Randomized Controlled Trial Multicenter Study Comparative StudyArthroscopic rotator cuff repair with and without acromioplasty in the treatment of full-thickness rotator cuff tears: a multicenter, randomized controlled trial.
The primary objective of this prospective randomized controlled trial was to compare functional and quality-of-life indices and rates of revision surgery in arthroscopic rotator cuff repair with and without acromioplasty. ⋯ Our findings are consistent with previous research reports in which there was no difference in functional and quality-of-life indices for patients who had rotator cuff repair with or without acromioplasty. The higher reoperation rate was found in the group without acromioplasty. Further study that includes follow-up imaging and patient-reported outcomes over a greater follow-up period is needed.

Randomized Controlled Trial Multicenter Study Comparative StudyInterobserver reliability of radial head fracture classification: two-dimensional compared with three-dimensional CT.
The Broberg and Morrey modification of the Mason classification of radial head fractures has substantial interobserver variation. This study used a large web-based collaborative of experienced orthopaedic surgeons to test the hypothesis that three-dimensional reconstructions of computed tomography (CT) scans improve the interobserver reliability of the classification of radial head fractures according to the Broberg and Morrey modification of the Mason classification. ⋯ Although three-dimensional CT led to some small but significant decreases in interobserver variation, there is still considerable disagreement regarding classification and characterization of radial head fractures. Three-dimensional CT may be insufficient to optimize interobserver agreement.

Randomized Controlled Trial Comparative StudyTemperature-sensitive release of prostaglandin E₂ and diminished energy requirements in synovial tissue with postoperative cryotherapy: a prospective randomized study after knee arthroscopy.
Local external cooling of the surgical field after joint surgery is intended to enhance recovery and to facilitate the use of outpatient surgery by reducing pain and improving mobility. We hypothesized that the effects of postoperative cooling and compression after knee arthroscopy would be reflected in changes in the concentrations of metabolic and inflammatory markers in the synovial membrane. ⋯ Local cryotherapy and compression after knee arthroscopy significantly lowered the temperature in the knee postoperatively, and the synovial PGE₂ concentration was correlated with the temperature. Since PGE₂ is a marker of pain and inflammation, the postoperative local cooling and compression appeared to have a positive anti-inflammatory effect.
