Knee replacement surgery can be a life-changing procedure for individuals suffering from chronic knee pain and mobility issues. At Sri Balaji Action Medical Institute, we understand the importance of providing comprehensive information to our patients to ensure they feel confident and empowered throughout their healthcare journey. In this guide, we'll delve into the details of knee replacement surgery, covering everything from the procedure itself to recovery and beyond.
What is Knee Replacement Surgery?
Knee replacement surgery, also known as knee arthroplasty, is a procedure aimed at relieving pain and restoring function in severely diseased or damaged knee joints. It involves removing damaged bone and cartilage from the knee joint and replacing it with artificial implants made of metal alloys, high-grade plastics, and polymers.
Who Needs Knee Replacement Surgery?
Knee replacement surgery is typically recommended for individuals who experience:
- Chronic knee pain that limits daily activities
- Severe knee stiffness and swelling
- Decreased mobility and difficulty walking or climbing stairs
- Failure to find relief from conservative treatments such as medication and physical therapy
It's essential to consult with an orthopedic surgeon to determine if knee replacement surgery is the right option for you based on your specific condition and medical history.
Types of Knee Replacement Surgery
There are several types of knee replacement surgery, including:
Total Knee Replacement (TKR)
In total knee replacement surgery, both the femur (thigh bone) and tibia (shin bone) are replaced with artificial components. The kneecap may also be resurfaced with a plastic component to improve its function.
Partial Knee Replacement (PKR)
Partial knee replacement surgery involves replacing only the damaged part of the knee joint, preserving healthy bone and tissue. This option is suitable for individuals with limited knee arthritis confined to one area of the knee.
Revision Knee Replacement
Revision knee replacement is performed to replace a failed or worn-out knee implant from a previous knee replacement surgery. It's a more complex procedure that requires specialized expertise.
The Knee Replacement Procedure
Preoperative Preparation
Before undergoing knee replacement surgery, your healthcare team will conduct a thorough evaluation, including imaging tests and blood work, to assess your overall health and ensure you're a suitable candidate for the procedure. You may also receive instructions on preoperative exercises and lifestyle modifications to optimize your recovery outcomes.
Surgical Procedure
During the surgery, you'll be placed under general or regional anesthesia to ensure you're comfortable and pain-free throughout the procedure. The surgeon will make an incision over the knee joint and carefully remove damaged bone and cartilage. The artificial implants are then secured in place using specialized surgical techniques.
Postoperative Recovery
After the surgery, you'll spend some time in the recovery room before being transferred to a hospital room for monitoring. Physical therapy will begin shortly after surgery to help regain strength, flexibility, and mobility in the knee joint. Most patients can expect to stay in the hospital for a few days before transitioning to outpatient rehabilitation.
Benefits of Knee Replacement Surgery
Knee replacement surgery offers numerous benefits, including:
- Significant reduction in knee pain
- Improved joint function and mobility
- Enhanced quality of life and ability to perform daily activities
- Long-term durability of artificial implants
Risks and Complications
Like any surgical procedure, knee replacement surgery carries risks and potential complications, including:
- Infection at the surgical site
- Blood clots in the legs or lungs
- Nerve or blood vessel damage
- Dislocation or instability of the knee joint
- Allergic reactions to anesthesia or implant materials
It's crucial to discuss these risks with your healthcare provider and follow all pre- and postoperative instructions to minimize complications.
