Instruments and components for improving the accuracy of resection of the proximal tibia in a kinematic alignment total knee arthroplasty ('TKA'). Instruments include an adjustable double tibial stylus instrument comprising: a first wide convex stylus tip and a second wide convex stylus tip at a second distal end of the second stylus. The wide convex stylus tips may be fixed components of the adjustable double stylus instrument, or the wide convex stylus tips may be detachable.

Tibial dual stylus instrument having wide convex stylus tips and components thereof

Systems and methods for ascertaining a position of an orthopedic element in space comprising: capturing a first and second images of an orthopedic element in different reference frames using a radiographic imaging technique, detecting spatial data defining anatomical landmarks on or in the orthopedic element using a deep learning network, applying a mask to the orthopedic element defined by an anatomical landmark, projecting the spatial data from the first image and the second image to define volume data, applying the deep learning network to the volume data to generate a reconstructed three-dimensional model of the orthopedic element; and mapping the three-dimensional model of the orthopedic element to the spatial data to determine the position of the three-dimensional model of the orthopedic element in three-dimensional space.

Systems and methods of using photogrammetry for intraoperatively aligning surgical elements

Systems and methods for generating patient-specific surgical guides comprising: capturing a first and second images of an orthopedic element in different reference frames using a radiographic imaging technique, detecting spatial data defining anatomical landmarks on or in the orthopedic element using a neural network, applying a mask to the orthopedic element defined by an anatomical landmark, projecting the spatial data from the first image and the second image to define volume data, applying the neural network to the volume data to generate a reconstructed three-dimensional ('3D') model of the orthopedic element; and calculating dimensions for a patient-specific surgical guide configured to abut the orthopedic element.

Systems and methods for using photogrammetry to create patient-specific guides for orthopedic surgery

Systems and methods for calculating external bone loss for alignment of pre-diseased joints comprising: generating a three-dimensional ('3D') computer model of an operative area from at least two two-dimensional (“2D”) radiographic images, wherein at least a first radiographic image is captured at a first position, and wherein at least a second radiographic image is captured at a second position, and wherein the first position is different than the second position; identifying an area of bone loss on the 3D computer model; and applying a surface adjustment algorithm to calculate an external missing bone surface fitting the area of bone loss.

Systems and methods of using three-dimensional image reconstruction to aid in assessing bone or soft tissue aberrations for orthopedic surgery

Systems, methods, kits, and devices for transferring kinematic alignment references from the distal aspect of a femur to the proximal aspect of an adjacent tibia. An exemplary assembly includes a distally referencing linking drill guide assembly comprising: a linking drill guide comprising: a femoral portion, the femoral portion configured to engage a first femoral engagement member, a tibial portion, the tibial portion configured to engage a first tibial engagement member, and a body connecting the femoral portion to the tibial portion, and a femoral referencing instrument, the femoral referencing instrument having a first complimentary femoral engagement member, wherein the assembly has an engaged configuration when the first femoral engagement member engages the first complimentary femoral engagement member, and wherein the assembly has a disengaged configuration when the first femoral engagement member does not engage the first complementary femoral engagement member.

Tibial guide transfer instruments and methods

An instrument for setting a position of a resection of a distal femur or a proximal tibia in a total knee arthroplasty, the instrument comprising: a stable portion, the stable portion configured for orientation in a set position relative to said distal femur or said proximal tibia; a resection guide portion, the resection guide portion configured to guide a resection path for said resection; a resection guide body, the resection guide body associated with the resection guide portion in a fixed orientation; the resection guide body pivotally connected to the stable portion, whereby pivoting adjustment of the resection guide body on the stable portion sets a resection orientation of the resection guide portion; and the resection guide body having a lock for selectively locking the resection guide body to the stable portion at a plurality of selectable resection orientations.

Dual stylus variable angle total knee instruments and methods

A device for preparing a femur of a patient for receipt of a knee implant in both extension and flexion relative to a resected tibia plateau based on applying tension to medial and lateral collateral ligaments of said patient, comprising a tibial baseplate, a tensioner, the tensioner comprising a tensioner body having a tensioner portion, the tensioner portion affixed to the tibial baseplate, and an expander arm comprising an elongated body portion, a superior side of the elongated body portion having a spiked tip adjacent a posterior end thereof. The spiked tip interacts with an intracondylar notch under tension. The expander arm is operatively connected to the tensioner body via the tensioner portion, the tensioner portion configured for use in selectively raising and lowering the expander arm relative to the tibial baseplate to apply tension to the medial and lateral collateral ligaments in extension or flexion.

Soft tissue tension guided bone resection instruments and methods

An ankle prosthesis has a tibial component configured for attachment to a tibia of a person, and a talar component. The talar component has a first surface configured for facing the tibial component and a second surface configured for facing a talus of the person. The second surface has first and second arms attached to it, for pivoting or flexing outwardly in medial and lateral directions, respectively, to engage side surfaces of a previously formed slot in the talus.

Soft tissue tension and bone resection instruments and methods

A sizing caliper for facilitating the selection of a femoral component of a knee prosthesis includes a caliper body, two drill guide bodies, a stylus tower configured to be slidably linked to each other wherein as the caliper body and the stylus tower are linearly displaced at an equal rate relative to the drill guide body portions and the drill guide holes remain located at the midpoint of an anterior/posterior dimension defined by the distance between the tip of the stylus and the base portion. The caliper body comprises a base portion configured to couple and decouple from the caliper body using a sliding mechanism.

Midline referencing femoral sizing caliper

A surgical instrument for making femoral resections for seating a femoral implant on a distal femur, the instrument configured for orientation relative to an intramedullary rod. The instrument includes a medial distal cut guide having a cut guide portion, the cut guide portion having a cut slot therein for use in resecting a medial distal condyle of the femur. A medial distal cut paddle supports the medial distal cut guide. The medial distal cut paddle is configured to mount on the intramedullary rod to orient the medial distal cut slot substantially along an anterior-medial slope of the medial distal condyle when the medial distal cut paddle is mounted on the intramedullary rod to thereby define an anterior-medial approach for making a medial distal resection of the medial distal condyle.

Instruments for minimally invasive surgery total knee arthroplasty

A patellar clamp and associated system and method for using the clamp are provided. A patellar clamp includes a pair of handles movably coupled together, a patella support portion connected to the pair of handles and configured to engage a first side of a patella, and a reamer guide configured to engage a second side of the patella. The patella support portion and the reamer guide each include a first pair of flanges configured to engage a first and second tendon associated with the patella. The reamer guide is configured to allow reaming and resurfacing the entire desired posterior articular surface of the patella in a single operation without readjusting the position of the reamer guide.
