Randomized Controlled TrialHighly Cross-Linked Polyethylene Reduces Wear and Revision Rates in Total Hip Arthroplasty: A 10-Year Double-Blinded Randomized Controlled Trial.
Highly cross-linked polyethylene (XLPE) was developed to address the problem of wear and osteolysis associated with metal-on-conventional ultra-high molecular weight polyethylene (UHMWPE) bearing surfaces. The purpose of this study was to compare in vivo wear rates and clinical and radiographic outcomes between XLPE and UHMWPE in a prospective double-blinded randomized controlled trial with a minimum of 10 years of follow-up. ⋯ Therapeutic Level I.

Comparative StudyPostoperative CT Is Superior for Acetabular Fracture Reduction Assessment and Reliably Predicts Hip Survivorship.
Postoperative pelvic radiographs are routinely used to assess acetabular fracture reduction. We compared radiographs and computed tomography (CT) with regard to their ability to detect residual fracture displacement. We also determined the association between the quality of reduction as assessed on CT and hip survivorship and identified risk factors for conversion to total hip arthroplasty (THA). ⋯ Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Randomized Controlled TrialBlood Conservation Using Tranexamic Acid Is Not Superior to Epsilon-Aminocaproic Acid After Total Knee Arthroplasty.
Epsilon-aminocaproic acid (EACA) and tranexamic acid (TXA) are synthetic amino acid derivatives that interfere with fibrinolysis, promoting hemostasis by pharmacological means. Although both drugs have been shown to decrease blood loss with a minimal risk of thromboembolic adverse events following cardiac and vascular surgery, we are aware of only 1 published trial that directly compared the antifibrinolytic effects of EACA with those of TXA after total knee arthroplasty (TKA). The primary aim of this prospective, randomized, controlled trial was to determine whether TXA provides superior blood conservation following TKA compared with that provided by EACA. ⋯ Therapeutic Level I.

Condyle-Specific Matching Does Not Improve Midterm Clinical Outcomes of Osteochondral Allograft Transplantation in the Knee.
Condyle-specific matching for osteochondral allograft transplantation (OCA) pairs donor and recipient condyles in an attempt to minimize articular incongruity. While the majority of cartilage defects are located on the medial femoral condyle, lateral femoral condyles are more commonly available as a graft source. The purpose of this study was to compare the clinical outcomes of patients treated with non-orthotopic (lateral-to-medial condyle or medial-to-lateral condyle) OCA with those treated with traditional orthotopic (medial-to-medial condyle or lateral-to-lateral condyle) OCA. We hypothesized that clinical outcomes would be similar between groups at midterm follow-up. ⋯ Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
