Articular cartilage repair (ACR) procedures aim to alleviate pain and restore function for individuals with chondral defects. Rehabilitation is lengthy, and there are limited data on return to sports and exercise activities after ACR in non-elite-athlete populations. The Internet is a growing source of health-related information for patients, and it has resulted in the emergence of online health communities.
To establish a postoperative activity profile of users of an online health community who have undergone ACR of the knee and to compare this profile with those from the same community who have undergone initial anterior cruciate ligament reconstruction (ACLR).
Cross-sectional.
Tegner Activity Scale ratings were collected via a self-reported online questionnaire from 201 participants of an online health community who had undergone tibiofemoral and/or patellofemoral ACR (n = 75) or ACLR (n = 126).
A higher Tegner activity level was significantly correlated to time from surgery for ACR (P < 0.005) and ACLR (P < 0.01). At a minimum of 24 months' follow-up, the ACR group had a median postoperative Tegner score of 3, compared with 6 for the ACLR group. Tegner score was significantly negatively correlated with age at time of surgery for ACLR (P < 0.05) but not for ACR. Men demonstrated significantly higher Tegner activity levels than did women for both ACLR and ACR (P < 0.05).
Activity levels after ACR in this population increased with postoperative time but remained lower than expected when compared with current published clinical and normative data.
Engagement with an online health community may influence expectations regarding return to sports and exercise activities. Reporting of activity-level data within clinical studies should be differentiated on the basis of sex. Further research is needed to elucidate factors that determine return to sports and exercise activities after ACR.
关节软骨修复（ACR）程序旨在减轻软骨缺损患者的疼痛并恢复其功能。康复时间较长，在非精英运动员人群中，关于 ACR 后重返运动和锻炼活动的数据有限。互联网是患者获取健康相关信息的一个日益增长的来源，这导致了在线健康社区的出现。
确定在线健康社区中接受膝关节 ACR 的用户的术后活动概况，并将其与接受初始前交叉韧带重建（ACLR）的用户进行比较。
横断面研究。
通过在线健康社区的自我报告在线问卷收集 Tegner 活动量表评分，该社区的 201 名参与者接受了胫骨股骨和/或髌股 ACR（n = 75）或 ACLR（n = 126）。
Tegner 活动水平较高与 ACR（P < 0.005）和 ACLR（P < 0.01）的手术时间显著相关。在至少 24 个月的随访中，ACR 组的术后 Tegner 评分中位数为 3，而 ACLR 组为 6。Tegner 评分与 ACLR 手术时的年龄呈显著负相关（P < 0.05），但与 ACR 无关。男性的 Tegner 活动水平明显高于女性，无论是 ACLR 还是 ACR（P < 0.05）。
在该人群中，ACR 后的活动水平随术后时间增加而增加，但与当前发表的临床和规范数据相比仍然较低。
参与在线健康社区可能会影响对重返运动和锻炼活动的期望。在临床研究中报告活动水平数据时，应根据性别进行区分。需要进一步研究阐明确定 ACR 后重返运动和锻炼活动的因素。
