Marijuana-dependent patients may face higher infection rates following knee and shoulder arthroscopy

Patients who are dependent on marijuana may face higher infection rates following knee and shoulder arthroscopy-;a minimally invasive surgery in which a small camera is inserted to diagnose and sometimes treat injury-;according to a study presented at the Scientific Forum of the American College of Surgeons (ACS) Clinical Congress 2022.

Using PearlDiver, a national insurance claims database, researchers from the University of Chicago performed a retrospective study of patients with marijuana dependence who underwent knee or shoulder arthroscopy for the postoperative complications of deep vein thrombosis (DVT), pulmonary embolism (PE), and infection.

“Marijuana has been gaining so much popularity, but it’s a risk factor we aren’t really catching,” said lead study author Sarah Bhattacharjee, MD, who conducted the research while she was a medical student at the University of Chicago. Dr. Bhattacharjee is now a surgical resident in orthopedic and sports medicine at the University of Washington. “The higher infection rate found by this new study should raise a ‘red flag’ for patients and providers and should be discussed along with other risk factors before an arthroscopic procedure.”

Placebo Effect a Major Driver of Pain Reduction in Cannabis Trials

A strong placebo response may be largely responsible for the significant pain reduction observed in clinical trials of cannabis-based therapies, results of a new meta-analysis suggest. Investigators found that while the effect size of cannabinoids on pain intensity was significant, the placebo effect was about the same. “The data from the present meta-analysis, including 1459

Since 2005, diagnoses of cannabis use disorder have increased substantially among VHA patients, as they have in the general population and other patient populations. Possible explanations warranting investigation include decreasing perception of risk, changing laws, increasing cannabis potency, stressors related to growing socioeconomic inequality, and use of cannabis to self-treat pain. Clinicians and the public
