Dowdle SB, et al. - This large multicenter cohort study was undertaken to elucidate the incidence, timing, and risk factors associated with manipulation under anesthesia (MUA) following revision total knee arthroplasty (rTKA). As per the findings, among those who underwent rTKA, MUA was carried out in 1.7%. Data also indicated that younger patients, as compared with patients over 50 years old, were 6 times more likely to have an MUA.
