Longitudinal changes in shoulder arthroplasty stratified by age groups, types of surgical facilities, and geographical regions in Korea from 2010 to 2020.

Background: Shoulder arthroplasty (SA), including hemiarthroplasty, reverse and anatomical total SA (TSA), improves quality of life by reducing shoulder pain and restoring function in patients not only with irreparable rotator cuff tears and/or cuff tear arthropathy but also with osteoarthritis posttraumatic arthritis, proximal humeral fractures, etc. Given the rapid developments in artificial joints and improvements in postoperative outcomes, the number of SA surgeries is increasing worldwide. Therefore, we investigated changes in trends over time in Korea.

Transfusion Trends of Knee Arthroplasty in Korea: A Nationwide Study Using the Korean National Health Insurance Service Sample Data.

Knee arthroplasties are strongly associated with blood transfusion to compensate for perioperative bleeding. The purpose of this study was to evaluate trends of transfusion associated with knee arthroplasties using nationwide data of the National Health Insurance Service-National Sample Cohort (NHIS-NSC). Using data from the nationwide claims database of the Health Insurance Review Assessment Service managed by the NHIS, 50,553 knee arthroplasties under three categories (total knee replacement arthroplasty, uni-knee replacement arthroplasty, and revision arthroplasty) from 2012 to 2018 were identified.

Trends of Total Knee Arthroplasty According to Age Structural Changes in Korea from 2011 to 2018.

Total Knee Arthroplasty (TKA) is one of the most commonly performed surgeries worldwide since it can improve pain, quality of life, and functional outcome. Due to the expansion of hospitals specialized in joint surgery, the topography of TKA implementation in Korea is changing. This study analyzed longitudinal trends of TKA based on changes in age distribution, sex, hospital, and region based on the Health Insurance Review and Assessment Service (HIRA) of Korea database.

A technique for repairing rotator cuff transtendinous tears with a remnant attached to the footprint.

Background: Some unusual rotator cuff (RC) tears are located in more proximal tendinous portions, with substantial remnant tissue attached to the footprint. The two options for surgical repair are sacrificing or preserving the remnant tissue. We introduce a surgical repair technique that preserves as much of the remnant footprint as possible.

Staged patellar tendon reconstruction using doubled bone-patellar tendon-bone allograft for infected patellar tendon rupture: a rare case report of three years follow-up.

Background: Patellar tendon rupture is a relatively rare injury that usually requires surgical treatment. The optimal therapeutic strategy is still controversial, especially when either concomitant patellar tendon infection or soft tissue infection surrounds the patellar tendon. Until recently, most reported reconstruction methods are extensive and difficult to apply because of the poor condition of the soft tissue surrounding the patellar tendon.

Arthroscopic treatment of Mycobacterium massiliense septic arthritis outbreak after intra-articular injection: A case-series report and literature review.

Non-tuberculous mycobacteria (NTM) comprise mycobacteria, with the exceptions of Mycobacterium (M.) leprae and the M. tuberculosis complex.

Diagnosis and treatment of bullous pemphigoid that developed twice after total knee replacement arthroplasty: a case report.

Background: Total knee replacement arthroplasty (TKA) is frequently performed in South Korea. Simple swelling-associated blistering around the periphery of the operative wound is a well-known adverse effect. However, in rare cases, the blisters are bullous pemphigoid (BP).

Outcome Differences of Remnant- Preserving versus Non-Preserving Methods in Arthroscopic Anterior Cruciate Ligament Reconstruction: A Meta-analysis with Subgroup analysis.

Purpose: To analyze differences in clinical outcomes of arthroscopic anterior cruciate ligament reconstruction between remnant-preserving and non-preserving methods.

Methods: International electronical databases PubMed, Embase, and the Cochrane central database from January 1966 to December 2017 were searched for randomized controlled trials (RCTs) and observational studies that compared differences of clinical outcomes of ACL reconstruction with and without remnant preservation. A meta-analysis of these studies was performed to compare clinical outcomes.

Survivorship and Complications after Hip Fracture Surgery in Patients with Chronic Kidney Disease.

The aim of this study was to investigate survival rate, complications and associated risk factors after hip fracture surgery in patients with chronic kidney disease (CKD) by comparing to non-CKD patients. A total of 119 patients (130 hips, 63 hips CKD group, 67 hips non-CKD) who underwent hip fracture surgery were included. We assessed variables including age, gender, CKD, comorbidities, operation delay and operation time as risk factors for survival and complications after hip fracture surgery.

Revision Arthroplasty Using a MUTARS® Prosthesis in Comminuted Periprosthetic Fracture of the Distal Femur.

Periprosthetic fractures after total knee arthroplasty (TKA) are gradually increasing, reflecting extended lifespan, osteoporosis, and the increasing proportion of the elderly during the past decade. Supracondylar periprosthetic femoral fracture is a potential complication after TKA. Generally, open reduction and internal fixation are the conventional option for periprosthetic fracture after TKA.

A protocol avoiding allogeneic transfusion in joint arthroplasties.

Introduction: Arthroplasties of hip and knee are associated with blood loss, which may lead to adverse patient outcome. Performing arthroplasties in Jehovah's Witness patients who do not accept transfusion has been a matter of concern. We developed a protocol, which avoids transfusion in arthroplasties of Jehovah's Witness patients, and evaluated the feasibility and safety of the protocol.

Anatomic Single-Bundle Anterior Cruciate Ligament Reconstruction With Remnant Preservation Using Outside-In Technique.

This report describes a modified anatomic single-bundle anterior cruciate ligament (ACL) reconstruction technique using the FlipCutter guide pin (Arthrex, Naples, FL) as a retrograde drill and a cortical suspensory fixation device (TightRope; Arthrex) with an adjustable graft loop length. Preservation of the ACL remnant as a biological sleeve for the graft is an important issue from the viewpoints of acceleration of revascularization and ligamentization, preservation of the proprioceptive nerve fibers, enhancement of the biological environment for healing, and maintenance of the anchor point at the native tibial attachment, in addition to yielding a lower incidence of tibial bone tunnel enlargement. The goal of our technique is to obtain some advantages of the remnant-preserving technique through an anatomic single-bundle ACL reconstruction, which is performed to minimize damage to the ACL tibial remnant.

Arthroscopic one-piece reshaping for symptomatic discoid medial meniscus with anomalous amalgamating into anterior cruciate ligament.

Discoid shapes of lateral menisci are relatively common finding, whereas discoid medial menisci are less common. Discoid medial meniscus with associated anomalous variants has been reported. However, symptomatic complex tear of complete type discoid medial meniscus with anomalous blending with anterior cruciate ligament is an extremely rare pathology.

Clinical and Radiologic Outcomes among Bipolar Hemiarthroplasty, Compression Hip Screw and Proximal Femur Nail Antirotation in Treating Comminuted Intertrochanteric Fractures.

Purpose: In comminuted intertrochanteric fractures, various operative options have been introduced. The purpose of this study was to determine whether there were differences in clinical and radiologic outcomes among bipolar hemiarthroplasty (BH), compression hip screw (CHS) and proximal femur nail antirotation (PFNA) in treating comminuted intertrochanteric fractures (AO/OTA classification, A2 [22, 23]).

Materials And Methods: We retrospectively evaluated total 150 patients (BH, 50; CHS, 50; PFNA, 50) who were operated due to intertrochanteric fractures from March 2010 to December 2012 and were older than 65 years at the time of surgery.

Posterior shoulder dislocation with ipsilateral proximal humerus type 2 physeal fracture: case report.

In pediatric patients, proximal humeral physeal fractures are uncommon injuries compared with distal physeal fractures. Usually, the growth plate is the most vulnerable site of fracture in the proximal humerus. Proximal humeral physeal fractures accompanying posterior shoulder dislocation are very rare.

Risk factors for postoperative ileus following orthopedic surgery: the role of chronic constipation.

Background/aims: Distinction is vague between severe constipation and postoperative ileus (POI) in terms of pathogenesis, clinical features, and treatment options. However, no data are available regarding their associations.

Methods: After retrospective review of data from patients who underwent orthopedic surgery during the first 6 months of 2011, a total of 612 patients were included.

A pulled sutures technique for bony Bankart lesion.

In an attempt to present a new surgical technique for arthroscopic bony Bankart fixation, the authors developed the pulled sutures technique. In executing the new method, the authors first passed several non-absorbable sutures through labroligamentous tissue with displaced articular fragment by mimicking transglenoid suture technique. Aimed at achieving a safe and stable fixation, using a knotless anchor rather than transglenoid suture, was deployed.

Immunohistochemical study of mechanoreceptors in the tibial remnant of the ruptured anterior cruciate ligament in human knees.

This study was performed to identify the mechanoreceptors in the tibial remnants of ruptured human anterior cruciate ligaments (ACL) by immunohistochemical staining. Thirty-six specimens of tibial ACL remnants were obtained from patients with ACL ruptures during arthroscopic ACL reconstruction. As control, two normal ACL specimens were taken from healthy knee amputated at thigh level due to trauma.

Comparison of clinical results according to amount of preserved remnant in arthroscopic anterior cruciate ligament reconstruction using quadrupled hamstring graft.

Purpose: The purpose of this study was to analyze the clinical results of anterior cruciate ligament (ACL) reconstruction with the remnant-preserving technique by use of a hamstring graft and looped sutures according to the amount of the tibial remnant of the ACL.

Methods: Sixteen subjects had undergone ACL reconstruction with the remnant-preserving technique by use of 4 strands of a hamstring tendon and a looped suture technique and were followed up for at least 12 months. The mean follow-up was 35.

Arthroscopic anterior cruciate ligament reconstruction with the tibial-remnant preserving technique using a hamstring graft.

We propose that the tibial remnant of the anterior cruciate ligament (ACL) is able to enhance the revascularization and cellular proliferation of the graft, to preserve proprioceptive function, and to be able to acquire anatomic placement of the graft without roof impingement. Therefore, it seems reasonable to assume that preserving the tibial remnant as much as possible as a source of reinnervation, if technically possible without causing impingement, would be of potential benefit to the patient. Our surgical technique was developed to maximize the preservation of the tibial remnant.

Arthroscopic retrieval of a very rare penetrating foreign body of the knee.

We report the very rare case of an 8-year-old boy who accidentally fell on the ground, causing the lead of a pencil to penetrate his left knee joint cavity. After radiographic diagnosis, the pencil was removed by a physician at a private clinic and the boy was referred to our department for further evaluation. We performed arthroscopic retrieval of the pencil lead through standard arthroscopic portals without an accessory portal.
