Publication number: 20160270696Abstract: Methods are disclosed for assessing the condition of a cartilage in a joint and assessing cartilage loss, particularly in a human knee. The methods include converting an image such as an MRI to a three dimensional map of the cartilage. The cartilage map can be correlated to a movement pattern of the joint to assess the effect of movement on cartilage wear. Changes in the thickness of cartilage over time can be determined so that therapies can be provided. The amount of cartilage tissue that has been lost, for example as a result of arthritis, can be estimated.Type: ApplicationFiled: March 21, 2016Publication date: September 22, 2016Inventors: Philipp Lang, Daniel Steines, Eugene J. Alexander, Thomas P. Andriacchi

Patent number: 9314342Abstract: A method of implanting a knee replacement system in a leg with a femur and a tibia of a patient can include, implanting a femoral component onto a condyle of the femur and placing a trial tibial component on a tibial plateau of the tibia. The tension of a posterior cruciate ligament can be adjusted. The tension of an anterior cruciate ligament can be adjusted. The posterior position of the trial tibial component can be adjusted. The knee condition at toe off onset can be simulated during walking.Type: GrantFiled: December 17, 2012Date of Patent: April 19, 2016Assignee: Biomet Manufacturing, LLCInventors: Thomas P.

Patent number: 7804998Abstract: A markerless motion capture system is provided for measurements accurate enough for biomechanical, clinical, sport, entertainment, animation, game and movie, design, ergonomics, surveillance applications. The system has multiple cameras distributed around a viewing volume. The cameras allow for the creation of three-dimensional mesh representations of an object dynamically moving within the viewing volume. A model of the object that incorporates specific morphological and kinematic model information (including soft joint constraints) is then matched to the captured three-dimensional mesh representations. The matching routine aims to embed the model into each of the three-dimensional representations using (i) iterative closest point or simulated annealing algorithms and (ii) using soft joint constraints. This unique combination of routines offers a simple, time-efficient, accurate and thus more meaningful assessment of movements.Type: GrantFiled: March 9, 2007Date of Patent: September 28, 2010Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Lars Mündermann, Stefano Corazza, Thomas P.

Publication number: 20090076371Abstract: Methods for assessing the condition of a cartilage in a joint and assessing cartilage loss, particularly in a human knee, are disclosed. In one method, a method for modeling healthy cartilage, the method includes measuring the distance between each of at least two points on an articular cartilage surface corresponding to margins of a defect and a corresponding point on the sub-chondral bone surface, and interpolating a reconstructed cartilage boundary. In a second method, a method for generating a three-dimensional approximation of healthy cartilage, the method includes determining a set of distances between at least three points on a first articular surface corresponding to margins of a defect and at least three corresponding points on a second cartilage surface, and approximating a reconstructed cartilage surface.Type: ApplicationFiled: November 25, 2008Publication date: March 19, 2009Applicant: THE BOARD OF TRUSTEES OF THE LELAND STANFORD JUNIOR UNIVERSITYInventors: Philipp Lang, Daniel Steines, Eugene J.
