Methods and apparatuses including apparatuses that can be used in a unicompartmental knee replacement procedure, a bicompartmental knee replacement procedure comprised of two unicompartmental knee replacements, a knee replacement procedure that utilizes a single femoral component and two unicompartmental tibial components, and other types of knee replacement procedures are disclosed. According to one example, an apparatus for guiding a tibial bone cut during knee replacement surgery is disclosed. The apparatus can comprise a mounting portion and a cutting portion. The mounting portion can be configured to couple with an alignment mechanism. The cutting portion can be connected to the mounting portion and can define a capture for a proximal cut. The cutting portion can have an aperture disposed adjacent a first end of the capture.

Tibial cut guide

Methods and apparatuses including apparatuses that can be used for guiding resection of a tibia during a knee replacement surgery procedures are disclosed. According to one example, an apparatus for guiding a tibial bone cut during knee replacement surgery is disclosed. The apparatus can comprise a first portion and a second portion. The first portion can be configured to position the apparatus relative to one or more of a medial condyle of a femur, a lateral condyle of the femur, a medial condyle of a femoral component and a lateral condyle of the femoral component. The second portion can be connected to the first portion and can define one or more slots. The slots can be configured for at least one of a first proximal cut and a first sagittal cut to the tibia.

An orthopedic device holder and related kit are disclosed. The orthopedic device holder can include a body portion having a proximal end and a distal end, the body portion defining a bore positioned between the proximal end and the distal end, a plunger portion having a proximal end and a distal end, the plunger portion extending into an opening of the body portion and defining a second bore, and a locking lever that, when activated, is configured to move between a first position and a second position and transition the first bore and the second bore from a locked configuration to an unlocked configuration.

Orthopedic device holder

A system that can be used in a knee replacement procedure can include a tibial cut guide and an alignment guide. The tibial cut guide can have a first guide portion coupled to and adjustable relative to a second guide portion. The first guide portion can be configured to define a sagittal cut slot and a proximal cut slot. The alignment guide configured for extramedullary mounting to the patient and configured to couple with the second guide portion of the tibial cut guide, the alignment guide having a first mechanism and a second mechanism of differing construction, the first mechanism and the second mechanism are both configured to be actuated to facilitate extension and retraction of the alignment guide to position the tibial cut guide in a desired proximal-distal location relative a tibia of a patient when the tibial cut guide and the alignment guide are assembled together.

Assembly and system including a tibial cut guide

Apparatuses and systems including an instrument for manipulating components within a knee joint of a patient are disclosed. Such manipulation can include inserting and/or removing such components to or from a bone of the knee joint. The instrument can include a handle, a body, a plunger, a detent and a collar. The handle can have a proximal end and a distal end and a longitudinal extent between the proximal end and the distal end. The body can be coupled to the handle and can extend distal of the distal end. The body can define a receptacle therein having an opening at a distal end portion of the instrument. The plunger can be moveably disposed within the body and can be moveable between a first position and a second position. The detent can be moveable by the plunger, such that with the plunger in the first position at least a portion of the detent can extend into the receptacle and with the plunger in the second position the detent can be recessed from the receptacle. The collar can be disposed about at least a portion of the body and can be moveable relative to the body to operatively actuate the plunger from the first position to the second position.

Multi-use tool

A keyboard is configured for inputting letters of an alphabet into a computing device. The keyboard has a left-side keyboard section and a right-side keyboard section. The left-side keyboard section comprises a left-side cluster of letter keys formed from letter keys in multiple different left-side rows, including a left-side top row and a left-side bottom row that each has only a single letter key. Letter keys forming a perimeter of the left-side cluster are arranged around the perimeter in alphabetical order according to said alphabet. Similarly, the right-side keyboard section comprises a right-side cluster of letter keys formed from letter keys in multiple different right-side rows, including a right-side top row and a right-side bottom row that each has only a single letter key. Letter keys forming a perimeter of the right-side cluster are arranged around the perimeter in alphabetical order according to said alphabet.

Non-qwerty keyboard

Apparatuses and systems including at least one of mounting and removal of a femoral component on a femur are disclosed. The instrument can include a handle, a plunger, first and second arms and a knob. The handle can define a recess. The recess can extend along a portion of an elongate length of the handle. The plunger can be moveably disposed within the recess and can be configured to extend through an opening in a distal end of the handle to engage a pad to contact the pad against the femoral component. The first and second arms can be pivotally coupled to the handle and can be pivotable relative to one another. The first and second arms can each have at least one coupling feature configured to engage with a corresponding second coupling feature in the femoral component. The knob can be configured to operatively actuate the plunger to move the plunger proximal/distal within the recess to engage the plunger with and disengage the plunger from the pad. The instrument can reduce surgical time by providing a secure grasping and manipulation of the femoral component.

Femoral inserter and retractor

Methods and apparatuses including an apparatus for guiding a femoral bone cut during knee replacement surgery are disclosed. The apparatus can comprise a cut guide having a first side, a second side, a third side, and one or more slots. The first side can be configured to interface with a resected surface of a femur. The second side can be spaced from the first side. The one or more slots can be defined by the apparatus and extend from the first side to the second side. The third side can be disposed between the first side and the second side and can have at least one projection extending therefrom. The at least one projection can be configured to guide a cutting tool into the one or more slots.

Femoral finishing guide

Methods and systems for determining a patient specific soft tissue location within a joint are discussed. For example, a method can include imaging a target location for an orthopedic implant to collect image data regarding a morphology of the patient, the morphology including at least one of bone size and bone feature. The method can additionally include accessing stored soft tissue data and bone data corresponding to the target location of the orthopedic implant, locating a soft tissue of the patient based at least in part upon the soft tissue data and bone data and the image data, and displaying data including the location of the soft tissue of the patient. This data can be used to created patient specific surgical jigs according to one example of the present application.
