In total knee arthroplasty (TKA), the posterior-cruciate ligament-retaining (CR) and posterior-cruciate-ligament stabilized (PS) techniques are widely used depending on the individual preference of the surgeon. Comparative analysis of these two techniques is a major topic of investigation in arthroplasty research. The hypothesis of the present study is that compared with the CR technique, the PS technique is associated with a worse gait pattern. Smart-phone based gait analysis and patient-reported functional outcomes are evaluated in patients undergoing total knee arthroplasty with a CR and a PS technique, at 3, 6, and 12 months postoperatively.


Patients undergoing total knee arthroplasty are randomized to posterior-cruciate ligament-retaining (CR) and posterior-cruciate-ligament stabilized (PS) groups by generating random numbers with Microsoft Excel. The patients are/will be evaluated preoperatively and at 3, 6, and 12 months postoperatively, with knee scores (KSS and KOOS), life quality (SF-12), and smart-phone based gait analysis. All data will be calculated as mean and standard deviation values. The Student's t-test will be used for statistical analysis of the patient data. Statistical calculations will be performed using SPSS vn.22.0 software (IBM SPSS Statistics for Windows, Version 22.0. Armonk, NY, USA).
