Abstract: Disclosed herein are an implant with an attachment feature and a method for attaching to the same. The implant may include a cavity with a porous layer disposed within a non-porous layer wherein the non-porous layer defines a chamber. The chamber may receive and confine liquefiable material and direct liquefiable material to permeate through the porous layer. A method of attaching a device to the implant may include liquefying a liquefiable portion of the device and allowing the liquefied material to interdigitate with the second layer and then solidify to prevent pullout.

Abstract: A method of generating a correction plan for a knee of a patient includes obtaining a ratio of reference bone density to reference ligament tension in a reference population. A bone of the knee of the patient may be imaged. From the image of the bone, a first dataset may be determined including at least one site of ligament attachment and existing dwell points of a medial femoral condyle and lateral femoral condyle of the patient on a tibia of the patient. Desired positions of contact in three dimensions of the femoral condyles of the patient with the tibia of the patient may be obtained by determining a relationship in which a ratio of bone density to ligament tension of the patient is substantially equal to the ratio of reference bone density to reference ligament tension.

Abstract: In some embodiments, the present disclosure relates to a method of securing an implant into a body of a patient. Initially, the implant is placed into the body of the patient. Then, an impactor tool is used to apply a force to the implant. Subsequent to the application of force to the implant, a portion of an impaction pad on an end of the impactor tool is monitored. When the portion is observed to be deformed, the application of force onto the implant is discontinued.

Abstract: A system for converting a first joint prosthesis to a second joint prosthesis in-situ includes a plurality of inserts having a bone interface side and a component facing side and a plurality of articulating components having a cavity configured to receive at least one of the plurality of inserts. The plurality of inserts may be unicompartmental, bicompartmental, or tricompartmental. The inserts may be made of metal and may have a bone contacting surface made of a porous metal. The plurality of articulating components may be unicompartmental, bicompartmental, or tricompartmental. The articulating components may be sized and shaped to cover one or more of the plurality of bone interface components and span a distance therebetween. The articulating components may be made of a polymer.

Abstract: A method of determining a boundary of a cancer of a bone of a patient includes imaging the patient's bone. A bone density ratio of interest may be obtained from the image of the bone, the bone density ratio of interest being a ratio of a first density of the bone at a first location in the image to a second density of the bone at a second location in the image. The obtained bone density ratio of interest may be compared to a reference bone density ratio of interest of a reference bone without bone cancer. Based on the comparison, it may be determined whether the cancer of the bone of the patient is present at the first location in the image or the second location in the image. The imaging may be CT imaging, and the imaging may include a first plurality of images in a first plane.
