Summary

It could achieve early restoration of knee joint function to treat the anterior cruciate ligament tibial eminence avulsion fracture with suture bridge fixation technique because of satisfactory reduction,reliable fixation minor trauma,and quick recovery.

Abstract

Objective

To evaluate the technique and clinical effect of arthroscopic treatment of anterior cruciate ligament tibial eminence avulsion fracture with suture bridge fixation technique. Methods Between May 2013 and July 2015, 18 patients with anterior cruciate ligament tibial eminence avulsion fracture were treated with arthroscopic reduction and fixation by suture bridge technique.There were 12 males and 6 females with an average age of 29.8 years old (range, 9-45 years).The right knees were involved in 10 cases and left knees in 8 cases.The injury causes included traffic accident injury in 10 cases, sports injury in 5 cases and other reasons in 3 cases. 2 patients had old fracture others had fresh farcture. The results of Lachman and anterior drawer test were both positive. The International Knee Docmentation Committee(IKDC) subject score was 53.8±4.2. Based on Meyers-Mckeaver classification, there were 5 cases in type?, 10 case in type ? and 3 cases in type ?. Results The operation time was 50-80 minutes(mean, 60.5 minutes),X-ray showed satisfactory fracture reduction after surgery.Primary healing of incision were obtained with no infection, all 18 paients were followed up for 6-31 months(mean,18.6 months).The results of Lachman and anterior drawer test were both positive in 17 cases, the result was negative for anterior drawer test and was weakly positive for Lachamn test in 1 case.The IKDC subject score were significanty improved to 95.2±3.8 at last follow-up(P<0.05).Conclusion It could achieve early restoration of knee joint function to treat the anterior cruciate ligament tibial eminence avulsion fracture with suture bridge fixation technique because of satisfactory reduction,reliable fixation minor trauma,and quick recovery.
