Patellar tendon injury, a chronic overuse injury characterised by pain during tendon loading, is common in volleyball players and may profoundly restrict their ability to compete. This cross-sectional study investigated the association between performance factors and the presence of patellar tendon injury. These performance factors (sit and reach flexibility, ankle dorsiflexion range, jump height, ankle plantarflexor strength, years of volleyball competition and activity level) were measured in 113 male and female volleyball players. Patellar tendon health was determined by measures of pain and ultrasound imaging. The association between these performance factors and patellar tendon health (normal tendon, abnormal imaging without pain, abnormal imaging with pain) was investigated using analysis of variance. Only reduced ankle dorsiflexion range was associated with patellar tendinopathy (p<0.05). As coupling between ankle dorsiflexion and eccentric contraction of the calf muscle is important in absorbing lower limb force when landing from a jump, reduced ankle dorsiflexion range may increase the risk of patellar tendinopathy.
髌腱损伤是一种慢性过度使用损伤，其特征是在肌腱负荷时出现疼痛，在排球运动员中很常见，可能会严重限制他们的比赛能力。这项横断面研究调查了运动表现因素与髌腱损伤之间的关联。在113名男女排球运动员中测量了这些运动表现因素（坐立前屈灵活性、踝关节背屈范围、跳跃高度、踝关节跖屈肌力量、排球比赛年限和活动水平）。通过疼痛测量和超声成像来确定髌腱健康状况。使用方差分析研究了这些运动表现因素与髌腱健康状况（正常肌腱、无疼痛的异常成像、有疼痛的异常成像）之间的关联。只有踝关节背屈范围减小与髌腱病相关（p<0.05）。由于踝关节背屈与小腿肌肉离心收缩之间的耦合在从跳跃着陆时吸收下肢力量方面很重要，踝关节背屈范围减小可能会增加髌腱病的风险。
