Total knee arthroplasty (TKA) is intended to provide increased patient mobility and reduced pain by replacing the damaged knee joint cartilage. Traditionally, TKA was reserved for elderly patients with end-stage knee pain from arthritis. Total knee replacement may be considered for younger patients if, in the opinion of the patient and the surgeon, potential benefits of the procedure unequivocally outweigh the risks associated with failure of implants.
To achieve long-term success after TKA, an honest discussion regarding expectations versus activity profile after knee replacement needs to be held between the patient and the surgeon. This includes severely crippled patients with multiple joint involvement, for whom a gain in knee mobility may lead to an expectation of significant improvement in pain levels and the quality of their lives.
