The primary objective of this study was to determine whether thermal stress potentiates the chondrotoxic effect of bupivacaine, resulting in decreased articular chondrocyte viability compared with exposure to bupivacaine alone. ⋯ Intra-articular injection of bupivacaine after arthroscopic procedures during which cartilage is exposed to elevated temperatures, such as with prolonged use of radiofrequency probes, may increase the risk of chondrocyte toxicity.

To evaluate the effect of entry and exit points of the coracoid tunnel on load to failure and mode of failure, to reduce the incidence of coracoid fractures and acromioclavicular joint repair failures. ⋯ Proper trajectory of the drill during formation of a coracoid bone tunnel can help reduce the risk of coracoid process fracture and repair failure.
