Strength data can help in guiding the return to sports (RTS) process in patients after an anterior cruciate ligament reconstruction (ACLR). There is need for a fast, cheap, and portable method to monitor muscle strength in patients after ACLR in an ambulatory stetting. Therefore, the purpose of the current study was to assess the use of a hand-held dynamometer (HHD) to monitor hamstring and quadriceps strength after ACLR and to assess the changes over time in patients tested at 3, 6 and 9 months after ACLR. It was hypothesized that patients show greater muscle strength at 6 months after ACLR compared to 3 months, and at 9 months after ACLR compared to 6 months. Forty-four amateur athletes (n = 44) after ACLR participated. Isometric hamstring and quadriceps strength were measured with a HHD at three time points during rehabilitation. Absolute isometric hamstring strength significantly progressed over time. Similar, absolute isometric quadriceps strength significantly progressed over time. This study showed that using handheld dynamometry can be a simple method to monitor the development of absolute isometric hamstring and quadriceps strength in patients after ACLR.

力量数据有助于指导前交叉韧带重建（ACLR）术后患者的恢复运动（RTS）过程。需要一种快速、廉价且便携的方法，在门诊环境中监测ACLR术后患者的肌肉力量。因此，本研究的目的是评估使用手持测力计（HHD）监测ACLR术后患者的腘绳肌和股四头肌力量，并评估在ACLR术后3个月、6个月和9个月接受测试的患者随时间的变化。研究假设是，与ACLR术后3个月相比，患者在术后6个月时肌肉力量更大，与术后6个月相比，在术后9个月时肌肉力量更大。44名ACLR术后的业余运动员参与了研究。在康复过程中的三个时间点，使用HHD测量等长腘绳肌和股四头肌力量。绝对等长腘绳肌力量随时间显著改善。同样，绝对等长股四头肌力量也随时间显著改善。本研究表明，使用手持测力计可以作为一种简单的方法，来监测ACLR术后患者绝对等长腘绳肌和股四头肌力量的发展。
