I think I may need a Knee Replacement! What is a Knee Replacement?

What happens during a knee replacement?

During a knee replacement surgery, the surgeon will remove the damaged parts of the knee joint and replace them with artificial components made of metal, plastic, or ceramic. This is typically done under general anesthesia and takes a few hours to complete.

Here are the basic steps involved in a knee replacement surgery:

• Incision: The surgeon will make an incision in the front of the knee to access the joint.

• Reshaping of the bone: The surgeon will remove the damaged parts of the thigh bone (femur), shin bone (tibia), and kneecap (patella) and reshape them to fit the new artificial components.

• Implantation of the artificial components: The surgeon will attach the artificial components to the reshaped bone using a special cement or another material.

• Testing of the new joint: The surgeon will test the movement and stability of the new joint to ensure it is functioning properly.

• Closure: The surgeon will close the incision with sutures or staples and apply a bandage.

After the surgery, patients will typically stay in the hospital for a few days for monitoring and rehabilitation. They will also need to undergo physical therapy to regain strength and mobility in the knee joint.

What Exercises are best for knee replacement?

After knee replacement surgery, it is important to start exercising as soon as possible to improve knee strength, flexibility, and mobility. However, it is also important to follow your doctor's or physical therapist's instructions and avoid overdoing it. Here are some exercises that are commonly recommended for people who have had knee replacement surgery:

• Quadriceps sets: Tighten the muscles on the top of your thigh and hold for 5 to 10 seconds. Repeat for 10 to 15 repetitions.

• Straight leg raises: Lie on your back with your surgical leg straight and slowly lift your leg off the ground, keeping your knee straight. Hold for 5 to 10 seconds, and then slowly lower your leg. Repeat for 10 to 15 repetitions.

• Hamstring sets: Sit with your leg straight and lift your heel off the ground, pulling your toes towards you. Hold for 5 to 10 seconds and repeat for 10 to 15 repetitions.

• Knee bends: Sit on the edge of a chair with your feet flat on the ground. Slowly bend your surgical knee, sliding your foot back until your knee is at a 90-degree angle. Hold for 5 to 10 seconds, and then straighten your leg. Repeat for 10 to 15 repetitions.

• Stationary biking: Start with a few minutes of low resistance and gradually increase the time and resistance as your knee heals.

Remember to always consult with your doctor or physical therapist before starting any exercise program after knee replacement surgery. They can help tailor a program that is appropriate for your specific needs and recovery progress.

How can Occupational Therapy benefit someone with a knee replacement?

Occupational therapy can be highly beneficial for someone who has had a knee replacement. Occupational therapy focuses on helping individuals to regain their independence and ability to perform activities of daily living (ADLs) and instrumental activities of daily living (IADLs) after an injury or surgery. Here are some of the specific ways that occupational therapy can benefit someone who has had a knee replacement:

• Improving ADLs: Occupational therapy can help individuals with knee replacements to relearn how to perform basic activities of daily living, such as dressing, bathing, and grooming.

• Enhancing IADLs: Occupational therapy can help individuals with knee replacements to relearn how to perform more complex activities of daily living, such as cooking, cleaning, and grocery shopping.

• Modifying the home environment: Occupational therapy can help individuals with knee replacements to modify their home environment to make it safer and more accessible. This may include installing grab bars in the bathroom or using adaptive equipment to make it easier to perform daily tasks.

• Providing education and support: Occupational therapists can provide education and support to individuals with knee replacements, including information on pain management, joint protection, and energy conservation.

• Developing a customized treatment plan: Occupational therapy can help to develop a customized treatment plan that takes into account the individual's unique needs and goals, which can help to optimize their recovery.

Overall, occupational therapy can be an important part of the recovery process after a knee replacement surgery. By working with an occupational therapist, someone who has had a knee replacement can improve their ability to perform daily tasks and regain their independence and quality of life.

How long is the recovery for a knee replacement?

The recovery period for a knee replacement surgery can vary depending on factors such as age, overall health, and the extent of the surgery. However, in general, the recovery period for a knee replacement surgery is about 3-6 months, with most people being able to return to normal activities by 6 months after surgery. Here is a general timeline of the recovery process:

• Hospitalization: Most people stay in the hospital for 2-3 days after a knee replacement surgery, during which time they receive pain management and physical therapy.

• Rehabilitation: Rehabilitation typically begins immediately after surgery, with physical therapy focused on reducing pain and swelling, restoring range of motion, and improving strength and mobility. Rehabilitation typically continues for several weeks to several months after surgery.

• Return to normal activities: Most people are able to return to light activities such as walking and light household chores within a few weeks after surgery. However, it may take several months before they are able to return to more strenuous activities such as running or sports.

• Long-term recovery: It may take up to a year for the knee to fully heal after a knee replacement surgery, and some people may experience continued improvement in their mobility and function even after that.

It is important to note that everyone's recovery process is different, and it is important to follow the advice of your doctor and physical therapist during the recovery process. With proper care and rehabilitation, most people are able to regain their mobility and independence after a knee replacement surgery.
