摘要Introduction: Cruciate retaining total knee arthroplasty (CR-TKA) offers advantages over posterior stabilised total knee arthroplasty, but achieving optimal soft tissue balance can be challenging due to the presence of the posterior cruciate ligament (PCL). This study aimed to compare the clinical outcomes of CR-TKA using manual instrumentation, MAKO and Verasense.
Methods: 200 patients received CR-TKA in AHNH between 2019-2022 were included. They were divided into: conventional (49 cases), MAKO (99 cases), and Verasense (52 cases). Pre-operative and post-operative measurements of knee range of motion (ROM), Knee Society Score (KSS) Function Score, Oxford Knee Score (OKS), and KSS Knee Score were compared using SPSS 22.
Results: There were no significant differences in patients’ demographics among 3 groups. Verasense group showed a significantly better reduction in pain scores (7.7, 6.9, 7.1 p=0.03) and improvement in KSS Knee Score (125%, 98%, 83% p=0.01) compared to MAKO and conventional groups. However, there were no significant differences in knee ROM, KSS Function Score, and OKS post-operatively among 3 groups.
Discussion and Conclusion: The findings suggest that Verasense, with its real-time pressure readings in both compartments of the knee joint during surgery, can contribute to improved pain scores and KSS Knee Score. On the other hand, MAKO still relies on subjective tests and does not provide actual pressure readings. Enhancing the MAKO system with a pressure sensor could potentially further improve soft tissue balance and patient outcomes. Further research with larger sample sizes and longer follow-up periods is warranted to validate these findings and explore its possible benefits.
