  • Patent number: 10485555
    Abstract: An instrument set and related method for preparing a proximal tibia during a bi-cruciate retaining procedure are disclosed. The instrument set can include a tibial resection block, a cut guide, and a locking arm. The tibial resection block can be configured to be fixed to an anterior portion of the proximal tibia. The tibial resection block can define a slot that extends in a medial-lateral direction when the tibial resection block is fixed to the proximal tibia. The cut guide can have a body, a medial arm, and a lateral arm. A medial cut slot can be defined between the body and the medial arm. A lateral cut slot can be defined between the body and the lateral arm. The cut guide can further comprise a tongue extending therefrom. The tongue can be configured to be received by and slidably translate along the slot of the tibial resection block.

  • Publication number: 20180358120
    Abstract: A method can include receiving, at a server, preoperative image data of a patient's bone, and accessing, at the server, a database of three-dimensional model data. A patient specific three-dimensional model of the patient's bone can be generated, at the server. A preoperative surgical plan can be generated at the server, which can include comparing aspects of the preoperative surgical plan with predetermined reliability criteria. An interactive user interface for use by a surgeon to review the preoperative surgical plan can be provided, from the server, to a user device. Approval of the preoperative surgical plan can be received, at the server, via the interactive user interface. Postoperative image data of the patient's bone can be received at the server. A postoperative outcome study report can be generated, at the server, and can include a comparison of the preoperative surgical plan with the postoperative image data.

  • Publication number: 20180168690
    Abstract: A method for preparing surgical kits for use during a surgery includes preparing a pre-operative surgical plan for a patient and selecting a set of surgical instruments based on the pre-operative surgical plan. The set of surgical instruments includes at least a general instrument, a first size-specific instrument, a patient-specific instrument, and a surgeon-specific instrument. The general instrument is selected from a predetermined group of off-the-shelf instruments. The first size-specific instrument has a first size selected from predetermined sizes. The patient-specific instrument includes a three-dimensional contoured engagement surface configured to nest into a portion of a native anatomy in a single location. The surgeon-specific instrument is selected based on a surgeon preference and is a different instrument than the selected general instrument, first size-specific instrument, and patient-specific instrument.

  • Patent number: 9931218
    Abstract: A method of implanting a prosthesis based on bone density of a bone is provided. A first bone density of the bone may be determined at a first portion of the bone. A second bone density of the bone may be determined at a second portion of the bone. A first desired amount of bone removal may be determined at the first portion of the bone based on the first bone density.

  • Publication number: 20170319219
    Abstract: An orthopedic device includes a drill guide configured to be mounted on a patient-specific alignment guide for intraoperatively confirming alignment of the patient-specific alignment guide relative to a bone. The patient-specific alignment guide includes first and second referencing holes. The drill guide includes a main body with a first coupling member and a second coupling member. The first and second coupling members are configured to be received within the first and second referencing holes, respectively. The first and second coupling members each include corresponding first and second drill openings configured to align with the first and second referencing holes, respectively. The drill openings each guide a drilling tool toward the bone to drill corresponding holes in the bone. The main body also includes an alignment confirmation feature configured for confirming alignment of the patient-specific alignment guide relative to the bone before drilling holes in the bone.

  • Patent number: 9579112
    Abstract: A patient-specific tibial pin guide for placement on a tibia during a joint arthroplasty procedure on a patient is disclosed. The tibial pin guide includes a patient-specific inner surface having a first offset portion and a second offset portion. The first offset portion is configured to be offset from and mimic a first bone surface. The first offset portion of the patient-specific inner surface is shaped to form a gap to accommodate soft tissue overlying a proximal surface of the tibia of the patient. The second offset portion of the patient-specific inner surface is shaped to provide clearance for a patella tendon of the patient. The tibial pin guide also has a first patient-specific contact area configured for direct bone registration without intervening soft tissue and a second patient-specific contact area that is configured for direct bone registration without intervening soft tissue. The second patient-specific contact area is non-contiguous with the first patient-specific contact area.

  • Patent number: 9474539
    Abstract: A method of intraoperatively selecting between a partial knee arthroplasty and total knee arthroplasty includes mounting a patient-specific three-dimensional surface of a convertible patient-specific guide in a unique position mating to a corresponding surface of a distal femoral bone. The convertible patient-specific guide includes an anterior portion and a distal portion a patellofemoral guide. One of a total knee arthroplasty and a partial knee arthroplasty is selected intraoperatively. If total knee arthroplasty is selected, first and second covers are removed from corresponding first and second distal guiding bore. First and second distal pins through the first and second distal guiding bores are registered on the bone. If partial knee arthroplasty is selected, the anterior portion is severed and removed along a frangible groove and the distal portion is used as a patellofemoral guide.
