What is Knee Replacement ?
Knee replacement, also known as knee arthroplasty, is a surgical procedure in which a damaged or diseased knee joint is replaced with an artificial joint, also known as a prosthesis. The procedure is typically done for patients who have severe knee pain or stiffness that is not responding to other treatments, such as physical therapy or medications.
During knee replacement surgery, the damaged or diseased parts of the knee joint are removed and replaced with a prosthetic joint made of metal, plastic, or a combination of the two. The prosthetic joint is designed to mimic the natural shape and function of the knee joint, allowing the patient to move the knee more easily and with less pain.
Knee replacement is a major surgery that requires general anesthesia and typically involves a hospital stay of several days. After surgery, the patient will need to undergo physical therapy to help regain strength and range of motion in the knee. With proper care and rehabilitation, most patients are able to resume normal activities within a few months of surgery.
Situation to do Knee Replacement
Here are some common reasons why knee replacement surgery may be recommended:
Osteoarthritis: Osteoarthritis is the most common reason for knee replacement surgery. It is a degenerative condition that causes the cartilage in the knee joint to wear down, leading to pain, stiffness, and limited mobility.
Rheumatoid arthritis: Rheumatoid arthritis is an autoimmune condition that can cause joint damage and inflammation, including in the knees. In severe cases, knee replacement surgery may be necessary to alleviate pain and improve function.
Post-traumatic arthritis: This type of arthritis can occur after a knee injury, such as a fracture or ligament tear. Over time, the damage to the knee can lead to arthritis, which may require knee replacement surgery.
Knee deformity: In some cases, a knee deformity such as bowing or severe knock-knees can cause significant pain and disability. Knee replacement surgery may be necessary to correct the deformity and improve function.
Meniscus tears or other injuries: In some cases, a knee injury or meniscus tear can lead to chronic pain and instability that does not improve with other treatments.
Tumors: In rare cases, a tumor in the knee joint may require removal of the joint and replacement with an artificial joint.
If you are experiencing chronic knee pain or other symptoms that are affecting your mobility and quality of life, it’s important to talk to your doctor about your treatment options, including knee replacement surgery.
Precautions to be taken after Knee Replacement Surgery
After knee replacement surgery, there are several precautions you should take to promote healing and prevent complications. Here are some general precautions:
Follow your doctor’s instructions: Your doctor will give you specific instructions on how to care for your knee after surgery, including how much weight to put on your leg, how to manage pain and swelling, and when to start physical therapy.
Keep your incision clean and dry: It’s important to keep your incision site clean and dry to prevent infection. Your doctor may recommend showering instead of taking baths, and you should avoid soaking in water, swimming, or using hot tubs until your incision has fully healed.
Use assistive devices: Your doctor may recommend using crutches, a walker, or a cane to help you move around safely and avoid falls.
Avoid certain movements: You should avoid twisting or pivoting on your knee, and should not cross your legs or sit with your legs bent for extended periods of time. Your doctor may also recommend avoiding high-impact activities such as running and jumping.
Manage pain and swelling: Pain and swelling are common after knee replacement surgery, and your doctor will likely prescribe pain medications and recommend ice and compression to manage these symptoms.
Attend physical therapy: Physical therapy is an important part of the recovery process after knee replacement surgery. Your therapist will help you regain strength, flexibility, and range of motion in your knee, and may recommend exercises to improve balance and prevent falls.
It’s important to follow your doctor’s instructions and attend all scheduled follow-up appointments after knee replacement surgery to ensure proper healing and minimize the risk of complications.
