Joint prosthesis (1) with a cup-shaped supporting part (2) in whose interior a ceramic insert (3) is fastened by conical clamping. Clamping surface (6) of insert (3) runs at an angle (.alpha.) to clamping surface (7) of supporting part (2).

Joint prosthesis

Disclosed is a hip joint socket for insertion into bone tissue, having an outer metal shell and an inner antifriction liner. The antifriction liner is fixed in the metal shell by means of a taper lock. To safeguard the socket insert and antifriction liner against misalignment and separation, and enable a non-destructive removal of the liner and replacement thereof, the angle (.alpha.) of the taper lock of the liner in the shell is between 10.degree. and 25.degree..
