The Fate of Spacers in the Treatment of Periprosthetic Joint Infection
Conclusions: The commonly held belief that two-stage exchange arthroplasty carries a high success rate for the eradication of periprosthetic joint infection may need to be reexamined. A considerable number of patients undergoing the first stage of a two-stage procedure do not undergo a subsequent reimplantation for a variety of reasons or require an additional spacer exchange in the interim. Reports on the success of two-stage exchange should account for the mortality of these patients and for patients who never undergo reimplantation. Level of Evidence: Therapeutic Level IV. See Instructions for Authors for a complete de...

Consumer Choice Between Hospital-Based and Freestanding Facilities for Arthroscopy: Impact on Prices, Spending, and Surgical Complications
Conclusions: Reference-based benefits increase consumer sensitivity to price differences between freestanding and hospital-based surgical facilities. Clinical Relevance: This study shows that the implementation of reference-based benefits does not result in a significant increase in measured complication rates for those subject to reference-based benefits.

A Validated Orthopaedic Surgical Simulation Model for Training and Evaluation of Basic Arthroscopic Skills
Conclusions: A simulation model was successfully designed to teach and evaluate basic arthroscopic skills showing good construct validity. This arthroscopic simulation model is inexpensive, valid, and reliable and has the potential to be implemented in other training programs. (Source: The Journal of Bone and Joint Surgery)

The Current State of Screening and Decolonization for the Prevention of Staphylococcus aureus Surgical Site Infection After Total Hip and Knee Arthroplasty
The most common pathogens in surgical site infections after total hip and knee arthroplasty are methicillin-sensitive Staphylococcus aureus (MSSA), methicillin-resistant S. aureus (MRSA), and coagulase-negative staphylococci. Patients colonized with MSSA or MRSA have an increased risk for a staphylococcal infection at the site of a total hip or knee arthroplasty. Most colonized individuals who develop a staphylococcal infection at the site of a total hip or total knee arthroplasty have molecularly identical S. aureus isolates in their nares and wounds. Screening and nasal decolonization of S. aureus can potentially redu...

What Components Comprise the Measurement of the Tibial Tuberosity-Trochlear Groove Distance in a Patellar Dislocation Population?
Conclusions: Because the tibial tuberosity-trochlear groove distance is affected more by knee rotation than by tubercle malposition, its use as an indicator for tibial tubercle transfer may not be appropriate. Clinical Relevance: Surgical decisions of tibial tubercle transfer should be made after the careful analysis of several underlying factors of patellar dislocation.

Potential Risk to the Superior Gluteal Nerve During the Anterior Approach to the Hip Joint: An Anatomical Study
Conclusions: Coagulation of the ascending branch of the lateral circumflex femoral artery and the placement of retractors during the anterior approach to the hip joint carry the potential risk for injury to the motor nerve branches supplying the tensor fasciae latae. Clinical Relevance: During the anterior approach, the ligation or coagulation of the ascending branch of the lateral circumflex femoral artery should not be performed too close to the point where it enters the tensor fasciae latae. The nerve branches to the tensor fasciae latae could also be compromised by the extensive use of retractors, broaching of the fem...

Genetic Risk for Aortic Aneurysm in Adolescent Idiopathic Scoliosis
Conclusions: Clinically actionable pathogenic mutations in genes associated with adolescent idiopathic scoliosis and aortic aneurysm are rare in patients with adolescent idiopathic scoliosis who are not suspected of having these disorders, although variants of unknown significance are relatively common. Clinical Relevance: Routine genetic screening of all patients with adolescent idiopathic scoliosis for mutations in clinically actionable aortic aneurysm disease genes is not recommended on the basis of the high frequency of variants of unknown significance. Clinical evaluation and family history should heighten indication...

Time Trade-Off as a Measure of Health-Related Quality of Life: Long Bone Nonunions Have a Devastating Impact
Conclusions: Patients diagnosed with a long bone nonunion have a very low health-related quality of life. We found that this single cohort’s mean utility score was 0.68. This result is well below that of illnesses such as type-I diabetes mellitus (0.88), stroke (0.81), and acquired immunodeficiency syndrome (0.79). We found that patients with forearm nonunions had the lowest utility scores. Level of Evidence: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Open Bankart Repair for the Treatment of Anterior Shoulder Instability without Substantial Osseous Glenoid Defects: Results After a Minimum Follow-up of Twenty Years
Conclusions: Open Bankart repair provides good results twenty years after surgery in terms of subjective and objective outcome measurements. However, the long-term failure rate remains high despite the exclusion of substantial osseous glenoid defects. Recurrence of instability seems to be associated with an increased shoulder-specific activity level. Level of Evidence: Therapeutic Level IV.
