SYNOVIAL FLUID ANALYSIS AS A DIAGNOSTIC AID IN ARTHRITIS.
Yun Ku Choi
Dept. of Medical Science, Yonsei University
Extensive knowledge of the characteristics of synovial fluid has been available
for at least the past 30 years, when a Monograph on the subject by Kling first
appeared in 1938.
Since that time, Ropes, Bauer(1953) and Hollander(1960, 1961, 1965) have
published classic.
Monographs on their extensive studies and findings of synovial fluid.
Specific laboratory tests for diagnosis of various forms of arthritis are usually
lacking. For example, the test for the rheumatoid factor in serum may be helpful in
establishing the diagnosis of rheumatoid arthritis, but these are often negative in
early cases and L.E. phenomenon is often negative in the early stage or between
severe exacerbations of the systemic lupus erythematosus.
It has become increasingly clear during the past 10 years that synovial fluid
analysis is both the most valuable and yet the most neglected differential
diagnostic test for arthritis.
Studies of synovial fluid have presented a virtually unexplored frontier in the
investigation of arthritis.
So, we studied the synovial fluid from 100 cases of various forms of arthritis in
the Department of Orthopedic Surgery, Severance Hospital from May, 1968 to May,
1969.
100 cases of arthritis are ; 30 cases of Osteoarthritis, 20 cases of Traumatic
arthritis, 25 cases of Rheumatoid arthritis, 10 cases of Septic arthritis, 5 cases
of Tuberculous arthritis, and 10 cases of Non-specific bursitis.
The synovial fluid were aspirated from the involved joints in aseptic conditions
and following studies were done.
1) General appearance.
2) Mucin content by Acetic acid PPT. or Ropes test.
3) Viscosity by Drop test.
4) Cell count by Wright's stain.
WBC : Total and differential count.
RBC count.
5) synovial sugar by Folin Wu method.
6) Fasting blood sugar by Folin Wu method.
7) Sugar difference between synovial sugar and Fasting blood sugar.
8) Total protein by Kingsley's Biuret method.
9) Bacterial culture in Septic arthritis.
10) Microscopic examination.
" RA cells" by Sternheimer - Malbin stain in Rheumatoid arthritis.
Cartilage fragments with simple wet preparations in Osteoarthritis.
6 kinds of arthritides were grouped into 3 categories based on the degree of
inflammatin of the synovial menbrane as reflected by synovial fluid changes
according to Ropes and Bauer's classification (1953).
The first group, consisting of Osteroarthritis and Traumatic arthritis, was
associated with mild inflammatory reactions and increased amount of fluid, but no
significant changes in the number of WBC, sugar concentration, or quality of mucin.
The second group was characterized by more severe inflammation of the synovial
membrane and included Rheumatoid arthritis, Septic arthritis and Tuberculous
arthritis.
The second group was associate with decreased mucin content, increased WBC,
polymorphonuclear leucocytes, RBC and protein and decreased amount of synovial
sugar.
"RA cells" were found in all cases of Rheumatoid arthritis and cartilage
fragments in Osteoarthritis under the light microscope.
The third group, an intermediate group - Non specific bursitis - might have some
distinguishing characteristics of synovial fluid but these were not usually
diagnostic.
