A simple modified arthroscopic procedure for fixation of displaced tibial eminence fractures.

SUMMARY: Avulsion fractures of the tibial eminence have been well described in children and adults with an increased in incidence resulting from road traffic and athletic accidents. According to the literature, only surgical treatment is advocated because of the high incidence of the nonunion and instability following conservative treatment. Open reduction can cause some morbidity and, therefore, arthroscopic techniques have been developed. The limitations of the techniques are related to technical difficulty and unstable fixation. We report a simple and effective method of fixation with the following advantages: (1) use of metallic suture for stable fixation, (2) the fixation device is easily removed in the office, (3) there is no need of additional instruments, and (4) the minimal size of the fixation device avoids damage to the anterior cruciate ligament insertion. This technique has been used in a series of 10 consecutive patients treated for avulsion fractures of the tibial spine since 1991, resulting in a high rate of excellent and good results without any case of nonunion fracture or related complication.
