Abstract:

Objective To investigate the clinical effects of knee arthroscopic reconstruction of anteriorcruciate ligament（ACL）with RigidFix and RigidLoop. Methods From June 2016，121 patients with ACL ruptureunderwent anterior cruciate ligament reconstruction with Rigidfix or Rigidloop under total arthroscopy. patientsThey volunteered to be randomly divided into two groups：Rigidfix group（n = 61）and Rigidloop group（n = 60）.The ACL ruptures in the two groups were diagnosed preoperatively by MRI，without significant difference inLysholm score between the Rigidfix group and Rigidloop group［（49.5 ± 6.5）vs.（48.9 ± 6.7），P > 0.05］. Results All of the patients were followed up for（27.9 ± 3.5）months. At the end of follow⁃up，the Lysholm scores of theRigidfix and Rigidloop group were（91.7 ± 3.9）and（91.5 ± 3.8），respectively. The IKDC scores of the Rigidfixgroup were normal and close to normal in 58 cases，abnormal in 2 cases，much more abnormal in 1 case，with anexcellent rate of 95.1%，and the IKDC scores of the Rigidloop group were normal and close to normal in 56 cases，abnormal in 3 cases and much more abnormal in 1 case with an excellent rate of 93.3%. There were no significantdifferences between the two groups（P > 0.05）. Conclusion Both RigidFix and RigidLoop under total arthroscopycan achieve anatomical reconstruction and stability of knee joints of patients with ACL ruptures.
