Revision TKA with a condylar constrained prosthesis using metaphyseal and surface cementation: A minimum 6-year follow-up analysis

The increasing number of revision knee arthroplasty result in the more frequently use of a constraint implant but results from previous reports are difficult to interpret. The purpose of this study was to compare the long-term outcomes of superficial cemented versus metaphyseal cemented in revision total knee arthroplasty with a condylar constrained arthroplasty.
