Reconstruction is the method of choice in the treatment of ACL rupture. Postoperative rehabilitation is a very important aspect of therapeutic management. One of priority elements is to regain proper strength and function of the quadriceps muscle in a short time. The aim of this study was to estimate the dynamics of the increase in strength and girth of quadriceps after ACL reconstruction.
The examined group consisted of 30 patients who had undergone arthroscopic assisted quadruple bundle dual channel ACL reconstruction surgery in years 2010-2011. The average age of the patients at the time of operation was 31.7 years (range 17-53). Each patient was examined 4 times: before the surgery as well as in the second, sixth and twelfth week after the reconstruction.
Examination revealed a significant increase in quadriceps girth, with peak increase rate observed within the two first weeks after the surgery. Between weeks 2 and 6, a decrease in quadriceps girth was observed followed by repeated increase worm week 6 on. The greatest increase in the girth at the thickest point of the muscle was observed in rehabilitation weeks 6 through 12. A significant decrease in muscle strength was observed in the first 2 weeks after the surgery. In the remaining periods, the strength of the quadriceps muscle continued to grow. The average KSS score increased from 109.1 at week 2 to 162.3 at week 12 after the surgery.
Rehabilitation results in a dynamic increase in the strength of quadriceps between weeks 6 and 12 following reconstruction of anterior cruciate ligament. However, the 12-week rehabilitation period is not sufficient to regain full functionality.
重建是治疗前交叉韧带（ACL）断裂的首选方法。术后康复是治疗管理中非常重要的一个方面。优先事项之一是在短时间内恢复股四头肌的正常力量和功能。本研究的目的是评估ACL重建术后股四头肌力量和围度增加的动态变化。
研究组由30例在2010 - 2011年接受关节镜辅助四束双通道ACL重建手术的患者组成。手术时患者的平均年龄为31.7岁（范围17 - 53岁）。每位患者接受4次检查：手术前以及重建后的第2周、第6周和第12周。
检查发现股四头肌围度显著增加，术后前两周内增加速率达到峰值。在第2周和第6周之间，股四头肌围度出现下降，随后从第6周开始再次增加。在康复的第6周至12周期间，观察到肌肉最厚点的围度增加最大。术后前两周肌肉力量显著下降。在其余时间段，股四头肌力量持续增长。术后第2周平均KSS评分为109.1，第12周增至162.3。
前交叉韧带重建术后第6周至12周，康复可使股四头肌力量动态增加。然而，12周的康复期不足以恢复全部功能。
