Abstract
AIMS: The present study aims to investigate the clinical outcomes of arthroscopic suture fixation in treating tibial eminence fracture with a retrospective study design of two years' follow-up. METHODS: A total of 33 patients with imaging evidence of tibial eminence avulsion fractures who underwent arthroscopic surgery between 2008 and 2012 were included in this study. The inclusion criteria for the study were a displaced tibial eminence avulsion fracture and anterior knee instability of grade II or higher inskeletally mature patients. These patients were treated with arthroscopic suture fixation and followed with a mean period of 24 months. Anteroposterior and lateral radiographs were obtained 3 months postoperatively to assess fracture healing. At 24 months after surgery, all patients were evaluated by an independent orthopaedic professor with clinical examination like anteroposterior laxity (Lachman-Noulis and anterior drawer tests) and Rolimeter knee tester (Aircast, Vista, CA). Knee range of motion was evaluated actively and passively with a goniometer. Knee function was evaluated by the Lysholm and International Knee Documentation Committee (IKDC) scores. Knee radiographs in standing anteroposterior, standing lateral, and Merchant views were examined for alignment, joint space narrowing, and degenerative knee changes. RESULTS: No major complication like infection, deep venous thrombosis, or neurovascular deficit happened peri-operatively. At the final follow-up, there were no symptoms of instability and no clinical signs of ACL deficiency. Radiographs showed that all fractures healed 3 months post-operative, but at the last follow-up, there was one person with degenerative changes like joint space narrowing in radiographs. Anterior translation of the tibia was 0.47 mm on average (0 to 2.5 mm) compared with the uninjured side. Range-of-motion measurement showed a mean extension deficit of 1.5° (0° to 5°) and a mean flexion deficit of 2.7° (0° to 10°) compared with the unaffected side. The mean Lysholm score was 96 (85 to 100), and the mean IKDC score was 94 (80 to 100). Overall, the IKDC grade was A (normal) in 24 patients (58%), B (nearly normal) in 8 patients (33%), and C (abnormal) in 1 patient (8%). CONCLUSION: The present study demonstrated tibial eminence fractures in adults can be effectively treated with arthroscopic suture fixation.
