Abstract: An apparatus and method for performing a surgery, especially an ACL replacement surgery, where a flexible strand insertion rod co-operates with a U-Guide apparatus to insert a flexible strand into a tunnel formed in a bone portion and to guide a pair of drill points to form a pair of tunnels transversely to the tunnel of the insertion rod. The drill points are guided through the insertion rod and the flexible strand is held over the drill points as the transverse tunnels are formed. The insertion rod is then removed from the tunnels formed in the bone and the flexible strand is held looped over the second drill point. Subsequently, a soft tissue replacement is affixed to one end of the flexible strand and pulled over up to the first drill point with the other end of the flexible strand. The first drill point is then used to pull a cross pin through the transverse tunnel to hold the looped end of the soft tissue replacement in place.

A delivery structure includes a connection portion selectively coupled to the opening of the expandable member. The delivery structure is adapted to inject a flowable medium into the expandable member thereby expanding the expandable portion and urging the soft tissue replacement into a bone surface defining the bone tunnel.

Abstract: A system for replacing a hip joint can include a first acetabular cup formed of a first material and having a first inner diameter and a first thickness. A second acetabular cup can be formed of a second material and having a second inner diameter and a second thickness. A first femoral hip prosthesis can include a first femoral head that is alternately accommodated by either of the first or second acetabular cups. A bearing can be adapted to be interposed between the first femoral head and one of the first or second acetabular cups. The first and second inner diameters can be the same. The first thickness can be less than the second thickness. The first material can be distinct from the second material.

Abstract: An apparatus and method is disclosed for performing a surgery, such as an orthopedic surgery. The apparatus can include a guide portion and an alignment portion. The guide portion can assist in positioning the alignment portion to assist in aligning an implant. The implant can be aligned and positioned to hold a graft relative to a bone portion.

Abstract: A resorbable suture anchor operable to hold a suture within a bone. The suture anchor has a cannulated tip that receives a driver during implantation of the anchor, the driver extending from the tip when the anchor is seated on the driver. The anchor further has at least one engagement surface to prevent migration of the anchor from the implantation site. The anchor is made of a resorbable material to permit resorbtion of the anchor within a patient at a desired rate.

Abstract: A suture construction and method for forming a suture construction is disclosed. The construction utilizes a suture having an enlarged central body portion defining a longitudinal passage. First and second ends of the suture are passed through first and second apertures associated with the longitudinal passage to form a pair of loops. Portions of the suture lay parallel to each other within the suture. Application of tension onto the suture construction causes constriction of the longitudinal passage, thus preventing relative motions of the captured portions of the suture.

Abstract: A prosthesis to replace a portion of the anatomy, such as the acetabulum, can include a first portion. A second prosthesis portion can be positioned relative to the shell to provide the bearing surface to articulate with a femoral head prosthesis or femoral head.
