Total hip arthroplasty (THA) is one of the most cost-effective and successful procedures in orthopedics. However, assessing the post-operative range of motion (ROM) remains a challenge due to the limitations of traditional measurement methods. This study aimed to evaluate hip and spine ROM post-operatively and single-leg balance, using a single-camera markerless motion capture system, and compare outcomes with pre-operative ROM and with an age-matched healthy control group.
An interventional study was conducted from January 2018 to December 2021. Twenty patients with hip osteoarthritis underwent THA and were assessed using a single-camera markerless system (Kinetisense software). Measurements were taken one month pre-operatively and one year post-operatively.
Significant improvements were observed in hip and lumbar spine ROM variables after THA. The most notable enhancements were in hip and spinal flexion. Compared to the control group, the THA group showed minor deficits in hip ROM, particularly in external rotation. Single-leg balance demonstrated improved stability post-operatively.
The single-camera markerless motion capture system offers a promising alternative for assessing hip and lumbar spine ROM, presenting potential advantages over manual goniometry and traditional 3D motion capture systems. Using this system for the evaluation of patients after THA, it seems that THA significantly enhances hip and lumbar spine ROM. Future research should focus on validating the accuracy of markerless systems.
全髋关节置换术（THA）是骨科领域最具成本效益且最为成功的手术之一。然而，由于传统测量方法的局限性，评估术后活动范围（ROM）仍然是一项挑战。本研究旨在使用单摄像头无标记运动捕捉系统评估髋关节和脊柱术后的ROM以及单腿平衡，并将结果与术前ROM以及年龄匹配的健康对照组进行比较。
于2018年1月至2021年12月进行了一项干预性研究。20例髋关节骨关节炎患者接受了THA手术，并使用单摄像头无标记系统（Kinetisense软件）进行评估。在术前1个月和术后1年进行测量。
THA术后髋关节和腰椎ROM变量有显著改善。最明显的改善是髋关节和脊柱前屈。与对照组相比，THA组在髋关节ROM方面存在轻微不足，尤其是在髋关节外旋方面。单腿平衡在术后显示出稳定性提高。
单摄像头无标记运动捕捉系统为评估髋关节和腰椎ROM提供了一种有前景的替代方法，与手动量角器和传统3D运动捕捉系统相比具有潜在优势。使用该系统评估THA术后患者，THA似乎能显著提高髋关节和腰椎ROM。未来的研究应侧重于验证无标记系统的准确性。
