Abstract

Systems and computer-implemented methods of improving a patello-femoral response. A computing system operably coupled to a markerless navigation system classifies the knee anatomy of the patient into one or more segments, including the patella. The computing system further receives first simulation data of movement of the segmented patella at a first surgical phase, such as a pre-operative phase. The computing system receives second simulation data of the segmented patella at a second surgical phase, such as an intraoperative stage using a first implant type. The computing system generates comparison data based on a comparison of the first and second simulation data. The computing system analyzes the comparison data, along with patient-specific information, via a machine learning model to provide one or more recommendations to improve a patello-femoral response based on reducing, minimizing, or eliminating the differences between the first simulation data and the second simulation data.

A determination is made when the obtained location of the resection equipment is within the defined virtual protection area. The resection equipment is disabled when the determination indicates the obtained location is within the defined virtual protection area. Accordingly, this technology advantageously allows a surgeon to intraoperatively establish a protection area to facilitate automated protection of particular anatomical structures from resection.

Detected sound pressure can be compared to a threshold, which can correspond to background or ambient sound pressure. Background or ambient sound pressure can correspond to sound produced by a negative pressure source. The leak detection device can include a display configured to visually depict the detected sound, and a light source which creates a visual depiction of the coverage angle of the microphone.

Abstract

A system for performing an osteochondral grafting procedure includes one or more processing devices configured to execute instructions to cause the one or more processing devices to obtain first digital data of an anatomical site of a patient, the anatomical site including a recipient site for an osteochondral graft, the recipient site including an osteochondral defect, determine, based on the first digital data, first characteristics of the recipient site, obtain second digital data of a donor site, determine, based on the second digital data, second characteristics of the donor site, and generate, based on the first and second characteristics, a virtual plug corresponding to the osteochondral graft. The virtual plug is configured to conform to the recipient site, and generating the virtual plug includes at least one of storing data defining the virtual plug and providing, on a display, visual guidance based on the virtual plug.

Abstract

A negative pressure wound therapy system can include a reduced pressure wound therapy device and a wound therapy monitoring device configured to emit an indication when it detects that at least one parameter associated with the provision of negative pressure wound therapy is outside an operational range. The wound therapy monitoring device can operate in a low power mode in which the at least one parameter is periodically monitored. The reduced pressure wound therapy device can be configured to detect the indication and selectively generate an alarm. In some cases, the wound therapy monitoring device can be disposed in a wound or in a fluidic connector connecting the reduced pressure wound therapy device to the wound.

Abstract

Systems and methods for patellofemoral preparation are disclosed herein. A method may include receiving patient imagery of a patient's anatomy comprising a knee joint; registering the patient imagery to at least one of a pre-existing anatomical atlas or a three-dimensional model generated from the patient imagery; determining a location of a native femoral trochlear groove of a femur based on the registered patient imagery; determining the location of an implanted femoral trochlear groove from a three-dimensional model comprising a planned modification of the registered patient imagery and an affixed implant comprising femoral implant component; comparing native groove and the implant groove to assess congruence between the patient's anatomy and the implant; and generating a recommendation to modify at least one of a placement of a patella of the knee joint, a surface of the patella, and an attribute of the femoral implant component based on the comparison.
