To review the effect of patient decision aids for adults making treatment decisions regarding the management of chronic musculoskeletal pain. ⋯ Decision aids may improve patients' knowledge about treatment options for chronic musculoskeletal pain but largely did not impact other outcomes. Future efforts should focus on improving the effectiveness of decision aids and incorporating nonpharmacologic and nonsurgical management options.

The relationship between preexisting osteoarthritic pain and subsequent post-total knee arthroplasty (TKA) pain is not well defined. This knowledge gap makes diagnosis of post-TKA pain and development of management plans difficult and may impair future investigations on personalized care. Therefore, a set of diagnostic criteria for identification of acute post-TKA pain would inform standardized management and facilitate future research. ⋯ The diagnostic criteria created are proposed to define the nature of acute pain observed in patients following TKA.

An ultrasound-guided interfascial injection, which targets the space between the epimysia, is often performed for myofascial neck and shoulder pain. However, the relationship between the injection volume and clinical effectiveness has been controversial. We conducted an anatomical study with cadavers to measure the distribution of a small amount of pigment solution injected into the interfascial space. ⋯ A pigment solution comprising as little as 1.0 mL injected under ultrasound guidance separated two adjacent muscles and spread to the wide area within the interfascial space. The difference in the pigment distribution area between the two adjacent muscles can be explained by the path made by the injection needle and several layers of fascia between the epimysium.
