Why Need Of Knee Replacement ?

Knee replacement is the most common joint replacement surgery. The main reason to have knee replacement surgery is to ease pain and disability caused by arthritis or other joint problems, while preserving movement.

What is the age Group for knee replacement?

Now Due to Busy lifestyle and increasing ratio of obesity making knee problems very common in mid age and not just senior citizens.

What is the Common Current Treatments?

Finally Knee treatments are totally decided after total diagnosis and doctor’s initial observations but if there is severe problem in knee and patient is not properly mobilised then knee surgery is the only option.

What is the Total Knee Replacement?

Total knee replacement, or total knee arthroplasty, is a surgical procedure in which parts of the knee joint are replaced with artificial parts (prostheses)

What is the Partial Knee Replacement?

Partial knee replacement is a surgical treatment option that replaces (or resurfaces) only the damaged portion of the knee while conserving knee ligaments and unaffected cartilage.In both the cases surgeons expertise and accuracy plays major role.

What is Robotic Knee Surgery ?

Robotic knee surgery is robotic-arm assisted technology that provides you with a personalized surgical plan based on your unique anatomy. A 3D model of your hip or knee will be used to pre-plan and assist your surgeon in performing partial knee replacement.

Why Robotic Knee Surgery is better Option ?

Comparison of Robotic Assisted Knee Surgeries over Normal Knee Surgeries Most Important benefits of Robotic Assisted Knee Surgery is It helps surgeon to make surgery successful with high accuracy, In normal knee surgeries it is totally depend on surgeon visual observations.
In Robotic Assisted Knee Surgery due to high precision it brings back more natural leg and knee movements over normal knee surgeries
In Robotic Assisted Knee surgery surgeon has to operate only on damaged portion so less damage to other tissues , bones and less blood loss.
Due to less Damage to other tissues and less blood loss patient can get quick discharge from hospital in 24 to 48 hours after surgery.
Due to High Accuracy in Robotic Assisted Knee Surgery recovery of patient is faster than normal knee surgeries. Due to precise robotic assisted knee surgery and high accuracy medication after surgery is very less.
Note : Only Surgeon can decide that whether patient should go for robotic knee surgery or normal knee surgery after initial diagnosis and observation.

What are joint pains?

Joint pain is a common complaint which refers to erratic or constant discomfort, aches, and soreness in any of the joints of the body. One may feel it in the knees while walking or in the shoulders while lifting an object. Sometimes, joint pain is the result of an illness or injury while in some cases arthritis can also be a common cause of joint pain. Other factors such as vitamin deficiencies, harsh weather conditions, improper postures, etc, can also cause joint pains.

Is Joint Pain a serious health problem?

Your body can give various signals if the joints are in trouble. Visit a doctor if you don’t know the cause of your joint pain and are experiencing symptoms such as if the area around the joint is swollen, red, tender, or warm to the touch, the pain persists for three days or more, or you have a fever but no other signs of the infections. Also, rush to an orthopedic specialist if any of the following occurs:

  • You’ve received a serious injury
  • The joint appears deformed
  • Sudden swelling of the joint and stiffness
  • The joint is completely immobile
  • You have severe joint pain
  • Your daily activities like walking, lifting objects, changing posture like getting up from chair, climbing stairs are getting hampered

What is Arthritis?

Arthritis is an inflammation of the joints. It can affect one or multiple joints in the body. There are more than 100 different types of arthritis and each having different causes and treatment approach. Two of the most common types are Osteoarthritis (OA) and Rheumatoid Arthritis (RA). The symptoms of arthritis develop over time, but they may also appear early. Arthritis is more common among adults aged 65years or older, but it can also develop in children, teens, and younger adults. Arthritis is more prevalent in women than men and in people who are overweight. It is a broad term for a host of joint ailments and a proper diagnosis is required to determine the cause and treatment of this ailment.

What are the symptoms of arthritis?

The most common symptoms of arthritis are joint pains, loss of flexibility, cracking sounds, mild swelling around a joint. One may also find difficulty in movement or the presence of stiffness in the concerned joint area. Many people with arthritis experience symptoms worse in the morning hours and more so in the winter season.

In the case of Rheumatoid Arthritis (RA), one may also feel tired or experience a loss of appetite due to the inflammation that the immune system’s activity causes. The person may also become anemic (decreased red blood cell count) or have a consistent slight fever. Severe RA can cause joint deformity if left untreated.

What is Rheumatoid Arthritis (RA)?

Rheumatoid arthritis (RA) is a long-term, progressive, and an autoimmune disease that causes inflammation, swelling, and pain in and around the joints and other body parts. The body’s immune system, which normally protects the body from the bacteria and virus attacks – mistakenly, attacks the joints. As a result, inflammation occurs in the target tissue or organ. Rheumatoid Arthritis most commonly affects the joints of the hands, feet, wrists, elbows, knees and ankles. The tendons and ligaments that hold the joint together can also weaken and stretch over a period of time. Ligaments connect the bones to each other while tendons connect muscles to the bone. In Rheumatoid Arthritis, the joint eventually loses its shape and configuration and as a result the damage can be severe. Symptoms include:

  • pain, swelling, and stiffness in more than one joint especially upon getting up in the mornings or after sitting down for a while
  • symmetrical joint involvement, the same joints on both sides of the body
  • joint deformity
  • unsteadiness when walking
  • a general feeling of being unwell
  • fever
  • loss of function and mobility
  • weight loss
  • weakness

What is Osteoarthritis (OA)?

Osteoarthritis (OA) is the most common type of arthritis affecting millions of people worldwide. It occurs when the protective cartilage on the ends of bones at the joint wears down over time. As a result, the bone then starts to rub against other thereby causing pain, swelling and stiffness. Although osteoarthritis can damage any joint in the body, the disorder most commonly affects joints in hands, knees, hips, lower back and spine. Common risk factors include:

  • Increasing age
  • Gender: Females are more at risk
  • Obesity
  • Previous joint injury
  • Occupational factors, overuse of the joint
  • Weak muscles
  • Genetic causes
  • Metabolic or hormonal disorders

Is Osteoarthritis (OA) more common in women?

Unfortunately, osteoarthritis (OA) is more likely to affect women than men. By nature, women face a triple threat of risk factors when it comes to arthritis: biology, genetic predisposition, and hormones. Many women past age 50 discover Osteoarthritis is the reason for their creaking knees, aching backs, and sore fingers. As osteoarthritis worsens over time, bones may break down and develop growths called spurs. These extra bits of bone feel like hard lumps and may form around the affected joint. While in men, arthritis in their hips is more common, in women the knees or hands are more vulnerable.

Does arthritis affect one’s day to day life?

Pain, swelling or stiffness can make it difficult to perform day to day tasks. Simple acts like making the bed, opening a can of food, holding a plate or a cup of tea or driving can become difficult. Patients with severe arthritis in their hands are unable to even flip the pages of a newspaper. In cases where arthritis inflicts the lower body joints; activities such as walking, climbing stairs, performing exercises and lifting objects may become difficult. Moreover, people with osteoarthritis experience more falls and have greater risk of fracture than those without osteoarthritis.

Can Arthritis be managed or controlled?

While one can control arthritis, it is sometimes difficult to completely cure or eradicate it. An arthritis patient must take extreme care of his health and make necessary lifestyle changes that will benefit in keeping arthritis under control such as:

    • 1. Keep the joints moving – Sedentary lifestyle with minimum activity makes joints stiffer. Light stretching and slow walks keep the joints flexible and moving.
    • 2. Maintain the right posture – Long hours of sitting hunched over your laptop can create havoc with both your knees & shoulder joints. Similarly standing in a stooped manner adds pressure to the neck and back which can worsen your issues in the long run.
    • 3. Maintain healthy body weight – Being overweight or obese can increase arthritis and contribute to arthritis pain, especially if one is a knee patient.
    • 4. Quit smoking – Smoking causes stress on connective tissues which can further increase arthritis pain. Give it up!
    • 5. Avoid high impact activities that can add stress to your muscles such as running, jogging, jumping, high-powered sports, etc.
    • 6. Over-the-counter pain medications can help relieve occasional bouts of pain triggered by over-exertion. But they have side effects on Kidneys and other organs therefore make sure you visit an orthopedic specialist if the pain is recurring and refuses to subside with medication.

When should one consult an orthopedic doctor or surgeon?

If a person is plagued with arthritis symptoms like recurring pain in the joints, stiffness, lack of flexibility, difficulty in performing simple tasks, consistent fatigue, low-grade fever, aches while moving any joint, constant creaking or grinding noises, limited or no relief from painkillers; immediately consult the best orthopedic surgeon who can carry out the necessary tests to determine if the patient is experiencing generic pains or is it the stage of arthritis.

How are ailments like arthritis or osteoporosis diagnosed?

A proper diagnosis of the ailment is the first step toward a successful treatment. In order to detect if you are suffering from joint conditions like arthritis or osteoporosis, your doctor will consider all your symptoms, physically examine you to check for swollen joints or loss of motion, and opt for blood tests and X-rays to confirm the diagnosis. X-rays and blood tests will also help distinguish the type of arthritis you have. For example, most people with Rheumatoid Arthritis (RA) have antibodies called Rheumatoid Factors (RF) in their blood which can be detected through a series of proper tests. Similarly X-rays are best used to diagnose osteoarthritis, typically revealing a loss of cartilage, bone spurs, and in extreme cases, bone rubbing against bone. DEXA (Dual Energy X ray Absorptiometry) scan is very helpful in assessing bone density authentically with minimal radiation exposure.

What is the treatment for Arthritis?

Broadly, the range of treatment for arthritis includes rest, occupational or physical therapy, exercise, drugs, and sometimes surgery to correct joint damage. Depending on the severity of the condition, the orthopedic doctor will determine the course of treatment. If arthritis is detected in the beginning stages itself, then proper medication, physiotherapy and lifestyle changes may suffice in controlling your arthritis. But if the stage is severe, then joint replacement surgery is often the best and most successful treatment for arthritis.

What are the dos and don’ts for Arthritis patients?

  • a. Do not rely excessively on over-the-counter pain killers to treat your arthritis. They may offer temporary relief but are not the solution to cure the disease.
  • b. Visit your orthopedic doctor and share all the symptoms and issues you are facing with your joints.
  • c. Practice a healthy lifestyle – good eating habits, regular exercise, balanced sleep patterns and eradicate alcohol and smoking completely.
  • d. Do not get into high impact activities that can add added pressure to the joints.
  • e. Ensure proper post-operative care and regimen.

Are the cases of orthopedic surgeries on the rise?

In current times orthopedic surgeries have become common in all parts of the world. Higher incidences of arthritis as well as sophisticated and technologically advanced treatments available today have made it possible to help patients deal with their arthritis in a more holistic manner. The most common orthopedic surgeries are of the knee, shoulder, elbow, wrist, hip and ankle.

How does one identify if there is a need for surgery?

An orthopedic doctor will only recommend surgery if all other treatment modalities have failed to relieve the patient’s discomfort or to restore mobility and joint function. If arthritic pain and inflammation become persistent and the arthritic joints are majorly damaged, then the answer may lie in surgical joint replacement.

Today, the affected joints can be replaced with reliable and good quality artificial joints made of inert metals and ceramic materials which are non allergic and better acceptance by the body. All the major and smaller joints can be surgically treated to offer the patient a pain-free life.

What is knee replacement surgery?

A knee replacement surgery is done when the joints in your knees have extremely damaged and medication or non-surgical methods will not suffice further. In knee replacement surgery; damaged, worn or diseased cartilage and bone in your knee joint are replaced with an artificial joint to enable the movement similar to that of a natural joint.

What is Total Knee Replacement (TKR)?

One may require either a total or a partial knee replacement depending upon the condition of the knee joints. In Total Knee Replacement (TKR) surgery, both sides of the knee joints are replaced with artificial implants. This is usually performed when the joint is severely damaged by Osteoarthritis, Rheumatoid Arthritis, and Post-traumatic Arthritis or due to Vascular Necrosis.

In a normal joint, the joint surface is covered by cartilage that provides a smooth articulating surface that allows for smooth movement within the joint, whereas in arthritic joint the cartilage is gradually worn out which causes the bones to rub against one another leading to pain and restricted range of motion. The goal of the surgery is to relieve pain and restore the normal functioning of the joint. Total joint replacement can be performed through two approaches: conventional approach or minimally invasive approach.

In the conventional approach, an incision is made over the affected joint. The arthritic part of the joint is removed and prepared to receive the artificial components. The artificial components are fixed in place and the muscles and tendons are then repaired and the skin is closed. It normally has longer recovery time due to more amount of bone cutting and risk of damage to supporting structures and soft tissue.

With advancements in technology, a minimally invasive approach has been developed in recent years where surgery is performed through smaller incisions. With the help of technology the precision has improved and there is a higher grade of accuracy. Advantages of the newer approach are lesser soft tissue damage, preserved bone, ligaments and soft tissue, minimal pain, quicker recovery and faster rehabilitation of the patient.

What do you mean by Partial Knee Replacement/Unicompartmental Knee Replacement (UKA)?

Partial Knee Replacement also known as Unicompartmental Knee Arthroplasty (UKA) is a surgical treatment option that replaces only the damaged portion of the knee when only one compartment of knee is affected, while conserving knee ligaments and unaffected cartilage. It is a minimally invasive procedure in which only the diseased or damaged joint areas are removed and replaced with artificial surfaces while leaving the healthy parts of the joint intact. This treatment is followed only when all possible conservative means of treatment such as rest, anti-inflammatory medications, physiotherapy have been ineffective in resolving the symptoms.

There are three basic steps in the procedure:

  • Prepare the bone. Your surgeon will first map the damaged area and use surgical burs to remove the diseased part from the damaged compartment of your knee.
  • Position the implants. The removed cartilage and bone is replaced with coverings that recreate the surface of the joint. These parts are typically held to the bone with cement.
  • Insert a spacer. A meniscus substiute insert is placed between the two metal components to create a smooth gliding surface that helps improve the condition of your joint.

What is Minimally Invasive Surgery?

Technology has come a long way in the field of medical practice. In traditional open surgery, the surgeon makes one large cut to see the part of the body that they’re operating on. On the other hand, minimally invasive surgery allows the surgeon to use techniques that limit the size incisions which they need to make on the patient’s body. Here through a smaller incision the joint structure is exposed, minimal soft tissue and supporting structure damage, blood loss is also less and infection rate is lower and recovery is faster.

What is Arthroscopy?

Arthroscopy is a minimally invasive form of surgical procedure doctors use to diagnose and treat the joint problems. The technique of arthroscopy involves inserting the Arthroscope, a small tube that contains optical fibers and lenses as small as a tip of a pen, through a tiny incision in the skin into the joint to be examined. This way the most minimum amounts of cut is required. The arthroscope is connected to a video camera and the interior of the joint is seen on a television monitor. Arthroscopy patient shows faster recovery. The conditions in which Arthroscopy is recommended are limited which mainly include Meniscal repair, ACL or PCL repair etc. There is high success rate with limited scope.

What is Arthroplasty?

Arthroplasty is a surgical procedure performed by an orthopedic surgeon that alters or completely replaces a joint in the body, commonly known as joint replacement surgery. This is usually done to restore normal motion and relieve pain in a malformed or diseased joint, such as the hip, knee, shoulder, elbow or ankle.

Depending on the severity, the surgeon will determine whether Partial or Total Arthoplasty is required. If the damage is restricted to one compartment, the orthopedic surgeon will do the resurfacing of only one part of the joint and replacing it with implant prosthesis in an attempt to restore joint function called Unicompartmental Knee Arthroplasty. In the Total Knee Arthroplasty, more than one compartment is affected, therefore the damaged areas are cleaned resurfaced and replaced with implant prosthesis for pain relief and restoration of joint function.

What is Robotic Knee Replacement Surgery?

Robotic Knee Surgery is a highly advanced medical practice that has revolutionized joint replacement surgeries in the field of orthopedics. Dr. Narendra Vaidya is the pioneer of Robotic-Assisted Knee Replacement Surgery in India. The technology adds an unparalleled level of surgical accuracy and precision in knee replacement surgery and has shown significantly improved accuracy of alignment and joint-line restoration.

Firstly, it helps the surgeon create a highly individualized plan that is specific to the unique shape and structure of the knee. In robotic assisted surgeries, no endless scans or x-rays are required. Thus one is not exposed to the potentially harmful radiation experienced in this type of imaging.

The second benefit is robotic assistance. The surgeon uses robotic assistance to physically remove only the damaged bone, preparing the site for the prosthesis, before placing and adjusting your knee implant. This combination of advanced technology results in more accuracy and better long-term functional outcomes.

What are the pros of Robotic Knee Replacement Surgery?

The accurate and precise nature of robotic-assisted surgery comes with several benefits:

  • More accurate implant positioning
  • Improved safety and reduced risk of injury to adjacent tissues
  • Small incisions, which can result in shorter hospitalization and less pain.
  • Replacing only the damaged components of the knee joint results in a more natural Joint structure and movement of the joint.
  • It also facilitates a quicker recovery and return to normal activities.

Why Robotic Knee Surgery is better option than traditional Knee Replacement Surgery?

With advanced technologies and developments, sophisticated treatments are preferred over traditional methods. Similarly, Robotic Knee Replacement surgeries are becoming increasingly popular because of the following reasons:

  • It helps thesurgeon to conduct the surgery with higher accuracy owing to tech support, while in conventional knee surgeries it is totally dependent on surgeon’s visual observations.
  • RoboticAssistedKnee Surgery is minimally invasive therefore postoperative blood loss is lesser further adds to faster recovery.
  • In Robotic Assisted Knee surgery, proper mapping of damaged part is possible and surgeon has to clean and resurface only the damaged portion and ligaments, patella and supporting structures are preserved, there is less damage to other tissues, further contributes to faster recovery.
  • Length of stay is for lesser period than conventional, post operative rehabilitation is easier and deformity is corrected completely.

Can one start walking normally post knee replacement surgery?

Yes, today with modern medical treatments like Robotic Assisted Knee Surgery, recovery time is noticeably faster in patients and many start walking quite early post thesurgery. Basic post-operative care is mandatory for every patient and following proper exercise regime as per the advice of physiotherapists, ice pack application, basic drug support and nutritious balanced diet further help in speeding up the recovery process. After Minimal Invasive Robotic Assisted Knee Replacement Surgery, there is no need for prolonged resting, rigorous physiotherapyand heavy medicines.Instead,the patient is made to walk onthe same or next day of the surgery and even the hospitalization period is very less. The patient enjoys quick recovery in the comfort of his home and is able to perform all his activities by himself.
