Abstract
A construct for repairing articular cartilage defects includes a cap member and a base member. The cap member has an upper section and a stem depending from a central region thereof. The upper section includes a peripheral region. The stem includes a cavity. The base member has first and second ends, the first end including an annular recess dimensioned such that the stem is receivable therein. The first end also includes an annular edge positioned laterally outwardly from the annular recess, for abutting and supporting the peripheral region of the upper section when the stem is received in the annular recess. The base member further includes an island which is surrounded by the annular recess and receivable in the cavity of the stem, such that the island is abuttable with and may thereby support the central region of the upper section when the stem is received in the annular recess.
