Inhibition of Chondrocyte and Synovial Cell Death After Exposure to Commonly Used Anesthetics: Chondrocyte Apoptosis After Anesthetics

Inhibition of Chondrocyte and Synovial Cell Death After Exposure to Commonly Used Anesthetics: Chondrocyte Apoptosis After Anesthetics
Background:

An intra-articular injection of local anesthetics is a common procedure for diagnostic and therapeutic purposes. It has been shown that these agents are toxic to articular cartilage and synovial tissue in a dose- and time-dependent fashion, and in some cases, they may lead to postarthroscopic glenohumeral chondrolysis (PAGCL). However, the role of apoptosis in cell death is still unclear, and the potential role of apoptosis inhibition in minimizing chondrocyte and synovial cell death has not been reported.

Purpose: (1) To quantify the degree of apoptotic cell death in chondrocytes and synovial cells exposed to local anesthetics, and(2) to determine whether caspase inhibition could reduce cell death.

Study Design: Controlled laboratory study.
