Ligament Graft Fixation — US5702398A
What problem does it address?
Ligament reconstruction requires secure fixation of a ligament graft to bone. Reliable fixation is important for maintaining graft position and stability during the healing process.
What was developed?
This patent describes a fixation system designed to secure a ligament graft within a bone tunnel. The system uses a fixation device that engages the graft and bone to support stable positioning following ligament reconstruction.
Why is it relevant to orthopedic surgery?
The invention addresses an important technical aspect of ligament reconstruction: achieving secure graft fixation while the reconstructed ligament integrates with the surrounding bone.

Dynamic Spacer for Total Knee Arthroplasty – US20050020941A1
What problem does it address?
During total knee replacement, achieving appropriate balance between the soft tissues and the spaces within the knee is important for joint stability, movement and overall function after implantation.
What was developed?
This patent describes a dynamic spacer system designed for use during total knee arthroplasty. The instrument allows the surgeon to evaluate the space between the femur and tibia under controlled soft-tissue tension during different stages of the procedure.
Why is it relevant to knee replacement?
The technology addresses one of the technical challenges of total knee replacement: helping the surgeon assess joint spacing and soft-tissue balance before the final components of the knee prosthesis are implanted.
Inventor: Dr. Samih Tarabichi

Knee Prosthesis for Deep Flexion — US7094259B2
What problem does it address?
Conventional knee replacement designs may limit the mechanics required for activities involving deep knee flexion. This is particularly relevant for patients whose daily or cultural activities involve kneeling, squatting, sitting on the floor or other high-flexion movements.
What was developed?
This patent describes a knee prosthesis designed to accommodate deep flexion, incorporating femoral, tibial and meniscal components with design features intended to support articulation of the reconstructed knee through increased flexion.
Why is it relevant to knee replacement?
The invention addresses implant design in relation to knee movement and deep-flexion function—an area that also became an important focus of Dr. Samih Tarabichi’s clinical research into knee kinematics and functional outcomes after total knee replacement.
Inventor: Dr. Samih Tarabichi
Patent family note: US7455647B2 is the granted patent resulting from the same U.S. application previously published as US20050020941A1. Both records are included here to document the development and grant history of the Dynamic Spacer technology.

Dynamic Spacer for Total Knee Arthroplasty — US7455647B2
What problem does it address?
During total knee replacement, the surgeon must establish appropriate spacing and soft-tissue balance between the femur and tibia. Inadequate balance can affect the stability, alignment and functional movement of the reconstructed knee.
What was developed?
This patent describes a dynamic spacer system for total knee arthroplasty designed to apply controlled distraction between the femur and tibia. The device assists the surgeon in evaluating the joint space and soft-tissue tension during the procedure.
Why is it relevant to knee replacement?
The invention provides a surgical instrument for assessing knee balance before final implant positioning, supporting intraoperative decision-making during total knee arthroplasty.

Revision Joint Replacement Device and Method — WO2015105855A1
What problem does it address?
Revision joint replacement can be more complex than primary joint replacement because previous surgery, implant removal and bone loss may alter or remove anatomical landmarks normally used by the surgeon to determine implant position and restore the joint.
What was developed?
This patent describes a revision joint replacement device and method that uses preoperative imaging and planning to help determine anatomical reference information for the revision procedure. The technology is designed to assist with positioning components and reconstructing the joint when conventional anatomical references may no longer be reliable.
Why is it relevant to revision joint replacement?
The invention addresses one of the major technical challenges in revision surgery: reconstructing a previously operated joint when normal anatomy has been altered. It provides a planning and surgical approach intended to support more precise reconstruction and component positioning.
Inventors: Dr. Samih Tarabichi and Dr. Mohamed M. Elfekky

Revision Joint Replacement Device and Method — EP3091910A1
What problem does it address?
Revision joint replacement surgery can be challenging when previous implants, bone loss or changes in anatomy make the original joint landmarks difficult to identify. These changes can complicate surgical planning and accurate reconstruction of the joint.
What was developed?
This patent describes a device and method for revision joint replacement using preoperative imaging and anatomical reference information to assist with planning and positioning during revision surgery. The approach is intended to help reconstruct the joint when conventional anatomical landmarks have been altered by previous surgery.
Why is it relevant to revision joint replacement?
The technology addresses the need for reliable anatomical references in complex revision procedures, supporting surgical planning and component positioning when reconstructing a previously replaced joint.
Inventors: Dr. Samih Tarabichi and Dr. Mohamed M. Elfekky
Patent family note: The Revision Joint Replacement Device and Method was pursued through multiple international and national patent records. WO2015105855A1, EP3091910A1 and US11134958B2 represent related publications within this innovation’s international patent history.

Revision Joint Replacement Device and Method — US11134958B2
What problem does it address?
Complex revision joint replacement can involve substantial changes to the patient’s anatomy following previous surgery, implant removal or bone loss. This can make it difficult to identify the original anatomical references needed to restore joint position during reconstruction.
What was developed?
This patent describes a revision joint replacement device and method that uses preoperative imaging and planning to establish reference information for the revision procedure. The technology is designed to assist the surgeon in determining implant positioning and reconstructing the joint when normal anatomical landmarks have been altered.
Why is it relevant to revision joint replacement?
The invention addresses surgical planning and reconstruction challenges encountered in revision arthroplasty, particularly when previous joint replacement has changed the anatomy available for conventional surgical referencing.

Tibial Component for a Knee Prosthesis — US20230329874A1
What problem does it address?
The tibial component is a critical part of a total knee replacement implant. Its design can influence how the prosthetic knee accommodates the patient’s anatomy, distributes forces and functions during movement.
What was developed?
This patent describes a tibial component for a knee prosthesis incorporating specific structural and geometrical design features intended for use as part of an artificial knee joint.
Why is it relevant to knee replacement?
The invention focuses directly on implant design, extending Dr. Samih Tarabichi’s innovation work from surgical instrumentation and revision solutions to the components used in knee replacement itself.
