- What are knee prosthetics?
Prosthetics are devices used to replace natural components of our body. The knee prostheses replace the deteriorated knee joints, maintaining their function.
These prostheses have metal and polyethylene components that mimic the normal knee.
- Who are the people who will need prostheses?
People with advanced knee osteoarthritis (wear) accompanied with significant pain, usually over 60 years.
- Will the prostheses need to be replaced after many years?
The prostheses we use today are more modern and have a longer useful life. But, like any other prostheses, they suffer constant wear and may need to be replaced after, on average, 15 to 20 years.
- How is the surgery performed?
The surgery is performed with an incision in the anterior region of the knee. Through it, we perform the replacement of the joint surface by a prosthesis. The surgery lasts approximately 90 minutes.

- Is the surgery too painful?
The surgery is painless. In the first few days after surgery, patients are given prophylactic analgesic medications, that is, they should be taken before any nuisance can be felt.
- What kind of anesthesia is used?
Spinal anesthesia. Anesthesia performed in the back region. It is the same used in cesarean sections. In specific cases, we will need to use general anesthesia for patient safety.
- Will I need to be hospitalized?
Yes. We request the stay in the Hospital last 2 to 3 days after the surgery, for medication and care.
- When can I walk normally?
The day after the surgery, the patient can already walk with the use of walkers.
3 to 6 weeks after surgery, the patient may gradually return to their routine activities without walkers or crutches. Physiotherapeutic monitoring in these first few weeks is very important for early return to usual activities and to guarantee a successful surgery.
- Is there any particular care that knee prosthesis wearers should take?
- Maintain physical activity for muscle strengthening (bodybuilding with guidance)
- Special precautions to avoid falls
- Staying at the right weight
- Regular follow-ups with your orthopedist to ensure the health of your knees.
