Commentary on “Midterm clinical and radiographic results of mobile bearing revision total knee arthroplasty”

Revision knee replacement is a challenging procedure that will become more commonplace, as the number of failed total knee arthroplasty (TKA) cases predictably accompany the expected growth of primary TKAs. Implant choice is only one of many variables surgeons must decide on when performing revision TKA (1). The trial conducted by Raymond Kim and colleagues on Midterm Clinical and radiographic results of mobile-bearing revision TKA was very well written, with average 5-year and minimum 2-year follow up.
