Abstract: A system for monitoring a patient includes a sensor unit having a housing and sensors disposed in or around the housing; and a base having a shell and configured and arranged to be adhesively attached to skin of the patient. The sensors can be used to monitor physical therapy and rehabilitation of the patient. The sensor unit can provide information to a patient or clinician device to facilitate the monitoring. In some instances, the sensor unit and base are magnetically coupled together. In some instances, the base has an opening so a temperature sensor of the sensor unit can be exposed to the skin of the patient.

Abstract: A system for monitoring a joint of a patient includes multiple sensors to be disposed near a joint and to measure or observe actions or physical quantities associated with the joint; and at least one communications module coupled to the sensors to receive data from the sensors and to transmit sensor information to an external device. In some embodiments, the sensors are implantable near the joint. In other embodiments, the sensors are disposed in a sensor module that is positioned adjacent the skin of the patient near the joint.

Abstract: A system for monitoring a patient includes a sensor unit having a housing and sensors disposed in or around the housing; and a base having a shell and configured and arranged to be adhesively attached to skin of the patient. The sensors can be used to monitor physical therapy and rehabilitation of the patient. The sensor unit can provide information to a patient or clinician device to facilitate the monitoring. The sensor data can be used to determine measurements such as tilt angle of the sensor unit and range of motion measurements (such as extension, flexion, or forces associated with movement) of the anatomical region to which the sensor unit is attached. The sensor data can also be used for automated identification or classification of exercises performed by the patient.

Abstract: An orthopedic joint prosthesis may include a first component, a bearing component, and a third component. The first component has a base and a keel protruding from the base to extend into a first bone. The keel's longitudinal axis is offset from a geometric center of the base. The base has a first articular surface and the bearing component has a second articular surface shaped to articulate with the first articular surface. A feature unitary with the first component reversibly attaches to the bearing component. The bearing component has a third articular surface shaped to articulate with a fourth articular surface on the third component. A distraction feature of the bearing component is shaped to provide alignment and/or distraction between the first articular surface and the fourth articular surface during insertion of the bearing component into a joint space between the first and second bones.

Abstract: A prosthetic tibial component for a knee joint, said prosthetic tibial component comprising: a base construct for engaging the tibia; and a bearing construct for engaging the femoral side of the knee joint; said bearing construct being adjustably fixedly mountable to said base construct.

Abstract: An improved body element for use in a modular prosthetic stem component of the sort comprising a body element and at least one other element, wherein the body element and the at least one other element are joined together by at least one modular connection, wherein the improved body element comprises an anterior wall and a posterior wall, at least one of the anterior wall and the posterior wall converging toward the other on the medial side of the body element and diverging away from the other on the lateral side of the body element, whereby the body element approximates a general wedge shape.

Abstract: Systems and methods are described for implants with composite coatings to promote tissue in-growth and/or on-growth. An implant includes: a substrate; a structured surface formed on at least a portion of the substrate; and a biocompatible coating deposited on at least a fraction of the structured surface. The systems and methods provide advantages in that the implant has good biocompatibility while the biocompatible coating has good strength.
