Purpose:To analyze the clinical result of the arthroscopic reduction and fixation for the displaced tibial spine fractures in children and report the utility of the arthroscopic treatment with the review of the literature.
Materials and Methods:Between December 2000 and July 2004, five patients (average age 9.1 years) received an arthroscopic reduction and fixation of displaced tibial spine fracture. A male-to-female ratio was 3:2 and mean follow-up was 38. (13~56) months. All five patients were classified typeⅢ by Meyers and McKeever classification. The average period from injury to operation was 4.8 days (3~8days), the avulsed fragment was reduced by operative arthroscopy and fixated by pull-out suture in 3 patients and by cannulated screw in 2 patients. Postoperatively long leg cast was applied for 2 weeks, and then gradual range- f-motion exercise was permitted. Full weight-bearing ambulation was permitted after 6 weeks. The clinical evaluation was performed by range of motion, Lachman and pivot shift test, KT-1000 arthrometer, Lysholm knee score and the modified Feagin score.
Results: All five patients had no symptom and recovered full range of motion of the affected knees. Lachman test was positive finding of 1+ laxity in one patient, the others were negative, and all patients were negative findings for pivot shift test. The result of KT-1000 arthrometric assessment is mean maximum side-to-side differences 1.9 mm. Average Lysholm knee score was 99.4. All patients had excellent results in modified Feagin score.
Conclusion:Arthroscopic reduction and fixation of displaced tibial spine fracture in children showed excellent result without complication. Both pull-out suture fixation and cannulated fixation provide an effective treatment option for fixation of the displaced anterior tibial spine fracture.
