Knee-specific patient reported outcome measures (PROMs) are important tools in evaluating the effectiveness of sports medicine interventions. The PROMs were originally developed for paper administration, but electronic data capture technologies offer potential benefits such as increased efficiency and accuracy. The aim of this study was to assess the validity of touch screen versus paper administration using several common knee-specific and general health surveys.
Agreement between scores was compared for knee-specific PROMs administered on paper versus computer; paper versus tablet; computer versus tablet in 60 patients per group undergoing ACL reconstruction. Surveys were given at pre-operative assessment and between 1 and 7 days later. Weighted kappa statistic (κ) and intraclass correlation coefficients (ICC) were calculated to test agreement between the two modalities in: IKDC Subjective Knee Form, Marx Activity Scale, Tegner Activity Level Scale, and Lysholm Knee Scale. SF-12 Physical and Mental Component Summary scores were also assessed.
Response rate was over 90 %. Mean age was 29.6 ± 10.9 years, with patients in the paper-computer cohort being 4 years older than in the other groups. Agreement was substantial or better for all PROMs collected: IKDC Subjective (ICC: 0.79); Marx (ICC: 0.70); Lysholm (ICC: 0.65); and Tegner (κ = 0.67). Agreement for the SF-12 PCS (ICC: 0.77) and MCS (ICC: 0.73) was also found to have substantial agreement.
In conclusion, touch screen-based PROMs are a valid capture method, providing reliable results relative to traditional paper survey administration. Digital methods of direct data capture may also foster multi-centre collaborations and allow for more accurate comparisons of outcomes between patient groups in clinical practice and orthopaedic research.

膝关节特定的患者报告结局测量（PROMs）是评估运动医学干预措施有效性的重要工具。这些 PROMs 最初是为纸质管理而开发的，但电子数据采集技术提供了提高效率和准确性等潜在优势。本研究的目的是评估使用几种常见的膝关节特异性和一般健康调查，通过触摸屏与纸质管理来评估有效性。
在接受 ACL 重建的每组 60 名患者中，比较膝关节特异性 PROMs 纸质与计算机管理、纸质与平板电脑管理、计算机与平板电脑管理之间的评分一致性。在术前评估和术后 1 至 7 天之间进行了调查。使用加权 Kappa 统计量（κ）和组内相关系数（ICC）来测试两种方式之间的一致性：IKDC 主观膝关节评分表、Marx 活动量表、Tegner 活动水平量表和 Lysholm 膝关节量表。还评估了 SF-12 身体和精神成分综合评分。
应答率超过 90%。平均年龄为 29.6±10.9 岁，纸质-计算机组的患者比其他组年长 4 岁。所有收集的 PROM 均具有高度或更好的一致性：IKDC 主观（ICC：0.79）；Marx（ICC：0.70）；Lysholm（ICC：0.65）；Tegner（κ=0.67）。SF-12 PCS（ICC：0.77）和 MCS（ICC：0.73）的一致性也被认为具有高度一致性。
总之，基于触摸屏的 PROM 是一种有效的采集方法，与传统的纸质调查管理相比，提供了可靠的结果。数字直接数据采集方法还可以促进多中心合作，并允许在临床实践和矫形研究中更准确地比较患者群体之间的结果。
