How should we define failure after surgical shoulder stabilization?

If 2 alternating half-hitches are required to back up the SPK, it is more time-consuming to tie than the SMC and Revo knots and potentially stacks higher, thus eliminating 2 of its most attractive features. Ultimately, our goal was to test the SPK in a manner that could be safely translated into our clinical practice. In our study we determined that the SPK tied with a single backup half-hitch is a clinically safe, efficient, and low-profile knot that is useful in our practice.
