Abstract
A device for treating a human joint having damaged articular surfaces, for example an arthritic joint, comprises a cap of concavo-convex lenticular form and constructed of a bio-compatible material. The function of the cap is to mould cartilage covering the damaged articular surfaces. The radius of curvature of the convex surface and of the concave surface may be numerically the same or the radius of the convex surface may be greater than the radius of the concave surface according to the particular joint to be treated.
