Interposition Arthroplasty with an Achilles Tendon Allograft as a Salvage Procedure for the Elbow

We consider interposition elbow arthroplasty to be a salvage procedure as it neither completely eliminates pain nor restores full function. It may be indicated for young active patients with severe inflammatory or posttraumatic arthritis, especially those with limited elbow motion. Furthermore, we do not recommend this procedure when patients present with preoperative instability on physical examination.
