Minimally Invasive Partial And Total Knee Replacement

Minimally invasive is a term used for any type of surgery that is less invasive than traditional or open surgery. Minimally invasive partial or total knee replacement surgeries are innovative procedures that can be as effective as traditional surgery.

Minimally invasive knee replacements use smaller and fewer incisions around the knee, and have been proven to reduce postoperative pain, minimize trauma to tissue, and quicken recovery time.

The most appropriate candidates for minimally invasive knee replacements have minimal or moderate deformity, maintain a healthy weight, have few pre-existing health conditions and are motivated to participate in the rehabilitation process.

What Is An Artificial Knee And How Does It Stay In Place

Artificial knee implants consist of metal and medical-grade plastic called polyethylene.

There are two ways of attaching the components to the bone. One is to use bone cement, which usually takes about 10 minutes to set. The other is a cement-free approach, in which the components have a porous coating that allows the bone to grow onto it.

In some cases, a surgeon may use both techniques during the same operation.

Any operation done with anesthesia has risks, although it is rare that severe complications result from any type of anesthesia.

The options for TKR include:

  • general anesthesia
  • spinal or epidural
  • a regional nerve block anesthesia

An anesthesia team will decide on the most suitable options for you but most knee replacement surgery is done using a combination of the above.

A New Study Provides New Estimates

In February 2019, two large analyses were published in the medical journal Lancet regarding the longevity of replaced hips and knees, that included nearly 300,000 total knee replacements and more than 200,000 total hip replacements. They found encouraging results:

  • Nearly 60% of hip replacements lasted 25 years, 70% lasted 20 years, and almost 90% lasted 15 years.
  • Total knee replacements lasted even longer: 82% lasted 25 years, 90% lasted 20 years, and 93% lasted 15 years.

These estimates are quite a bit higher than prior ones and may reflect improvements in surgical technique and materials, general medical care around the time of surgery, or more aggressive mobilization and physical therapy that starts right after surgery. The study authors also suggest that these numbers reflect real life patients , rather than a small number from a single medical center.

Some caveats are worth noting:

  • These surgeries were performed in New Zealand, Australia, Denmark, Finland, Norway, and Sweden. The results might be different in the US or other countries.
  • Detailed information was not available regarding which patients were considered eligible for total joint replacement and which were denied surgery because they were considered at high risk for failure or complications. These factors can affect the success of joint replacement surgery.

Misalignment Of The Operated Knee

How Long Does Swelling Last After Knee Replacement Surgery ...

Proper alignment of a knee implant is just as important as its fixation to the bone. For starters, a poorly-aligned implant can irritate or even “poke” the surrounding tissues. This, in turn, can cause stabbing, sharp pain.

An incorrectly-aligned implant can also result in more scar tissue to form. After all, it can “injure” the surrounding tissues, so new tissue has to rescue the damaged ones. As mentioned above, the more scar tissue that forms, the higher your risks of stiffness.

However, one of the worse things that misalignment can cause is implant failure. In this case, your knees can become even more unstable, and it may feel “wiggly” or “jiggly.” If your knee buckles or gives way, the misaligned implant can cause even more injuries.

At the very least, you may feel intense sharp pains.

Considerations That Can Increase The Life Of A Joint Replacement

Staying away from high impact activities

Exercises that are stressful on the joint, such as running and jumping can increase the wear on a joint replacement. Cycling, walking, low resistance weight-lifting and calisthenics, elliptical machines and swimming are all low impact activities that wont cause increased stress on the joint.

Patient Weight

Just as high impact exercise can add stress to a joint replacement, so can excess weight. The closer a patient is able to stay towards a normal weight for their body can increase the longevity of the implant.

Underlying conditions and risk of infection

Patients who have medical conditions such as osteoporosis which can cause fractures may have an increased chance of a failed knee replacement. Procedures done post-surgery or diseases that increase the risk for infection can also cause complications following a total knee replacement surgery.

The future of joint replacement longevity

Although you can expect many knee replacements to last up to 20 years, the younger the patient is at the time of surgery affects the possibility of revision. With new advancements in technology and medical research, the goal is to improve the longevity of these joints to surpass 20 years for future patients. We may be seeing patients at a younger age living out the rest of their lives with the same joint replacement.

Malpositioning Of The Implants

Surgeons make an effort to balance the knee at the time of surgery. This means finding the proper size and alignment of the knee replacement so that the knee joint is not too tight, and not too loose, and so this balancing is the same with the knee straight and bent.

This is precisely why a knee replacement is a difficult procedure, and the art of perfecting this takes many years. Errors in the positioning of an implant may not be apparent on the operating table and only become evident when the recovery is stalled.

Newer patient-specific knee replacements are tailor-made and may reduce the risk of malpositioning.

How Long Does A Total Knee Replacement Last And What Affects Longevity

Improvements in surgical techniques, materials, prosthetic design, and fixation have improved dramatically over time. As a result, this has significantly increased how long a total knee replacement lasts.

Several factors affect how long a knee replacement lasts. These include the patient’s condition, age, body weight, and the surgical implant.

Younger patients often ask how long does a total knee replacement last and will need the implant to last longer than older patients. As a result, patients who have a total knee replacement may need to have a revision done to replace their implant at some point in their lifetime. To maximize how long a total knee replacement lasts, patients should avoid high impact activities, competitive sports, running, high impact aerobics, and heavy manual labor.

Patients who are overweight place a significant amount of impact on their bodies. Maintaining a healthy weight lowers the amount of stress placed on the new total knee joint. Avoiding complications will also improve how long a total knee replacement lasts.

What Happens During Knee Replacement Surgery

Knee replacement surgery is also called knee arthroplasty. Patients suffering from severe arthritis choose this procedure to relieve pain and improve mobility. As you age, the cartilage in your joints deteriorates. As a result, bone begins rubbing on bone, causing severe pain.

This pain can affect one or both knees. If you’re suffering from bilateral knee pain, you’ll need to weigh the pros and cons of double knee replacement. These include the cost and risk of complications. They also include the length and logistics of your recovery.

Whether you opt for a single or double knee replacement, however, the procedure remains the same. Your doctor will remove worn-out cartilage and bone from your joint. She’ll then replace the worn-out tissue with a new joint made of synthetic materials.

Some knee implants use all metal or all ceramic. Others combine metal with plastic or ceramic with plastic. The most common type of implant uses a combination of metal alloys, like cobalt chrome and titanium, and durable plastics.
