Three-phase Technetium-99m bone scanning in patients with pain in the knee region after cemented total knee arthroplasty.

Eur J Orthop Surg Traumatol 2019 Mar 19. Epub 2019 Mar 19.

Princess Elizabeth Orthopaedic Centre, Royal Devon and Exeter Foundation Trust, Barrack Road, Exeter, EX2 5DW, UK.

Introduction: Our aim was to question the usefulness of a three-phase bone scan in the evaluation of pain in the knee region after TKR. Our hypothesis was that an abnormal investigation had a poor association with the presence of infection or loosening, and did not provide any additional diagnostic information above that already available through other standard investigations.

Methods: A retrospective study over a 24-month period was performed comprising 118 patients investigated with a TPBS. Read More

Ultrasound measurement of knee synovial fluid during external pneumatic compression.

J Orthop Res 2019 Jan 15. Epub 2019 Jan 15.

Department of Medicine Rheumatology, Division National Jewish Health, Denver, Colorado.

Synovial fluid based biomarker research has been limited by the small volumes of synovial fluid from the knees of some patients. We used ultrasound (US) to determine if synovial fluid could be displaced into an access port during pneumatic compression to 100 mmHg. Forty knees from 37 consecutive arthritis patients with rheumatoid arthritis -25, osteoarthritis -8, psoriatic arthritis -2, and 1 each with systemic lupus erythematosus and gout were evaluated.

[Systemic lupus erythematosus with acquired hemophilia A: a case report].

Authors:
F Yang Y S Zhou Y Jia

Beijing Da Xue Xue Bao Yi Xue Ban 2018 Dec;50(6):1108-1111

Department of Rheumatology and Immunology, Peking University People's Hospital, Beijing 100044, China.

Acquired hemophilia A (AHA) is anunusual disease resulting from autoantibodies (inhibitors) against coagulation factor VIII (FVIII) and clinically manifests as bleeding, which sometimes can cause potentially limb-threatening or life-threatening situations. AHA is associated with cancers, auto-immune disorders, infections, dermatologic conditions and certain medications, among which it is commonly secondary to multiple rheumatologic conditions, such as rheumatoid arthritis, systemic lupus erythematosus (SLE), pollymyositis, autoimmune hemolytic anemia and undifferentiated connective tissue disease. In autoimmune diseases, it may be the result of autoantibody producing against FVIII, and some cases of AHA may act as the first manifestation of SLE. Read More

In vitro and in vivo potentialities for cartilage repair from human advanced knee osteoarthritis synovial fluid-derived mesenchymal stem cells.

Stem Cell Res Ther 2018 11 28;9(1):329. Epub 2018 Nov 28.

UMR 7365 CNRS-UL, IMoPA (Ingénierie Moléculaire et Physiopathologie Articulaire), Biopôle de l'Université de Lorraine, Campus Brabois-Santé, 9 Avenue de la Forêt de Haye, BP 20199, 54505, Vandœuvre-Lès-Nancy, France.

Background: Mesenchymal stem cells (MSCs) are found in synovial fluid (SF) and can easily be harvested during arthrocentesis or arthroscopy. However, SF-MSC characterization and chondrogenicity in collagen sponges have been poorly documented as well as their hypothetical in vivo chondroprotective properties with intra-articular injections during experimental osteoarthritis (OA).

Methods: SF-MSCs were isolated from human SF aspirates in patients suffering from advanced OA undergoing total knee joint replacements. Read More

Suspected periprosthetic joint infection after total knee arthroplasty under propofol versus sevoflurane anesthesia: a retrospective cohort study.

Can J Anaesth 2018 Aug 23;65(8):893-900. Epub 2018 Apr 23.

Department of Public Health, Health Management and Policy, Nara Medical University, 840, Shijo-cho, Kashihara, Nara, 634-8521, Japan.

Purpose: Periprosthetic joint infection is a serious complication of total knee arthroplasty. Though there are many factors that might increase its risk, the use of propofol for maintaining general anesthesia could theoretically increase the incidence of infection because of its lipid component that supports bacterial growth. Nevertheless, the relationship between anesthetic maintenance agents and the occurrence of periprosthetic joint infection remains uncertain. Read More

Pachydermoperiostosis in a patient with chronic hepatitis B virus infection referred as acromegaly: a case report.

J Med Case Rep 2018 Mar 8;12(1):59. Epub 2018 Mar 8.

Department of Medicine and Therapeutics, School of Medicine and Dentistry, College of Health Sciences, University of Ghana, Legon, Accra, Ghana.

Background: Primary hypertrophic osteoarthropathy also known as pachydermoperiostosis is a rare genetic disorder that has often been confused with acromegaly because of similar clinical features. Vascular endothelial growth factors which have been implicated in the clinical features of pachydermoperiostosis, have also been shown to be present in chronic hepatitis and implicated in the malignant transformation of hepatitis B infection to hepatocellular carcinoma. To the best of our knowledge there is one reported case of pachydermoperiostosis with chronic hepatitis B infection. Read More

Department of Internal Medicine, Division of Rheumatology and School of Medicine, University of New Mexico Health Sciences Center, MSC 10 5550, 5th FL ACC, Albuquerque, NM, 87131, USA.

We hypothesized that constant compression of the knee would mobilize residual synovial fluid and promote successful arthrocentesis. Two hundred and ten knees with grade II-III osteoarthritis were included in this paired design study: (1) conventional arthrocentesis was performed with manual compression and success and volume (milliliters) determined; and (2) the intra-articular needle was left in place, and a circumferential elastomeric brace was tightened on the knee to provide constant compression. Arthrocentesis was attempted again and additional fluid volume was determined. Read More

Early loss of subchondral bone following microfracture is counteracted by bone marrow aspirate in a translational model of osteochondral repair.

Sci Rep 2017 03 27;7:45189. Epub 2017 Mar 27.

Center of Experimental Orthopaedics, Saarland University, Homburg, Germany.

Microfracture of cartilage defects may induce alterations of the subchondral bone in the mid- and long-term, yet very little is known about their onset. Possibly, these changes may be avoided by an enhanced microfracture technique with additional application of bone marrow aspirate. In this study, full-thickness chondral defects in the knee joints of minipigs were either treated with (1) debridement down to the subchondral bone plate alone, (2) debridement with microfracture, or (3) microfracture with additional application of bone marrow aspirate.

A Multicenter Study of Early Anti-inflammatory Treatment in Patients With Acute Anterior Cruciate Ligament Tear.

Am J Sports Med 2017 Feb 7;45(2):325-333. Epub 2016 Oct 7.

Cleveland Clinic Sports Health Center, Garfield Heights, Ohio, USA.

Background: It is increasingly recognized that biochemical abnormalities of the joint precede radiographic abnormalities of posttraumatic osteoarthritis (PTOA) by as much as decades. A growing body of evidence strongly suggests that the progression from anterior cruciate ligament (ACL) injury to PTOA is multifactorial, involving the interplay between biomechanical disturbances and biochemical homeostasis of articular cartilage.

Purpose: The purposes of this randomized study using an acute ACL injury model were to (1) evaluate the natural progression of inflammatory and chondrodegenerative biomarkers, (2) evaluate the relationship between subjective reports of pain and inflammatory and chondrodegenerative biomarkers, and (3) determine if postinjury arthrocentesis and corticosteroid injection offer the ability to alter this biochemical cascade.

The Therapeutic Effect of Intra-articular Normal Saline Injections for Knee Osteoarthritis: A Meta-analysis of Evidence Level 1 Studies.

Am J Sports Med 2017 Sep 27;45(11):2647-2653. Epub 2016 Dec 27.

Division of Sports Medicine, Department of Orthopedic Surgery, Rush University Medical Center, Chicago, Illinois, USA.

Background: Intra-articular normal saline (IA-NS) injections have been utilized as a placebo in a number of randomized controlled trials pertaining to the management of knee osteoarthritis (OA); however, it is believed that these "placebo" injections may have a therapeutic effect that has not been quantified in the literature.

Purpose: To (1) quantify the effect of IA-NS injections on patient-reported outcomes (PROs) and (2) compare postinjection PROs to established minimal clinically important difference (MCID) criteria to demonstrate a potential therapeutic effect.

Raleigh Orthopedic Clinic, Raleigh, NC, USA.

Background: Synovial fluid aspiration is a routine practice used by most orthopaedic surgeons to aid in the diagnosis of joint infection. In patients for whom there is a low pretest probability of infection, a positive culture-particularly if it is a broth-only culture-may be considered a contaminant, especially if the bacterial species are skin pathogens. To our knowledge no study has evaluated the incidence of contamination of aspirations from the native knee. Read More

The Bridge-Enhanced Anterior Cruciate Ligament Repair (BEAR) Procedure: An Early Feasibility Cohort Study.

Orthop J Sports Med 2016 Nov 21;4(11):2325967116672176. Epub 2016 Nov 21.

Division of Sports Medicine, Department of Orthopaedic Surgery, Boston Children's Hospital Boston, Massachusetts, USA.

Background: This study assessed the safety of the newly developed bridge-enhanced anterior cruciate ligament (ACL) repair (BEAR), which involves suture repair of the ligament combined with a bioactive scaffold to bridge the gap between the torn ligament ends. As the intra-articular environment is complex in its response to implanted materials, this study was designed to determine whether there would be a significant rate of adverse reaction to the implanted scaffold.

Hypothesis: The primary hypothesis was that the implanted scaffold would not result in a deep joint infection (arthrocentesis with positive culture) or significant inflammation (clinical symptoms justifying arthrocentesis but negative culture). Read More

Orthopedic disorders of the knee in hemophilia: A current concept review.

World J Orthop 2016 Jun 18;7(6):370-5. Epub 2016 Jun 18.

E Carlos Rodriguez-Merchan, Department of Orthopedic Surgery, La Paz University Hospital-IdiPaz, 28046 Madrid, Spain.

The knee is frequently affected by severe orthopedic changes known as hemophilic arthropathy (HA) in patients with deficiency of coagulation factor VIII or IX and thus this manuscript seeks to present a current perspective of the role of the orthopedic surgeon in the management of these problems. Lifelong factor replacement therapy (FRT) is optimal to prevent HA, however adherence to this regerous treatment is challenging leading to breakthrough bleeding. In patients with chronic hemophilic synovitis, the prelude to HA, radiosynovectomy (RS) is the optimal to ameliorate bleeding. Read More

Periprosthetic Joint Infection After Hip and Knee Arthroplasty: A Review for Emergency Care Providers.

Ann Emerg Med 2016 09 13;68(3):324-34. Epub 2016 Apr 13.

Department of Orthopedic Surgery, Rush University Medical Center, Chicago, IL.

Periprosthetic joint infection is among the most common modes of failure of a total hip or knee arthroplasty and can be a common concern when patients present to the emergency department for care. The initial evaluation for periprosthetic joint infection includes a history and physical examination, followed by radiographs (to rule out other causes of pain or failure) and then serum erythrocyte sedimentation rate and C-reactive protein testing. If the erythrocyte sedimentation rate and C-reactive protein level are elevated or if the clinical suspicion for infection is high, the joint should be aspirated and the fluid sent for culture, as well as for a synovial WBC count and differential, with optimal threshold values of 3,000 WBC/μL and 80% polymorphonuclear cells, respectively.
