What Is The Latest Procedure For Knee Replacement

Making The Knee Incision

Could patients avoid knee replacement surgery with new implant?

The surgeon makes an incision across the front of your knee to gain access to the patella, more commonly referred to as the kneecap. In a traditional knee replacement, the incision is usually about 8 to 10 inches long. In minimally invasive knee surgery, the incision is usually about 4 to 6 inches long. The jury is still out as to whether or not the pros of the smaller scar outweigh the cons of a smaller surgical area. Talk to your doctor about which procedure is right for you.

How Do I Get Ready For Total Knee Replacement

Ask your provider how you should plan to get ready for your surgery.

Tell your provider about any medicines you are taking, including:

  • All prescription medicines

  • Over-the-counter medicines such as aspirin or ibuprofen

  • Street drugs

  • Herbs, vitamins, and other supplements

Ask if there are any medicines you should stop taking ahead of time, like blood thinners.

If you smoke, try to quit before your surgery.

If you are overweight, your provider may advise you to try to lose weight before your surgery.

Donât eat or drink after midnight the night before your procedure.

You may want to make some changes to your house, to make your recovery smoother. This includes things like adding a handrail in your shower.

In some cases, your provider might want additional tests before you have your surgery. These might include:

  • X-rays, to get information about your hip

  • MRI, to get more detailed information about your hip

  • Electrocardiogram , to make sure your heart rhythm is normal

Follow any other instructions from your healthcare provider.

When To Seek Emergency Care

Warning signs of a blood clot in the lungs include sudden shortness of breath, chest pain, and coughing. Signs of infection include fever, worsening redness or tenderness of the knee, and pus draining from the surgical wound. If you feel or see any of these symptoms after knee replacement, call your doctor immediately. Call 911 for chest pain or if you are having any trouble breathing.

A Knee Replacement That Could Last A Lifetime

Robotic surgery, cementless implant among advances that could lead to longer-lasting knee replacement

Dr. Geoffrey Westrich of Hospital for Special Surgery says advances in knee replacement surgery have benefited patients.

Newswise Forty-nine-year-old James Benfantes knee pain got so bad he dreaded walking from the train station to his job or even standing in line. Working out in the gym became all but impossible. He decided it was time for knee replacement surgery, and he did what many people do nowadays: he went online to get the latest information.

Mr. Benfante, who lives in Yorktown, New York, says he learned that robotic-assisted surgery enables orthopedic surgeons to perform the procedure with pinpoint accuracy, and this was important to him. The FDA-approved system starts with a CT scan to create a 3D virtual model of the patients unique anatomy. During the procedure, a robotic arm assists surgeons in performing an ultra-precise knee replacement customized for each patient.

Mr. Benfante wanted a joint replacement specialist trained in the use of the robotic system and found Dr. Geoffrey Westrich, director of Research in the Adult Reconstruction and Joint Replacement Service at Hospital for Special Surgery .

With biologic fixation, many joint replacement specialists believe that loosening over time could be less likely. A total knee replacement could potentially last much longer, even for a patients lifetime, Dr. Westrich says.

What Happens During Knee Arthroplasty

The day of surgery, you will receive anesthesia to prevent pain during the operation. You will have either a regional or general anesthetic. Your anesthesia team will decide what type of anesthesia is right for you.

Knee arthroplasty takes about an hour or two. The surgical team will:

  • Make an incision in the knee area.
  • Remove any damaged cartilage and bone.
  • Place the knee implant and position it properly.
  • Secure the implant into place using cement or without cement.
  • Insert a piece of polyethylene that creates a smooth, gliding surface between the metal parts of the implant.
  • Close the incision.

The staff will help you to get up and walk about as quickly as possible. If you’ve had keyhole surgery or are on an enhanced recovery programme, you may be able to walk on the same day as your operation. Generally, you’ll be helped to stand within 12 to 24 hours after your operation.

Walking with a frame or crutches is encouraged. Most people are able to walk independently with sticks after about a week.

During your stay in hospital, a physiotherapist will teach you exercises to help strengthen your knee. You can usually begin these the day after your operation. It’s important to follow the physiotherapist’s advice to avoid complications or dislocation of your new joint.

It’s normal to have initial discomfort while walking and exercising, and your legs and feet may be swollen.

You may be put on a passive motion machine to restore movement in your knee and leg. This support will slowly move your knee while you are in bed. It helps to decrease swelling by keeping your leg raised and helps improve your circulation.

Growing Cartilage In The Lab

There are surgical procedures that use cartilage cells that have been harvested from a patient, cloned and reproduced in a lab, and then reinserted into the patient. However, these cartilage cells can only be inserted into relatively small voids in the cartilage, not to “resurface” a worn out, arthritic joint.

There are possible solutions for patients with a;limited area of cartilage damage, but this is not an arthritis treatment. These cartilage replacement techniques are for patients with limited areas of cartilage damage, often caused by sports or traumatic injuries.

For replacement to succeed, areas of cartilage damage have to be smallnot the widespread damage seen in arthritis.

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.

Are There Potential Complications From Partial Knee Replacement Surgery

Even though partial knee replacement is considered a minimally invasive procedure, there are still risks associated with the surgery. Although rare, blood clots are the most common complication after;surgery. Other complications include infection,implant loosening, fractures and nerve or blood vessel damage. The main disadvantage of a partial knee replacement is the potential need for more surgery in the future. If osteoarthritis progresses to the other compartments of your knee, a total knee replacement revision surgery may be necessary.

In summary, a MAKOplasty type partial knee replacement provides a valuable additional alternative for patients with knee arthritis. It is important to discuss the specific risks associated with MAKOplasty and other treatment options with your orthopaedic surgeon.

Patients Spend Less Time In Hospital Feel Minimal Discomfort Following Surgery

CALGARY Patients undergoing knee replacement surgery are recovering faster and going home sooner as a result of a new approach to this surgical procedure.

Earlier this year, Dr. Rajrishi Sharma became the first orthopedic surgeon in Western Canada to adopt a new protocol for knee replacement surgery in patients with osteoarthritis. Since then, he has used it on 20 patients at the Peter Lougheed Centre; 17 returned home same-day and the other three within 24 hours. None required hospital readmission. Before this approach, patients undergoing this surgery would typically remain in hospital for three to five days.

Knee replacement surgery can be extremely painful and have a lengthy recovery time for patients, says Dr. Sharma. This new protocol helps the patient experience less post-operative pain and have less functional restrictions, which reduces the time it takes them to walk from a few days to just several hours. This significantly impacts a patients post-surgical experience, ultimately helping them recover more quickly. These are still early days weve used this protocol for only nine months but Im pleased the results weve had to date are promising.

I found I even started having pain in my back and other leg because I was compensating so much for the pain in my knee, Thompson recalls.

About 6,000 knee replacement surgeries are performed each year in Alberta.

Is Meniscoplasty Effective

Another of the more common knee replacement surgery alternatives is known as meniscoplasty. Meniscoplasty is also known as keyhole surgery. Basically, with an operation, the doctor will make an incision increase of the affected joint and remove part or all of it. An interesting thing about minimally invasive alternatives to knee replacement surgery is that there are no major complications with this kind of procedure compared to other options.

What Is In A Knee Implant

The damaged knee joint will be replaced with an artificial prosthesis. There are many different types of implants and the decision for the type of prosthesis used will depend on several factors. The knee anatomy, degree of deformity, and stability and quality of the soft tissues will be considered when choosing an implant. Artificial knee implants are made of metal alloys, ceramic, and plastic. Artificial knee implants are continually improved to benefit not just function but also longevity. Modern knee implants can last 20 years or longer.

How The Operation Is Done

Knee replacement surgery is usually performed either under general anaesthetic or under spinal anaesthetic or epidural .

The worn ends of the bones in your knee joint are removed;and replaced with metal and plastic parts which have been measured to fit.

You may have either a total or a partial knee replacement. This will depend on how damaged your knee is. Total knee replacements are the most common.

Read more information about what happens on the day of your operation.

The Technique Is Different From The Typical Down The Front Replacement Technique Because It:

Knee Replacement Surgery
  • Is always performed without a tourniquet, allowing normal blood flow to continue throughout the surgery
  • Preserves other normal structures as well as their function, like the anterior fat pad for kneeling
  • Avoids all the major nerves and blood vessels which minimizes bleeding and aids healing
  • Doesnt require general anesthesia or a breathing tube
  • Uses ultrasound-guided selective nerve blocks with long-acting local anesthesia and IV sedation
  • Uses real-time 3D stereoscopic digital data mapping of the knee
  • Uses computer-assisted navigation for precise ligament balancing, positioning, and alignment
  • Allows for full weight bearing and walking to begin immediately
  • Typically achieves normal range knee motion in two to four weeks

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.

Can You Explain Some Of The Benefits Of This Procedure

One of the biggest benefits of having the procedure done this way is that healthy active people, with painfully worn or arthritic knees which are otherwise structurally sound, can essentially get new durable surfaces in the knee without affecting the structure, and do so without the usual cutting of the muscles and tendon, as is done routinely with a traditional knee replacement. Instead, by approaching the knee from the side under and around the soft tissues, we can perform the knee equivalent putting a crown on a structurally good tooth, instead of replacing the whole structure. You get the new surfaces you need, but keep whats good without doing collateral damage to your underlying structure, bone, muscles, tendons, ligaments, and kneecap. What is still good about your knee remains good, and what is bad get renewed.

Better, less invasive, more precisely sized and aligned, preserving normal structures, put in from the side without cutting any muscle or tendon, and a faster recovery it is truly a game changer, ushering in a new era in knee replacement.
