To assess the validity and informational value of the material about the posterior cruciate ligament (PCL) provided on TikTok.
The terms "posterior cruciate ligament" and "PCL" were used as keywords for an extensive search of the video content on the TikTok video platform. The video duration and the numbers of likes, shares, saves, and views were recorded for each video. The quality and reliability assessments of the video content were conducted via the DISCERN instrument, benchmark criteria, and Global Quality Score.
A total of 48 videos were included in the analysis, of which 18 (37.5%) were posted by physiotherapists; 14 (29.2%), by private users; and 16 (33.3%), by medical doctors/doctors of osteopathic medicine. Most of the information concerned clinical examination (12-25%) or patient experience (12-25%). Video content was focused on education in 26 videos (54.2%), patient experience in 11 (22.9%), and rehabilitation in 11 (22.9%). Most of the videos used music as the background audio (29-60.4%). The mean length of the videos was 29.29 ± 26.95 seconds. The mean number of views was 565,863.02 ± 2,686,462.45, whereas the mean numbers of likes, comments, shares, and saves were 15,533.58 ± 73,143.51, 127.85 ± 671.49, 661.38 ± 3,049.96, and 1,473.90 ± 7,523.37, respectively. The mean DISCERN score, score, and Global Quality Score were 16.15 ± 2.53, 0.15 ± 0.36, and 1.08 ± 0.28, respectively, indicating the poorest quality for all 3 indices.
Videos about the PCL on the TikTok platform are not comprehensive and have low educational value.
Given the growing number of patients using social media to seek information about their medical concerns, it is crucial for orthopaedic health care practitioners to recognize the constraints of TikTok videos that focus on the PCL as possible sources of information for their patients.
评估TikTok上提供的关于后交叉韧带（PCL）的材料的有效性和信息价值。
使用术语“后交叉韧带”和“PCL”作为关键词，在TikTok视频平台上广泛搜索视频内容。记录每个视频的时长以及点赞、分享、保存和观看次数。通过DISCERN工具、基准标准和全球质量评分对视频内容进行质量和可靠性评估。
分析共纳入48个视频，其中18个（37.5%）由物理治疗师发布；14个（29.2%）由普通用户发布；16个（33.3%）由医生/整骨医学医生发布。大多数信息涉及临床检查（12 - 25%）或患者体验（12 - 25%）。26个视频（54.2%）的内容侧重于教育，11个（22.9%）侧重于患者体验，11个（22.9%）侧重于康复。大多数视频使用音乐作为背景音频（29 - 60.4%）。视频的平均时长为29.29±26.95秒。平均观看次数为565,863.02±2,686,462.45，而平均点赞、评论、分享和保存次数分别为15,533.58±73,143.51、127.85±671.49、661.38±3,049.96和1,473.90±7,523.37。平均DISCERN评分、[此处原文可能有误，推测为某个评分，暂译为“[该评分]”]评分和全球质量评分分别为16.15±2.53、0.15±0.36和1.08±0.28，表明这三个指标的质量都很差。
TikTok平台上关于PCL的视频不全面且教育价值低。
鉴于越来越多的患者使用社交媒体来寻求有关其医疗问题的信息，骨科医疗从业者认识到TikTok上侧重于PCL的视频作为患者信息来源的局限性至关重要。
