病例控制。旨在检查患有髌腱病 (PT) 的患者是否比没有 PT 的患者表现出更大的髌骨活动度和不同的下半身运动学。 PT 是一种常见的髌腱过度使用状况，可导致疼痛和功能损害。患有膝关节过度使用问题的受试者表现出不同的髋部和膝部功能力学，特别是外翻塌陷。尚未将髌骨过度活动作为 PT 的可能危险因素进行专门研究。研究对象为 11 名患有 PT 的患者和 11 名年龄在 18 岁至 40 岁之间未患有 PT 的对照者。使用髌股关节计（PFA）测量最大外侧和内侧髌骨位移。进行 3D 运动分析以确定单腿下台阶和垂直跳跃测试期间下肢关节的运动。与对照组相比，PT 患者的髌骨外侧活动度显着增加（12.21 ± 3.33 mm vs. 9.19 ± 1.92 mm，P = .017）。 PT 患者在垂直跳跃（2.7° ± 6.3° 与 -5.6° ± 4.2°；P = .003）和下降（17.0° ± 3.8° 与 12.5° ± 4.4°，P = .024）方面均表现出明显更大的髋部内收峰值。 PT 患者表现出踝关节外旋峰值增加，同时垂直跳跃下降（−21.1° ± 5.9° 与 -14.8° ± 5.5°，P = .023）和下降（−15.6° ± 5.5° 与 -9.0° ± 6.0°，P = .017）。 PT 患者表现出髌骨外侧活动度、髋内收和踝外旋能力增强。髌骨活动度增加对 PT 的发生、治疗和预防的影响值得进一步研究。
Case-control. To examine whether patients with patellar tendinopathy (PT) display greater patellar mobility and different lower body kinematics than patients without PT. PT is a common overuse condition of the patellar tendon that can cause pain and impair function. Subjects with overuse knee problems display different hip and knee functional mechanics, specifically valgus collapse. Patellar hypermobility has not been specifically studied as a possible risk factor for PT. 11 patients with PT and 11 controls without PT, age 18 to 40, were studied. Using a patellofemoral arthrometer (PFA), maximal lateral and medial patellar displacement was measured. 3-D motion analysis was performed to determine lower extremity joint motions during single-leg step down and drop vertical jump tests. Patients with PT had significantly increased lateral patellar mobility compared to controls (12.21 ± 3.33 mm vs. 9.19 ± 1.92 mm, P = .017). PT patients showed significantly greater peak hip adduction with both drop vertical jump (2.7° ± 6.3° vs. −5.6° ± 4.2°; P = .003) and step down (17.0° ± 3.8° vs. 12.5° ± 4.4°, P = .024). PT patients demonstrated increased peak ankle external rotation with drop vertical jump (−21.1° ± 5.9° vs. −14.8° ± 5.5°, P = .023) and step down (−15.6° ± 5.5° vs. −9.0° ± 6.0°, P = .017). Patients with PT exhibit increased lateral patellar mobility, hip adduction, and ankle external rotation. The effects of increased patellar mobility deserve further study in the development, management, and prevention of PT.
