Abstract

A prosthetic femoral component (40) for the knee joint has a body (41,42) defined between elongate articulation and securement surfaces (43; 44,45), the articulation surface (43) being convexly spherically shaped and the securement surface having major and minor areas at opposite end portions, the major area (44) being essentially concavely spherically concentric with the articulation surface to form a shell body part (41), and the minor area (45) being essentially planar extending chordally of the articulation surface. A bone-penetrating pin (46) preferably extends radially from the major securement surface area in a direction parallel to the longitudinal direction of the neighbouring minor area. A related surgical tool (50) for shaping the femoral condyle has a rotary cutter (52) to provide a cut bone surface complementing the component major area, and a guide spigot (53) projecting adjustably coaxially within the cutter.
