INTRODUCTIONTibial eminence fracture is a bony avulsion of the anterior cruciate ligament from its insertion on the anteromedial tibial eminence. 1 These injuries are commonly seen in children aged between 8-14 years and are usually sports related, however in adults these injuries are mainly related to high energy trauma usually road traffic accidents and concomitant injury to the menisci, articular cartilage, and collateral ligaments can also be seen. [2][3][4][5][6][7][8] Meyers and McKeever in 1959 described the severity of the displacement of fracture into 3 types, type I fractures have minimal or no displacement of the fragment, type II fractures have anterior one half avulsion of the eminence, but seated posterior part, and type III fractures have displaced fragment.9 Zaricznyj further modified and divided type III fractures into classes A and B, where type IIIA describes the pathology when the fragment with complete separation is displaced minimally, and type IIIB the pathology when the fragment is twisted or fragmented resulting in rotational malalignment.

ABSTRACTBackground: Several techniques of arthroscopic treatment of tibial spine avulsion fractures have been described in the literature. We conducted a study to analyze the results of arthroscopic assisted wire loop technique for treatment of tibial spine avulsion in adults and pediatric patients. Methods: From June 2011 to December 2016, 52 patients with tibial spine fractures were surgically treated with arthroscopic reduction and wire loop fixation. Forty-four patients were adults and eight were in their pediatric age group. The age group ranged from 9 years to 52 years with the mean age of 26.2 years. 28 patients were type 2 and 24 were of type 3 fracture as classified by Myeres and Mckeever's classification. The final analysis was done using clinical tests, radiological evaluation and International Knee Documentation Committee (IKDC) and Lysholm score. Results: At final follow-up, the mean IKDC and Lysholm knee scores were, 92 and 93 respectively. All patients had a complete functional recovery and were able to return to work and to resume their activities. Conclusions: Arthroscopic wire loop fixation is an excellent method for tibial eminence fracture in adults and children which gives excellent results in form of control tension on ACL on each side of avulsed fragment and also gives adequate mechanical strength for early rehabilitation.
