Abstract：Objective To compare the differences of early clinical effects between mobile-bearing/posterior cruciate retaining (MB/CR) prosthesis and fixed bearing/posterior cruciate stabilizing (FB/PS) prosthesis for the patients who underwent total knee arthroplasty (TKA).Methods Total of 56 TKA patients treated from October 2008 to August 2013 in Tongzhou Xinhua Hospital were randomly divided into two groups,in which A group using MB/CR prosthesis (n = 30),and B group using FB/PS prosthesis (n = 26).The postoperative drainage blood volume was recorded,and the levels of hemoglobin of TKA patients in two groups at preoperation and 3 days after surgery were examined,also,the improvement of knee joint function 2 weeks after surgery was evaluated by American Knee Society score (KSS).Results Postoperative drainage blood volume in A group and B group was (450 ± 158),(605 ± 132) mL respectively,the difference between two groups had statistical significance (P <0.05).Postoperative hemoglobin levels in two groups were lower than the preoperative ones,while the postoperative KSS were all improved (P <0.05).In A group,hemoglobin levels 3 days after the operation were higher than those in B group,but the range of motion (ROM) of knee joint 2 weeks after surgery was lower than that in B group,the differences between two groups showed statistical significance (P <0.05).As for KSS clinical and functional scores 2 weeks postoperatively,there were no statistical differences between 2 groups (P >0.05).Conclusions Both types of MB/CR and FB/PS prosthesis could obtain satisfactory early effects after TKA.Perioperative estimate blood loss and postoperative hemoglobin levels in TKA with MB/CR prosthesis are better than FB/PS prosthesis,while patients who underwent FB/PS prosthesis could achieve better ROM of knee joint.As a result,the choice of TKA prosthesis type should be based on patient conditions and preference,as well as surgeon's recognition and proficiency.
