Comparative StudyDifferences in short-term complications between unicompartmental and total knee arthroplasty: a propensity score matched analysis.
Knee arthroplasty has emerged as an effective treatment for end-stage gonarthrosis. Although total knee arthroplasty remains the gold standard, unicompartmental knee arthroplasty is an appropriate alternative for select patients. We sought to use a large, heterogeneous national database to identify differences in thirty-day complication rates between unicompartmental and total knee arthroplasty as well as to identify risk factors for complications. ⋯ Therapeutic Level III.

The effect of timing of manipulation under anesthesia to improve range of motion and functional outcomes following total knee arthroplasty.
Manipulation under anesthesia has been reported to improve range of motion when other rehabilitative efforts fail to obtain adequate motion after total knee arthroplasty. The purpose of this study was to evaluate the effects of the timing of the manipulation on knee range of motion and clinical outcomes. ⋯ Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

The Effect of C-Arm Position on Radiation Exposure During Fixation of Pediatric Supracondylar Fractures of the Humerus.
Closed reduction and percutaneous pinning of a pediatric supracondylar fracture of the humerus requires operating directly next to the C-arm to hold reduction and perform fixation under direct imaging. This study was designed to compare radiation exposure from two C-arm configurations: with the image intensifier serving as the operating surface, and with a radiolucent hand table serving as the operating surface and the image intensifier positioned above the table. ⋯ In contrast to traditional teaching regarding radiation exposure, neither C-arm configuration-with the image intensifier serving as the operating surface or with the image intensifier positioned above a radiolucent hand table-was shown to be clearly safer for pediatric supracondylar humeral fracture fixation.

Review Multicenter StudyImpact of Resident Involvement on Orthopaedic Surgery Outcomes: An Analysis of 30,628 Patients from the American College of Surgeons National Surgical Quality Improvement Program Database.
Operative procedural training is a key component of orthopaedic surgery residency. The influence of intraoperative resident participation on the outcomes of surgery has not been studied extensively using large, population-based databases. ⋯ Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Multicenter Study Comparative StudyThirty-Day Morbidity After Single-Level Anterior Cervical Discectomy and Fusion: Identification of Risk Factors and Emphasis on the Safety of Outpatient Procedures.
Risk factors for complication after single-level anterior cervical discectomy and fusion remain poorly defined. The purpose of this study was to identify the incidence and risk factors for complication from a large, prospectively collected database, with a separate emphasis on the safety of outpatient procedures. ⋯ Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
