To examine potential intrinsic risk factors that may contribute to the onset of jumper's knee in elite level-male volleyball players.
Prospective Cohort Study.
Varsity and National team volleyball gymnasiums.
Sixty elite adult male volleyball players from Canada.
Players completed a series of risk factor assessments at the commencement of their seasons, including vertical jump (cm), ankle dorsiflexion range (degrees), dynamic balance (normalized distance reached; cm), dynamic knee alignment (degrees), and landing mechanics (degrees).
Self-reported knee problems, captured via short message service.
Knee problem prevalence was 75% [95% confidence intervals (CIs): 62.2-84.6] and the incidence rate for substantial injuries over the study period was 30 injuries/100 players/season (95% CI: 19.5-43.1). No risk factor was found to significantly predict the future occurrence of developing jumper's knee. The odds ratios were close to unity (range: 0.94-1.07) with narrow confidence intervals and P > 0.05.
A more sensitive capture of overuse knee problems did not result in the identification of distinct risk factors for the development of jumper's knee. These findings highlight a lack of available methodology to accurately assess risk factors for overuse injuries.
研究可能导致精英水平男性排球运动员发生跳跃膝的潜在内在风险因素。
前瞻性队列研究。
大学和国家队排球场馆。
60名来自加拿大的精英成年男性排球运动员。
运动员在赛季开始时完成了一系列风险因素评估，包括垂直跳跃（厘米）、踝关节背屈范围（度）、动态平衡（达到的标准化距离；厘米）、动态膝关节对线（度）和落地力学（度）。
通过短信收集的自我报告的膝盖问题。
膝盖问题患病率为75%[95%置信区间（CI）：62.2 - 84.6]，研究期间严重损伤的发生率为30例损伤/100名运动员/赛季（95%CI：19.5 - 43.1）。未发现有风险因素能显著预测未来跳跃膝的发生。优势比接近1（范围：0.94 - 1.07），置信区间狭窄，P>0.05。
对过度使用导致的膝盖问题进行更敏感的捕捉，并未识别出跳跃膝发生的明显风险因素。这些发现凸显了缺乏准确评估过度使用损伤风险因素的可用方法。
