hi, this is a device which outperforms tightrope, and has no patent issues. this is the video of the knot and how it works. test results- slippage of 0.16 mm after 1000 plus cycles. Tightrope slips about 2 mm as per their study. Load to failure is 866 N after 2000 cycles , (at which the knot breaks) . Tightrope breaks at 876. It easily outperforms tightrope both in graft protection and locking security. Simple to make . No patent infringement. Here's the YouTube link. http://m.youtube.com/watch?v=QHCTpo_FGRQ
Why would I need anything to outperform tightrope? The pos loosens before the patient is out of the OR. The next ACL business I lose to tightrope will be the first.
