Are there any other options?
If your arthritis is diagnosed early and only involves one part of your knee (unicompartmental), you may be a candidate for a partial knee replacement. This reduces surgery time and lowers your risks of surgery.
What age should I consider a knee replacement?
On average, the implants (parts) that are used for a knee replacement only last 10-15 years. These parts will then need to be replaced. As a result, it is recommended to utilize all forms of conservative therapy (bracing, NSAIDs, physical therapy, steroid injections) prior to a knee replacement and to delay the replacement until a later age (preferably 60-65 years and older).
Is it safe? What are the major risks?
Knee replacements are relatively safe. With any type of surgery, however, there are risks involved. Risks of total knee replacement include blood clots in the legs that can travel to the lungs called a pulmonary embolism (you will likely be placed on a blood thinner to prevent this), infection (you will be given antibiotics prior to surgery), and stiffness (you will work with physical therapy to regain function and strength after surgery).
How long will I be in the hospital after surgery?
Most patients start walking the day of surgery or the day after. Physical therapy will work with you to get you moving. The faster you get up and get moving, the faster you can get out of the hospital, usually 2-3 days after surgery.
What should I expect in terms of pain?
The pain that you have from your arthritis should subside immediately after surgery. However, you may have discomfort relating to the surgery itself. This should get better with time and can be controlled with medications.
What will I be able to do and not be able to do after surgery?
High impact activities such as running and skiing should be avoided immediately after surgery. Depending on which knee was replaced, you will not be allowed to drive for 3-6 weeks. You are encouraged to participate in low impact activities such as walking, dancing, golfing, and gardening.
When can I return to work?
Most people take off 3-4 weeks from work to allow for healing and recovery. If you job is a sedentary one, some individuals can return to work sooner. More demanding jobs may require more time away from work.
