Abstract EN
The rotating hinge knee prosthesis is a popular intervention in patients lacking stability with highly constrained total knee arthroplasty.
Despite improvements in design, nonmechanical and mechanical complications continue to be a problem.
Dislocation of the hinge has been widely described, mainly due to the component fracture.
Few reports describe isolated dislocation of the rotating stem.
We report a case of isolated disengagement of the rotating hinge mechanism, due to severe flexion gap imbalance, leading to subsequent posterior dislocation of the hinge and anterior knee dislocation, in a patient with a history of multiple total knee arthroplasty revisions.
This case suggests the importance of the soft tissue balancing, the adequate patellar tracking, and use of a long cylindrical, minimally tapered rotating stem in hinge arthroplasty to minimize hinge dislocation.
