Your knee is an important part of your body. It is a vital joint that allows you to walk, run, and move freely. However, when pain and injury from different kinds of conditions affect your knee, knee replacement surgery can help you regain your mobility.
What is Knee Replacement Surgery?
Knee replacement surgery is a procedure in which a damaged or worn-out knee joint is replaced with an artificial one. This surgery can be an effective treatment for those suffering from debilitating knee pain and immobility. Ultimately, it offers a chance for patients to reclaim an active lifestyle.
The surgical procedure involves your orthopedic surgeon making an incision at the knee to remove the damaged parts of the joint. From there, artificial components are carefully placed to mimic the shape and function of your natural knee.
A Quick Look at the Anatomy of the Knee
The knee is a sophisticated structure of bones, cartilage, ligaments, and tendons that come together to facilitate movement. It is composed of the upper end of the shin bone (tibia), the kneecap (patella), and the lower end of the thigh bone (femur). Cartilage, a smooth cushioning substance, along with synovial fluid, ensures smooth movement of these bones. Ligaments and tendons provide stability and support.
Different parts of the knee can be affected by various injuries and conditions. Let us learn more about the three types of knee replacement to find what may work best for your situation.
Total Knee Replacement Surgery
Total knee replacement is one type of knee replacement surgery. It involves the complete replacement of the knee joint’s surfaces with artificial components. As its name implies, this surgical procedure involves the entire joint.
In total knee replacement, the ends of both the femur and tibia, along with the underside of the patella, are replaced with prosthetic counterparts. This comprehensive approach ensures a more uniform and extensive restoration of the knee function.
Recovery from a total knee replacement is a journey of gradual progress. Initially, it involves managing postoperative pain, swelling, and starting physical therapy. Patients generally return to everyday activities within 6 to 12 weeks, with continuous improvement over time.
When Do You Need Total Knee Replacement?
This type of knee replacement is particularly beneficial for patients with widespread damage to the knee joint. Some situations where this type of knee replacement may be recommended include:
- Severe arthritis
- Extensive damage to multiple parts of the knee
- Significant pain and stiffness
- Poor response to other treatments
Partial Knee Replacement Surgery
Another type of knee replacement surgery is partial knee replacement (PKR). This is a surgical procedure designed for patients with limited knee arthritis. Unlike total knee replacement, this type of surgery targets only the specific compartment of the knee that is damaged.
The knee has three main compartments, and PKR focuses on the one that is affected—either the medial (inside), lateral (outside), or patellofemoral (front) compartment. This targeted approach is an excellent option for patients whose condition is not widespread. By preserving more of the knee’s natural structure, PKR typically allows for a more natural knee function post-surgery.
One of the appealing aspects of partial knee replacement is the faster recovery time. The pain and discomfort associated with PKR are generally less intense than a total knee replacement, and patients can expect to return to normal activities sooner.
When Do You Need Partial Knee Replacement?
Partial knee replacement may be the best option in these situations:
- Localized arthritis
- Intact major knee ligaments
- Limited pain and disability
- Desire for a less invasive option and more natural knee function
Revision Knee Replacement Surgery
Revision knee replacement surgery, a complex and specialized procedure, is undertaken when an initial knee replacement (either total or partial) wears out. This surgery is more intricate than primary knee replacements due to various factors like bone loss, scar tissue, and the need for specialized implants.
This procedure involves replacing old knee prostheses with new components. It is typically considered when the original implant becomes loose, wears out, or gets infected, causing pain and instability.
The recovery from a revision knee replacement is generally longer and more challenging compared to a primary knee replacement. Due to the complexity of the surgery, patients face an extensive rehabilitation process to recover and regain strength and mobility.
When Do You Need Revision Knee Replacement?
Unlike primary knee replacement surgeries, which are mostly due to arthritis, revision surgery addresses issues related to the longevity and function of the existing artificial knee joint. Revision knee replacement becomes necessary under circumstances such as:
- Implant wear and loosening
- Infection
- Instability or stiffness
- Persistent pain after a previous knee replacement
