【 摘 要 】

The number of surgical revisions of total knee arthroplasty (TKA) is increasing1 due to the steady increase in the number of TKA procedures.2,3 The principal reasons for TKA revision are aseptic loosening, infection, stiffness and extensor mechanism complications.4 TKA revision often requires the use of more constrained implants. In the literature, hinged implants characterize the tibiofemoral junction. They are the most constrained types of implants. They are used when the capsule and ligament constraints have failed completely5 or when massive bone defects are present.6 It is uncertain whether the evolution in bone loss reconstruction7,8 and bone fixation methods, or the introduction of rotation and high modularity have improved the outcomes for hinged knee implants.9 While there is abundant literature on the outcomes of TKA revision, only a few reports focus on the benefits of hinged implants in revision surgery, and even fewer focus on their indications. Should hinged implants be used only for lower-limb salvage surgery or should they be a regular choice for TKA revision surgery? Are their outcomes improving, or do they remain unsatisfactory?.
