Liposomal Bupivacaine Infiltration Versus Bupivacaine Hydrochloride for the Management of Unilateral Total Knee Arthroplasty in Geriatric Patients at a 287-Bed Community Hospital.

Geriatric patients receiving total knee arthroplasty (TKA) are found to have similar postoperative complications, functional scores, and perioperative mortality, as compared to younger patients. Conversely, geriatric patients often have longer lengths of stay. Periarticular injection (PAI) of liposomal bupivacaine (LB) as part of the multimodal pain management strategy is thought to improve recovery, however, mixed comparative efficacy data exists for its use in TKA.
