ObjectiveTo investigate the effectiveness of open reduction by mini incision and absorbable screw internal fixation for the treatment of anterior cruciate ligament (ACL) tibial eminence avulsion fracture.MethodsBetween January 2006 and July 2012, 90 patients (90 knees) with ACL tibial eminence avulsion fracture were treated. There were 58 males and 32 females, aged from 10 to 58 years with an average of 33.7 years. The causes of injury were traffic accident injury in 60 cases, sports injury in 22 cases, and fallinginjury in 8 cases. The disease duration was 1-365 days with a median of 106 days. Combined injuries included 14 cases of meniscus injury, 5 cases of medial collateral ligament injury, and 3 cases of avulsion fracture of the anterior horn of the lateral meniscus. All patients underwent open reduction by mini incision and internal fixation with absorbable screw. Postoperative rehabilitation exercise was performed.ResultsTwo patients had delayed healing of incision, and others obtained primary healing. All the patients were followed up 6-72 months (mean, 40.1 months). X-ray examination showed that bone union was achieved in all patients at 3-12 months after operation; nail tail came off in 7 cases at 4-13 months after operation, and the nail tail was taken out under arthroscopy. At 6-12 months after operation, the range of motion (ROM), Tegner score, Lysholm score, and International Knee Documentation Committee (IKDC) score were significantly increased when compared with preoperative ones (P < 0.05).ConclusionA combination of open reduction by mini incision and absorbable screw internal fixation for the treatment of ACL tibial eminence avulsion fracture has the advantages of easy operation, firm fixation, and satisfactory functional rehabilitation, so it is a safe and effective method for the treatment of ACL tibial eminence avulsion fracture.
