Hyperextension following two different designs of fixed-bearing posterior-stabilized total knee arthroplasty.

Purpose: Hyperextension after total knee arthroplasty (TKA) is related to worse functional outcomes. Among the reported predictive factors, it is unclear whether prosthesis design affects postoperative hyperextension. Hence, our objectives were to (1) compare time-dependent changes of the extension angle following multi-radius (MR) and single-radius (SR) TKA and (2) assess predictive factors for the hyperextension.

Contamination Rate of Burnt Necrotic Tissue after Electrocoagulation in Total Knee Arthroplasty.

Background: Periprosthetic joint infection (PJI) is one of the commonly found catastrophic complications after total knee arthroplasty (TKA). Preoperative antibiotic prophylaxis, proper skin cleansing, shortened operative time, and sterility of surgical field and equipment are essential to minimize the risk of PJI. Although bacterial contamination of electrocautery tips has been reported, contamination of residual product of electrocoagulation, burnt necrotic tissue (BNT), is not well known.

Blood loss reduction: effect of different knee prosthesis designs and use of tranexamic acid-a randomized controlled trial.

Purpose: In regard to blood loss in total knee arthroplasty (TKA), the effect of either knee prosthesis designs or bone preparation is still unclear. While the benefit of using tranexamic acid (TXA) is well demonstrated, our study aims to determine the effect of different knee prosthesis designs uses and efficacy of blood loss reduction by different routes of TXA administration.

Methods: The 228 patients undergone primary TKA were randomized to determine between open-box and closed-box prosthesis.

Intra-Articular Tranexamic Acid Mitigates Blood Loss and Morphine Use After Total Knee Arthroplasty. A Randomized Controlled Trial.

Background: Tranexamic acid (TXA) has been widely used in total knee arthroplasty (TKA) for blood loss reduction. Given limited evidence on potential relationship between the TXA and improvement of pain control and functional outcome after TKA, this study aimed at comparing the blood loss, pain scores, morphine consumption, and knee flexion across the TXA administration routes.

Methods: The 228 primary TKA were randomized into no TXA use (No-TXA), intra-articular TXA (15 mg/kg) use (IA-TXA), and intravenous TXA (10 mg/kg) use (IV-TXA).

Anterior vs Posterior Periarticular Multimodal Drug Injections: A Randomized, Controlled Trial in Simultaneous Bilateral Total Knee Arthroplasty.

Background: Currently, various techniques are used to overcome postoperative pain after total knee arthroplasty. A local analgesic infiltration with periarticular multimodal drug injection (PMDI) is favorable because of its simplicity, safety, and efficacy. The present study compared the efficacy of a PMDI at the anterior vs posterior compartments.

Result of arthroscopic removal of an enchondroma at the talar dome: a case report.

Enchondroma is a benign tumor that is generally asymptomatic and rarely found in the talus. A forty-nine-year-old man, had a chronic left ankle pain which related to moderate to heavy activity. A plain radiograph and magnetic resonance imaging (MRI) revealed a 1.

Randomized controlled trial local injection for treatment of lateral epicondylitis, 5 and 10 mg triamcinolone compared.

Objective: To compare the efficacy and adverse effects between 5 and 10 mg triamcinolone local injection for treatment of the lateral epicondylitis. The primary outcome was the improvement of pain after 12 weeks of treatment. The secondary outcome was the adverse effects rate.
