Which Implant Is Best For Knee Replacement

How Long Should I Ice My Knee

Implants may serve as viable substitute for knee replacements

You should ice your knee for up to twenty minutes. You can damage the tissues around your knee or even give yourself frostbite if you ice your knee to long. Moving the ice pack around can help ensure your skin tissues will heal without added damage.

Rotating ice packs and periods of icing can help bring down swelling and inflammation gradually. Allowing time between icing can help the area to warm and encourage your knee to start healing. Repeatedly icing your knee can give your knee plenty of time to start healing.

Repeat icing will help reduce the sensitivity of the knee, and you should consistently ice it for at least forty-eight hours after injury to reduce the swelling. Any wrap you use to hold the ice on the injury should fit your knee securely while allowing air and blood to flow.

What Happens During Surgery

The surgeon will make an incision in the knee to access the joint. Next, they will remove the damaged parts of the joint. The bones will be resurfaced to better accommodate the knee implant. Cement will be used to attach the implant prosthesis to the bone. A plastic spacer will be placed between the metal femur and tibia components for smooth gliding movement. Lastly, the surgeon will reposition the kneecap in front of the knee and close the incision.

Can You Wait Too Long To Have Knee Replacement

Undergoing joint replacement too early is not ideal as the artificial joints may wear out after 10 to 20 years, thus requiring a second surgery. On the other hand, waiting until end-stage arthritis or until you cannot handle the pain anymore is also less than ideal as the benefits of the surgery may be limited.

Benefits Of Cemented Implants

Cemented knee implants have been used for years, so we know that they can be effective in the long term. On average, a cemented implant will last 10 to 20 years or more before it needs to be replaced. The cement dries very quickly, so the implant is securely in place when the surgery is complete.

Cemented implants may be a better option for patients who have poor-quality bone due to conditions like osteoporosis for these patients, bone growth may not be sufficient enough to hold the implant in place. Cemented implants are often recommended for patients who are older, overweight, and less active, as well.

What Is Recovery Like

A knee replacement can be performed using a minimally invasive technique, which allows for a faster recovery, as well as less scarring and pain. Patients recover at different rates, but knee replacement patients should dedicate several months for recovery. The doctor will provide detailed instructions after the procedure on how to take care of the knee and improve recovery.

For the first few weeks, the patient will need some assistance. Making modifications to the home can help during recovery. A physical therapy rehabilitation program will help with regaining muscle strength and range of motion. Patients can meet with a physical therapist as soon as the day after surgery.

Many patients are able to return to light office work in just three to six weeks after the surgery and can drive again a month after. To ensure you have a successful procedure, choose a highly experienced orthopaedic surgeon for your total knee replacement.

Types Of Implants For Knee Replacement Surgery

While there are several types of knee implants, all of them have some things in common.

Firstly, all implants comprise an element which attaches one of the two bones of the lower leg to the thighbone and one that attaches to the tibia. An implant may or may not have a patellar component that functions precisely like the kneecap.

Secondly, all knee implants are made of bio-compatible content and made relatively lightweight to adhere to the bone with ease.

Posterior Cruciate Ligament Substituting

Knee Replacement Surgery: Implants

This design replaces ligament with plastic components. It is recommended primarily for patients with severely damaged knees or weak ligaments. Also used in revision surgery.

It is indicated for patients with severe knee deformities or who have had previous knee replacement surgery or have had a knee cap removed.

The PLC substituting design has a tall post attached to the tibia which fits into a deep box attached to the femur. The two are not connected with any kind of hinge joint. A polyethylene bearing attaches to the tibial component.

A 2016 study of the PLC substituting design found that 88.5 percent of PLC substituting implants used in initial knee replacement surgery survived 10 years. For revision surgery, the 10 year survival rate was 75.8 percent if the revision surgery was due to some cause other than infection, and 54.6 percent if revision was due to infection.

What Is Genicular Artery Embolization

Abnormal blood vessel formation, also known as angiogenesis, is one of the causes of knee pain in osteoarthritis patients. Angiogenesis is a key step in the initiation and maintenance of inflammation in the joint capsule. Abnormal vessels that breach into avascular cartilage in the knee is a hallmark of osteoarthritis, so much so that it is one of the diagnostic features of the disease.

GAE is an interventional radiology treatment that can relieve osteoarthritis pain by treating the offending abnormal blood vessels. The procedure blocks the abnormal blood vessels. Doing this reduces inflammation and its resultant pain.

An interventional radiologist performs the procedure. An IR is trained to perform minimally invasive vascular procedures to treat multiple conditions. They treat their patients using procedures such as angioplasty and embolization .

An IR is a medical doctor that has obtained at least six additional years of specialized training in radiology and interventional radiology.

What Are We Replacing During A Complete Knee Replacement Surgery

The major components which are replaced in a complete knee replacement surgery are as follows :

  • Femoral component: This is the part that attaches to the thigh bone. It is the largest component. It has a curvy shape.
  • Spacer: A spacer is fitted in between the femoral and tibial component. The spacer provides flexibility to the knee joint and helps in bending and flexing the knee.
  • Tibial component: This is a flat component which replaces the top part of the shin bone. It has a groove which allows the movement of kneecap up and down on the bending and straightening of the knee joint.
  • Patellar component: Required only on a case to case basis, it is a dome shaped component which replaces the kneecap.

How Does Partial Knee Replacement Differ From Total Knee Replacement

Most arthroplasties target the entire knee joint, an operation called a total knee replacement. But some people choose to have a partial knee replacement.

To understand the difference, it helps to know the knees compartments, or sections. It has three:

  • Inside .
  • Outside .
  • Under the kneecap .

The partial approach fixes a single section. So healthcare providers call it unicompartmental replacement. A total knee replacement addresses all three sections. Generally, only younger adults with symptoms in one knee section benefit from partial replacement.

What Are The Precautions One Must Take Before And After The Surgery

The precautionary measures one must take before and after undergoing a Knee Replacement Surgery are:

Before the Surgery:

  • Avoid taking part in exhaustive physical activities
  • Abstain from smoking and drinking
  • The toilet seat of the patient must be high
  • Take all the medicines prescribed by the doctor religiously
  • A patient must mobilise as must as possible without causing any discomfort
  • Do not bend the knees unnecessarily
  • Avoid climbing stairs. If possible shift the room of the patient to ground floor
  • Avoid bathing with cold water as it increases the pain
  • Eat a healthy and nutritious diet as it will help to strengthen the body to cope up with post-surgical trauma
  • One can also opt for physiotherapy as it helps to subside the swelling and inflammation

Will I Need Any Treatments After Knee Replacement

Your healthcare team will prescribe medications to help you manage pain after surgery, such as:

  • Acetaminophen.

To prevent blood clots and control swelling, your healthcare team might also recommend:

  • Blood thinners, such as aspirin or injectable Enoxaparin based on individual risk of blood clot formation.
  • Compression devices, usually used while hospitalized. These are mechanical devises which provide intermittent compression.
  • Special support hose.

Your team will ask you to move your foot and ankle around frequently to maintain blood flow at home. Theyll also show you special exercises to help strengthen your knee and restore motion. Exercises are very important to the success of your knee replacement. Initially, physical therapy will be in the home. Arrangements for this in home PT are made at the time of discharge from the hospital.

What Are The Best Materials For Joint Replacement

Posted on:

Are you considering a joint replacement surgery? What are the best materials for the surfaces that contact one another? These are called the bearing surfaces. Lets look at the benefits of different materials to understand the proposed procedure. Knowing your options can make you feel less anxious about the surgery and what to expect for the life of your implant. The materials used in the implant typically depend upon various factors, including:

  • Patient age
  • Surgeon preference
  • Particular deformities/abnormalities of the hip or knee

Not all implants are options for every patient. Here is a brief description of some of the most commonly used implants:

Ceramic on Plastic – This type of implant uses metal parts that fit within the bone, but the bearing surface for the ball or head is made of ceramic material. The socket bearing or the cup is made of a special plastic called polyethylene. Ceramic head implants are designed to be the most resistant to wear. Early designs had the risk of breaking. The newer designs are much stronger and it is almost unheard of to have the newer ceramic femoral heads break. Ceramic heads are very hard and very smooth. As a result, they cause less wearing of the polyethylene. People who are sensitive to the nickel used in metal implants might be a good fit for the ceramic type. We use ceramic on polyethylene in the majority of total hip replacements.

Understanding Knee Replacement Surgery

First-ever surgery tests implant device to prevent knee replacements

A joint replacement surgeon usually performs knee replacement surgery, and it involves removing the damaged knee joint and replacing it with prosthetics. Once an orthopaedic physician diagnoses the problem, they can tell you whether you need a partial or complete replacement.

Knee replacement is a safe surgical process and has a success rate of 97%. We provide customised implants, stay technologically up-to-date, and with experienced surgeons like Dr. Mir Jawad Zar Khan, we guarantee a better quality of life post replacement surgery. With knee replacement surgery, you can

  • Regain the mobility of the knee joint
  • Get rid of knee pain and stiff joints
  • Restore the lost functioning of the knee
  • Enjoy better joint alignment
  • Improved quality of life

The first question patients often ask is who needs a replacement is how long do these implants last? So depending on your style of work, these implants usually last from 15-20 years for all ages. They are manufactured with plastic or metal that resembles the joint. So the choice of implant will affect the total knee replacement cost in Hyderabad.

Cobalt Chromium Alloys Implant

The most frequently used metal for knee implants is the cobalt chromium alloy. It is a tough, corrosion resistant, and biocompatible metal.

  • Pros of Cobalt Chromium Alloys Implant
  • It is corrosion resistant
  • The metal is biodegradable
  • Cons of Cobalt Chromium Alloys Implant
  • Joint movement may lead to the release of metal ions in the body, which may cause allergic reactions

What Are The Risks Of Total Knee Replacement

Most people do very well with their minimally invasive total knee replacement. But as with any surgery, the procedure does carry some fairly rare risks. Possible complications of the surgery include:

  • Infection

  • Loosening of the components of the knee

  • Limited motion of the knee

There is also a very slight risk that the procedure might not relieve your pain. Your own risk of complications may vary according to your age and your other medical conditions. Ask your provider about the risks that most apply to you.

Pre-Operative Education

Johns Hopkins offers in-person educational sessions to help you prepare for knee replacement surgery. During your class, we’ll review important aspects of your care and what to expect before and after surgery. You will be able to ask questions and meet many of the staff who will be caring for you in the hospital.

No 7 A Fresh Pair Of Shoes

If youre like me, maybe you have a pair of shoes that you love. Maybe its the look, or maybe their comfortable so you keep them clean and looking like new.

Most people dont realize it but shoes wear down over time. We tend to get comfortable with our shoes plus they can be a considerable investment .

During your rehabilitation, you should be walking and doing physical therapy. Dont take my word for it. According to Livestrong, running shoes should be replaced every 300-500 miles. Of course you wont be running but even if you walk, youll reach 300 miles in no time at all.

For your TKR recovery choose a pair of shoes that are for exercise these can be worn around the house as well. We like a good pair of Nike Air Max because of the extra air cushion in the heel.

The Role Of The Patients Body Frame In Knee Replacement Implants

Orthopaedic surgeons have reported that there are several anatomical differences between the body frames of patients who need knee replacement implants. The patients body structure plays an integral role in deciding the right type of implant. As such, surgeons cannot adopt the “one size fits all” approach when it comes to knee replacement surgeries. Instead, they have to modify the knee implant to suit the patient’s gender, ethnicity, and body frame, thereby ensuring optimal performance.

Meril’s FREEDOM ® Total Knee System is an optimised sizing matrix, designed to cater to the requirements of the global population, with varying requirements. Developed using advanced design engineering technologies and extensive clinical experience, this implant addresses the anatomical, physiological and lifestyle needs of today’s patients. The implant enables patients to achieve optimal high-exion motion and requires minimum bone cutting.

What Can I Expect At Hss

Hospital for Special Surgery has been at the forefront of modern knee replacement since the operation was first introduced in the late 1960s. We have led the field ever since in a number of ways:

  • : HSS has been ranked the No. 1 hospital for orthopedics by U.S. News & World Report for 11 years straight.
  • Along with high rankings in patient satisfaction, HSS performs the most knee replacements with the lowest reported infection rates in the United States.
  • Research and advancement: Smaller incisions, new implant materials and design, and sophisticated instrumentation have been â and continue to be â the areas of expertise of the hip and knee replacement surgeons of the HSS .
  • HSS routinely uses the latest surgical techniques and technology, such as robotic-assisted and computer-assisted surgery.
  • : Isolating the anesthesia to a particular body area helps avoid the potential problems that may accompany a general anesthetic. These techniques have been developed and refined by the HSS . Learn more about

How Is A Total Knee Replacement Performed

First, the orthopedic surgeon makes an incision in the knee and moves the patella to the side. If are any bone spurs are present, as sometimes occurs in osteoarthritis, they will be removed.

Next, the two menisci between the femur and tibia are removed, as are the anterior cruciate ligament and, in some cases, the posterior cruciate ligament . In some types of knee replacement, the PCL is retained.

During the main phase of the operation, the surgeon cuts and remove cartilage and some bone from the upper part of the tibia and lower sections of the femur. The femoral sections removed are two knobby protuberances called the femoral condyles. The tibia and femur are then be capped with metal implants to create new surfaces for the joint. The surface of the femoral component mimics the shape of the original femoral condyles. If the kneecap has also degraded, the surface on its underside may also be cut away and replaced with a polyethylene implant.

Finally, the various layers of tissue are repaired with dissolvable sutures and the skin incision is closed with sutures or surgical staples. A bandage will be wrapped around the knee and the patient is be taken to recovery.
