Methods Fifty patients with RA (RA group) and 73 patients without RA (NRA group) treated in the Heze Municipal Hospital from January 2014 to April 2019 were enrolled in this study. The basic information, RA information, operation and related blood loss indicators in the two groups were compared. The intraoperative blood loss, postoperative drainage and HBL were the main results. The secondary results were operation time, preoperative and postoperative hematocrit (Hct) and hemoglobin (Hb) and their variation values, cases of anemia before and after surgery, number of new anemia after surgery, autologous blood and allogeneic blood transfusion, etc. The correlation factors of HBL in RA group were analyzed by multi-linear regression model. Results Therlogeneic blood were independently correlated to HBL (β=0.363, -0.272, 0.210, 1.204, all P less then 0.05). Conclusions There is no difference in TBL, intraoperative blood loss, postoperative drainage and operation duration between the RA and NRA group, while HBL and the proportion of HBL in the TBL are higher in the RA group. The RA group has higher Steinbrocker rating, no DMRDs and more Hb changes.Objective To evaluate the effects of neuromuscular exercise therapy on joint stability of knee osteoarthritis (OA) patients. Methods One hundred and ten patients with knee OA were enrolled in this ongoing prospective cohort study at Arthritis Clinic and Research Center, Peking University People's Hospital from September 2017 to October 2018. The treatment consisted of six-week neuromuscular exercise therapy. The participants were followed up at 6 weeks and 3 months after the therapy. The stability of the joint was eva
