## Description

The AK-L-II Liner is available in both highly cross-linked polyethylene (HXLPE) and ultra-high-molecular-weight polyethylene (UHMWPE) variants. The liners are designed to lock into the shell by means of a circumferential ring that engages the shell's mating groove. Rotational stability may be achieved when the shell's anti-rotational barbs interlock with the insert's scallops.
