The efficacy and safety of opening-wedge high tibial osteotomy in treating unicompartmental knee osteoarthritis: Protocol for a systematic review and meta-analysis.

Medicine (Baltimore) 2019 Mar;98(12):e14927

The Second People's Hospital of Foshan (Affiliated Foshan Hospital of Southern Medical University), Foshan.

Background: High tibial osteotomy (HTO) is an effective surgical technique that can stop or inhibit the progression of unicompartmental knee osteoarthritis (KOA) to avoid or postpone the need for knee arthroplasty in patients. Whether opening-wedge high tibial osteotomy (OWHTO) is superior to closing-wedge high tibial osteotomy (CWHTO) in treating unicompartmental KOA remains controversial.

Methods: Databases (Cochrane Library, EMBASE, and PubMed) were searched from their establishment to July 1, 2018 for randomized controlled trials comparing the application of OWHTO to CWHTO in patients with unicompartmental KOA. Read More

Randomized clinical trial of medial unicompartmentel versus total knee arthroplasty for anteromedial tibio-femoral osteoarthritis. The study-protocol.

BMC Musculoskelet Disord 2019 Mar 20;20(1):119. Epub 2019 Mar 20.

Department of Orthopedic Surgery, Gentofte Hospital, Kildegårdsvej 28, DK-2900, Hellerup, Denmark.

Background: In treatment of isolated medial unicondylar osteoarthritis of the knee, it is possible to choose between medial unicondylar knee arthroplasty (mUKA), or a total knee prosthesis (TKA). The demand for a blinded multicenter RCT with the comparison of mUKA and TKA has been increasing in recent years, to determine which prosthesis is better. Supporters of TKA suggest this treatment gives a more predictable and better result, whereas supporters of UKA suggest it is unnecessary to remove functional cartilage in other compartments.

Perioperative medical management for patients with RA, SPA, and SLE undergoing total hip and total knee replacement: a narrative review.

BMC Rheumatol 2018 30;2. Epub 2018 Jan 30.

Department of Medicine, Weill Cornell Medical School, Division of Rheumatology Hospital for Special Surgery, 535 E 70th St, New York City, NY 10021 USA.

Total hip (THA) and total knee arthroplasty (TKA) are widely used, successful procedures for symptomatic end stage arthritis of the hips or knees, but patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and spondyloarthritis (SPA) including ankylosing spondylitis (AS) and psoriatic arthritis (PSA) are at higher risk for adverse events after surgery. Utilization rates of THA and TKA remain high for patients with RA, and rates of arthroplasty have increased for patients with SLE and SPA. However, complications such as infection are increased for patients with SLE, RA, and SPA, most of whom are receiving potent immunosuppressant medications and glucocorticoids at the time of surgery.

The contralateral knee may not be a valid control for biomechanical outcomes after unilateral total knee arthroplasty.

Gait Posture 2019 Mar 8;70:179-184. Epub 2019 Mar 8.

Rutgers, The State University of New Jersey, School of Health Professions, Department of Rehabilitation and Movement Sciences, Physical Therapy Program North, 65 Bergen Street - Office 714A, Newark, NJ, 07107, USA.

Background: Although unilateral symptoms and unilateral total knee arthroplasty (TKA) are common, many patients have bilateral radiographic osteoarthritis (OA). Because the contralateral (non-operated) limb is often used as a comparison for clinical and biomechanical outcomes, it is important to know if the presence of OA influences movement patterns in either limb.

Research Question: The purpose of this study was to compare bilateral sagittal plane biomechanics between subjects with and without contralateral knee OA after unilateral TKA. 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

Department of Orthopedics, Icahn School of Medicine at Mount Sinai, New York, NY.

Background: With the advent of mandatory bundle payments for total joint arthroplasty (TJA), assessing patients' risk for increased 90-day complications and resource utilization is crucial. This study assesses the degree to which preoperative patient-reported outcomes predict 90-day complications, episode costs, and utilization in TJA patients.

Methods: All TJA cases in 2017 at 2 high-volume hospitals were queried. Read More

A prospective randomized open-label study of single injection versus continuous adductor canal block for postoperative analgesia after total knee arthroplasty.

Bone Joint J 2019 Mar;101-B(3):340-347

Department of Orthopedic Surgery, University of Pennsylvania, Philadelphia, Pennsylvania, USA.

Aims: Adductor canal block (ACB) has emerged as an alternative to femoral nerve block (FNB) for analgesia after total knee arthroplasty (TKA). The optimal duration of maintenance of the ACB is still questionable. The purpose of this study was to compare the analgesic benefits and physiotherapy (PT) outcomes of single-shot ACB to two different regimens of infusion of the continuous ACB, 24-hour and 48-hour infusion.

Medial and lateral gap laxity differential in computer-assisted kinematic total knee arthroplasty.

Bone Joint J 2019 Mar;101-B(3):331-339

Sport and Exercise Science, College of Healthcare Sciences, Division of Tropical Health & Medicine, James Cook University, Townsville, Australia.

Aims: The results of kinematic total knee arthroplasty (KTKA) have been reported in terms of limb and component alignment parameters but not in terms of gap laxities and differentials. In kinematic alignment (KA), balance should reflect the asymmetrical balance of the normal knee, not the classic rectangular flexion and extension gaps sought with gap-balanced mechanical axis total knee arthroplasty (MATKA). This paper aims to address the following questions: 1) what factors determine coronal joint congruence as measured on standing radiographs?; 2) is flexion gap asymmetry produced with KA?; 3) does lateral flexion gap laxity affect outcomes?; 4) is lateral flexion gap laxity associated with lateral extension gap laxity?; and 5) can consistent ligament balance be produced without releases?

Patients And Methods: A total of 192 KTKAs completed by a single surgeon using a computer-assisted technique were followed for a mean of 3. Read More

What Is the Risk of Repeat Revision When Patellofemoral Replacement Is Revised to TKA? An Analysis of 482 Cases From a Large National Arthroplasty Registry.

Clin Orthop Relat Res 2018 Oct 30. Epub 2018 Oct 30.

P. L. Lewis, S. E. Graves, Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR), Adelaide, South Australia, Australia P. L. Lewis, Wakefield Orthopaedic Clinic, Adelaide, South Australia, Australia A. Cuthbert, South Australian Health and Medical Research Institute (SAHMRI), Adelaide, South Australia D. Parker, Sydney Orthopaedic Research Institute, Chatswood, New South Wales, Australia P. Myers, Brisbane Orthopaedic & Sports Medicine Centre, Spring Hill, Queensland, Australia.

Background: Patellofemoral replacements (PFRs) have a higher rate of revision than unicompartmental knee arthroplasty or TKA. However, there is little information regarding why PFRs are revised, the components used for these revisions, or the outcome of the revision procedure. Some contend that PFR is a bridging procedure that can easily be revised to a TKA with similar results as a primary TKA; however, others dispute this suggestion. Read More

Association of Overlapping Surgery With Perioperative Outcomes.

JAMA 2019 02;321(8):762-772

Department of Health Care Policy, Harvard Medical School, Boston, Massachusetts.

Importance: Overlapping surgery, in which more than 1 procedure performed by the same primary surgeon is scheduled so the start time of one procedure overlaps with the end time of another, is of concern because of potential adverse outcomes.

Objective: To determine the association between overlapping surgery and mortality, complications, and length of surgery.

Design, Setting, And Participants: Retrospective cohort study of 66 430 operations in patients aged 18 to 90 years undergoing total knee or hip arthroplasty; spine surgery; coronary artery bypass graft (CABG) surgery; and craniotomy at 8 centers between January 1, 2010, and May 31, 2018. Read More

Computer navigation has no beneficial effect on blood loss and transfusion in sequential bilateral total knee Arthroplasty.

J Orthop Surg (Hong Kong) 2019 Jan-Apr;27(1):2309499019832440

2 Consultant Anaesthesia, Fortis Escorts Hospital, Jaipur, Rajasthan, India.

Background:: Bilateral total knee arthroplasty is associated with significant blood loss. Postoperative anaemia retards patients recovery, and blood transfusion increases the risk for major complications including infection. While strategies like hypotensive anaesthesia, tranexamic acid, bone wax and so on are useful to conserve blood, navigation has also shown to decrease blood loss and transfusion in unilateral knee arthroplasty.

Perioperative Dietary Restriction of Carbohydrates in the Management of Blood Glucose Levels in Patients Undergoing Total Knee Replacement.

J Arthroplasty 2019 Jan 29. Epub 2019 Jan 29.

Department of Orthopaedic Surgery, Brigham and Women's Hospital, Boston, MA; Department of Orthopaedic Surgery, Harvard Medical School, Boston, MA.

Background: Approximately 75% of the US population over 65 years has prediabetes or diabetes. Despite current evidence for the efficacy of carbohydrate restriction in managing blood glucose, this practice has not been implemented as part of routine perioperative blood sugar management. We hypothesize that a carbohydrate reduced hospital diet (CRD) of 135 g/d may improve blood sugar levels following total knee arthroplasty (TKA) compared to a non-carbohydrate reduced hospital diet (NCRD).
