[Arthroscopic reduction and utilization of Suture Bridge tech reconstructing footprint area structure for the treatment of anterior cruciate ligament avulsion fracture].

OBJECTIVE

To evaluate the preliminary curative effect of arthroscopic reduction and utilization of Suture Bridge tech reconstructing footprint area structure for anterior cruciate ligament avulsion fracture.

METHODS

From March 2010 to September 2012, 6 patients suffered anterior cruciate ligament avulsion fracture were treated with arthroscopic Suture bridge fixation for anterior cruciate ligament tibial side footprint reconstruction. There were 2 males and 4 females, ranging in age from 14 to 52 years old. There were 2 cases of type III and 4 cases of type IV displaced fractures classified by Meyers-McKeever-Zaricznyj. Preoperative ADT and Lachman tests were positive.

RESULTS

All the patients was follow up more than 2 years. Postoperative ADT and Lachman tests were negative without limitation of knee extension. Postoperative X ray and MRI showed that displaced fracture with a good reduction and union, recovered normal shapeness of ACL. The postoperative Lysholm and IKDC scores at different time points(3 months, 1 year, 2 years after operation) improved significantly comparing with preoperative, and the differences were statistically significant (<0.01).

CONCLUSIONS

Suture Bridge tech reconstructing footprint area structure for ACL avulsion fracture is an effective and safe method, especially for adolescent patients with unclosed epiphysis and comminuted avulsion fracture.
