To engage clinicians in diagnosing patellar tendinopathy in large surveillance studies is often impracticable. The Oslo Sports Trauma Research Centre-patellar tendinopathy (OSTRC-P) questionnaire, a self-report measure adapted from the OSTRC questionnaire, may provide a viable alternative.
To evaluate the diagnostic accuracy of the OSTRC-P questionnaire in detecting patellar tendinopathy in youth basketball players when compared to clinical evaluation.
Following the STAndards for Reporting of Diagnostic accuracy studies guidelines, the researchers recruited 208 youth basketball players (13-18 years of age) for this prospective diagnostic accuracy validation study. Participants completed the OSTRC-P questionnaire (index test) prior to a clinical evaluation (reference standard) by a physical therapist blinded to OSTRC-P questionnaire results. Sensitivity, specificity, predictive value, likelihood ratio, and posttest probability were calculated. Linear regression was used to examine the association between the OSTRC-P questionnaire severity score and the patellar tendinopathy severity rating during a single-leg decline squat.
The final analysis included 169 players. The OSTRC-P questionnaire had a sensitivity of 79% (95% confidence interval [CI]: 65%, 90%), specificity of 98% (95% CI: 94%, 100%), positive predictive value of 95% (95% CI: 83%, 99%), negative predictive value of 92% (95% CI: 86%, 96%), positive likelihood ratio of 48 (95% CI: 12, 191), and negative likelihood ratio of 0.21 (95% CI: 0.12, 0.37). The posttest probabilities were 95% and 8%, given positive and negative results, respectively. A positive association was found between OSTRC-P questionnaire severity score and single-leg decline squat rating (β = 0.08; 95% CI: 0.03, 0.12; P = .001).
The OSTRC-P questionnaire is an acceptable alternative to clinical evaluation for self-reporting patellar tendinopathy and grading its severity in settings involving youth basketball players.

在大规模监测研究中让临床医生参与诊断髌腱病往往是不切实际的。奥斯陆运动创伤研究中心-髌腱病（OSTRC-P）问卷是 OSTRC 问卷的一个自我报告测量版本，它可能是一个可行的替代方案。
当与临床评估相比时，评估 OSTRC-P 问卷在检测青少年篮球运动员髌腱病方面的诊断准确性。
根据诊断准确性研究的 STAndards for Reporting 指南，研究人员招募了 208 名青少年篮球运动员（13-18 岁）进行这项前瞻性诊断准确性验证研究。参与者在物理治疗师进行临床评估（参考标准）之前完成 OSTRC-P 问卷（指数测试），该治疗师对 OSTRC-P 问卷的结果不知情。计算了敏感性、特异性、预测值、似然比和后验概率。线性回归用于检查 OSTRC-P 问卷严重程度评分与单腿下降蹲时髌腱病严重程度评分之间的关联。
最终分析包括 169 名参与者。OSTRC-P 问卷的敏感性为 79%（95%置信区间[CI]：65%，90%），特异性为 98%（95%CI：94%，100%），阳性预测值为 95%（95%CI：83%，99%），阴性预测值为 92%（95%CI：86%，96%），阳性似然比为 48（95%CI：12，191），阴性似然比为 0.21（95%CI：0.12，0.37）。如果结果为阳性和阴性，后验概率分别为 95%和 8%。OSTRC-P 问卷严重程度评分与单腿下降蹲评分之间存在正相关（β=0.08；95%CI：0.03，0.12；P=.001）。
OSTRC-P 问卷是一种可接受的替代临床评估方法，可用于报告青少年篮球运动员的髌腱病并对其严重程度进行分级。
