The Effect of Nutritional Status in the Treatment of Periprosthetic Joint Infections in Total Hip Arthroplasty.

Background: Periprosthetic joint infections (PJIs) continue to be a complication that plagues arthroplasty. Albumin is a surrogate marker for nutrition as well as chronic inflammation, and hypoalbuminemia increases the risk of complications in arthroplasty. Patients with PJI are at increased risk for malnutrition and complications.

Surgical Versus Nonsurgical Management of Acetabular Fractures With Associated Patterns in Elderly Patients: Factors Affecting Outcomes.

Introduction: Among elderly patients, anterior column posterior hemitransverse (ACPHT) and associated both column (ABC) are common acetabular fracture patterns after low-energy mechanisms. Given the paucity of outcomes data in this cohort, the goal of this study was to determine the favorability of results with surgical versus nonsurgical management. Secondarily, factors linked with poor functional outcomes were assessed.

Outcomes of Pediatric Posterior Cruciate Ligament Reconstruction: A Systematic Review.

Background: Little has been reported in the literature regarding surgical treatment of posterior cruciate ligament (PCL) injuries in pediatric patients.

Purpose/hypothesis: The purpose was to evaluate presentation, injury pattern, outcomes, and complications of surgically managed PCL injuries in pediatric patients. It was hypothesized that pediatric patients would have good patient-reported outcomes and no significant radiographic changes or complications.

Survivorship of the Hip Joint After Acetabulum Fracture.

Purpose: The purposes of this study were to determine the rate of failure of the hip joint after acetabulum fracture and to identify risk factors.

Methods: Acetabulum fractures treated over 17 years at a level-1 trauma center were reviewed. Patient, injury, and treatment factors were assessed regarding possible association with failure of the hip joint: end-stage arthrosis and/or total hip arthroplasty (THA).

Nerve Injury With Acetabulum Fractures: Incidence and Factors Affecting Recovery.

Objectives: To determine factors associated with nerve injury after acetabulum fracture and to evaluate recovery and outcomes.

Design: Retrospective cohort study.

Setting: Level 1 trauma center.

Clinical and Functional Results of 119 Patients With Knee Dislocations.

Objectives: To describe clinical results and functional outcomes of knee dislocations treated with a consistent strategy within our institution.

Design: Retrospective case series.

Setting: Level 1 trauma center.

Can Vascular Injury be Appropriately Assessed With Physical Examination After Knee Dislocation?

Background: Knee dislocations are rare injuries with potentially devastating vascular complications. An expeditious and accurate diagnosis is necessary, as failing to diagnose vascular injury can result in amputation; however, the best diagnostic approach remains controversial.

Questions/purposes: We asked: (1) What patient factors are predictors of vascular injury after knee dislocation? (2) What are the diagnostic utilities of palpable dorsalis pedis or posterior tibial pulses, and the presence of an ankle-brachial index (ABI) of 0.

Acetabular fractures converted to total hip arthroplasties in the elderly: how does function compare to primary total hip arthroplasty?

Objectives: Little data exist regarding the outcomes of total hip arthroplasty (THA) after acetabular fracture treatment failure. We hypothesize that these patients achieve a lower level of function than those who undergo primary THA for osteoarthritis (atraumatic).

Design: Retrospective review.
