Total Elbow Arthroplasty: Clinical Outcomes, Complications, and Revision Surgery.
Authors: Kwak JM, Koh KH, Jeon IH Abstract Total elbow arthroplasty is a common surgical procedure used in the management of advanced rheumatoid arthritis, posttraumatic arthritis, osteoarthritis, and unfixable fracture in elderly patients. Total elbow prostheses have evolved over the years and now include the linked, unlinked, and convertible types. However, long-term complications, including infection, aseptic loosening, instability, and periprosthetic fracture, remain a challenge. Here, we introduce each type of implant and evaluate clinical outcomes and complications by reviewing the previous literature. PM...

Metabolic and Hemodynamic Results and Early Complications in Simultaneous Bilateral versus Unilateral Hip Arthroscopy.
Conclusions: The variations of hemodynamic parameters in patients undergoing hip arthroscopy remained within normal ranges. The findings of this study suggest that bilateral hip arthroscopy be selected according to the patient's condition, considering that the risk of complications and metabolic alterations in bilateral hip arthroplasty are similar to those in unilateral arthroscopy.

Outcomes of Fast-Track Multidisciplinary Care of Hip Fractures in Veterans: A Geriatric Hip Fracture Program Report.
Conclusions: Elderly hip fracture has a high risk of mortality (14%-58%). Thus, expeditious surgery within 24 hours of admission has been advocated in the Western literature to minimize mortality. Mortality rate at 1 year after surgery remains at 10% to 24%. In our study, even with aggressive co-management, the average delay to hip fracture fixation was more than 3 days; however, the 1-year mortality was relatively low (7.7%). This indicates the importance of preoperative optimization and postoperative rehabilitation for independent ambulation and mortality reduction in the elderly population. PMID: 31788160 [PubMed - ...

Anterior Cortical Window Technique Instead of Extended Trochanteric Osteotomy in Revision Total Hip Arthroplasty: A Minimum 10-Year Follow-up.
Conclusions: With use of an anterior cortical window, a well-fixed stem can be easily removed, and a new stem can be inserted with firm mediolateral stability in the proximal femur in revision THA. We recommend using this technique instead of the extended trochanteric osteotomy in revision THA. PMID: 31788161 [PubMed - in process] (Source: Clinics in Orthopedic Surgery)

Follow-up of Metal-on-Metal Hip Replacements at a Large District Hospital and the Implementation of Medicines and Healthcare Products Regulatory Agency Guidelines: A Review of 297 Patients.
Conclusions: Positive MARS-MRI can often occur in the absence of elevated metal ion levels; elevated blood metal ion levels do not mean MARS-MRI will be positive. All patients with MoM replacements were at risk. It is imperative to assess patients regularly for symptoms that may raise clinical suspicion and maintain a low threshold to performing MARS-MRI.

The Effect of Prosthesis Design on Blood Loss in Simultaneous Bilateral Total Knee Arthroplasty: Closed-Box versus Open-Box Prosthesis.
Authors: Rattanaprichavej P, Laoruengthana A, Rasamimogkol S, Varakornpipat P, Reosanguanwong K, Pongpirul K Abstract Background: Various pre- and perioperative risk factors have been reported in association with blood loss in knee arthroplasty. However, the effect of the uncovered cancellous surface on blood loss in simultaneous bilateral total knee arthroplasty (SBTKA) by different prosthetic designs is not well elucidated. Therefore, this study aimed to compare the blood loss and transfusion rate between different knee prostheses in SBTKA and to identify risk factors that influence blood loss and transfusion aft...

Influence of Patellar Tilt Angle in Merchant View on Postoperative Range of Motion in Posterior Cruciate Ligament-Substituting Fixed-Bearing Total Knee Arthroplasty.

Methods: In this prospective cohort study, we followed up 169 patients for at least 2 years after TKA using PS fixed-bearing prosthesis. The patients were divided into two groups according to the flexion gap value-calculated by subtracting the thickness of the final bearing from th...

Alpha Angle as a Predictor of Impending Contralateral Slipped Capital Femoral Epiphysis in an Asian Population.
Authors: Chan CX, Yang YO, Cheng GHM, Gera SK, Mohammad ABZ Abstract Background: Prophylactic pinning of the uninvolved side after unilateral slipped capital femoral epiphysis (SCFE) is controversial. The alpha angle, a measurement of femoral head-neck aspherity, was proposed as a predictor of progression of contralateral SCFE with a treatment threshold of greater than 50.5°. The aim of this study was to evaluate its validity in our cohort of patients. Methods: A retrospective review of a 10-year series of patients who presented with unilateral SCFE was conducted.

A Modified Under-Vastus Approach for Knee Arthroplasty with Anatomical Repair of Soft Tissue.
Authors: Hiranaka T, Tanaka T, Fujishiro T, Anjiki K, Nagata N, Kitazawa D, Kotoura K, Okamoto K Abstract The under-vastus approach (UVA) is a modification of the conventional subvastus approach for knee arthroplasty. Our modified UVA allows the muscles to be spared while offering good exposure of the operative field and facilitating anatomical repair of the capsule and fascia. A medial parapatellar incision is made and the vastus medialis fascia is incised along the same line. The muscle belly is not incised but detached from the surrounding fascia and retracted laterally. The suprapatellar pouch capsule is then l...

Treatment Strategy for Frozen Shoulder.
Authors: Cho CH, Bae KC, Kim DH Abstract Frozen shoulder (FS) is a common shoulder disorder characterized by a gradual increase of pain of spontaneous onset and limitation in range of motion of the glenohumeral joint. The pathophysiology of FS is relatively well understood as a pathological process of synovial inflammation followed by capsular fibrosis, but the cause of FS is still unknown. Treatment modalities for FS include medication, local steroid injection, physiotherapy, hydrodistension, manipulation under anesthesia, arthroscopic capsular release, and open capsular release. Conservative management leads to i...

Preoperative Iron Supplementation and Restrictive Transfusion Strategy in Hip Fracture Surgery.
Authors: Yoon BH, Lee BS, Won H, Kim HK, Lee YK, Koo KH Abstract Background: Hip fracture surgery (HFS) is often associated with perioperative blood loss, and it frequently necessitates transfusion. However, the hemoglobin (Hb) threshold for transfusion remains controversial in hip fracture patients. We evaluated the usefulness of the restrictive strategy and preoperative intravenous iron supplementation in HFS. Methods: We retrospectively reviewed the medical records of 1,634 patients (> 60 years of age) who underwent HFS between May 2003 and June 2014 and were followed up for 1 year or more after surgery. ...

What to Know for Selecting Cruciate-Retaining or Posterior-Stabilized Total Knee Arthroplasty.
Authors: Song SJ, Park CH, Bae DK Abstract There has been continuing debate about the superiority of cruciate-retaining (CR) total knee arthroplasty (TKA) versus posterior-stabilized (PS) TKA for obtaining knee joint stability with functional improvement. Many surgeons tend to select the type of prosthesis on the basis of their own training and experience. However, the selection must be based on a great store of knowledge rather than on the surgeon's preconceptions or preferences. CR TKA may not be feasible in certain settings: posterior cruciate ligament insufficiency, severe deformity, and history of trauma or su...

Spinal Navigation during Orthopedic Residency Training: A Double-Edged Sword?
Conclusions: All selected residents were perceived to be competent to apply pedicle screws using spinal navigation. However, some of them were not able to identify the entry points correctly, probably due to overreliance on spinal navigation. Therefore, we encourage residents to concentrate on surface anatomy and tactile feedback rather than completely relying on the navigation display monitor during every screw placement. In addition, incorporating cadaveric and saw bone workshops as a part of teaching program can enhance better understanding of surgical anatomy.
