To test 1) if the 45-second Anterior Knee Pain Provocation Test (AKPP-test) could differentiate between adolescents with patellofemoral pain (PFP) and pain-free controls and; 2) whether improvements in the AKPP-test over 12 weeks were associated with improvements in self-reported knee function and pain.
Prospective cohort.
151 with PFP and 50 pain-free controls (age 10-14 years).
The AKPP-test was performed at baseline, 4- and 12-week follow-up. Pain and function were collected using Knee Injury and Osteoarthritis Outcome Score (KOOS).
At baseline, the AKPP-test provoked pain to a median of 5 points (IQR: 3-7) on the 0-10 Numeric Pain Rating Scale in adolescents with PFP, compared to 0 (IQR 0-0) in controls. Higher pain during the AKPP-test was associated with worse KOOS-Sport/Rec (r = -0.33, P < 0.001), worse KOOS-Pain (r = -0.47, P < 0.001), and pain intensity (worst pain last 24 hours) (r = -0.39, P < 0.001) at baseline. Improvements in the AKPP-test over 12 weeks were associated with improvements in KOOS Pain (r = 0.48, P < 0.001) and KOOS Sport/Rec (r = 0.40, P < 0.001).
Improvements in the AKPP-test were associated with improvements in self-report knee pain and limitations in sports, suggesting the AKPP-test may be a clinically responsive test of knee pain and sporting function in adolescents with PFP.
1）测试45秒前膝疼痛激发试验（AKPP试验）能否区分患有髌股疼痛（PFP）的青少年和无疼痛对照组；2）AKPP试验在12周内的改善是否与自我报告的膝关节功能和疼痛改善相关。
前瞻性队列研究。
151例PFP患者和50例无疼痛对照组（年龄10 - 14岁）。
在基线、4周和12周随访时进行AKPP试验。使用膝关节损伤和骨关节炎疗效评分（KOOS）收集疼痛和功能数据。
在基线时，PFP青少年在0 - 10数字疼痛评分量表上，AKPP试验引发的疼痛中位数为5分（四分位间距：3 - 7），而对照组为0分（四分位间距0 - 0）。AKPP试验期间较高的疼痛与基线时较差的KOOS - 运动/娱乐评分（r = -0.33，P < 0.001）、较差的KOOS - 疼痛评分（r = -0.47，P < 0.001）以及疼痛强度（过去24小时最严重疼痛）（r = -0.39，P < 0.001）相关。AKPP试验在12周内的改善与KOOS疼痛评分（r = 0.48，P < 0.001）和KOOS运动/娱乐评分（r = 0.40，P < 0.001）的改善相关。
AKPP试验的改善与自我报告的膝关节疼痛改善以及运动受限相关，表明AKPP试验可能是PFP青少年膝关节疼痛和运动功能的临床反应性测试。
