3D-multi-spectral T mapping near metal implants.

Magn Reson Med 2019 Mar 18. Epub 2019 Mar 18.

Radiology, Medical College of Wisconsin, Milwaukee, Wisconsin.

Purpose: Due to host-mediated adverse reaction to metallic debris, there is an increasing need for noninvasive assessment of the soft tissue surrounding large joint arthroplasties. Quantitative mapping can be beneficial for tissue characterization and early diagnosis of tissue pathology but current mapping techniques lack the capability to image near metal hardware. A novel multi-spectral mapping technique is proposed to address this unmet need. Read More

Prosthetic joint infection: A major threat to successful total joint arthroplasty.

Indian J Med Microbiol 2018 Oct-Dec;36(4):475-487

Department of Microbiology, All India Institute of Medical Sciences, New Delhi, India.

Total joint arthroplasty (TJA) is one of the most common and reliable orthopaedic procedures that has significantly improved the quality of life of patients with degenerative joint diseases. Following the increase in the ageing population, availability of trained orthopaedic surgeons and advances in implantation procedures, demand for TJA both globally and in India is significantly increasing. Though TJA is one of the most cost-successful orthopaedic procedures, prosthetic joint infection (PJI) is one of the major complications of joint arthroplasty. Read More

Principal component analysis as a tool for determining optimal tibial baseplate geometry in modern TKA design.

Acta Orthop Belg 2018 Dec;84(4):452-460

Optimal tibial component fixation in total knee arthroplasty (TKA) requires maximal tibial bone coverage, optimized mediolateral cortical fit as well as component rotation. Failure to achieve an optimal fit may result in component subsidence and loosening in case of undersizing, or overhang with subsequent soft tissue impingement in case of overhang. To date there is no consensus on optimal tibial component shape, and significant variability exists among different design manufacturers. Read More

A Novel Mobile Phone Text Messaging Platform Improves Collection of Patient-Reported Post-operative Pain and Opioid Use Following Orthopedic Surgery.

HSS J 2019 Feb 22;15(1):37-41. Epub 2018 Oct 22.

Hospital for Special Surgery, 535 East 70th Street, New York, NY 10021 USA.

Background: Prospective collection of patient-reported opioid consumption and pain levels post-surgically may hold value in highlighting solutions related to the opioid crisis. Traditional methods for collecting patient-reported outcomes after surgery, such as paper surveys, often have poor response rates, and electronic messaging may offer more convenience and therefore yield more robust data.

Questions/purposes: The purpose of this study was to evaluate whether a novel mobile phone short message service (SMS) platform would lead to better patient response rates to surveys on pain and opioid use than data-collection tools. Read More

Institutional Guidelines Can Decrease the Amount of Opioids Prescribed After Total Joint Replacement.

HSS J 2019 Feb 1;15(1):27-30. Epub 2018 Oct 1.

Department of Orthopaedic Surgery, Hospital for Special Surgery, 535 E. 70th Street, New York, NY 10021 USA.

Background: In the midst of the nationwide opioid epidemic, our institution began an effort to improve the education of opioid prescribers and disseminate procedure-specific guidelines for the number of opioid pills to prescribe post-operatively for total joint arthroplasty. The number of opioid pills suggested for total hip or knee replacement was 70 tablets.

Questions/purposes: We sought to evaluate the impact of the new institutional guideline on opioid prescribing practices, hypothesizing that it would lead to a decrease in the number of pills prescribed but an increase in patient call volume after discharge. Read More

The Use of Stems for Morbid Obesity in Total Knee Arthroplasty.

J Knee Surg 2019 Mar 12. Epub 2019 Mar 12.

Department of Orthopaedics, Stanford University, Redwood City, California.

Morbidly obese patients undergoing total knee arthroplasty have worse functional outcomes and implant survival, and increased revision rates compared with nonobese patients. In addition to increased medical comorbidities and difficult exposure, increased stress on the tibial implant and altered kinematics of knee motion contribute to aseptic loosening and medial collapse. Increased implant fixation, including use of a stemmed tibial implant, may be a way to help avoid these complications. Read More

Are Joint Surgeons Being Adequately Compensated for Single-Component versus Double-Component Revision TKA? An Analysis of Relative Value Units.

J Knee Surg 2019 Mar 12. Epub 2019 Mar 12.

Department of Orthopaedics, The Ohio State University Wexner Medical Center, Columbus, Ohio.

Relative value units (RVUs) are used for ensuring that physicians are appropriately reimbursed based on case complexity. While past research has elucidated that surgeons are reimbursed at a higher rate for primary total knee arthroplasty (TKA) versus revision TKA, no study has explored differences in reimbursements between single-component and double-component revisions, considering a double-component revision is likely to require more effort/skill as compared with single-component revision. The 2015 to 2016 American College of Surgeons National Surgical Quality Improvement Program files were queried using Current Procedural Terminology (CPT) codes for single-component revision TKA (CPT-27486) and double-component revision TKA (CPT-27487).

Pes Anserine Tendon Injury Resulting from Cooled Radiofrequency Ablation of the Inferior Medial Genicular Nerve.

PM R 2019 Mar 12. Epub 2019 Mar 12.

Department of Physical Medicine and Rehabilitation, University of Utah, Salt Lake City, UT.

Early evidence from clinical trials suggests effectiveness of fluoroscopically guided genicular nerve radiofrequency ablation (RFA) for the treatment of chronic knee pain due to osteoarthritis. One small sham-controlled study has demonstrated efficacy of this procedure. Additionally, there is interest in the use of genicular RFA for the treatment of persistent chronic knee pain post-total knee arthroplasty, though efficacy has yet to be demonstrated. Read More

Mediolateral coronal laxity does not correlate with knee range of motion after total knee arthroplasty.

Arch Orthop Trauma Surg 2019 Mar 11. Epub 2019 Mar 11.

Niigata University Crisis Management Office, Niigata University Hospital, Niigata University Graduate School of Medical and Dental Sciences, 1 Asahimachi Dori, Niigata, Niigata, 951-8520, Japan.

Introduction: It remains controversial whether coronal laxity after total knee arthroplasty (TKA) is a critical factor in determining clinical outcomes such as knee range of motion (ROM). The purpose of this study was to evaluate the correlation between postoperative ROM and coronal laxity, which was defined as the angular motion from the neutral, unloaded position to the loaded position, in patients with medial knee osteoarthritis undergoing TKA.

Materials And Methods: Preoperative and 1-year postoperative coronal laxity were assessed using radiographs by applying a force of 150 N with an arthrometer. Read More

Preoperative balloon pulmonary angioplasty enabled noncardiac surgery of a patient with chronic thromboembolic pulmonary hypertension (CTEPH): A case report.

Medicine (Baltimore) 2019 Mar;98(10):e14807

Department of Anesthesiology, Faculty of Medicine, The University of Tokyo, Tokyo.

Rationale: Chronic thromboembolic pulmonary hypertension (CTEPH) is a disease with a poor prognosis, characterized by chronic thromboembolic obstruction of the pulmonary arteries and pulmonary hypertension. Balloon pulmonary angioplasty (BPA) is a newly emergent treatment for CTEPH, which may substitute pulmonary endarterectomy, the standard but more invasive treatment for CTEPH. Here, we report the case of a CTEPH patient who underwent 2 noncardiac surgeries without complications after preoperative intervention of BPA. Read More
