[ARTHROSCOPIC TREATMENT OF ANTERIOR CRUCIATE LIGAMENT TIBIAL EMINENCE AVULSION FRACTURE IN ADOLESCENTS WITH EPIPHYSEAL UNCLOSURE].

Abstract

OBJECTIVE:

To evaluate the clinical results of arthroscopic treatment of anterior cruciate ligament (ACL) tibial eminence avulsion fractures in adolescents with epiphyseal unclosure.

METHODS:

Between January 2011 and October 2013, 35 knees with ACL tibial eminence avulsion fractures (35 patients with epiphyseal unclosure) were arthroscopically treated with suture fixation. There were 25 males and 10 females, aged 8-16 years (mean, 14.7 years). The causes included sports injury in 24 cases, traffic accident injury in 9 cases, and daily life injury in 2 cases. According to Meyers-McKeever classification criteria, there were 27 cases of type II and 8 cases of type III. Five cases had meniscus injury. The preoperative the International Knee Documentation Committee (IKDC) score was 48.7 ± 3.2, and Lysholm score was 51.2 ± 4.5. The time from injury to operation was 2-16 days (mean, 5 days).

RESULTS:

Primary healing of incision was obtained in all patients. The mean follow-up time was 22.4 months (range, 12-32 months). Anatomical reduction was achieved in 28 cases and satisfactory reduction in 7 cases. X-ray films showed all fractures healing at last follow-up. There was no limb shortening deformity, varus knee, or valgus knee. Lachman test results were all negative. The other knees had normal range of motion except 1 knee with limited flexion, whose range of motion returned to 0-120° after treatment. At last follow-up, the IKDC score was significantly improved to 93.2 ± 4.1 (t = -53.442, P = 0.000), and the Lysholm score was significantly increased to 96.2 ± 2.5 (t = -56.242, P = 0.000).

CONCLUSION:

The arthroscopic fixation technique has satisfactory results for the reduction and fixation of ACL tibial eminence avulsion fracture in the adolescents with epiphyseal unclosure because of little trauma and quick recovery.
