Overall satisfaction of patients with total knee replacements
In 90% of cases, the outcome of the knee replacements is regarded as excellent. This success rate even exceeds that of hip replacements, which are considered a benchmark.
The first factor observed concerns the disappearance of the pain, which, let us not forget, is the main reason for choosing a total knee replacement. In 60% of cases, the pain totally disappears. It reappears episodically in 30% of cases, but is moderate enough not to require any treatment. In 10% of cases, medical treatment may be required to provide the patient with occasional relief.
The second criterion, knee mobility, is largely recovered enabling once again normal use of the knee: walking without crutches, going up and down stairs… Patients having undergone the operation even resume physical activities, being careful to choose them accordingly.
Lifespan of the implants
We now have over 25 years of experience in total knee implants, and there is no denying they can last all that time! According to statistical research, 80 to 90% of implants are still in place after 15 to 20 years. However, it is clear that the risk of loosening and wear increases with time.
L’âge du patient reste par conséquent un élément important à prendre en compte. Un patient jeune et actif risquera, en effet, davantage de voir sa prothèse s’user ou se desceller qu’un sujet plus âgé. Pour autant, les conditions opératoires de la prothèse totale de genou sont telles qu’un éventuel changement peut aujourd’hui se faire dans de très bonnes conditions.
