positioning the first jaw of the suture passer against the hip labrum by adjusting an angle of the first jaw relative to the elongate body;

extending a sharp pointed tip of the second jaw through the hip labrum or between the hip labrum and an acetabulum;

extending and retracting a tissue penetrator from the first jaw or the second jaw of the suture passer, and through the hip labrum between the first and second jaws to pass a suture between the first and second jaws; and

removing the suture passer from the hip labrum while leaving the suture in the hip labrum.

14. A method of minimally invasively suturing a soft tissue in a joint, the method comprising:

inserting a suture passer proximate to the soft tissue, the suture passer including an elongate body, a first jaw bent or bendable relative to the elongate body, and a second jaw that is distally extendable relative to a long axis of the elongate body;

positioning the first jaw of the suture passer against the soft tissue by adjusting an angle of the first jaw relative to the elongate body;

extending a sharp pointed tip of the second jaw through the soft tissue;

extending and retracting a tissue penetrator from the first jaw or the second jaw of the suture passer, and through the soft tissue between the first and second jaws to pass a suture between the first and second jaws; and

removing the suture passer from the soft tissue while leaving the suture in the soft tissue.

15. A suture passer apparatus for passing a suture, the apparatus comprising:

an elongate body extending distally and proximally along a long axis;

a first jaw extending from a distal end region of the elongate body wherein the first jaw is hinged to pivot and form an angle relative to the long axis at a hinge point with the elongate body;

a second jaw having a sharp, tissue penetrating distal tip, wherein the distal end region of the second jaw is curved toward the first jaw and includes an arcuate channel therethrough; and

a tissue penetrator configured to carry a suture, the tissue penetrator configured to extend from the arcuate channel and out of the second jaw towards the first jaw at an angle relative to the long axis.

16. The apparatus of claim 15 wherein the second jaw is configured to extend and retract proximally and distally in the long axis relative to the elongate body.

17. The apparatus of claim 15, wherein the second jaw is configured to retract completely into the elongate body.

18. The apparatus of claim 15, wherein the first jaw is configured to have a neutral position in line with the long axis of the elongate body.

19. The apparatus of claim 15, further comprising a deflection surface on the first jaw configured to deflect the tissue penetrator proximally relative to the first jaw.

20. The apparatus of claim 15, wherein the first jaw is curved.
