[NOVEL CONCEPTS AND CHANGES IN TOTAL JOINT ARTHROPLASTY IN THE 21ST CENTURY].

Total joint arthroplasty (TJA) is amongst the most common elective orthopedic surgeries. Since their introduction in 1951 there have been changes not only in prosthesis design and surgical approaches, but also in patient management, anesthesia, drug regimen and robotic arm assistance. These changes led to advancement in patient safety and shorter hospitalization. Today TJA is accessible for a wider age and function range of patients, which has led to an exponential growth in the number of procedures conducted.
