Table 1 Studies comparing posterior cruciate retaining vs posterior cruciate sacrificing total knee replacement methods
Ref.Type of studyOutcome
Verra et al[15]Meta-analysis of randomized and quasi-randomized controlled trials, comparing retention with sacrifice of the PCL in primary TKRNo clinically relevant differences found. Range of motion was 2.4° higher in the PCL sacrificing group
Li et al[14]Meta-analysis of randomized controlled trials comparing posterior cruciate-retaining with posterior stabilized TKANo differences between the 2 designs
Yagishita et al[13]Prospective, randomized study comparing high-flexion CR design implanted in one knee and high-flexion PS design implanted in the other knee in simultaneous bilateral TKAPS prosthesis better in postoperative knee motion, posterior knee pain at passive flexion and patient satisfaction
Seon et al[12]Prospective randomized trial, comparing in vivo kinematics, range of motion, and functional outcomes in patients who received either a high-flexion cruciate retaining or a high-flexion cruciate substituting TKRNo differences in clinical outcomes. PS TKR superior to CR TKR in weight-bearing maximum flexion and posterior femoral roll-back
Kim et al[11]Prospective randomized trial, comparing ROM and functional outcome in knees receiving either a high-flexion posterior cruciate-retaining or a high-flexion posterior cruciate-substituting TKRNo differences among groups
Chaudhary et al[10]Prospective randomized study comparing range of motion of posterior CR vs posterior cruciate-substituting (PS) (TKA)No differences among groups
Harato et al[9]Prospective, randomized clinical trial comparing midterm outcomes of posterior CR vs posterior cruciate-substituting (PS) procedures using the Genesis II (TKA)No significant difference in knee function, postoperative complications and patient satisfaction. Superior ROM in the PS group
Jacobs et al[8]Systematic review and meta-analysis of prospective randomized trialsRange of motion 8° higher in the posterior-stabilized group compared to the PCL retention group
