Abstract
The invention relates to a method of determining the sagittal rotation of a patient's pelvis based on a standard anterior posterior X-ray-image with known image parameters and a calibration of the image, for example by using at least one King-Mark calibration object. The angle of the pelvic rotation is determined between a pelvic plane which is orthogonal to the midsagittal plane of the pelvis, and the image plane of the X-ray-image. Assuming the patient's position shown on the X-ray-image represents a standard neutral position, the X-ray-image plane can be used as a functional reference plane for further calculations, for example during hip-replacement surgery. The present invention further relates to a corresponding computer program and system.

The bone characteristic information may be used to determine, inter alia, whether a cementless implant may be supported and/or a bone preparation process for an implant.

Abstract
An optical tracking system is provided. The optical tracking system comprises an autoclavable fiducial marker assembly including an opaque housing, a light source, a window panel configured to refract light rays from the light source therethrough, and a metallized coating forming a hermetic seal at an interface of the window panel and the opaque housing. The fiducial marker assembly is configured to shield a peripheral edge of the window panel from the light rays. The system further comprises a tracking device comprising at least two optical sensors configured to detect a position of a light ray emitted by the light source. The system further comprises a processor configured to receive the position of the light rays from the optical sensors, shift the position of each light ray based on a calculated refraction deviation, and triangulate the location of the light source based on the shifted position of each light ray.

Abstract
A system for harvesting a tendon graft is disclosed, including a retractor, a guide and a harvesting tool. The retractor is collapsible and upon release, becomes self-supporting to hold open an anatomic space developed in a patient above the tendon. A guide assembles with the retractor to orient a guide shaft along the retractor and thereby the anatomic space. The harvesting tool includes a working end with a blade edge for cutting into the tendon. The harvesting tool defines a contoured surface for engaging and translating along the guide shaft while assembled to the retractor. The guide shaft and contoured surface limit the trajectory and translation extent of the harvesting tool along and into the tendon.

Abstract
Tissue repair devices described herein allow for meniscal root repair with sutures and anchors delivered by a needle. The needle houses two deployable anchors, each connected to a separate suture. The device also includes a push mechanism that allows for reliable anchor deployment through the needle. The needle can have various degrees of curvature to access the superior or inferior surfaces of the meniscal roots. Each advancement of the push mechanism by the surgeon expels an individual suture/anchor construct from the distal tip of the needle at the desired location.

Abstract
Disclosed herein is a system and method providing a tool for use by a surgeon, either preoperatively or intra-operatively, to visualize the effect of and select optimal design and placement of an implant used in a total hip replacement surgical procedure on both the range-of-motion of the patient's leg and the jump distance of the implant. This will assist the surgeon in determining the optimal selection and placement of the implant to provide the best outcome for the patient.
