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 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: 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.

Abstract: Disclosed herein are patellar implants and methods to prepare bone for receiving the same. The patellar implant may include an articulating surface and an anterior surface with a non-planar surface to engage with a resected patella. The non-planar surface may include a conically shaped portion to receive the resected patellar bone. A method for resurfacing a patella to implant a patellar implant having a recessed anterior surface may include the steps of determining the minimum implant and resection depth, medial and lateral patellar slope angles to select and resect with a symmetrical reamer.
