Embodiment Construction

[0044] The presently preferred embodiments are shown in the drawings. Although this description is primarily concerned with knee replacements, it should be understood that the subject matter described here is applicable to other joints in the body, such as, for example, the shoulder, elbow, wrist, spine, hip or ankle, as well as any other orthopedic and / or musculoskeletal implants, including implants of traditional materials as well as more specialized implants such as bone biomaterials, drug delivery implants, and cell delivery implants.

[0045] In an overview, multi-component implant planning is achieved by constraining the adjustment of the individual components of the multi-component implant. Each component is adjustable based on constraints, allowing proper fit of each implant component while preventing improper placement. figure 1 An exemplary multi-component implant planning system 100 according to the present invention is shown. The system includes a computer 102 . ...

Abstract

Described are computer-based methods and apparatuses, including computer program products, for implant planning using areas representing cartilage. A predetermined number of control points for generating a predetermined number of areas representing cartilage are determined, wherein the predetermined number of control points are based on an implant component. Measurements corresponding to a plurality of measured cartilage points are received, wherein each cartilage point is based on an associated control point from the predetermined number of control points. A plurality of areas representing cartilage are generated, wherein each area representing cartilage is larger than and projects to an associated control point from the plurality of control points. A representation of the implant component is positioned based on a representation of a bone, the representation of the bone comprising representations of the plurality of areas representing cartilage.

Description

technical field [0001] The present invention relates generally to surgical computer systems, including computer program products and methods of implant planning using regions representing cartilage, and more particularly to estimating regions representing cartilage. Background technique [0002] Orthopedic joint replacements may include arthroplasty of the knee, hip, or other joints (eg, shoulder, elbow, wrist, condyles, fingers, etc.). For example, traditional total knee arthroplasty (TKA) involves a long incision, usually in the range of about 6 to 12 inches, to expose the joint for bone preparation and implantation of implant components. The invasive nature of cutting results in prolonged recovery times for patients. Minimally invasive surgery (MIS) reduces the length of the incision for total knee replacement surgery to a range of approximately 4 to 6 inches. However, smaller incision sizes impair the surgeon's ability to visualize and capture joint anatomy. As a resu...
