Abstract
Objective: To evaluate the effectiveness of arthroscopic reconstruction of posterior cruciate ligament (PCL) with embedded "tibial tendon bolt" fixation. Methods: The clinical data of 32 patients who underwent arthroscopic reconstruction of PCL using embedded "tibial tendon bolt" fixation through the tibial "8"-shaped tunnel between February 2012 and April 2016 were analyzed retrospectively. There were 23 males and 9 females, aged 15-57 years (mean, 39.9 years). The causes included traffic accident injury in 12 cases and sports injury in 20 cases. The clinical manifestations were swelling of knee joint, tenderness of knee joint space, and (+) Ⅲ degree in posterior drawer test; McMurry test (+) in 13 cases, valgus stress test (+) in 8 cases, Lachman test (+) in 9 cases, and Dial test (+) in 2 cases. The preoperative Lysholm score was 18.8±10.9, the International Knee Documentation Committee (IKDC) score was 18.0±15.2, and the detection value of KT-1000 was (14.34±2.73) mm. The time from injury to operation was 8-225 days, with a median of 11 days. Results: All 32 patients were followed up 25-36 months, with an average of 26.4 months. The patients had no tenderness of joint space, and the McMurry tests were all (-). At last follow-up, the Lysholm score and IKDC score were 90.2±2.4 and 87.2±6.2, respectively, which were significantly improved when compared with preoperative ones (t=-38.400, P<0.001; t=-27.190, P<0.001). The results of posterior drawer test were (-) in 21 cases, (+) Ⅰ degree in 9 cases, and (+) Ⅱ degree in 2 cases. At 1 and 2 years after operation, the detection value of KT-1000 were (5.56±2.28) mm and (5.87±1.78) mm, respectively, which were significantly improved when compared with preoperative values (P<0.05). Conclusion: The application of arthroscopic reconstruction of PCL using embedded "tibial tendon bolt" fixation through the tibial "8"-shaped tunnel is an effective, simple, and safe surgical procedure.
