Risk Factors for Failure After 1-Stage Exchange Total Knee Arthroplasty in the Management of Periprosthetic Joint Infection.
One-stage exchange arthroplasty in the management of periprosthetic joint infection was introduced at our institution. The purpose of this study was to analyze the risk factors of failure after periprosthetic joint infection following total knee arthroplasty treated with 1-stage exchange. ⋯ Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Orthopaedic Faculty and Resident Sex Diversity Are Associated with the Orthopaedic Residency Application Rate of Female Medical Students.
The representation of women in orthopaedics in the United States remains among the lowest in all fields of medicine, and prior research has suggested that this underrepresentation may stem from lower levels of interest among female medical students. Of the many proposed reasons for this lack of interest, the male-dominated nature of the field is one of the most commonly cited. The purpose of this study was to determine the degree to which the representation of women among orthopaedic faculty and residents influences female medical students at that institution to apply for a residency in orthopaedics. ⋯ In this study, we found that increased sex diversity among orthopaedic faculty and residents was associated with a greater likelihood that female medical students at that institution would apply for an orthopaedic residency. These results suggest that at least some of the factors currently impeding female medical student interest in orthopaedics may be modifiable. These findings may have important implications for efforts to improve the sex diversity of the field of orthopaedics going forward.

Multicenter Study Clinical TrialFragility Fractures of the Pelvis Classification: A Multicenter Assessment of the Intra-Rater and Inter-Rater Reliabilities and Percentage of Agreement.
The fragility fractures of the pelvis (FFP) classification was established to address the specific fracture morphology and dynamic instability in the elderly. Although this system is frequently used, data on the intra-rater and inter-rater reliabilities are lacking. ⋯ With moderate to substantial intra-rater and inter-rater reliabilities, the FFP classification forms a solid basis for future clinical investigations. The differentiation of FFP II from FFP III should be evaluated thoroughly, as the initial treatment changes from nonoperative for II to operative for III.

Randomized Controlled TrialA Randomized Clinical Trial Comparing Patellar Tendon, Hamstring Tendon, and Double-Bundle ACL Reconstructions: Patient-Reported and Clinical Outcomes at 5-Year Follow-up.
This randomized clinical trial evaluated the 5-year, disease-specific quality-of-life outcomes of patients treated for anterior cruciate ligament (ACL) deficiency with use of a patellar tendon, single-bundle quadruple-stranded hamstring, or double-bundle hamstring reconstruction. ⋯ Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

Biomechanics of Biodegradable Subacromial Balloon Spacer for Irreparable Superior Rotator Cuff Tears: Study of a Cadaveric Model.
A subacromial balloon spacer is an option to treat irreparable rotator cuff tears. We hypothesized that the balloon would restore glenohumeral contact pressure, the acromion-humeral interval, and deltoid load to intact values after a simulated irreparable supraspinatus tear in a cadaveric model. ⋯ This study supports further investigation of the balloon spacer in comparative clinical studies of surgical options for irreparable rotator cuff tears, with clinically relevant evaluation measures and observation periods.
