Recurrent hemarthrosis after total knee arthroplasty.
Seven patients developed recurrent hemarthroses following total knee arthroplasty. The average interval between arthroplasty and the first bleed was more than 20 months (range, 1-30 months). All seven required open synovectomy an average of 21 months (6-31 months) after arthroplasty. Follow-up evaluation averaged 44 months (19-60 months) and all had an excellent result without further bleeds. A prolific synovitis was seen in all cases, with histologic features revealing a chronic synovitis with fibrosis and hemosiderin staining. Entrapment of the proliferative synovial tissue between the components is postulated to be the etiology for these recurrent bleeds which averaged four per patient prior to synovectomy.
