Prostheses, methods and related instrumentation for treating disorders of the knee by displacing a connective tissue acting on the patella to alter the location, angle or magnitude of forces exerted by the tissue on the patella so as to achieve a therapeutic effect in patellofemoral compartment of the knee.

The implants of the invention relate to improved implants formed using additive manufacturing techniques, the implants including a hemispherical cup portion, and an ischium flange, a pubic ramus flange and an ilium flange, each flange extending outwardly from the perimeter of the hemispherical cup portion, wherein the implant surface includes an area of integrally formed three dimensional scaffold on the bone apposition surfaces of the cup portion and on a bone apposition surface of at least one of the flanges of the implant. The invention also relates to implants with different surface texture and alignment features, together with methods for the manufacture of patient-specific implants of the invention.

Femoral heads, mobile inserts, acetabular components, and modular junctions for orthopedic implants, e.g., hip replacement implants, and methods of using femoral heads, mobile inserts, acetabular components, and modular junctions for orthopedic implants are provided. Prosthetic femoral heads, mobile inserts, and acetabular components are provided that can alleviate soft tissue impingement, reduce implant wear, and/or reduce frictional torque. Modular junctions are provided that can minimize the incidence of loosening and micromotion that can occur at modular junctions of orthopedic implants.

An implant comprises a body including an articulation surface and an opposed bone contact surface and defining a predetermined thickness therebetween. The body defines at least one anchor hole sized and configured to receive an anchor therethrough. The anchor is configured to couple soft tissue to the body. The anchors are coupled to soft tissue and passed through the at least one anchor hole to anchor the soft tissue to the body of the implant.

A method of assembling a mobile bearing acetabular component of a prosthetic hip joint is disclosed. The method includes mounting an acetabular cup insert to an acetabular cup. The method includes concurrently repositioning the acetabular cup insert deeper into an interior of the acetabular cup and repositioning the acetabular cup insert outside of an outline of the acetabular cup.

Selectively placed implants are specifically configured and dimensioned to address pathologies of the shoulder joint arising from improper force distribution. By using appropriately sized and positioned implants as described herein, displacement of targeted connective and muscle tissues acting on the shoulder is accomplished in order to realign force vectors and/or alter moment arms loading the joint to achieve therapeutic effects without cutting bone and with minimal cutting of the connective tissues.

An orthopedic implant with an inferior portion having a tibia contact surface configured to extend over a tibia; a superior portion opposite to the inferior portion having a tendon contact surface configured to change a position of a patellar tendon by lifting or tilting the patellar tendon when the curved surface of the first portion is engaged with the tibia; a fixation mechanism adapted to attach the orthopedic implant to the tibia; and an adjustment mechanism adapted to change a distance between the tendon contact surface and the tibia contact surface. The invention also includes a method for repositioning a patellar tendon of a patient.

A method for imparting tension across a human knee joint which includes a femur bone, a tibia bone, a patella bone, a patellar tendon, and ligaments, wherein the ligaments and patellar tendon are under anatomical tension to connect the femur and tibia together, creating a load-bearing articulating joint. The method includes: providing a tensioning device, including: a baseplate; a top plate; and a linkage interconnecting the baseplate and the top plate and operable to move the tensioning device between retracted and extended positions, wherein the top plate is pivotally connected to the linkage so as to be able to freely pivot about a pivot axis; positioning the tensioning device between the femur and the tibia; applying an actuating force to the linkage to move the tensioning device towards the extended position, so as to impart a controlled separating force driving the femur and tibia apart to extend the ligaments.

An improved modular rotational device includes a first and second threaded coupler for affixation along the stem of an endoprosthetic device, for example, a humeral prosthesis or a femoral prosthesis. The rotational device axis of rotation is coaxial with the stem, and its axis of rotation is located in close proximity to the intramedullary stem of the prosthesis or in close proximity to the distal articulation of the prosthesis. A housing has a proximal and distal end with an axial bore therethrough for receiving an elongated stem of the device. A lobe ring may be utilized to limit the axis of rotation of the device. Additional endoprosthetic devices may be attached to male or female threaded couplers, or to Morse tapers. A plurality of suture attachments facilitates attachment of soft tissue thereto.

Embodiments of the present disclosure relate generally to an orbital floor implant (10). One embodiment provides an implant with a first surface that is a fully porous, bone-side layer (16) and a second surface that is a non-porous, orbital content-side layer (18). The implant material itself may be polymeric material throughout, without the need for an embedded mesh or other support matrix. The implant is provided in a pre-shaped configuration and is of a material that allows it to be bent for shaping purposes. An extending tab (12) with eyelet portion/opening (14) can enhance securement options to a patient's bone.
