A system for controlling a relationship between first and second bodiesand made up of a suture assembly with at least a first suture configured todefine arestrictable loop structure with the suture assembly in an operative state. Atleast firstand second restrictable sub-loops cooperatively define a first loop that canbe reducedin size to thereby produce a force on the first and second bodies that urgesthemtowards each other. A first loop length has a first sliding portion with asecond looplength having a second sliding portion. At least one knot extends around thefirst andsecond sliding portions. The first and second sliding portions, upon eachbeing movedwithin the at least one knot in a tightening sliding direction, cause a sizeof a respectivesub-loop to be reduced.
