Abstract
BACKGROUND
The tibial stop of anterior cruciate ligament (ACL) is fan-shaped and attached to the medial groove in front of the intercondylar spine, which is located between the anterior horn of the medial and lateral meniscus. The incidence of this fracture is low previously reported, which is common in children and adolescents. With the increase of sports injury and traffic injury and the deepening of under-standing, it is found that the incidence of the disease is high at present.
AIM
To explore the difference between open reduction and internal fixation with small incision and high-intensity non-absorbable suture under arthroscopy in the treatment of tibial avulsion fracture of ACL.
METHODS
Seventy-six patients with tibial avulsion fracture of anterior cruciate ligament diagnosed and treated in Guanyun County People's Hospital from April 2018 to June 2020 were retrospectively analyzed. According to the surgical methods, they were divided into group A (40 cases) and group B (36 cases). Patients in group A were treated with arthroscopic high-strength non-absorbable suture, and patients in group B were treated with small incision open reduction and internal fixation. The operation time, fracture healing time, knee joint activity and functional score before and after operation, and surgical complications of the two groups were compared.
RESULTS
The operation time of group A was higher than that of group B, and the difference was statistically significant (P < 0.05); the fracture healing time of group A was compared with that of group B, and the difference was not statistically significant (P > 0.05); The knee joint function activity was compared between two groups before operation, 3 mo and 6 mo after operation, and the difference was not statistically significant (P > 0.05); the knee joint function activity of group A and group B at 3 mo and 6 mo after operation was significantly higher than that before operation (P < 0.05); the limp, support, lock, instability, swelling, upstairs, squatting, pain and Lysholm score were compared between the two groups before and 6 mo after operation, and the difference was not statistically significant (P > 0.05); the scores of limp, support, lock, instability, swelling, upstairs, squatting, pain and Lysholm in group A and group B at 6 mo after operation were significantly higher than those before operation (P > 0.05); the surgical complication rate of group A was 2.63%, which was lower than 18.42% of group B, and the difference was statistically significant (P > 0.05).
CONCLUSION
Both small incision open reduction and internal fixation and arthroscopic high-strength non-absorbable sutures can achieve good results in the treatment of anterior cruciate ligament tibial avulsion fractures. The operation time of arthroscopic high-strength non-absorbable sutures is slightly longer, but the complication rate is lower.
