What Is Total Knee Replacement
A total knee replacement is a surgical procedure in which one's knee joint is removed and replaced with an artificial joint. Depending on your particular needs, the artificial joint, called a prosthesis, will be made of various materials including metal and plastic.
During knee replacement surgery, your surgeon will make an incision (cut) on the front of your knee. The end of your femur (thigh bone) is trimmed and resurfaced with a metal cover or shell. The end of the tibia (lower leg bone) is trimmed and resurfaced with a plastic and metal implant.
The surgery takes about two hours, but a successful knee replace-ment begins long before you enter the hospital.

Your Team at CPMC
Our nurses will be with you from the moment you arrive through surgery and until you are discharged. They work with your surgeon to make sure you are safe and on the right track toward recovery, while making sure your pain is under good control.
R.N. Case Manager
Your nurse case manager helps you make arrangements for going home, such as:
- Home therapy
- Discharge prescriptions
- Medical equipment
- Extra help at home
A physical therapist will visit you one or two times a day to teach you how to safely:
- Get in and out of bed
- Transfer in and out of a chair
- Walk with the appropriate assistive device (front-wheeled walker or crutches) on flat surfaces, stairs and curbs
- Get in and out of car safely
An occupational therapist will see you once a day during your hospital stay to teach you how to safely perform your activities of daily living:
- To sit down on/get up from the toilet
- Get in and out of a bathtub or shower stall
- Use adaptive equipment during hygiene care, dressing and bathing
- Simple activities at the sink or kitchen counter
Visiting Nursing and/or Physical/Occupational Therapy
You may need nursing and/or physical/occupational therapy on a short-term basis at home. The focus of home health care is to help you adjust to the physical changes following surgery. They will help you find out which services are covered under your insurance plan.

Managing Your Pain
Although there may be some discomfort after your surgery, keeping your pain under control speeds your recovery. Less pain will make it easier to concentrate on getting around safely on your new knee. When you are comfortable, you are better able to walk, breathe deeply and cough.
You can help your doctors and nurses "rate" your pain using the pain scale. 0 means no pain and a 10 on the scale means the worst pain you can imagine.
- Do not wait until the pain is severe (very bad).
- Tell your nurses and doctors if you have pain.
- If your pain suddenly gets worse or you experience chest pain or have trouble breathing, tell your nurses immediately.
We Manage Pain In Many Ways
We use several ways to help control your pain so you can focus on your physical and occupational therapy exercises
- We may give you medications before surgery to help minimize the pain you would otherwise experience after surgery.
- We use different types of pain medications (“multimodal analgesia”) that work well together to control pain.
- Since pain medication can make some people feel nauseated, we also give you medications to prevent and control nausea.
- Ice and repositioning are also effective ways to control pain.
