High annual surgeon volume reduces the risk of adverse events following primary total hip arthroplasty: a registry-based study of 12,100 cases in Western Sweden.

Acta Orthop 2019 Feb 14:1-15. Epub 2019 Feb 14.

a Department of Orthopaedics, Institute of Clinical Sciences, The Sahlgrenska Academy , University of Gothenburg , Gothenburg , Sweden.

Background and purpose - Most earlier publications investigating whether annual surgeon volume is associated with lower levels of adverse events (AE), reoperations, and mortality are based on patient cohorts from North America. There is also a lack of adjustment for important confounders in these studies. Therefore, we investigated whether higher annual surgeon volume is associated with a lower risk of adverse events and mortality within 90 days following primary total hip arthroplasty (THA).

Early gain in pain reduction and hip function, but more complications following the direct anterior minimally invasive approach for total hip arthroplasty: a randomized trial of 100 patients with 5 years of follow up.

Acta Orthop 2018 Oct;89(5):484-489

a Department of Clinical Sciences, Intervention and Technology, Karolinska Intitutet, Department of Orthopedics , Karolinska University Hospital , Stockholm ;

Background and purpose - The minimally invasive direct anterior (DA) approach for total hip arthroplasty (THA) is supposed to reduce surgical tissue trauma. We hypothesized that patients operated with the DA technique would have less postoperative pain and better hip function compared with a group operated with a conventional direct lateral (DL) approach. Patients and methods - 100 patients with hip osteoarthritis scheduled for THA were equally randomized to surgery through either DA or DL. Read More

Higher mid-term revision rates of posterior stabilized compared with cruciate retaining total knee arthroplasties: 133,841 cemented arthroplasties for osteoarthritis in the Netherlands in 2007-2016.

Acta Orthop 2018 Dec 23;89(6):640-645. Epub 2018 Oct 23.

d Department of Orthopaedic Surgery , Leiden University Medical Center , Leiden , The Netherlands.

Background and purpose - The preference for a cruciate retaining (CR) or posterior stabilized (PS) TKA (total knee arthroplasty) system varies greatly between Dutch hospitals, independent of patient characteristics. We examined mid-term revision rates for men and women of different age categories. Patients and methods - We included all 133,841 cemented fixed-bearing primary CR or PS TKAs for osteoarthritis reported in the Dutch Arthroplasty Register (LROI) in 2007-2016. Read More

Nonagenarians qualify for total knee arthroplasty: a report on 329 patients from the Swedish Knee Arthroplasty Register 2000-2016.

Acta Orthop 2019 Feb 18;90(1):53-59. Epub 2018 Oct 18.

b Lund University , Faculty of Medicine, Department of Clinical Sciences Lund, Orthopedics , Lund , Sweden ;

Background and purpose - The nonagenarian (those aged 90 years and older) population is expected to double in the next 20 years. This demographic age quake may have a significant impact on the incidence of total knee arthroplasty (TKA), although current literature provides limited data. We examined death and revision rates, patient-reported outcomes (PROs) and bias on patient selection of nonagenarian patients operated on with TKA for osteoarthritis (OA) between 2000 and 2016.

Abaloparatide versus teriparatide: a head to head comparison of effects on fracture healing in mouse models.

Acta Orthop 2018 Dec 18;89(6):674-677. Epub 2018 Oct 18.

a Orthopaedics, Department of Clinical and Experimental Medicine, Faculty of Health Sciences , Linköping University , Linköping , Sweden.

Background and purpose - Teriparatide accelerates fracture healing in animals and probably in man. Abaloparatide is a new drug with similar although not identical effects on the teriparatide receptor. Given at 4 times the teriparatide dose in a human osteoporosis trial, abaloparatide increased bone density more than teriparatide, and both reduced fracture risk. Read More

F-FDG-PET uptake in non-infected total hip prostheses.

Acta Orthop 2018 Dec 18;89(6):634-639. Epub 2018 Oct 18.

c Department of Medical Microbiology and Infection Prevention , University of Groningen, University Medical Center Groningen , Groningen , the Netherlands.

Background and purpose - F-fluorodeoxyglucose positron emission tomography (FDG-PET) can be used in the diagnostic work-up of a patient with suspected periprosthetic joint infection (PJI) but, due to a lack of accurate interpretation criteria, this technique is not routinely applied. Since the physiological uptake pattern of FDG around a joint prosthesis is not fully elucidated, we determined the physiological FDG uptake in non-infected total hip prostheses. Patients and methods - Patients treated with primary total hip arthroplasty (1995-2016) who underwent a FDG-PET/CT for an indication other than a suspected PJI were retrospectively evaluated.
