Abstract
Tibial eminentia fractures are avulsion fractures of the anterior cruciate ligament caused with additional injuries like meniscus tears or ligamentous injuries. Arthroscopic assisted internal fixation has become a preferred technique with the development of arthroscopic techniques. We aimed to present our results for arthroscopic assisted double tibial tunnel fixation in patients with displaced eminentia fracture. Twenty patients who were operated on for eminentia fracture between January 2010 and May 2014 were included in this study. All fractures were type II according to Meyers's classification. Eminentia was reduced with two nonabsorbable sutures through the ACL. Two tibial tunnels were created over the medial proximal tibia with a 2.4 mm cannulated drill. The two suture ends taken out of the 2 tibial tunnels were connected on the bone bridge between the tunnels. Patients were evaluated with Lysholm score, Tegner score, IKDC score and examined for clinical and radiological evidence of bony union. Quadriceps exercises were started on the third day. The patients were followed up with a locked knee brace in extension for 3 weeks after surgery and later patients were encouraged to mobilize as pain allowed. The preoperative Lysholm score was 75 ±3.3 and the postoperative Lysholm score was 94.5 ±3. Tegner score was 3.52±1.02 preoperatively and 6.84±1.099 postoperatively. International Knee Documentation Committee(IKDC) score was abnormal in all of the 20 patients preoperatively but normal postoperatively. The postoperative scores of the patients were statistically significant when compared with preoperative activity scores(p<0,0001). Tibial eminentia fractures may lead to pain, knee instability, malunion, laxity, or extension deficit. The technique we have described together with early rehabilitation may give good clinical results.
