An apparatus includes first and second fixation members, a flexible member coupled to the first and second fixation members, and a limiting element coupled to the flexible member. The limiting element is movable relative to the second fixation member and acts to limit loosening of the flexible member relative to the second fixation member. The limiting element can be slidably received by the flexible member. The flexible member can be coupled to the fixation members such that pulling on a free end of the flexible member shortens a length of the flexible member between the fixation members.

Apparatus for tissue repair

A method of closing a tissue wound includes providing a wound closure device having a first fastener, a second fastener, and a flexible member extending between the first and second fasteners and movably attached to the second fastener by a one-way knot formed in the flexible member between the first and second fastener, positioning the first fastener against tissue, passing the flexible member across the wound, positioning the second fastener against tissue, and pulling on a free end of the flexible member to shorten a length of the flexible member between the first and second fasteners, thereby closing the wound.

Methods for tissue repair

A patellar 3-D guidance tool includes a template. The template includes at least one contact surface for engaging a surface of the patella. The at least one contact surface substantially conforms with the surface associated with the patellar. At least one guide aperture directs movement of a surgical instrument, wherein the shape and/or position of the guide aperture is based, at least in part, on three or more anatomic reference points associated with the patellar.

Surgical tools for arthroplasty

Disclosed herein are methods, compositions and tools for repairing, replacing or otherwise treating bone ligaments using devices designed from patient-specific information, including without limitation, surgical alignment instruments that have a surface that conforms to at least a portion of a patient's bone, cartilage or other component of the joint or ligament being treated.

Patient-specific joint arthroplasty devices for ligament repair

Methods and devices are disclosed relating improved articular models, implant components, and related guide tools and procedures. In addition, methods and devices are disclosed relating articular models, implant components, and/or related guide tools and procedures that include one or more features derived from patient-data, for example, images of the patient's joint. The data can be used to create a model for analyzing a patient's joint and to devise and evaluate a course of corrective action. The data also can be used to create patient-adapted implant components and related tools and procedures.

Patient-adapted and improved articular implants, designs and related guide tools

Disclosed herein are methods, compositions and tools for repairing articular surfaces repair materials and for repairing an articular surface. The articular surface repairs are customizable or highly selectable by patient and geared toward providing optimal fit and function. The surgical tools are designed to be customizable or highly selectable by patient to increase the speed, accuracy and simplicity of performing total or partial arthroplasty.

A surgical assembly includes a fastener, a retainer, and a flexible member. The fastener is configured to be secured within bone tissue. The flexible member connects the fastener to the retainer and is movably attached to the retainer such that pulling on a free end of the flexible member shortens a length of the flexible member between the fastener and the retainer. A method includes positioning a fastener within bone tissue, positioning a retainer against soft tissue to be attached to the bone tissue, and pulling a free end of a flexible member. The fastener and the retainer are connected by the flexible member, the flexible member is movably attached to the retainer, and pulling on the free end of the flexible member shortens a length of the flexible member between the fastener and the retainer.

Soft tissue attachment and repair

A device includes a body defining a tapered hole for guiding a member, such as a suture thread, into a tube, and a slot communicating with the hole for separating the body and the member. The body defines a bore for receiving the tube. The bore communicates with the tapered hole. The bore has a constant diameter or is tapered. A width of the bore is greater than a width of a narrowest portion of the tapered hole. The slot extends from the tapered hole and the bore to an external surface of the body. A method includes coupling a body to an end of a tube, guiding a member into the tube through a tapered hole, and separating the body and the member by passing the member through a slot.

Suture loading

Methods and devices for tissue repair

Sheaths for implantable fixation devices have a flexible body with a perforated wall, and an interior of the body is sized and shaped to receive the fixation device. Sheaths include a plurality of flexible or inflexible tubes arranged to form a ring, where the central cavity defined by the ring is sized and shaped to receive the fixation device.

Sheaths for implantable fixation devices

A device for securing a graft in a bone tunnel includes an anchoring member having a graft supporting surface. The anchoring member is configured to be positioned within the bone tunnel distal of an interference member with the graft retained by the graft supporting surface and extending proximally from the anchoring member. The anchoring member has an engaging surface for engaging a distal end of the interference member to limit movement of the graft relative to the interference member.
