A method for removing a stem portion of an orthopedic implant from a bone comprises exposing an implanted orthopedic implant having a body portion, a stem portion interconnected to the body and a porous metal section forming an interconnection between the body and the stem portion. A cutting tool is mounted on a holder connected to an exposed surface of the orthopedic implant. The porous section is aligned with the cutting tool mounted on the holder. The entire porous section is cut by moving the cutting tool therethrough in a direction transverse to the stem portion axis. The implant body portion is then removed and then the stem portion is removed from the bone. The cutting tool may be a saw or chisel which may be mounted on a guide fixed to the body portion.

An orthopaedic surgical instrument system includes a compression socket configured for coupling with a selected one of a number of compressible bases. Each compressible base is shaped to conform with a posterior surface of either a dome patella implant component or an anatomical patella implant component.

Methods and devices for correcting wear pattern defects in joints. The methods and devices described herein allow for the restoration of correcting abnormal biomechanical loading conditions in a joint brought on by wear pattern defects, and also can, in embodiments, permit correction of proper kinematic movement.

A femoral implant for articulation with a patella or a patellar implant includes a body having an articular surface defining a trochlear groove. The trochlear groove is defined by a first trochlear radius at a first location along the trochlear groove and by a second trochlear radius at a second location along the trochlear groove, the first radius being different than the second radius. The configuration of the trochlear groove is such that it narrows as a patella or patellar implant moves from an extension configuration to a flexion configuration. A kit includes the femoral implant along with a patellar implant. A method of trialing involves use of the femoral implant or kit to ensure a smooth transition of the patella or the patellar implant from the femoral component to the adjacent bone.

Disclosed herein are systems and methods for providing secure authentication and connection between an implant and a remote monitoring platform for tracking implant performance. A joint implant according to the present disclosure can include a first implant coupled to a first bone of a joint, a second implant coupled to a second bone of the joint, a first communication module, and a memory to store authentication information. The first communication module can be configured to wirelessly transfer the authentication information to a communication module of an external device when the external device is placed adjacent the joint implant. The first communication module can be an NFC communication module configured to transfer the authentication information to the communication module of the external device via NFC.

Disclosed herein are joint implants and methods for tracking joint implant performance. A joint implant includes a first implant coupled to a first bone of a joint and a second implant coupled to a second bone of the joint. The second implant includes at least one of a first sensor configured to measure a first type of data, and a processor operatively coupled to the at least one of the first sensor. The process outputs the first type of data to a network to be compared with data received from other joint implants. One of the joint or the implant is determined to be in a first state based on a comparison of the first type of data to a set of predetermined values formed based on the data received from the other joint implants. The predetermined values are adapted to change with the addition of new data.

Disclosed herein is a joint implant including a first implant coupled to a first bone of a joint, and a second implant coupled to a second bone of the joint and contacting the first implant. The second implant can include a plurality of sensors configured to measure data and a processor operatively coupled to the plurality of sensors and adapted to receive the data from the sensors. The processor can be configured to communicate with a neural network and a channel detector adapted to exclude a first portion of the data received from the processor and output a second portion of the data.

Disclosed herein is a joint replacement system and a method of performing surgery. The joint replacement system may include a first implant having a marker, a second implant having a reader to detect the marker, and a processor in communication with the second implant. The processor may include different algorithms based on the first and second implants. The method may comprise the steps of receiving first information related to a first implant, receiving second information related to a second implant, selecting an algorithm based on the first and second information; and receiving data from the first and second implants utilizing the algorithm.

Disclosed herein are joint implants with sensors and methods for manufacturing joint implants with sensors. A knee joint implant according to the present disclosure may include a femoral implant, a tibial implant and a tibial insert disposed therebetween. The tibial implant may include a medial side with a medial central region defined around a medial center, a lateral side with a lateral central region defined around a lateral center and a central region disposed between the medial central region and the lateral central region. At least one sensor and a battery may be disposed within the tibial insert. The medial central region and the lateral central region may be defined by solid volumes extending from a proximal surface to a distal surface of the tibial insert.

Disclosed herein are implants with sensors and methods for powering implants with sensors. A joint implant according to the present disclosure can include a first implant and a second implant in contact with the first implant. The first implant can be coupled to a first bone of a joint. The first implant can include an energy generator coupled to a transducer. The second implant can include at least one sensor, a battery coupled to the at least one sensor, and a receiver coupled to the battery. The receiver can be disposed within the second implant adjacent the transducer. Energy from the energy generator can be transmitted from the transducer of the first implant to the receiver of the second implant.
