Indications of knee replacement surgery
Knee replacement surgery is recommended when conservative treatments are no longer effective in relieving severe knee pain and improving mobility. Common indications for knee replacement surgery include:
Other reasons include:
- Osteoarthritis: The most common reason for knee replacement, Osteoarthritis is the degeneration of the joint's cartilage due to wear and tear over time.
- Rheumatoid Arthritis: An autoimmune disorder that triggers inflammation and harm to the lining of the joint, resulting in pain and deformity.
- Post-Traumatic Arthritis: Arthritis that develops after a severe knee injury, such as a fracture or ligament tear.
- Knee Deformities: Severe knee deformities, such as bow-leggedness or knock-knees, that cause pain and impaired function.
- Failure of Conservative Treatments: When non-surgical treatments like medications, physical therapy, and injections no longer provide relief.
- Limited Mobility: Difficulty in walking, climbing stairs, and performing daily activities due to pain & stiffness.
- Chronic Knee Pain: Persistent knee pain that significantly affects the patient's quality of life.
Steps involved in Knee Replacement Surgery
Here are the general steps involved in a knee replacement surgery:
- Preparation: Before the surgery, the patient undergoes a thorough evaluation, including medical history, physical examination, and often imaging tests (such as X-rays or MRI scans). The surgeon discusses the procedure, potential risks, benefits, and expected outcomes with the patient.
- Anesthesia: The patient is given anesthesia to ensure they are comfortable and pain-free during the procedure. This can be either general anesthesia (rendering the patient unconscious) or regional anesthesia (such as spinal or epidural anesthesia) to numb the lower body while the patient remains awake.
- Incision: A vertical or horizontal incision is made over the knee joint. The choice of incision depends on various factors, including the surgeon's preference and the patient's anatomy.
- Exposure: The surgeon carefully moves aside the surrounding tissues, muscles, and ligaments to expose the knee joint.
- Resection of Damaged Bone and Cartilage: The damaged or arthritic portions of the joint's surfaces are removed using specialized tools, such as saws and drills. This includes removing the worn-out cartilage and some bone on the ends of the femur (thigh bone) and tibia (shin bone).
- Implant Placement: Metal and plastic components are used to replace the removed bone and cartilage. These components mimic the natural shape and movement of the knee joint. The femoral component replaces the end of the femur, the tibial component replaces the top of the tibia, and a plastic spacer is placed between them to allow smooth movement.
- Patellar Resurfacing (Optional): In some cases, the undersurface of the kneecap (patella) might be resurfaced with a plastic component to improve joint function and reduce pain.
- Alignment and Testing: The surgeon checks the alignment, stability, and range of motion of the newly implanted joint to ensure proper function.
- Closure: The surgeon stitches or staples the incision closed, often using deep sutures to close the layers of tissue and superficial sutures or staples for the skin.
- Recovery: After surgery, the patient is taken to a recovery area for monitoring as they wake up from anesthesia. Pain management measures are implemented to keep the patient comfortable.
- Postoperative Care: Physical therapy and rehabilitation play a crucial role in the recovery process. The patient starts moving and bearing weight on the knee with the help of a walker or crutches. Physical therapists guide patients through exercises to regain strength, flexibility, and mobility.
- Hospital Stay: Depending on the patient's progress and overall health, the length of hospital stay can vary. In some cases, patients might be able to go home within a few days after surgery.
- Follow-up Care: Regular follow-up appointments with the surgeon are scheduled to monitor the healing process, address any concerns, and adjust the rehabilitation plan as needed.
Who will Treat for Knee Replacement Surgery
A knee replacement surgery, also called as knee arthroplasty, is typically performed by an Orthopedic Surgeon who specializes in joint replacement procedures. Orthopedic surgeons are medical doctors with specialized training in diagnosing, treating, and surgically managing musculoskeletal conditions, including those affecting the bones, joints, ligaments, and tendons.Within the field of orthopedic surgery, there are specialists who focus specifically on joint replacement surgeries, including knee replacements. These specialists are often referred to as joint replacement surgeons, orthopedic surgeons with expertise in arthroplasty, or orthopedic joint surgeons.
Preparing for Knee Replacement Surgery
Preparing for knee replacement surgery is essential to ensure a successful procedure and a smooth recovery. Here are some steps you can take to prepare for your knee replacement surgery:
- Medical Evaluation: Your surgeon will likely order a series of medical tests to assess your overall health and identify any potential risks. These tests may include blood tests, X-rays, Electrocardiogram (ECG), and other relevant screenings.
- Medications: Discuss your current medications with your surgeon. They will provide guidance on which medications you should continue taking leading up to the surgery and which ones you might need to temporarily stop, especially blood-thinning medications or supplements.
- Preoperative Exercises: Engage in preoperative exercises recommended by your surgeon or physical therapist. Strengthening the muscles around your knee joint can help improve your postoperative outcomes and enhance your recovery.
- Nutrition: Maintain a balanced diet rich in nutrients to promote healing. Adequate protein intake can support tissue repair and muscle strength.
- Weight Management: If you are overweight, losing excess weight can reduce stress on your knee joint and potentially improve surgical outcomes. However, make sure to discuss any weight loss plans with your healthcare provider before making changes.
- Smoking Cessation: If you smoke, consider quitting or reducing your smoking before surgery. Smoking can impede healing and increase the risk of complications.
- Home Modifications: Make necessary modifications to your home to ensure a safe and comfortable recovery. Clear pathways, remove tripping hazards, and consider installing grab bars in the bathroom and stair railings if needed.
- Assistive Devices: Obtain any assistive devices recommended by your surgeon or physical therapist, such as crutches, a walker, or a cane, to aid in mobility post-surgery.
- Clothing: Plan to wear comfortable and loose-fitting clothing on the day of the surgery. Choose clothes that are easy to put on and take off, as you might have limited mobility immediately after the surgery.
- Postoperative Care Plans: Discuss your postoperative care plans with your surgeon. Understand the expected recovery timeline, physical therapy requirements, and any restrictions on activities during the healing process.
- Support System: Arrange for someone to help you during your recovery period, especially during the first few days after surgery. Having someone to assist with daily tasks and transportation can be extremely beneficial.
- Communication: Keep lines of communication open with your surgeon and healthcare team. If you have any questions or concerns leading up to the surgery, don't hesitate to ask.
- Hospital Stay: If your surgery requires an overnight hospital stay, pack a bag with essential items, including comfortable clothing, toiletries, and any necessary medications.
- Advance Directives: Consider discussing and preparing advance directives, such as living wills and medical power of attorney, in case unexpected complications arise.
