  • Patent number: 9693786
    Abstract: A method for repairing a soft tissue or bone defect can include selecting one of a plurality of sizing guides having a base perimeter size corresponding to a size of the defect, where each base has a different perimeter size and a plurality of apertures spaced apart a predetermined distance from each other, with the predetermined distance being the same for each of the sizing guides. The selected sizing guide base can be positioned against a distal end of the femur relative to the defect. A plurality of guide wires can be positioned through the plurality of apertures in the sizing guide base and the guide wires can be fixed to the femur such that the guide wires are parallel to each other. A first guide can be positioned over the guide wires and against the distal end of the femur to guide a first cutting member relative to the femur.

  • Patent number: 9456833
    Abstract: An osteotomy method includes attaching a patient-specific osteotomy guide to a corresponding surface of a tibia of a patient and making an osteotomy at a patient-specific orientation through a resection slot of the osteotomy guide. The osteotomy guide is removed and first and second faces of the osteotomy are opened to form an implant insertion angle. The first and second faces of the osteotomy are secured at the implant insertion angle and an osteotomy implant having a patient-specific wedge angle that is smaller than the implant insertion angle is implanted. The first and second faces of the osteotomy are brought to the patient-specific wedge angle and in contact with the osteotomy implant.

  • Publication number: 20160151077
    Abstract: A system can include a sizing and drill guide having a body with a bone engaging side, an opposite side and first and second guide holes. The bone engaging side can include a profile for positioning in the trochlear groove and the guide holes can include axes that can be orientated at an acute angle. Retaining members can be positioned in bores formed in the body and can fix the guide to the femur. A cutting device can be guided by the guide holes and can include a bone engaging end having a body and first and second cutting portions. The first cutting portion can have a smaller diameter than the second cutting portion and can be axially spaced apart therefrom so as to form a stepped pocket in the femur. The body can include an outer diameter sized to be complimentary to an inner diameter of the guide holes.

  • Publication number: 20160100847
    Abstract: A system for repairing a cartilage defect. The system includes a riser block having a bone-engaging side that is a patient-specific negative of a patient's bone anatomy proximate to the cartilage defect. A drill guide-engaging side of the riser block is opposite to the bone-engaging side. A superior riser block guide hole is defined by the riser block and extends from the drill guide-engaging side to the bone-engaging side. An inferior riser block guide hole is defined by the riser block and extends from the drill guide-engaging side to the bone-engaging side.

  • Patent number: 9301766
    Abstract: A system for repairing a soft tissue or bone defect can include a C-shaped guide member having a first end and a second end and configured to extend around a condyle area of a femur of a patient. The guide member includes a threaded bore at the first end, and the second end configured to rest on a tibia of the patient. The system includes a cannulated bullet threadably received in the threaded bore and configured to be threadably advanced to secure the guide member relative to the femur. The system also includes a drilling member insertable through the bullet and configured to drill a femoral bore through the femur.

  • Publication number: 20160089166
    Abstract: Patient-specific guides for a tibial tubercle osteotomy are provided. The guides include a guide body defining a portion with a bone-engaging surface that conforms as a negative surface to a corresponding surface of a specific patient's tibia, and a guide portion that guides a surgical instrument to a specific location on the specific patient's tibia, wherein the bone-engaging surface and guide portion are configured during a pre-operative planning stage. Methods for performing a tibial tubercle osteotomy with the patient-specific guides are also provided.

  • Publication number: 20150342587
    Abstract: An articular capsule retractor including a flexible construct, a dermal abutting member, and an anchor. The flexible construct includes a strand extending between a first end and a second end. The dermal abutting member is coupled to the flexible construct and is configured to abut a dermal layer. The anchor is coupled to the flexible construct such that the strand extends through a passageway defined by the anchor. Pulling the first end and the second end draws the dermal abutting member and the anchor together.

  • Patent number: 9138259
    Abstract: A cutting guide includes a jig assembly that is configured to attach to a second surface of a bone. The jig assembly includes a guide block that defines a jig recess and that is configured to be disposed adjacent to the first surface. Also, the cutting guide includes a tool support that is moveably coupled to the jig assembly, and the tool support is configured to couple to the cutting tool and moveably support the cutting tool on the jig assembly. Moreover, the cutting guide includes an adapter that is removably received within the jig recess to adapt a dimension of the jig recess according to a corresponding dimension of the pocket. The adapter includes at least one adapter surface that is configured to abut the guide portion of the cutting tool to thereby limit movement of the cutting portion relative to the first surface of the bone.
