Total Knee Replacement Surgery in Indore

What Is Total Knee Replacement Surgery? 

Total Knee Replacement (TKR), or total knee arthroplasty, is a surgical procedure that involves replacing an arthritic or damaged knee joint with an artificial joint comprised of metal alloys and high-grade plastic materials. This process includes taking out damaged cartilage and bone from the thighbone (femur), shinbone (tibia), and kneecap (patella), and then replacing these surfaces with artificial implants that mimic the role and function of normal knee cartilage. 

The artificial knee joint is made of several parts: a metal piece that replaces the lower end of the thigh bone (femoral component), a plastic insert that replaces the upper surface of the shin bone (tibial component), a plastic piece that replaces the underside of the kneecap (patellar component), and in some cases a metal spacer to provide extra stability. Their components are designed to deliver a natural, pain-free and  smooth movement. 

The total knee replacement is one of the most frequently performed orthopedic surgeries worldwide, and has excellent results and high satisfaction rates. The process is especially effective when the knee arthritis or injury is severe and has severely affected the patient’s quality of life, and after conservative treatment has failed. 

Why Is Total Knee Replacement Performed? 

The primary indication for total knee replacement is a severe damage to the knee joint that results in pain, dysfunction and loss of mobility. The most frequent symptom is severe, or advanced, knee arthritis, which is the name given to the disease when the cartilage that coats the knee joint has been lost over time. This results in the bone-on-bone contact that causes pain, swelling and stiffness. 

Other factors which can lead to a total knee replacement are rheumatoid, Inflammation of the lining of the knee joint (arthritis), trauma causing severe damage to the knee joint (post-traumatic arthritis), loss of blood supply causing inflammation and destruction of the knee joint (avascular necrosis of the knee) and general deformities of the knee which seriously impair function. 

The aims of TKR are to remove pain, restore normal function of the knee, increase mobility and range of motion, correct any deformity or misalignment of the knee and to improve quality of life for the patient. Patients who have this procedure frequently go on to feel dramatic results in their ability to do daily activities, hobbies and activities, and dramatic reduction or elimination of chronic knee pain. 

Who May Need Total Knee Replacement? 

Total knee replacement is generally advised when patients have a significant knee joint disease that has not responded to conservative treatment, and is causing them pain and disability. Although the total knee replacement may be performed at any age, the most common age for patients to receive a TKA is 50 years or older, but younger patients with severe joint damage may be eligible for a TKR. 

Good candidates for total knee replacement are people with very painful  daily knee activities, who have a very deforming knee which impairs their function,  those who have not gotten relief from other treatments like injections or physical therapy, have significant damage to the knee joint from previous injury, and have advanced or very severe arthritis of the knee joint. 

In addition, the candidate must be reasonably health enough to withstand surgery and anesthesia, have realistic expectations for the surgical outcomes and recovery, and be willing to commit to postoperative rehab and PT, and age/bone quality appropriate for the longevity of the prosthetics. Dr. Sanjay Rawat conducts a thorough assessment to decide whether the total knee replacement is the best treatment option for any one patient. 

Understanding the Anatomy of the Knee 

The knee is a complex hinge joint between the thighbone (the femur), the shinbone (the tibia) and the kneecap (the patella). Articular cartilage is a smooth, slippery tissue that covers the joint surface of the bones, permitting them to glide easily against one another with little friction. This cartilage measures about 2-3mm thick and distributes and absorbs the load across the joint. 

Ligaments that support the knee joint include the anterior cruciate  ligament (ACL) and posterior cruciate ligament (PCL), which provide support in the anterior-posterior direction, as well as the collateral ligaments (medial and lateral) which provide support in the side-to-side direction. The menisci are C-shaped cartilage discs  that sit between the femur and tibia, providing additional cushioning and load  distribution. 

The knee also has fluid-filled sacs (bursae) to prevent friction of tissues and muscles, including the quadriceps on the front of the thigh, the hamstrings on the back of the thigh, and the calf muscles, that move and stabilize the knee. Once any of these structures are damaged or worn, the knee becomes unable to function smoothly and the knee starts to hurt. 

Symptoms Leading to Total Knee Replacement 

Patients who come to the point of a total knee replacement usually have a progressive course of symptoms, which greatly affect their functional ability and quality of life. The most frequent symptoms include a pain in the knee area that is persistent, and can be aching, sharp or burning. Pain is often worse with 

Activities that involve weight bearing like walking, climbing stairs or standing for long periods, and may be helped by rest although in more advanced stages may cause pain when at rest. 

Swelling and inflammation around the knee joint is common, especially following activity and/or standing for extended periods of time. Patients may experience swelling of the knee which is visible and warm to touch. Another typical symptom is stiffness, usually after extended periods of rest or inactivity. Many patients say they can’t straighten or flex the knee fully, and this gradually decreases their ability to flex and straighten. 

Patients often report that their knees feel unstable or “giving way without warning,” making it dangerous to walk and potentially increasing the risk of falling.  There may be a grinding or catching of the joint that is felt, especially when the knee is moved through its full range of motion. Signs and symptoms become more severe and patients begin to describe decreased functional ability including walking for exercise, walking up and down stairs without pain, getting out of a chair, engaging in hobbies and recreation, and active lifestyle.

Diagnosis Before Total Knee Replacement 

A proper diagnosis is crucial prior to recommending a total knee replacement. Dr. Sanjay Rawat starts with a detailed clinical evaluation, which involves a thorough history taking, physical examination of knee and its surrounding structures, range of motion and stability of knee, gait pattern and functional assessment, and previous treatment that was attempted. 

X-rays are the most important imaging test to evaluate the amount of joint damage, identify bone spurs, establish joint space narrowing and alignment of the knee joint. These images offer good visualization of cartilage wear, bone changes and the overall architecture of the joint. MRI may be ordered to assess soft tissue (cartilage, ligaments and menisci), especially when further pathology is suspected or to determine the integrity of supporting tissue, such as ligaments. 

Blood tests might be done to exclude current infection or inflammatory disease that may impact surgery. Dr. Rawat ensures that all diagnostic imaging and lab results are clear and document the amount of joint damage and the indication for total knee replacement surgery. 

When Total Knee Replacement Is Recommended 

The typical criteria for recommending total knee replacement include: Imaging findings and clinical symptoms of severe knee arthritis, failure of conservative treatments (medications, injections, physical therapy) to alleviate pain and/or improve function for an adequate trial period (usually 3-6 months or more), significant functional limitation and reduced quality of life associated with knee pain and stiffness, realistic expectations of the surgical procedure and commitment to postoperative rehabilitation, favorable overall health and ability to withstand surgery and recovery, and adequate bone stock and joint anatomy appropriate for placement of the knee replacement components. 

Total knee replacement is decided on a case-by-case basis, depending on a patient’s symptoms, imaging results, functional status, age, overall health status and goals. When it comes to surgery, Dr. Sanjay Rawat takes the time to discuss the benefits and risks, as well as all options, so patients are well-informed before making this important decision. 

Advanced Surgical Techniques for Total Knee Replacement 

Dr. Sanjay Rawat has some of the most advanced surgical skills to ensure the best results and patient satisfaction. In many cases computer-assisted surgery (CAS) or navigation systems are used to ensure a precise mechanical alignment and accurate results. 

component positioning. These systems provide immediate feedback and guidance to ensure that  the components of the prosthetic device are placed at the correct angles to ensure maximum  durability and performance. 

When appropriate, minimally invasive surgical techniques are used to minimize soft tissue trauma, limit blood loss, lessen postoperative swelling/pain and promote quicker recovery. These techniques provide adequate access and visualization for proper placement of components with smaller incisions (2.5-3 inches as compared to 8-10 inches). 

Because the knees of women differ from those of men, gender-specific or anatomically optimized prosthetic parts are used. This customised approach ensures functional outcomes, better component fit, and alignment. In some cases, robotic-assisted surgery is used to achieve greater accuracy in the preparation of bones and positioning of components. 

The Procedure: Step-by-Step 

The total knee replacement surgery generally requires 1.5-2 hours from incision to closure. The patient is placed on their back (supine) with the knee that will undergo surgery exposed after being inserted with general or spinal anesthesia. A clean field is prepared and the area of surgery is meticulously cleaned using antiseptic solution. 

A cut into the skin is made over the knee joint, usually through the center of the knee, to get into the joint capsule. Soft tissues are carefully pulled aside to expose the knee joint. Specialized instruments and cutting guides are used to carefully remove the damaged cartilage and bone surfaces on the femur, tibia and patella. These guides help to make the bone cuts accurately at the right angles to achieve the correct alignment and positioning of the components. 

After preparing the bone surfaces, the prosthetic parts are carefully positioned and seated onto the prepared bone surfaces. The femoral and tibial components are either cemented (with bone cement) or press-fit (based on the tight mechanical fit and bone ingrowth). Once correct alignment and tracking is established, the patellar component is cemented to the back of the kneecap. 

Once the placement of the components are verified to be in the correct position, the surgeon checks the range of motion and stability of the new joint. The joint is well irrigated to wash out any blood or bone fragments or cement particles. The capsule and soft tissue is carefully closed in layers and the skin is closed with sutures or staples. 

Anesthesia Considerations 

Regional anesthesia (spinal block and sedation) or general anesthesia are the most common types of anesthesia used for TKA. When feasible, regional anesthesia is preferred because of avoidance of general anesthesia and excellent postoperative pain control as well as early mobilization and rehabilitation. 

Spinal anesthesia is the injection of local anesthetic around the spinal cord, which renders the lower body numb, while the patient is conscious or only lightly sedated. General anesthesia involves use of intravenous medications and inhaled  gases to render the patient unconscious and unaware during surgery. The  

The anaesthetic team is attentive to the patient’s vital signs, oxygen saturation, heart rate and blood pressure throughout the procedure to ensure safety. 

Modern Prosthetic Components and Materials 

Today, knee implants are made from biological compatible substances, selected for durability, stability and functionality. These are the femoral and tibial. 

The materials used to construct components are generally cobalt-chromium alloy or titanium alloy, which are highly corrosion- and wear-resistant.  The articulating surfaces are made with advanced polyethylene (UHMWPE) or ceramic materials which offer smooth gliding and excellent wear resistance. 

Over the past few decades, there has been a significant improvement in the design of prosthetics, and in fact, there is a large amount of long-term follow-up data available that shows that they can last many years if they are well aligned and placed. Many of the current prosthetic designs last 15-20 years or more and the longevity is dependent on patient activity level, age, and alignment and fixation of the components. 

There are different types of prostheses available, from the traditional posterior stabilized to constrained and rotating platform prostheses. Dr. Rawat chooses the right design of the prostheses for different patients depending on their anatomy, joint condition, and functional needs.

Benefits of Total Knee Replacement 

The benefits of total knee replacement are well known and significant. There is a dramatic relief of pain for most patients, with around 90-95% of patients saying their knee pain before the surgery is much better or completely gone. The range of motion and knee flexibility will usually improve, and patients can enjoy easier movement. Maintain and achieve levels of ability to bend and straighten that are functional. 

Patients experience markedly improved function and mobility, such as walking longer distances without pain, climbing and descending stairs with less difficulty and/or pain, rising from a sitting position without pain or difficulty, and engaging in low impact activities like swimming, cycling, golf, or walking for exercise. Patients report significant improvement in quality of life including increased  performance in their activities of daily living, increased social and recreational function and an active lifestyle. 

Improved physical health and fitness can result from increased activity levels  after surgery. Psychological advantages are often seen as patients become independent and confident in their mobility. This often can remove or greatly diminish the need for pain medication and other therapies. 

Preparation for Total Knee Replacement 

Adequate preparation significantly improves surgical outcomes and recovery. 

Patients should have a medical clearance exam with their primary care physician to optimize overall health for surgery. If there is any active infection it should be treated prior to surgery. Chronic health conditions, such as blood pressure, diabetes, should be well managed. 

Review medications; adjust blood thinners, and some medications should be discontinued perioperatively. Patients should have optimal physical conditioning, preferably achieved by pre-operative exercise and physical therapy; strong muscles and good flexibility aid in the recovery following surgery. Preparing the mind and educating patients on the expectations after surgery can help minimize anxiety and promote adherence to rehabilitation. 

Postoperative care including home transportation from hospital, home modifications for safety and accessibility in the immediate hospital period and assistance with activities of daily living during the early postoperative period shall be arranged. The team of surgeons gives clear, concise preoperative advice on the need for fasting, taking medicines and what to expect on surgery day. 

Hospital Stay and Admission Process 

Most knee replacement surgery is conducted in an accredited hospital or surgical center that has the necessary facilities and equipment. Admission is usually in the morning of surgery. Pre-op assessment is performed, IVs placed and the patient is moved to the OR. 

With rapidly advancing surgical techniques and early mobilization protocols, the average hospital stay is getting shorter, with many patients discharged 1-2 days after surgery, and some patients 2-3 days after surgery depending on the recovery progress, pain control, range of motion and overall recovery. Before patients can be discharged they need to be capable of ambulating safely with assistive devices, be able to manage pain with oral medication, and be able to independently carry out basic care needs. 

Recovery After Total Knee Replacement 

In the immediate postoperative period (1-2 days following surgery), there is a need for pain control, elevation and icing, early range of motion exercises to prevent stiffness and early mobilization with assistance from Physical Therapist. Patients usually start walking with support from their crutches or walker 24 hours after surgery. 

Early (first 2-6 weeks) recovery emphasis is on progressive range of motion and weight-bearing tolerance, continued pain and swelling management, ability to ambulate independently without assistive devices, perform home exercises, and to return to light activity. During this time the majority of patients move from the use of crutches or walker to a cane and then to walking independently. 

Intermediate recovery phase (6 weeks to 3 months) includes continued progression of range of motion and strength, increasing to more normal activities, a gradual reduction of pain medications, decreasing swelling as tissues heal, and progress with rehabilitation exercises. During this time, many patients can begin to walk for exercise, cycle (stationary) and go swimming. 

Full recovery usually takes 3-6 months, and continued improvement may be achieved for up to a year post surgery. There may be some swelling and some minor discomfort which may last for several months – this is normal and will generally improve with time and continued activity. 

Postoperative Care and Rehabilitation 

Physical therapy is crucial for the best possible outcome after surgery. Movement, which is started between the first and fifth day after surgery, is the part of the physical therapy that is emphasized.

The treatment includes motion exercises, pain and swelling management, early weight bearing and ambulation schedule, activity modification and precautions education. 

These programs are essential; the patients do specific exercises several times a day at home in order to preserve and enhance the range of motion and strength.  Progressive resistance exercises develop strength in the quadriceps and the hamstrings to support the knee, and enhance functional capacity. Walking distance and intensity gradually increased as tolerated. 

Formal physical therapy for 4-6 weeks or more with a physical therapist to work through progressive strengthening, gait training, proprioception/balance and safe progression of activities can be very helpful for many patients. Ice, elevate, and/or medication as necessary for pain and swelling management continue. 

Return to Work and Activities 

The ability to return to work is dependent on the nature of the employment and recovery of the individual. Patients who have sedentary desk jobs may be able to return after 4-6 weeks, patients who have to stand, walk or have physical tasks can take 8-12 weeks or more. Dr. Rawat can make recommendations to work restrictions based on individual needs. 

Walking for exercise is safe for most patients 4-6 weeks after surgery. Swimming and water aerobics can resume after the scar has completely healed (at 3-4 weeks). With low impact activities such as cycling, elliptical exercise, golfing, the activity can generally resume within 8-12 weeks. Running and jumping are usually not recommended, although many patients have returned to walking, cycling, swimming and golf for many years without taking them off their agenda. 

Sexual activity may resume when patient is comfortable and adequate pain control is achieved, which is usually within 4-6 weeks. Patients should know that air travel is considered safe after 4-6 weeks, but that sitting for prolonged periods of time increases the risk of blood clots so they should use the leg exercises they are taught during flights.

Cost and Financial Considerations 

The cost of total knee replacement varies based on facility costs, surgeon fees, anesthesia charges, prosthetic component selection, and individual patient  factors. Patients with private insurance should verify coverage, understand  their deductibles and out-of-pocket maximums, and confirm that Dr. Rawat and the surgical facility are in-network providers when possible. 

Government insurance programs including Medicare and Medicaid typically cover  total knee replacement when medically indicated. Payment plans and financing  options are often available for patients without insurance or those with high  out-of-pocket costs. Dr. Rawat’s office can provide detailed cost estimates and  assist with insurance verification. 

Insurance Coverage and Cashless Facilities 

Total knee replacement is typically covered by major insurance providers when  deemed medically necessary. Many facilities maintain agreements with insurance  companies for cashless treatment, meaning the insurance company pays the  facility directly and the patient is not responsible for out-of-pocket payments  beyond their normal insurance obligations (copays, deductibles, coinsurance). 

Dr. Sanjay Rawat performs knee replacement surgeries at accredited hospitals in  Indore that maintain cashless agreements with major insurance providers.  Patients should verify their specific coverage details with their insurance  provider and Dr. Rawat’s office.
