Evaluation of the Role for Synovial Aspiration in the Diagnosis of Aseptic Loosening After Total Knee Arthroplasty
Conclusions: Although synovial fluid aspirates in patients with aseptic loosening and those with normal total knee arthroplasties did not differ, synovial fluid aspirate characteristics differed among categories of aseptic failure. As a result, the optimal diagnosis of periprosthetic infection on the basis of synovial aspiration results may need to utilize different cutoff values depending on the alternative mode of failure being considered. Large prospective studies will be necessary to validate these threshold values. Level of Evidence: Diagnostic Level II. See Instructions for Authors for a complete description of leve...

Extensor Mechanism Injuries of the Knee: Demographic Characteristics and Comorbidities from a Review of 726 Patient Records
Conclusions: Females with an extensor mechanism injury are more likely to sustain a patellar fracture compared with males. Younger males are more likely to sustain a patellar fracture or patellar tendon rupture; however, we found that 43% of the patellar tendon ruptures were in patients over the age of forty. Medical comorbidities were common with tendon ruptures, and we found that they were significantly more common in females than in males. Clinical Relevance: Surgeons treating female patients with a tendinous extensor mechanism disruption should have a low threshold to initiate a medical work-up in search of a possible...

Extendible Prostheses for Children After Resection of Primary Malignant Bone Tumor: Twenty-seven Years of Experience
Conclusions: Although limb lengthening with an extendible endoprosthesis seems to be effective, many children have related complications. These data will be a source of preoperative information for children and parents, and will provide a benchmark for further clinical improvements. Level of Evidence: Therapeutic Level IV.

Shilla Growth Guidance for Early-Onset Scoliosis: Results After a Minimum of Five Years of Follow-up
Conclusions: The Shilla growth guidance technique is a method of scoliosis treatment that allows spinal growth while controlling the deformity without scheduled repeated surgical procedures. The complication rate is high (73%) but acceptable, and children with a wide variety of diagnoses can be safely treated with the Shilla procedure. Level of Evidence: Therapeutic Level IV.

Humeral Head Arthroplasty and Meniscal Allograft Resurfacing of the Glenoid: A Concise Follow-up of a Previous Report and Survivorship Analysis
Abstract: The two to five-year results of humeral head arthroplasty and lateral meniscal allograft resurfacing of the glenoid in patients fifty-five years of age or younger were previously reported by the senior author (M.A.W.). The purpose of the present study was to report the survival rate, clinical findings, and radiographic results of the original thirty shoulders (thirty patients) followed for a mean duration of 8.3 years (range, five to twelve years). The scores on the visual analog scale for pain, American Shoulder and Elbow Surgeons scoring system, and Simple Shoulder Test were significantly improved at the latest...

Prognostic Indicators for Recurrent Symptoms After a Single Corticosteroid Injection for Carpal Tunnel Syndrome
Conclusions: A single injection achieved symptom relief in 79% of patients at six weeks; these results were maintained in 31% of patients at twelve months. Diabetic patients were at higher risk of symptom recurrence. Level of Evidence: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Anti-Osteoporotic Therapy After Fragility Fracture Lowers Rate of Subsequent Fracture: Analysis of a Large Population Sample
Conclusions: Treatment with anti-osteoporotic therapy after a fragility fracture leads to a 40% decrease in the three-year risk of subsequent fracture, when adjusted for age and sex. Initiation of anti-osteoporotic therapy following a fragility fracture can prevent a subsequent fracture over the following three years in approximately one of every twenty-seven patients treated. Level of Evidence: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence. (Source: The Journal of Bone and Joint Surgery)

Pelvic Fixation in Adult and Pediatric Spine Surgery: Historical Perspective, Indications, and Techniques: AAOS Exhibit Selection
Abstract: Achieving solid osseous fusion across the lumbosacral junction has historically been, and continues to be, a challenge in spine surgery. Robust pelvic fixation plays an integral role in achieving this goal. The goals of this review are to describe the history of and indications for spinopelvic fixation, examine conventional spinopelvic fixation techniques, and review the newer S2-alar-iliac technique and its outcomes in adult and pediatric patients with spinal deformity. Since the introduction of Harrington rods in the 1960s, spinal instrumentation has evolved substantially. Indications for spinopelvic fixation a...

Tibial Plateau Fracture Characteristics: Computed Tomography Mapping of Lateral, Medial, and Bicondylar Fractures
Conclusions: Tibial plateau fracture maps show recurrent patterns of fracture lines, revealing four major fracture characteristics. An understanding of these recurrent features of tibial plateau fractures can aid surgeons during diagnosis, preoperative planning, and execution of surgical strategies.

Thromboembolism After Intramedullary Nailing for Metastatic Bone Lesions
Conclusions: There is a high rate of VTE among those with skeletal metastatic disease who undergo intramedullary nailing, even while receiving postoperative thromboembolic prophylaxis. Current anticoagulation protocols may be inadequate. Wound-complication risk with anticoagulant use in this population is low and should not be a deterrent to adequate anticoagulant use for this population. Level of Evidence: Prognostic Level IV.
