Quadriceps tendon ruptures are uncommon injuries. Degenerative changes in the tendon are felt to be an important precondition for rupture. We retrospectively reviewed 45 quadriceps tendon ruptures in 42 patients. Quadriceps tendon ruptures occurred most often in the sixth and seventh decade of life. Men were affected six times as often as women. A tissue sample from the rupture-zone was obtained in 22 cases and histologic analysis was performed. Degenerative changes were present in only 14 (64%) of the 22 samples. We observed an increasing ratio of degenerative to nondegenerative tendons with increasing patient age. Our data suggests that quadriceps tendon rupture, especially in younger patients, can occur in the absence of pathologic tendon degeneration.
四头肌腱断裂是不常见的损伤。肌腱的退行性变化被认为是断裂的重要前提条件。我们回顾性分析了 42 例 45 例四头肌腱断裂患者。四头肌腱断裂最常发生在第六和第七个十年。男性比女性受影响的几率高六倍。在 22 例中获得了断裂区的组织样本，并进行了组织学分析。仅在 14 例（64%）样本中存在退行性改变。我们观察到随着患者年龄的增加，退行性肌腱与非退行性肌腱的比例增加。我们的数据表明，尤其是在年轻患者中，四头肌腱断裂可在无病理肌腱退变的情况下发生。
