title: Spontaneous hemarthrosis 6 years after total knee arthroplasty.
abstract: Spontaneous hemarthrosis is an uncommon complication of total knee arthroplasty. We report the case of a tense hemarthrosis developing 6 years after total knee arthroplasty as a result of a prominent superolateral femoral flare eroding through an atherosclerotic superior lateral genicular artery.
