Abstract

Abstract Methods and apparatus for prosthetic knee replacement permit preparation of tibial plateau and femoral condyle surfaces and implant of tibial and femoral protheses components with the use of arthroscopic surgical techniques. The bone surfaces are resected by moving a rotating milling cutter longitudinally across the bone surface and moving the rotating milling cutter substantially laterally across the bone. Cement is supplied between the prostheses and the bone surfaces after positioning of the prostheses on the bone, and cement bonding is enhanced by applying suction to the bone to draw the cement into the bone.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 69 words
A method of implanting a prosthesis in the body comprising the steps of preparing a surface of tissue to engage the prosthesis; placing the prosthesis against the tissue surface; inserting cement between the prosthesis and the tissue surface after the prosthesis is placed against the tissue surface; and applying suction to the tissue to create a vacuum to draw the cement into the tissue to form a mechanical bond.
Claim 2
Independent Claim 69 words
A method of implanting a prosthesis in the body comprising the steps of preparing a surface of tissue to engage the prosthesis; placing the prosthesis against the tissue surface; inserting cement between the prosthesis and the tissue surface after the prosthesis is placed against the tissue surface; and applying suction to the tissue to create a vacuum to draw the cement into the tissue to form a mechanical bond.
Claim 3
Dependent Claim 25 words
A method of implanting a prosthesis in the body as recited in claim 1 wherein said cement inserting step includes inserting cement through the prosthesis.
Claim 4
Dependent Claim 37 words
A method of implanting a prosthesis as recited in claim 1 wherein the prosthesis has a recess therein forming, with the tissue surface, a chamber and said step of inserting cement includes injecting cement in the chamber.
Claim 5
Dependent Claim 28 words
A method of implanting a prosthesis as recited in claim 1 wherein the tissue is bone and said step of applying suction includes applying suction to the bone.
Claim 6
Independent Claim 44 words
A method of implanting a prosthesis on a bone surface in the body comprising the steps of applying cement between the prosthesis and the bone surface; and applying suction to the bone to draw the cement into the bone to form a mechanical bond.
Claim 7
Independent Claim 44 words
A method of implanting a prosthesis on a bone surface in the body comprising the steps of applying cement between the prosthesis and the bone surface; and applying suction to the bone to draw the cement into the bone to form a mechanical bond.
Claim 8
Dependent Claim 45 words
A method of implanting a prosthesis as recited in claim 4 wherein the prosthesis has a recess therein forming, with the bone surface, a chamber and said step of applying cement includes inserting cement into the chamber with the prosthesis placed against the bone surface.
