Abstract: Objective To compare the differences of early clinical efficacy between posterior cruciate-substituting(PS) prosthesis and posterior cruciate-retaining(CR) prosthesis for the patients who underwent total knee arthroplasty(TKA). Methods From August 2015 to July 2018, 67 patients who underwent TKA were retrospectively evaluated. There were 32 PS prosthesis and 35 CR prosthesis. The operation time, postoperative drainage blood volume, hospital stay, range of knee joint motion, and Hospital for Special Surgery knee score (HSS) were recorded. Results The operation time in PS and CR groups was (91.77±6.53) min and (87.48±5.83) min, respectively, with statistical significant differences between the two groups (P<0.05). The postoperative drainage blood volume in PS and CR groups was (315.81±18.34) mL and (203.67±14.59) mL, respectively, with statistical significant difference (P<0.05). There were no differences between the two groups of the hospital stay, range of knee joint motion and HSS (P>0.05). Conclusion The early clinical efficacy of both PS and CR prosthesis after TKA was satisfactory. The choice of TKA prosthesis type should be based on patient conditions and surgeon's experiences.
