However, when the analyzed outcome was treatment failure during surgery, despite the absence of statistical significance (RR = 0.52; CI: 0.1794–1.3122; p = 0.1542), there was a clear trend in favor of the interference screw, which presented fewer failures in all retrieved studies. 40 Those authors suggested that a close fixation of the joint may be biomechanically favorable. 45 Similarly, Saccomanno et al. 46 conducted a systematic review (level 1) and compared the suspensory fixation (Endobutton) with fixation in the buttress position (transverse pin).
