Randomized Controlled Trial Multicenter Study
Better outcome from arthroscopic partial meniscectomy than skin incisions only? A sham-controlled randomised trial in patients aged 35-55 years with knee pain and an MRI-verified meniscal tear.
Compare arthroscopic partial meniscectomy to a true sham intervention. ⋯ We found greater improvement from arthroscopic partial meniscectomy compared with skin incisions only at 2 years, with the statistical uncertainty of the between-group difference including what could be considered clinically relevant. Because of the study being underpowered, nearly half in the sham group being non-blinded and one-third crossing over to surgery, the results cannot be generalised to the greater patient population.

Randomized Controlled Trial
Training approaches for the deployment of a mechanical chest compression device: a randomised controlled manikin study.
To evaluate the effect of training strategy on team deployment of a mechanical chest compression device. ⋯ Pit-crew training, compared with standard training, did not improve team deployment of a mechanical chest device in a simulated cardiac arrest scenario.
