Recovery Trajectories After Total Knee Arthroplasty
Sponsor: Ondokuz Mayıs University
Summary
This prospective cohort study aimed to compare recovery trajectories following cruciate-retaining (CR) and posterior-stabilized (PS) total knee arthroplasty (TKA) using rehabilitation-centered patient-reported outcome measures (PROMs). Forty patients undergoing primary unilateral TKA were evaluated preoperatively and at 3 and 6 months postoperatively. Outcomes included pain intensity, functional status, kinesiophobia, health-related quality of life, and joint awareness assessed using validated PROMs including the Visual Analog Scale (VAS), WOMAC, Tampa Scale for Kinesiophobia (TSK), SF-36, and Forgotten Joint Score-12 (FJS-12). The study investigated whether posterior cruciate ligament management influences early postoperative recovery trajectories after TKA.

Interventions
Cruciate-Retaining Total Knee Arthroplasty
Primary unilateral total knee arthroplasty performed using a cruciate-retaining implant design in which the posterior cruciate ligament (PCL) was preserved. Implant selection was based on intraoperative assessment of ligament integrity and soft-tissue balance. Standardized perioperative management and postoperative rehabilitation protocols were applied to all participants.
Posterior-Stabilized Total Knee Arthroplasty
Primary unilateral total knee arthroplasty performed using a posterior-stabilized implant design incorporating a post-cam mechanism to substitute posterior cruciate ligament (PCL) function. Implant selection was determined intraoperatively according to ligament condition and soft-tissue balancing requirements. All participants received standardized perioperative care and postoperative rehabilitation.
