ObjectiveTo explore the method and curative effect of double bundle reconstruction of posterior cruciate ligament with total internal short tendon technique.MethodsFrom October 2010 to June 2018, 50 patients with simple posterior cruciate ligament rupture were admitted, including 35 males and 15 females, ranging in age from 20 to 45 years old, 16 with acute injury and 34 with old injury. The posterior cruciate ligament (PCL) was reconstructed by double bundle technique with the whole internal short tendon. The two ends of the transplanted ligament were fixed by titanium plate suspended with adjustable loop. The Lysholm knee score and IKDC score were used to evaluate the clinical effects.ResultsAll the 50 patients were followed up, and the duration ranged from 6 to 60 months, with a mean of (28.84±9.52) months. At the latest follow up, the knee joint activity returned to normal range. The median value of Lysholm knee score was 54 before operation and 100 after operation. According to the IKDC score, there were 0 case of grade A, 0 case of grade B, 20 cases of grade C and 30 cases of grade D before operation;29 cases of grade A, 19 cases of grade B, 1 case of grade C and 1 case of grade D after operation;the difference was statistically significant (P<0.01).ConclusionArthroscopic double bundle reconstruction of posterior cruciate ligament with short internal tendon is safe and reliable, with less tendon transplantation, more stable fixation, and more bone reserve, which is beneficial for healing and renovation. The short term effect is positive.
