1. A system comprising:
an implant system including:
an anchor configured to be secured in bone beneath a patient's articular surface, said anchor having an inner passageway therethrough;
and
an implant configured to be secured to said anchor, said implant configured to replace a portion of said patient's articular surface;
a suture having a first portion configured to be disposed around an exterior portion of said anchor, such that said suture is spaced apart from the inner passageway; and
an implant delivery system comprising:
a driver including a shaft; and
a biasing body having a first end region configured to engage said driver, a second end region configured to engage a portion of said implant;
wherein a second portion of said suture is configured to extend from said exterior portion of said anchor to interface with said driver, such that said biasing body is disposed between said first and second portions of said suture;
wherein said driver is configured to rotate while engaged against said first end region to reduce a length of said suture between said driver and said anchor and generate a biasing force urging said implant into engagement with said anchor, and wherein said biasing force is substantially not transmitted to said bone.
