Patients with hip resurfacing arthroplasty are not physically more active than those with a stemmed total hip.

Acta Orthop 2020 Jun 4:1-5. Epub 2020 Jun 4.

Luxembourg Institute of Health, Human Motion, Orthopedics, Sports Medicine, Digital Methods (HOSD), Luxembourg, Luxembourg.

Background and purpose - Hip resurfacing arthroplasty (HRA) was designed for the highly active patient because of the various theoretical advantages compared with stemmed total hip arthroplasty (THA), but has shown high failure rates. Physical activity (PA) after arthroplasty is frequently determined with the use of questionnaires, which are known for their subjective nature, recall bias, and ceiling effect. These disadvantages are not applicable to physical activity monitoring (AM) using sensors. Read More

No association between waiting time to surgery and mortality for healthier patients with hip fracture: a nationwide Swedish cohort of 59,675 patients.

Acta Orthop 2020 Apr 24:1-6. Epub 2020 Apr 24.

Institution of Clinical Sciences, Intervention and Technology (CLINTEC) Karolinska Institutet, Stockholm.

Background and purpose - Waiting time to surgery for patients with hip fractures and its potential association with mortality has been frequently studied with the hypothesis that longer waiting time is associated with adverse outcomes. However, despite numerous studies, there is no consensus regarding which time frames are appropriate, and whether some patients are more vulnerable to waiting than others. We explored the association between waiting time to surgery and short-term mortality and whether sex, age, surgical method, and comorbidity (ASA) modified this association. Read More

How do EQ-5D-3L and EQ-5D-5L compare in a Swedish total hip replacement population?

Acta Orthop 2020 Apr 2:1-7. Epub 2020 Apr 2.

Swedish Hip Arthroplasty Register, Gothenburg.

Background and purpose - To better detect small changes in postoperative outcome following total hip replacement (THR), the Swedish Hip Arthroplasty Register (SHAR) has decided to change from the EQ-5D-3L (3L) to the EQ-5D-5L (5L). To enable comparison of results obtained with use of the 2 versions of EQ-5D, transferal of results between the questionnaires used is necessary. We assessed the measurement properties of the EQ-5D-5L compared with the EQ-5D-3L, preoperatively and 1-year postoperatively in a Swedish THR population. Read More

Prognostic factors for inpatient functional recovery following total hip and knee arthroplasty: a systematic review.

Acta Orthop 2020 Apr 2:1-6. Epub 2020 Apr 2.

Faculty of Health Sciences and Medicine, Bond University, Gold Coast, Australia.

Background and purpose - Essential for safe and timely hospital discharge, inpatient functional recovery following lower limb arthroplasty is also variable. A previous systematic review reported moderate and conflicting levels of evidence regarding patient-related predictors of inpatient recovery for primary total hip arthroplasty (THA). A systematic review of surgical prognostic factors for inpatient recovery following THA or total knee arthroplasty (TKA) is yet to be undertaken. Read More

Mid-term results of hindfoot arthrodesis with a retrograde intra-medullary nail in 24 patients with diabetic Charcot neuroarthropathy.

Acta Orthop 2020 Apr 1:1-5. Epub 2020 Apr 1.

Department of Orthopaedics and Traumatology, İstanbul School of Medicine, İstanbul University, İstanbul, Turkey.

Background and purpose - Hindfoot arthrodesis using retrograde intramedullary nailing assumes a critical role in limb salvage for patients with diabetic Charcot neuro-arthropathy (CN). However, this procedure is compelling and fraught with complications in diabetic patients. We report the mid-term clinical and radiological outcomes of retrograde intramedullary nailing for severe foot and ankle deformity in patients with diabetic CN. Read More

Increased risk for dislocation after introduction of the Continuum cup system: lessons learnt from a cohort of 1,381 THRs after 1-year follow-up.

Acta Orthop 2020 Apr 1:1-7. Epub 2020 Apr 1.

Coxa Hospital for Joint Replacement, and Faculty of Medicine and Health Technology, University of Tampere, Tampere, Finland.

Background and purpose - The introduction of new total hip replacements (THRs) is known to be associated with an increased risk for complications. On completion of a competitive procurement process, a new uncemented cup system was introduced into general use at our institution in 2016. We launched this study after the introduction to assess (1) the incidence of early dislocations of the old (Pinnacle) and the new (Continuum) cup systems, and (2) whether the cup design would affect the risk for dislocation.

14-year hip survivorship after periacetabular osteotomy: a follow-up study on 1,385 hips.

Acta Orthop 2020 Feb 28:1-7. Epub 2020 Feb 28.

Department of Orthopaedic Surgery, Aarhus University Hospital, Aarhus N, Denmark.

Background and purpose - Few studies have evaluated the long- and mid-term outcomes after minimally invasive periacetabular osteotomy (PAO). We investigated: (1) the long-term hip survival rate after PAO; (2) the risk of complications and additional surgery after PAO; and (3) the hip function at different follow-up points.Patients and methods - We reviewed 1,385 hips (1,126 patients) who underwent PAO between January 2004 and December 2017.

Greater early migration of a short-stem total hip arthroplasty is not associated with an increased risk of osseointegration failure: 5th-year results from a prospective RSA study with 39 patients, a follow-up study.

Acta Orthop 2020 Feb 28:1-6. Epub 2020 Feb 28.

Laboratory for Biomechanics and Biomaterials, Hannover Medical School.

Background and purpose - Short-stem hip arthroplasty has been a viable alternative to standard stems for the treatment of hip osteoarthritis for over 10 years. This study assessed whether a correlation existed between a greater initial increase in implant migration and inferior clinical outcomes at 5 years postoperatively. Results on these patients after 2 years have been published previously. Read More
