Background

In Professional Athletes, quadriceps and patellar tendon ruptures are devastating injuries, often resulting in the loss of a season or a decreased return to the pre-injury level of sport. This study aimed to perform a comprehensive Video Analysis on extensor mechanism rupture (EMR) to describe the body postures and related mechanism in Professional Athletes.

Methods

Using publicly available data on quadriceps tendon and patellar tendon ruptures from between 2000 and 2020, 52 elite athletes were identified. Of these, twenty-eight injuries with adequate video data were analyzed for Injury Mechanism, body posture, as well as player and sports characteristics.

Results

Of the 27 athletes included in the study, with an average age of 28.18 ± 4.96 years, there were injuries in 28 extremities (1 case bilateral). The patellar tendon was ruptured in 20 cases (71.4%), and the quadriceps tendon in 8 cases (28.6%). There was total tendon rupture in 13 cases, and partial rupture in 6 cases (data for 1 case was not available). In 20 cases (70.4%), there was no contact resulting in the injury. Four of the contact injuries occurred in American football (3 direct, one indirect), 3 in basketball (1 direct, two indirect), and 1 in baseball (direct).

Conclusion

The results of this research indicate that EMR occurs most commonly when the knee is in flexion and the ankle is in plantar flexion. There is the tendency for the knee to be in valgus at the time of injury. This information can guide physical therapy techniques, including neuromuscular training, proprioception, and balance training in the prevention of EMR in elite athletes.

职业运动员膝关节伸肌机构断裂的损伤机制：视频分析研究

背景

在职业运动员中，股四头肌和髌腱断裂是毁灭性的伤害，通常会导致赛季失败或恢复到受伤前运动水平的能力下降。本研究旨在对伸肌机制断裂（EMR）进行全面的视频分析，以描述职业运动员的身体姿势和相关机制。

方法

利用 2000 年至 2020 年间股四头肌腱和髌腱断裂的公开数据，确定了 52 名精英运动员。其中，对 28 例具有足够视频数据的损伤进行了损伤机制、身体姿势以及运动员和运动特征的分析。

结果

研究纳入的27名运动员中，平均年龄为28.18±4.96岁，有28个肢体受伤（1例双侧）。髌腱断裂20例（71.4%），股四头肌腱断裂8例（28.6%）。肌腱完全断裂13例，部分断裂6例（1例资料不明）。20例（70.4%）并非因接触造成伤害。其中 4 起接触伤害发生在美式橄榄球比赛中（3 起直接伤害，1 起间接伤害），3 起发生在篮球比赛中（1 起直接伤害，2 起间接伤害），以及 1 起发生在棒球比赛中（直接）。
