Bone marrow lesions in knee osteoarthritis assessed by dynamic contrast-enhanced MRI with histopathological correlations.

Background: Bone marrow lesions (BMLs) in knee osteoarthritis (OA) have been assessed histopathologically and by dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI); however, a direct comparison of the results has not been reported.

Purpose: To evaluate and compare the findings by DCE-MRI and histopathology of subchondral BMLs in knee OA.

Material And Methods: In total, 19 patients with medial tibiofemoral knee OA undergoing total knee arthroplasty were analyzed.

Prognostic factors of knee pain and function 12 months after total knee arthroplasty: A prospective cohort study of 798 patients.

Background: Approximately 20% of patients undergoing total knee arthroplasty (TKA) do not experience long-term improvements. Our aim was to identify prognostic factors of knee pain and function 12 months after TKA.

Methods: In a prospective cohort study, 1026 patients underwent primary TKA between 2018 and 2020.

Feasibility, safety, and patient-reported outcomes 90 days after same-day total knee arthroplasty: a matched cohort study.

Background And Purpose: Despite increased attention to and acceptance of fast-track procedures, there is a lack of studies concerning discharge on the day of surgery (DOS) following total knee arthroplasty (SD-TKA). We evaluated the feasibility of SD-TKA, and compared safety and patient-reported outcomes (PROs) between patients undergoing SD-TKA and patients undergoing standard TKA.

Patients And Methods: A SD-TKA group (n = 101) was matched 1:1 to a standard TKA group (n = 101) on age, sex, and ASA score.

Improving the referral pattern of patients with knee osteoarthritis to the orthopaedic surgeon: Development and evaluation of a new screening algorithm based on patient-reported data and radiographs.

Introduction: Many patients with knee osteoarthritis referred to orthopaedic surgeons are not eligible for surgery and might benefit from being examined by other healthcare professionals. The objective of this study was to develop and test a screening algorithm to define relevant referral to the OS.

Methods: Prior to clinical examination, 173 consecutive patients referred to the orthopaedic outpatient clinic completed questionnaires, and radiographic osteoarthritis severity was graded.

Analgesia of Combined Femoral Triangle and Obturator Nerve Blockade Is Superior to Local Infiltration Analgesia After Total Knee Arthroplasty With High-Dose Intravenous Dexamethasone.

Background And Objectives: High-dose intravenous dexamethasone reduces the postoperative opioid requirement and is often included in the multimodal analgesia strategy after total knee arthroplasty (TKA). Combined obturator nerve and femoral triangle blockade (OFB) reduces the opioid consumption and pain after TKA better than local infiltration analgesia (LIA). The question is whether preoperative high-dose intravenous dexamethasone would cancel out the superior analgesic effect of OFB compared with LIA.

Mobile- vs. fixed-bearing total knee replacement.

Background And Purpose: It is unclear whether mobile-bearing (MB) total knee arthroplasties reduce the risk of tibial component loosening compared to fixed-bearing (FB) designs. This randomized study investigated implant migration, periprosthetic bone mineral density (BMD), and patient-reported outcomes (Oxford knee score)-all at 2 years-for the P.F.

Missed injuries in a level I trauma center.

Background: Major trauma presents major diagnostic and therapeutic problems. Any delay in providing the treatment necessary may lead to increased morbidity and mortality, prolonged length of hospital stay, and increased cost. This study was undertaken to determine the extent, contributing factors, and implication of missed injuries and relate them to the three surveys in a Danish Level I trauma center.
