Knee prosthesis is the material made from known biocompatibility with the body and transplanted in the individual’s knee following diseases called arthrosis to replace the knee joint.
Knee prosthesis is used with two reasons: pain and restriction in daily living activities. While pain is an important factor, the extent of impairment of the knee and whether or not solutions capable of preserving the joint are possible. If treatments that will preserve the joint ae possible, these treatments must be administered in the first place. If the joint is deformed in time loses movement, the patient will have difficulties in his/her daily living activities. If the joint has impaired so as repair will not be possible, and his/her age and health status allow it, prosthesis operation will be recommended. The average lifetime of a knee prosthesis within the human body is 15 to 20 years. Therefore, knee prosthesis is recommended for patients between 50 and 80 years of age. The individual will have to continue his/her life with an artificial knee joint. In order to ensure that the knee prosthesis will have a long lifetime, the following are required:
- The patient must avoid risky activities such as jumping or falling from heights,
- Activities that will shorten the lifetime of the prosthesis must be avoided,
- The patient must be under regular control following the operation.
