Procedure

Procedure for Knee Replacement Surgery

Knee replacement surgery, also known as knee arthroplasty, involves replacing a damaged or worn-out knee joint with an artificial implant to relieve pain and improve mobility. Here’s a step-by-step breakdown of the procedure:

1. Anesthesia Administration

• Type of Anesthesia: The patient is administered general anesthesia (to be fully unconscious) or regional anesthesia (spinal or epidural), which numbs the lower body while the patient remains awake but sedated.
• Monitoring: The anesthesiologist monitors vital signs throughout the procedure to ensure the patient’s safety.

2. Preparing the Knee

• Incision: The surgeon makes an incision, typically about 6-10 inches long, over the knee to access the joint. For minimally invasive techniques, the incision may be smaller.
• Exposing the Joint: The surgeon moves the kneecap aside and cuts away the damaged joint surfaces.

3. Removing Damaged Bone and Cartilage

• Bone and Cartilage Removal: The damaged portions of the femur (thigh bone) and tibia (shin bone), as well as the undersurface of the patella (kneecap), are removed.
• Shaping the Bones: The ends of the femur and tibia are reshaped to fit the prosthetic components securely.

4. Implant Placement

• Fitting the Prosthesis: The metal components are positioned on the prepared ends of the femur and tibia. These may be cemented into place or fit without cement to allow natural bone growth to secure them.
• Plastic Spacer: A high-grade polyethylene spacer is placed between the metal components to ensure smooth joint movement and reduce friction.
• Patella Replacement: If needed, the undersurface of the kneecap is also fitted with a plastic component for better movement.

5. Alignment and Stability Check

• Joint Alignment: The surgeon tests the knee’s alignment and stability by moving the leg through its range of motion.
• Adjustments: Any necessary adjustments are made to ensure proper alignment and function of the knee joint.

6. Closing the Incision

• Layered Closure: The deeper layers of tissue are stitched together with dissolvable sutures, and the skin is closed using staples, sutures, or surgical glue.
• Dressing and Bandaging: The knee is cleaned and covered with a sterile dressing to protect the incision site.

7. Post-Operative Care and Recovery

• Recovery Room: The patient is moved to the recovery room for monitoring as the anesthesia wears off. Vital signs are continuously checked.
• Pain Management: Medications are provided to manage pain, reduce swelling, and prevent blood clots.
• Early Mobilization: Physical therapists assist the patient in beginning to move the leg and walking with support as soon as possible, often within the first 24 hours post-surgery.

Types of Knee Replacement Techniques

• Total Knee Replacement (TKR): Both sides of the knee joint are replaced. This is the most common type of knee replacement surgery.
• Partial Knee Replacement (PKR): Only one side of the knee is replaced, suitable for patients with damage limited to a specific part of the knee.
• Minimally Invasive Knee Replacement: Involves smaller incisions and less disruption to surrounding muscles, potentially leading to a quicker recovery.

Duration of the Procedure

• Surgical Time: The entire procedure typically takes 1-2 hours, depending on the complexity of the surgery and the technique used.

Conclusion

Knee replacement surgery is a well-established and highly effective procedure that can relieve pain and restore function for patients with severe knee damage. The process involves careful preparation, precise surgical technique, and thorough post-operative care to ensure the best outcomes.
