[Treatment of acute acromioclavicular joint instability with modern reconstruction procedures]

During the past few years numerous arthroscopic and arthroscopically assisted reconstruction techniques for the stabilization of acute high-grade acromioclavicular joint instability have been adapted either from open procedures or have been made arthroscopically applicable. Currently, pulley-like implants are being used at an increasing rate and the short-term and mid-term clinical and radiological results are at least equal to open techniques.
