Synovectomy of the knee for hemophilic arthropathy
I Montane, NC McCollough and EC Lian
Synovectomy of the knee for the control of recurrent hemarthrosis was
performed in thirteen patients with hemophilic arthropathy. Preoperatively,
all patients had experienced an average of three bleeding episodes into the
affected joint per month, and had been unresponsive to at least six months
of medical management. Radiographically, all knees had either Stage-II or
Stage-III hemophilic arthropathy. The average age of the patients at the
time of synovectomy was sixteen years and the average length of follow-up
was 7.3 years (range, two to eleven years and seven months). Although the
motion of the knee remained unchanged postoperatively in two patients, ten
patients had an average loss of 41 degrees. One patient eventually required
an arthrodesis. Radiographically, there was slight further joint
deterioration after synovectomy, and no knee progressed beyond Stage-III
hemophilic arthropathy. Only one patient in our series had a recurrent
spontaneous hemarthrosis of the synovectomized knee, although two others
had traumatic bleeding episodes. The complications included three immediate
postoperative hemarthrosis requiring surgical evacuation, isoimmune
hemolytic anemia in one patient, patellofemoral adhesions in two knees, and
a total fibrous ankylosis that required a knee arthrodesis in one patient.
It was concluded from our study that chronic recurrent hemarthrosis and the
pain associated with persistent synovitis in the hemophilic knee can be
effectively eliminated for as many as twelve years after open synovectomy,
although usually with significant loss of motion of the knee. This
procedure also appeared to slow the progression of arthropathy, and no
patient had been considered for a total knee replacement at the time of
writing.
