title: Acromioclavicular reconstruction using hook plate and anterior tibial tendon allograft with triple tunnel: The early results of revision surgery using a novel surgical technique.
abstract: In this study, a new modified surgical technique is presented for anatomic acromioclavicular (AC) joint reconstruction made by the application of anterior tibialis tendon autograft, three-way tunnel (two clavicular and one coracoid) and hook plate. The study is aimed to evaluate the post-operative short-term results of patients who underwent this treatment. A total of 11 patients underwent AC joint reconstruction because of persistent AC subluxation. In this reconstruction, a triple tunnel was made between the coracoid and the clavicle to anatomically restore the coracoclavicular (CC) ligament and an allograft was passed through the tunnels resembling conoid and trapezoid ligaments. The tendon had to be non-weight bearing at the appropriate tension to provide rapid and appropriate integration of the tendon in the tunnel. This was maintained by applying a hook plate. The hook plate method was used to protect the reconstructed ligament during the healing process as it has a similar hardness to that of the natural AC joint and provides rigid fixation. For a more comprehensive description of the technique, a cadaver demonstration was also performed. The mean follow-up period was 25.3 months (range: 18-34 month). None of the patients had a loss of reduction at the final follow-up. When the constant scores were examined, of the total 11 patients, 2 (18.2%) 38,39 had excellent results, 6 (54.5%) had good results and 3 (27.3%) had fair results. It can be seen that this newly described reconstruction technique has successful short-term results as an anatomic method and can be used effectively in revision cases. However, there is a need for further biomechanical and clinical studies to make comparisons with other techniques.
