Abstract:

BACKGROUND: Endobutton CL and Rigidfix system are widely used in anterior cruciate ligament (ACL) reconstruction.
OBJECTIVE: To retrospectively evaluate and compare clinical results between Endobutton CL and Rigidfix fixation systems after ACL reconstruction with autologous quadrupled hamstring tendons.
METHODS: Thirty patients that were treated with arthroscopic ACL reconstruction respectively using hamstring autograft with EndoButton CL system and Rigidfix fixation systems from April 2007 to June 2009 were selected. Patients were evaluated by the anterior drawer test, Lachman test, Pivot shift test, and Lysholm score. ACL reconstruction was performed by one doctor, followed by rehabilitative exercise. The patients were followed up and the follow-up indexes were recorded and compared with preoperative indexes to evaluate improvement of two groups.
RESULTS AND CONCLUSION: The follow-up period of EndoButton CL group was 6 to 26 months, and Lysholm scores were increased from preoperative (56.6±5.9) to postoperative (91.4±4.0), which showed significant differences in t-test (P < 0.05). The follow-up period of Rigidfix group was 6 to 24 months, and Lysholm scores were increased from preoperative (59.2±6.4) to postoperative (93.1±4.7), which showed significant differences in t-test (P < 0.05). There were no significant differences in postoperative Lysholm scores between two groups (P> 0.05). Results demonstrated that Rigidfix and Endobutton fixation device have specific advantages in ACL reconstruction.
