Knee Replacement Surgery: Procedure, Types, and Risks

Knee replacement surgery, also known as knee arthroplasty, is a medical procedure that involves the removal of damaged or diseased parts of the knee joint and replacing them with artificial components, usually made of metal, plastic, or ceramic. This surgery is typically performed to relieve pain and improve function in individuals suffering from severe knee conditions,

Osteoarthritis: A degenerative joint disease that leads to the wear and tear of cartilage, causing pain and stiffness.

Rheumatoid Arthritis: An autoimmune condition that causes inflammation in the joints, leading to pain and deformity.

Post-traumatic Arthritis: Arthritis that develops after an injury or trauma to the knee.

Other knee disorders: Such as bone deformities or avascular necrosis.

Types of Knee Replacement Surgery:

Total Knee Replacement: Involves replacing the entire knee joint with artificial components.

Partial Knee Replacement: Involves replacing only a portion of the knee joint when damage is limited to a specific area.

Kneecap Replacement: Involves replacing the undersurface of the kneecap (patella).

Procedure:

Preparation: Patients typically undergo preoperative evaluations, including medical history assessments, physical exams, and imaging studies.

Anesthesia: The surgery can be done under general or regional anesthesia, depending on the patient's condition and the surgeon's recommendation.

Incision: The surgeon makes an incision over the knee to access the joint.

Removal of Damaged Tissue: Damaged bone and cartilage are removed.

Placement of Prosthetics: The artificial components are then fitted and attached to the remaining bone.

Closure: The incision is closed with stitches or staples.

Recovery:

After surgery, patients usually spend some time in the hospital for monitoring and rehabilitation. Physical therapy is a crucial part of recovery, helping patients regain strength and mobility. Recovery time can vary, but many individuals can resume everyday activities within a few months.

Risks:

Like any surgery, knee replacement carries risks, including infection, blood clots, nerve damage, and complications from anesthesia. Long-term risks include wear and tear on the artificial joint, which may require revision surgery later.

Overall, knee replacement surgery can significantly improve the quality of life for individuals suffering from chronic knee pain and mobility issues. It is essential for patients to discuss their specific conditions and treatment options with their healthcare providers to make informed decisions.

What are the different types of knee replacement surgery?

Knee replacement surgery, also known as arthroplasty, is performed to relieve pain and restore function to the knee joint. There are several types of knee replacement surgeries, depending on the extent of the damage to the knee and the specific needs of the patient.

 

Total Knee Replacement (TKR): This is the most common type of knee replacement surgery. In a total knee replacement, the damaged cartilage and bone from the surface of the knee joint are removed and replaced with artificial components (prosthetics) on both the femur (thigh bone) and tibia (shin bone). In some cases, the patella (kneecap) is also resurfaced.

 

Partial Knee Replacement (PKR): Also known as unicompartmental knee arthroplasty, this procedure involves replacing only the damaged part of the knee joint. This type of surgery is an option for patients with osteoarthritis limited to one compartment of the knee. The recovery time is generally quicker than for a total knee replacement.

Revision Knee Replacement: This type is performed when a previously implanted knee prosthesis fails or becomes damaged, or when there is an infection. Revision surgery involves removing the old implant and replacing it with a new one, which may require more complex surgical techniques.

Bilateral Knee Replacement - This can refer to either simultaneous or staged (sequential) knee replacements for patients who have significant issues in both knees. Simultaneous bilateral knee replacement involves replacing both knees during a single surgery, while staged bilateral knee replacement involves performing one knee surgery followed by the other after a period of recovery.

Custom or Patient-Specific Knee Replacement: This type uses advanced imaging technology and 3D printing to create a customized implant for the patient. This approach aims to achieve a better fit and alignment for the knee, potentially improving outcomes.

Computer-Assisted Knee Surgery (CAK): While not a type of replacement itself, computer-assisted surgery utilizes technology to aid surgeons in planning and performing the surgery with greater precision. 

Robotic-Assisted Knee Replacement: Similar to computer-assisted surgery, this technique uses robotic systems to assist the surgeon in implanting the knee prosthesis with enhanced accuracy.

Resurfacing Arthroplasty: This is a less common technique that involves replacing only the surface of the knee joint without removing large sections of bone. This is generally used for younger, more active patients as it preserves more bone.

The choice of procedure depends on factors such as the patient's age, activity level, severity of knee damage, overall health, and the specific recommendations of the orthopedic surgeon. Always consult with a healthcare professional for a personalized treatment plan.

Best Knee Replacement Hospital in Lucknow – Wellsun Medicity

 What is Knee Replacement Surgery?

Knee replacement surgery, also known as knee arthroplasty, is a medical procedure performed to replace a damaged or worn-out knee joint with an artificial implant. It is one of the most common orthopedic surgeries recommended for people who suffer from severe knee pain, stiffness, or mobility issues that do not improve with medicines, physiotherapy, or lifestyle changes.

This surgery is often suggested for patients with advanced arthritis, severe joint injuries, or degenerative diseases that affect daily activities like walking, climbing stairs, or even standing.

Why is Knee Replacement Needed?

The most common reason for knee replacement is osteoarthritis, a condition where the protective cartilage in the knee joint wears down. Other reasons include:

·         Rheumatoid arthritis – chronic inflammation of the joints

·         Post-traumatic arthritis – caused by a previous knee injury

·         Bone deformities – misaligned or bowed legs

·         Severe knee injuries or fractures

When knee pain becomes constant and restricts basic movements, knee replacement surgery can restore mobility and improve quality of life.

Types of Knee Replacement Surgery

• ·        Total Knee Replacement (TKR):
•       The entire knee joint is replaced with a prosthetic implant.
• ·         Partial Knee Replacement (PKR):

Only the damaged part of the knee is replaced, keeping healthy parts intact.

·         Revision Knee Replacement:

A second surgery done when the initial implant wears out or gets damaged.

Procedure in Brief

The surgery usually takes 1–2 hours under anesthesia.

The damaged cartilage and bone are carefully removed.

A prosthetic knee implant made of metal, plastic, or ceramic is placed to mimic the natural movement of the knee.

The patient is shifted to recovery and may start physiotherapy within 24–48 hours.

Benefits of Knee Replacement Surgery

·         Relieves chronic knee pain

·         Improves mobility and flexibility

·         Allows the patient to walk, climb stairs, and do daily tasks easily

·         Enhances quality of life and independence

Recovery and Care

Hospital stay is usually 3–5 days.

Most people return to normal activities within 6–8 weeks.

Regular physiotherapy is crucial for a successful recovery.

Avoid high-impact activities like running or jumping initially.

Conclusion

Knee replacement surgery is a safe and effective solution for people suffering from severe knee problems. At Wellsun Medicity, Lucknow, expert orthopedic surgeons use advanced techniques and high-quality implants to ensure faster recovery and long-term results.

Knee Replacement Surgery: Overview & Recovery Process-wellsun medicity hospital

 

Knee Replacement Surgery: Overview & Recovery Process

Knee surgery encompasses various surgical procedures aimed at addressing knee joint issues, such as injuries, arthritis, or degenerative conditions. The most common types include knee replacement (total or partial), arthroscopy (a minimally invasive procedure for diagnosing and treating joint problems), and ligament reconstruction (such as ACL reconstruction). During these procedures, surgeons may remove damaged cartilage, realign bones, or replace parts of the joint to alleviate pain and restore function. Recovery typically involves physical therapy, pain management, and gradual return to activities, with the goal of enhancing mobility and improving quality of life.

Knee Replacement Surgery.

Knee replacement surgery, also known as knee arthroplasty, is a surgical procedure, in which damaged or worn surfaces of the knee joint are replaced with artificial components,

often made of metal and plastic. This surgery is typically performed to relieve pain, restore function, and improve quality of life in individuals with severe knee arthritis, injury, or degeneration that has not responded to conservative treatments. The surgery can be partial, replacing only one compartment of the knee, or total, replacing the entire joint. Following surgery, patients usually undergo rehabilitation to regain strength and mobility.

Why is Knee Replacement Performed?

Knee replacement surgery is performed for various reasons:

Pain Relief: When severe knee pain persists despite conservative treatments like medications, physical therapy, or assistive devices, it can greatly hinders daily activities. The goal of knee replacement is to alleviate chronic pain and enhance overall function.

Improved Mobility: A compromised knee joint can restrict movement, making walking, climbing stairs, and participating in daily activities challenging. This surgery aims to restore mobility and improve the ability to perform everyday tasks.

Joint Stability: Knee replacement can offer stability and support in cases of knee joint instability caused by ligament damage or severe arthritis.

Correction of Deformities: This surgery can correct deformities such as bowed legs or knock knees, helping to restore proper alignment and function.

Recovery Process

Recovery varies by procedure but often includes physical therapy to enhance strength and range of motion, with many patients experiencing significant improvement in quality of life post-surgery. 

More about Knee Replacement Surgery

Surgical Technique: Knee replacement surgery involves removing damaged joint surfaces and replacing them with artificial implants made of metal, plastic, or a combination of both. The surgery can be categorized as a total knee replacement, which addresses all three compartments of the knee, or a partial knee replacement, which focuses on a specific compartment.

Anesthesia: This procedure can be performed under general anesthesia, regional anesthesia (such as spinal or epidural), or a combination of local anesthesia and sedation. The choice of anesthesia is influenced by various factors, including patient preference and the surgeon’s advice.

Recovery and Rehabilitation: After surgery, you'll spend time in a recovery area before moving to a hospital room. Physical therapy and pain management techniques will begin to facilitate healing, restore strength, and improve range of motion. The length of your hospital stay and rehabilitation period will depend on individual circumstances.

Long-Term Outcomes: Knee replacement surgery generally boasts a high success rate for pain relief and functional improvement. Most patients report a significant decrease in knee pain, enhanced mobility, and an overall better quality of life.

Type of Knee Replacement:

1.Unicompartmental Knee Replacement (UKR): This procedure focuses on replacing one compartment of the knee (either the medial or lateral compartment), typically when arthritis is localized to just that area.

 2.Total Knee Replacement (TKR): In a cruciate-retaining total knee replacement, the entire knee joint is replaced, and the PCL is preserved, which aims to maintain the knee's natural kinematics and stability during movement. This type is often chosen for patients who have intact PCLs and do not have severe deformities or arthritis that would necessitate its removal.

3.which includes a cam and post mechanism that helps stabilize the knee during movement.

4.Revision Knee Replacement: When a previous knee replacement fails, a revision surgery may use a posterior-stabilized component for improved stability.
