized, or be misdiagnosed in areas where dengue occurs,” added the doctor.

The virus is transmitted from human to human by the bites of infected female mosquitoes. Most commonly, the mosquitoes involved are Aedes aegypti and Aedes albopictus, two species which can also transmit other mosquito-borne viruses, including dengue. These mosquitoes can be found biting throughout daylight hours and are found biting outdoors, but Ae. aegypti will also readily feed indoors.

“After the bite of an infected mosquito, onset of illness occurs usually between 4 and 8 days but can range from 2 to 12 days. Serological tests, such as enzyme-linked immunosorbent assays (ELISA), can confirm the diagnosis with presence of IgM and IgG anti-chikungunya antibodies, “said Dr. Prasad.

The most common signs and symptoms of Chikungunya are:

  1. Flu- chills, fever, headache and aching joints
  2. Joint pain can particularly occur in hands, wrist, ankles and feet which can last from weeks to months and can even continue for a year
  3. Nausea
  4. Fatigue
  5. Rashes

“Treatment of chikungunya is directed primarily at relieving the symptoms, including joint pain and rehydration,” added the doctor.

Prevention and control relies heavily on reducing the number of natural and artificial water-filled container habitats that support breeding of the mosquitoes.

Here are a few tips by Dr Narendra Prasad to protect yourself from Chikungunya:

  1. Wear full length cloths to minimize skin exposure
  2. Apply skin repellents to exposed skin
  3. Use nets especially while sleeping during the day hours
  4. Don’t let water accumulate near your surroundings
  5. Check for overflowing garbage bins
  6. Empty flower vessels and change the water to avoid mosquito breeding
  7. Make sure the bathrooms are dry and toilet seats are down when not in use
  8. Mosquitos are generally attracted to smells like perfume and sweat. Shower to remove sweat and use unscented shampoos
  9. Spray mosquito repellent that contains DEET, if you have balcony garden or one in the veranda. You can grow marigold and lemon grass as they are natural insect repellent
  10. Use plug-in, smokeless mosquito repellent and Limit the use of smoke coils to outside or well ventilated indoor areas
