ABSTRACT:
A method of repairing arthritic joints in which the bone surfaces of a knee, hip, shoulder, elbow or other articulation are cleaned of the inflammation caused by the arthritis without removing any of the bone of the joint, and then inserting into the joint a thin, dished bearing member of woven, high tensile strength material impregnated with high molecular weight polyethylene or equivalent material, and cementing one face thereof to the cleaned surface of the bone of one of the joint members, the opposite face of the bearing member being extremely smooth and polished so as to slide easily against the cleaned bone surface of the other joint member.
In preparing the bearing member, a hard metal powder, finely divided, of low thermal expansion and high corrosion and acid resistance, is intimately mixed with a colloidal dispersion of the polyethylene material and applied, in several coatings, to the surface of the bearing member which will slide against the aforesaid bone surface of the other joint member, and the last coating is polished until adequately smooth.
