How Long Is Surgery For Knee Replacement

How The Knee Works

How Long Will My Total Knee Replacement Last?

The knee joint acts as a hinge between the bones of the leg and is effectively 2 joints. The major joint is between the thigh bone of the upper leg and the shin bone of the lower leg . The smaller joint is between the kneecap and the upper leg .

A smooth, tough tissue called articular cartilage covers the ends of the bones, allowing them to slide smoothly over each other. The synovial membrane covering the other surfaces of the knee joint produces synovial fluid, which lubricates the joint, reducing friction.

If the articular cartilage becomes damaged or worn, the ends of the bones rub or grind together, causing pain and difficulty moving the knee joint.

Replacing the damaged knee joint with an artificial one can help reduce pain and increase mobility.

Are There Any Reasons Why I Cant Have A Knee Replacement

Unfortunately, some people may not be able to have a knee replacement even though their arthritis is very bad. This may be because:

  • your thigh muscles are very weak and may not be able to support your new knee joint
  • there are deep or long-lasting open sores in the skin below your knee, increasing your risk of infection.

Time Off Work After Knee Arthroscopy

The time youll need to take off work will depend on the type of job you have. For instance, if you work in an office, its likely youll be able to return after a week or two. However, if your work requires a commute, youll still need to factor this in. Air travel should be avoided for around a week after surgery. Dont hesitate to ask your doctor or surgeon for more information about returning to work.

Can You Replace Both Knees At The Same Time

The short answer is: yes. Total knee replacement surgery for both knees can be performed. However, this treatment option comes with factors to consider. For instance, to qualify for the surgery, youll need to be healthy and at the younger end of the typical age range for knee surgery.

You will also need to think about the recovery process. With both knees operated on, the initial recovery period will become much more of a challenge. A bilateral procedure leaves you without a good leg to support you. On the other hand, single knee replacement patients would typically be walking with minimal aid within a few days.

On the other hand, having both knees operated on at the same time means you would only have one recovery period to negotiate. This option is better for patients who might struggle to take a lot of time off work.

What Is The Best Age To Have A Knee Replacement

Although available to most age groups, knee replacement surgery doesnt tend to be recommended to younger patients below the age of 50.

A Look At The Knee Joint

Knee Replacement – Everything you need to know

The knee functions as a hinge joint, which means bones move in one direction back and forth with limited motion in other directions . Hinge joints are complex and contain many different muscles and tissues the fingers, toes, elbows, and ankles are also hinge joints.

Your knee is made up of three main bones: the femur, the tibia, and the patella . In a healthy knee, cartilage coats the bones in the knee joint to help it move smoothly and provide a shock-absorbent cushion. In an arthritic knee, the cartilage surface starts to break down resulting in bone-on-bone contact that causes pain, stiffness, and swelling. Several conditions can cause knee pain, but arthritis and overuse injuries are the most common causes of chronic knee pain.

J Infect Med 11: 2114, April 2022 Multiple univariate and multivariate models were used in logistic regression analysis of the data. A median hospital stay of 3 days was observed in the study.
