Abstract
The purpose of the present study was to retrospectively
evaluate the therapeutic outcome of minimally
invasive synovectomy assisted with arthroscopy (MISAA).
From 1995 to 2003, MISAA was performed on 30 knees of
18 rheumatoid arthritis patients. The mean follow-up period
was 74.4 months. Radiographic assessment according
to Larsen’s radiological classification, the conversion ratio
to total knee arthroplasty (TKA), and postoperative change
of the range of flexion were evaluated retrospectively.
There were 10 knees in grade I, 14 knees in grade II, and 6
knees in grade III, preoperatively. All the knees in grade I
and 8 of 14 knees in grade II maintained the same grade
until the latest follow-up. The other 6 knees in grade II and
all the knees in grade III deteriorated to grade IV and were
converted to TKA after MISAA. The mean range of flexion
significantly increased postoperatively except the knees that
were converted to TKA. MISAA is effective for rheumatoid
knees in grade I or II, and improves range of flexion.
