Revision Total Knee Arthroplasty: Complications and Results
Revision total knee arthroplasty (RTKA) is growing exponentially due to changes in habits in the population and the increase in life expectancy. Identifying the cause of failure of the primary arthroplasty with the clinical exam and with radiological and serological tests is fundamental to achieving an acceptable result. The management of soft tissues, bone stock loss, correct alignment, and control of possible associated infection poses a challenge in the reconstruction of the joint. Comorbidities such as obesity and diabetes should be considered at the time of surgical planning as well as the possible occurrence of adverse effects. Currently, there is wide variability in designs on the orthopedic market with various degrees of constriction, as well as the possibility of metaphyseal supplements for managing difficulties (augments, cones, or sleeves). However, the rate of medical and surgical complications continues to be high, and the results are less predictable than in in the primary surgery. In this chapter, we address all these issues with the studies available in the recent and classic literature; noting the complexity of joint reconstruction, these specific surgeries should be performed at institutions that have the support of a multidisciplinary team to reduce complications and achieve better outcomes.
