Abstract:

BACKGROUND: Arthroscopic reconstruction of anterior cruciate ligament (ACL) is the golden standard for injured anterior cruciate ligament. However, it remains controversial in tendon fixation pattern.
OBJECTIVE: To evaluate clinical effects of arthroscopic ACL reconstruction by using hamstring autograft with femoral fixation via Rigidfix, Endobutton system and tibial fixation via Intrafix system.
METHODS: Thirty cases of patients were chosen from Department of Joint Surgery, First Affiliated Hospital of Zhengzhou University (2009-05 to 2010-05), which had been treated with arthroscopic ACL reconstruction by using hamstring autograft with femoral fixation via Endobutton, Rigidfix system and tibial fixation via Intrafix system. They all had been identified as ACL injure or ligament ruptures in arthroscopy. They were in a age range of 16 to 45, and twenty-two males with eight females. The femoral fixation was via Endobutton, Rigidfix system and tibial fixation via Intrafix system. The short-term effectiveness was observed postoperatively and knee function was evaluated by Lysholm and IKDC systems.
RESULTS AND CONCLUSION: All 30 patients were followed up for 5-17 months (12 months on average), during when there were no severe complications and all injured knee-joints were with a normal mobility. Lysholm and IKDC systems showed that the scores ascended respectively from (50.0±6.0) before surgery to (85.5±3.5) and (49.5±5.5) to (87.0±2.5) (P < 0.05). These all indicates that this method of Rigidfix and Endobutton femoral fixation device, Intrafix tibial fixtaion device in arthroscopic reconstruction of ACL using autografts of hamstring tendon owns many advantages such as good short-term effectiveness, reliable graft fixation and less complications, which gets a good clinical recovery effectiveness.
