In the initial stage of the pain, walking support may be used. If these walking support are also unable to help walk, then knee surgery may be undertaken.

Approximately 90% people have benefited from total knee replacement. Drastic reduction in the pain has been observed. People were able to continue with their daily life activities such as walking, climbing etc. However, one cannot do rigorous activity after knee replacement.
With normal activities, the implant gradually begins its wear and tear. But working excessively may result in much quicker wear and tear of the implants. Eventually it may lead to loosening of the implant, which may be very painful.
- Infections: The area around the prosthesis or implant is a very favorable ground for bacteria to grow, thereby causing infections. Infections may happen post-surgery or after some amount of time. Minor infections are treated with anti-biotic. Major infections require revision surgery, which involves removing of the implant and treating it with antibiotics before re-inserting. If left untreated, the infections can spread in the entire body, which can prove fatal.
- Blood clots: The most common complication in the knee replacement surgery is blood clots. The clots may prove very dangerous if they travel to the lungs. Blood thinning medicines and frequent diagnosis is advised by the doctors.
- Problems of the implants: though the implants are supposed to aid in relieving the pain, in due course of time with regular activity the implants tend to wear out. The general deterioration of the implant leads to loosening of the implants. This causes painful knees again.
Precautions have to be taken both at the hospital and while at home.
- The wound has to be taken care of to avoid any infections.
- A balanced diet, rich in iron content should be consumed to help the wound heal and regain the lost energy.
- Exercise is crucial to the recovery. Gradual walk to improve mobility should be undertaken. Slowly usual routine activities should be undertaken. Exercises recommended by physiotherapists should be done several times of the day.
- Avoid falling or tripping over.
