Dynamic change of hematological inflammation (CRP, ESR) and coagulation markers (D-dimer, Fibrinogen) of the two groups in this study. The elevation of CRP in RA-TKA was eliminated by 48.4% at 72hrs P.O. compared to CM-TKA, and its recovery into normal range can be found as early as 1st-month after RA-TKA (a); The increasement of ESR in RA-TKA was eliminated by 31.1% at 72hrs P.O., 54.5% at 1st-month P.O., 17.4% at 3rd month P.O., as compared to CM-TKA (b); The elevated D-dimer in RA-TKA was eliminated by 47.3% at 72hrs P.O., 46.0% at 1st-month P.O., compared to CM-TKA (c); There was no significant difference in content change of fibrinogen between CM-TKA and RA-TKA after TKA (d). ^*, P < 0.001, ^#, P < 0.05.
