What is a Knee Replacement Surgery?

Knee replacement surgery, medically known as knee arthroplasty, is a surgical procedure designed to alleviate pain and restore function in severely damaged knee joints. This procedure involves replacing damaged or diseased knee joint surfaces with artificial implants made of metal, plastic, or ceramic materials. 

Here's what the surgery entails:

• Preparation: Before the surgery, patients undergo a thorough evaluation to assess their overall health and readiness for the procedure.
• Anesthesia: During the surgery, patients receive either general anesthesia to induce unconsciousness or regional anesthesia to numb the lower body.
• Incision: The surgeon makes an incision over the knee joint to access the damaged area.
• Reshaping: The damaged bone and cartilage are removed from the knee joint, and the bone surfaces are reshaped to accommodate the artificial implants.
• Implantation: The artificial implants, including metal components for the femur and tibia and a plastic spacer, are securely placed into position.
• Closure: Once the implants are in place, the incision is closed with sutures or staples.

Now, let's explore the various options tailored to individual needs and conditions.

Types of Knee Replacement

Knee replacement surgery offers several variations tailored to meet individual patient needs and address specific conditions. Here's an overview of the types:

Total Knee Replacement (TKR)

This procedure involves replacing the entire knee joint with artificial implants, including the femoral, tibial, and patellar components. It's typically recommended for patients with advanced osteoarthritis or rheumatoid arthritis affecting the entire knee joint.

Partial Knee Replacement (PKR)

In PKR, only the affected portion of the knee joint is replaced with artificial implants. This option is suitable for patients with localized arthritis or damage confined to one area of the knee.

Bilateral Knee Replacement

Bilateral knee replacement involves replacing both knees during a single surgical procedure. It's commonly recommended for patients with bilateral knee arthritis or those seeking simultaneous treatment for both knees.

Revision Knee Replacement

Revision knee replacement is performed to replace a failed or worn-out knee implant from a previous knee replacement surgery. This procedure requires specialized implants and surgical techniques to address complex issues such as bone loss and instability.

Moving forward, let's delve into the crucial role of physical therapy after knee replacement surgery.

2. Progressive Exercise Program

As healing progresses, physical therapists design customized exercise programs tailored to each patient's needs and goals. These programs focus on:

• Gradually increasing the intensity and duration of exercises to improve strength, flexibility, and endurance.
• Incorporating a variety of exercises targeting different muscle groups around the knee joint.
• Implementing functional movements and activities to simulate real-world scenarios and improve functional capacity.
• Monitoring progress closely and adjusting the exercise regimen as needed based on individual response and recovery.

3. Pain Management Strategies

Effective pain management is essential for facilitating rehabilitation and promoting patient comfort throughout the recovery process. Physical therapists employ various strategies to manage pain, including:

• Utilizing modalities such as ice packs, heat therapy, transcutaneous electrical nerve stimulation (TENS), or electrical muscle stimulation (EMS) to alleviate pain and reduce inflammation.
• Teaching relaxation techniques, deep breathing exercises, and guided imagery to help patients manage pain sensations.
• Collaborating with the healthcare team to optimize pain medication management and minimize side effects.
