Symptoms of jumper's knee (patellar tendinosis) are not easily quantified and this may explain why there are no evidence-based guidelines for managing the condition. A simple, practical questionnaire-based index of severity would facilitate jumper's knee research and subsequently, clinical management. Thus we devised and tested the Victorian Institute of Sport Assessment (VISA) questionnaire. The brief questionnaire assesses (i) symptoms, (ii) simple tests of function and (iii) ability to play sport. Six of the eight questions are scored on a visual analogue scale from 0-10 with 10 representing optimal health. The maximal VISA score for an asymptomatic, fully performing individual is 100 points and the theoretical minimum is 0 points. We found the VISA scale to have excellent short-term test-retest, and inter-tester reliability (both, r>0.95) as well as good short-term (one week) stability (r=0.87). Mean (SD) of the VISA scores ranged from 95 (8) points in asymptomatic control subjects to 55 (12) points in patients who presented to a sports medicine clinic with jumper's knee and 22 (17) points in patients before surgery for chronic jumper's knee. Six- and twelve-months after surgery VISA scores returned to 49 (15) and 75 (17) points respectively, mirroring clinical recovery. We conclude that the VISA score is a reliable index of the severity of jumper's knee that has potential to aid clinicians and researchers.
跳跃膝（髌腱病）的症状不易量化，这或许可以解释为何目前尚无基于证据的该病管理指南。一个简单、实用的基于问卷的严重程度指数将有助于跳跃膝的研究以及后续的临床管理。因此，我们设计并测试了维多利亚运动评估协会（VISA）问卷。这份简短的问卷评估了：（i）症状，（ii）简单的功能测试，以及（iii）运动能力。八个问题中的六个在0至10的视觉模拟量表上计分，10分代表最佳健康状态。无症状、功能完全正常个体的VISA最高得分是100分，理论最低分是0分。我们发现VISA量表具有出色的短期重测信度和测试者间信度（两者r>0.95），以及良好的短期（一周）稳定性（r=0.87）。VISA得分的均值（标准差）范围从无症状对照组的95（8）分，到因跳跃膝前往运动医学诊所就诊患者的55（12）分，以及慢性跳跃膝患者术前的22（17）分。术后6个月和12个月，VISA得分分别恢复到49（15）分和75（17）分，反映了临床恢复情况。我们得出结论，VISA得分是跳跃膝严重程度的可靠指标，有潜力帮助临床医生和研究人员。
