We aimed to summarize the effectiveness and changing trends of reconstruction for the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) injuries using all-inside arthroscope technique. Between May 2013 and May 2019, 29 patients with ACL and PCL ligaments rupture were included. All the patients were male, with a mean age of 25.2±2.9 years. The mean follow-up period was 2.4±0.7 years (Range, 2-4 years). Reconstruction surgery of the ACL and PCL ligaments was performed by using autologous hamstring tendon with all-inside arthroscopy technique. The anterior and posterior drawer test, Lachman test, Pivot-shift test, stress test, IKDC score, Lysholm score, Tenger score were analyzed clinically. At the last follow-up, the symptoms were improved significantly, the anterior drawer test was normal and 1 degree in 96.6%, posterior drawer test in 89.7%, pivot shift test in 96.6%, Lachman test in 93.1%, and stress test in 93.3%, the stability was improved significant(P<0.05). The IKDC-2000 standard score was normal and near normal in 96.6%. The IKDC subjective score, Lysholm score, and Tenger scores results at the last follow-up were significantly improved when compared with those before operation ( P<0.05). The changing trends of function evaluation score in the first six months were most obviously better, especially in the third month. All-inside arthroscopy technique is an effective procedure for the ACL and PCL ligaments injuries, and the first six months (especially the third month) after the reconstruction is the key period for a successful recovery. However, there was still a significant improvement at the later stage of rehabilitation.
