The gracilis tendon is a commonly used autologous graft. Most information on knee function and outcomes after its harvest is related to both semitendinosus- and gracilis tendon harvest. Therefore this study analyzed the effect of isolated gracilis tendon harvest from healthy, uninjured knees on thigh muscle strength and patient reported outcome measures (PROMs).
Stabilization of the acromioclavicular joint because of chronic instability was performed with autologous gracilis tendon in 12 patients. After a mean of 44 ± 25 months after surgery, isokinetic peak-torque measurements of specific functions of the gracilis muscle were performed: knee flexion in a sitting position (flexion angles 0-90°) and in prone position (flexion angles > 70°), internal tibial rotation and hip adduction. The contralateral limb was control. Knee specific PROMs were collected including IKDC-2000 subjective evaluation form, Lysholm score, the Marx Activity Rating Scale and SF-36 health survey.
No significant side-to-side differences were found regarding torque measurements. Excellent results were shown regarding the PROMs, which even in terms of IKDC-2000 (97 vs. 82 points, p = 0.001) exceeded significantly the age- and gender matched reference-data.
Isolated gracilis tendon harvesting was not associated with loss of strength in knee flexion, internal tibial rotation and thigh adduction. Additionally, good functional outcome as well as excellent knee-specific subjective outcome was found.

股薄肌腱是一种常用的自体移植物。大多数关于膝关节功能和术后结果的信息都与半腱肌和股薄肌腱的采集有关。因此，本研究分析了从健康、未受伤的膝关节中采集单纯股薄肌腱对大腿肌肉力量和患者报告的结果测量（PROM）的影响。
12 例患者因慢性不稳定而行自体股薄肌腱固定肩锁关节。术后平均 44 ± 25 个月后，对股薄肌特定功能进行等速峰值扭矩测量：坐姿膝关节屈曲（屈曲角度 0-90°）和俯卧位（屈曲角度 > 70°）、胫骨内旋和髋关节内收。对侧肢体作为对照。收集膝关节特定的 PROM，包括 IKDC-2000 主观评估表、Lysholm 评分、Marx 活动评分量表和 SF-36 健康调查。
在扭矩测量方面，没有发现明显的侧-侧差异。在 PROM 方面，结果非常好，即使在 IKDC-2000 方面（97 分比 82 分，p=0.001）也明显超过了年龄和性别匹配的参考数据。
单纯股薄肌腱采集不会导致膝关节屈曲、胫骨内旋和大腿内收力量丧失。此外，还发现了良好的功能结果和出色的膝关节特异性主观结果。
