Poly-L-lactic tack leads to visibly larger drill holes in shoulder fixation .
A 7-Year Prospective, Randomized, Clinical, and Radiographic Study After Arthroscopic Bankart Reconstruction Using 2 Different Types of Absorbable Tack
Am J Sports Med. 2009 Oct;37(10):1930-7. Epub 2009 May 29.40 patients who had recurrent shoulder instability were randomized to receive Bankart reconstruction using either polygluconate-B polymer (PGA) tacks or self-reinforced poly-L-lactic (PLLA) tacks. This study assessed clinical and radiographic results of Bankart reconstruction with these two implants. The results from this study indicated that clinical outcomes were not significantly different at 7 year follow-up. It should be noted that the drill holes in the PLLA group were significantly more visible at a 7 year follow-up.
