An instrumentation set for preparing a proximal tibia during a bi-cruciate retaining procedure can include a tibial resection block and a stylus. 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 stylus can have a first block attachment feature and a second block attachment feature. The first block attachment feature can be offset from the stylus a first distance. The second block attachment feature can be offset from the stylus a second distance. The first and second block attachment features of the stylus can be selectively and alternatively received by the slot of the tibial resection block to position the stylus at distinct offset locations relative to the slot.

Bi-cruciate knee system

A method of preparing a knee joint for a prosthesis in a patient includes mating a patient-specific three-dimensional curved inner surface of a femoral alignment guide onto a corresponding three-dimensional femoral joint surface of the patient. The patient-specific three-dimensional curved inner surface is preoperatively configured from medical scans of the knee joint of the patient. First and second holes are drilled into an anterior portion of the femoral joint surface through corresponding first and second guiding apertures of the femoral alignment guide.

Patient-specific knee alignment guide and associated method

An orthopedic implant manufacturing method. The method includes preparing a pre-operative surgical plan for a specific patient, the surgical plan including a three-dimensional image of a patient's joint indicating at least one resection plane, communicating the surgical plan to a surgeon of the patient, and receiving approval of the surgical plan and the resection plane by the surgeon. The method also includes providing automated osteophyte/protrusion removal control for surgeon manipulation, receiving a modified three-dimensional image of a patient's joint indicating an osteophyte/protrusion removal and a recommendation for a corresponding selected orthopedic implant from the surgeon, and requesting manufacture of the selected orthopedic implant.

Method and apparatus for manufacturing an implant

A method for pre-operative orthopedic planning includes obtaining only a high-resolution knee-joint scan of a patient, determining hip rotation center and ankle rotation center from anthropometric data based on personal data of the patient, and determining a mechanical axis of the knee joint based on the anthropometric data. The method also includes preparing at least a two-dimensional image model of the knee joint using the knee-joint scan and the determined mechanical axis, and preparing a pre-operative surgical plan based on the image of the knee joint.

Patient-specific pre-operative planning

A system for an anatomical joint includes a first fastener, a second fastener, a prosthetic ligament member, and a biasing member associated with at least one of the first and second fasteners. The first fastener is operable to be connected to a first bone portion. The second fastener is operable to be connected to a second bone portion. The prosthetic ligament member is flexible and is directly coupled to both the first and second fasteners to support the first bone portion and the second bone portion for relative movement. A portion of the prosthetic ligament member extends from the first fastener to the second fastener and has an adjustable length. The biasing member is operable to bias the prosthetic ligament member to thereby maintain tension in the prosthetic ligament member.

Prosthetic ligament system for knee joint

A patient-specific guiding system for guiding an instrument relative to a portion of an anatomical feature of a patient. The patient-specific guiding system includes a patient-specific guide. The guide includes a first portion having a first patient-specific inner surface that conforms to a first surface of the anatomical feature and an outer surface opposite the first patient-specific inner surface. The first portion also includes a guide surface for use in guiding the instrument relative to the anatomical feature. The guide also includes a second portion having a second patient-specific inner surface that conforms to a second surface of the anatomical feature and an outer surface opposite the second patient-specific inner surface. The second portion is removably connected to the first portion.

A prosthetic assembly is provided. The prosthetic assembly comprises: a tibial tray having a medial retaining bracket, a lateral retaining bracket and a substantially centrally disposed boss, a medial bearing, a lateral bearing and a retention clip having a pair or arms which engage opposite sides of the boss and trap the medial lateral bearings, against the medial and lateral retaining brackets, respectively. A method of securing bearing components to a prosthetic assembly is also provided.

Anterior locking clip

A method for preparing a backup kit for a plurality of patient-specific arthroplasty procedures scheduled at the same medical facility includes providing a database with data from completed arthroplasty procedures using patient-specific arthroplasty kits. The database includes comparisons between preoperatively planned implant size and intraoperatively implanted implant size. The method includes determining a statistically expected implant size deviation from a planned implant size for each implant included in a plurality of patient-specific arthroplasty kits prepared for a shipment to the medical facility using the database. A backup kit of backup implants is assembled for the shipment. The number and size of the backup implants is determined from the statistically expected implant size deviations.

An orthopedic device for a shoulder joint includes a patient-specific alignment guide. The alignment guide includes a cap having a three-dimensional engagement surface customized in a pre-operative plan by computer imaging to be complementary and closely mate and conform to a humeral head of a proximal humerus of a patient. The alignment guide includes a tubular element extending from the cap and defining a longitudinal guiding bore for guiding an alignment pin at a patient-specific position and orientation determined in the pre-operative plan, and an orientation feature on the cap. The orientation feature is designed to orient the cap relative to the humeral head when the orientation feature is aligned with a landmark of the proximal humerus.

Patient-specific shoulder guide

An orthopedic device includes a femoral implant having a non-custom internal bone engagement surface. The femoral implant includes at least nine parameters adjusted preoperatively to correspond to a specific patient. The parameters can include patient-specific lengths, such as, for example, medial and lateral condyle widths and notch height, and patient-specific medial and lateral angles.

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. The method further includes preparing a surgeon instrument kit containing the set of surgical instruments in sterilized form.

Backup surgical instrument system and method

A patient-specific augment can be attached to an implant component for a bone of a joint of a patient. The patient-specific augment has first and second surfaces. The first surface is a three-dimensional patient-specific surface that closely matches and can mate to a substantially unaltered and unresected surface of a bone defect of the specific patient only in one position. The second surface is designed to engage a non-custom surface of the implant.

Patient-specific augments

A cut block positioning jig including a first alignment member, a second alignment member, and both first and second guide members. The first alignment member is movable towards and away from a patient's bone to which the positioning jig is mounted to arrange the jig at a predetermined position relative to the bone based on x-rays of the patient. The second alignment member is movable towards and away from the bone to arrange the jig at the predetermined position relative to the bone. The first and second guide members are configured to direct cut block support members to the bone to couple a cut block to the bone to provide the bone with patient-specific cuts.
