Categorization of changes in the Oxford Knee Score after total knee replacement: an interpretive tool developed from a data set of 46,094 replacements.

Objectives: The objective of the study was to create an interpretive categorical classification for the transition in the Oxford Knee Score (OKS) change score (ΔOKS) using the anchor-based method.

Study Design And Setting: Registry data from 46,094 total knee replacements from the year 2014/15, were accessed via the Health and Social Care Information Center official website. Data included preoperative and 6-month follow-up OKS and response to the transition anchor question.

Influence of day of surgery and prediction of LOS > 2 days after fast-track hip and knee replacement.

Background and purpose - Enhanced recovery programs have reduced length of stay (LOS) after hip and knee arthroplasty (THA/TKA). Although risk factors disposing to prolonged LOS are well documented, there is limited information on the role of weekday of surgery. This study analyzed the role of weekday of surgery and other potential risk factors for LOS > 2 days.

Patient-reported outcomes of 7133 distal femoral, patellar, and proximal tibial fracture patients: A national cross-sectional study with one-, three-, and five-year follow-up.

Background: Few studies have described patient-reported outcome measures (PROMs) in knee fracture patients. We reported knee-specific and generic median PROM scores after knee fracture and identified risk factors for poor outcome defined by low median PROM scores.

Methods: In a Danish cross-sectional study of 7133 distal femoral, patellar, and proximal tibial fracture patients during 2011-2017, OKS, FJS-12, EQ5D-5L Index, and EQ5D-5L Visual Analogue Scale (VAS), were collected electronically (response rate 53%; median age 60; 63% female).

Unicompartmental knee arthroplasty undertaken using a fast-track protocol.

Aims: The aim of this prospective multicentre study was to describe trends in length of stay and early complications and readmissions following unicompartmental knee arthroplasty (UKA) performed at eight different centres in Denmark using a fast-track protocol and to compare the length of stay between centres with high and low utilization of UKA.

Methods: We included data from eight dedicated fast-track centres, all reporting UKAs to the same database, between 2010 and 2018. Complete ( > 99%) data on length of stay, 90-day readmission, and mortality were obtained during the study period.

Venous thromboembolism after fast-track unicompartmental knee arthroplasty - A prospective multicentre cohort study of 3927 procedures.

Introduction: Unicompartmental knee arthroplasty (UKA) has increased due to potential favourable complication rates when compared to total knee arthroplasty (TKA). Although venous thromboembolism (VTE) is a well-documented complication after TKA limited data is available after UKA and mostly presented as secondary findings in observational comparisons to TKA. There is a lack of fast-track UKA VTE studies and no guidelines on thromboprophylaxis.

Why are patients still in hospital after fast-track, unilateral unicompartmental knee arthroplasty.

Background and purpose - Previous studies have investigated risk factors related to prolonged length of stay following total knee arthroplasty (TKA), but little is known about specific factors resulting in continued hospitalization within the 1st postoperative days after unicompartmental knee arthroplasty (UKA). We investigated what specific factors prevent patients from being discharged on the day of surgery (DOS) and the first postoperative day (POD-1) following primary UKA in a fast-track setting.Patients and methods - We prospectively collected data on 100 consecutive and unselected medial UKA patients operated from December 2017 to May 2019.

Efficacy of early controlled motion of the ankle compared with immobilisation in non-operative treatment of patients with an acute Achilles tendon rupture: an assessor-blinded, randomised controlled trial.

Background: Early controlled motion (ECM) of the ankle is widely used in the non-operative treatment of acute Achilles tendon rupture, although its safety and efficacy have not been investigated properly in a randomised set-up.

Purpose/aim Of The Study: To investigate if ECM of the ankle was superior to immobilisation in the treatment of acute Achilles tendon rupture.

Materials And Methods: This was an assessor-blinded, randomised controlled trial with patients allocated in a 1:1 ratio to one of two parallel groups.

Gait Function and Postural Control 4.5 Years After Nonoperative Dynamic Treatment of Acute Achilles Tendon Ruptures.

Background: An Achilles tendon rupture (ATR) is known to cause persistent biomechanical deficits such as decreased muscle strength in end-range plantar flexion and reduced tendon stiffness.

Purpose/hypothesis: This study aimed to examine whether sustained asymmetries were present in dynamic stiffness and kinematic and kinetic variables in gait and single-leg balance at 4.5-year follow-up in conservatively treated patients recovering from an ATR.

Medial unicompartmental knee arthroplasty: increasingly uniform patient demographics despite differences in surgical volume and usage-a descriptive study of 8,501 cases from the Danish Knee Arthroplasty Registry.

Background and purpose - Using contemporary indications, up to 50% of patients undergoing knee arthroplasty are eligible for unicompartmental knee arthroplasty (UKA), and lower UKA use likely reflects a restrictive approach to patient selection. Since broader indications have been successfully introduced, and low surgical volume and UKA percentage (usage) are associated with higher revision rates, it is of interest whether the actual use of UKA has changed accordingly. We explored this by assessing time trends in patient demographics and whether these are associated with center UKA volume and usage.

Incidence of surgical interventions for metastatic bone disease in the extremities: a population-based cohort study.

Background: The incidence of surgery due to metastatic bone disease in the extremities (MBDex) and postoperative survival remain uninvestigated in the population. The aim of the current study was: to identify (1) incidence, demographics and survival of a population-based cohort of patients having surgery for MBDex (2) rate of referrals and referral pattern to a musculoskeletal tumour centre (MTC).

Material And Method: A prospective study of a consecutive population-based cohort of patients having surgery for MBDex from 2014 to 2016.

Weight affects survival of primary total knee arthroplasty: study based on the Danish Knee Arthroplasty Register with 67,810 patients and a median follow-up time of 5 years.

Background and purpose - Obesity is a rising issue worldwide and growing evidence supports poor outcome amongst obese patients following total knee arthroplasty (TKA). Using nationwide registries we investigated the association between bodyweight and risk of revision of primary TKA. Patients and methods - All primary TKA performed during 1997-2015, weight at time of primary TKA and subsequent TKA revisions were identified in the Danish Knee Arthroplasty Register (DKR).

Can an off-the-rack orthotic stiletto alter pressure and comfort scores in the forefoot, arch and heel?

The study sought to investigate whether an orthotic stiletto could modulate the pressure and comfort under the forefoot, arch and heel that stiletto wearers experience. Twenty-two women participated. We measured the peak pressure and pressure-time integral for orthotic stilettos with built-in metatarsal pad, heel cup and arch support; standard stilettos without inlays; and trainers.

MAXIMAL HIP AND KNEE MUSCLE STRENGTH ARE NOT RELATED TO NEUROMUSCULAR PRE-ACTIVITY DURING SIDECUTTING MANEUVER: A CROSS-SECTIONAL STUDY.

Background: Reduced lower extremity muscle strength as well as reduced lower extremity muscle pre-activity (defined as muscular activity just prior to initial ground contact) during high-risk movements are factors related to increased risk of non-contact ACL injury in adolescent female athletes. A strong relationship exists between muscle strength and muscle activity obtained during an isometric contraction, however, whether these two measures are related when muscle activity is obtained during a movement associated with a high risk of non-contact ACL injury is not known. Absence or presence of such a relationship may have implications for which training modalities to choose in the prevention of ACL injuries.

Development and reliability of the Achilles Tendon Length Measure and comparison with the Achilles Tendon Resting Angle on patients with an Achilles tendon rupture.

Background: There is a need for a valid, reliable, and easily applicable clinical measure of the length of the Achilles tendon (AT) after rupture. This study examines the reliability of a new ruler based measurement, the Achilles Tendon Length Measure (ATLM) in comparison with the goniometer-based Achilles Tendon Resting Angle (ATRA).

Methods: Measurements were performed by two independent physiotherapists eight weeks after AT rupture on 28 patients treated non-operatively.

No association between surgical delay and mortality following distal femoral fractures. A study from the danish fracture database collaborators.

Background: The purpose of this study was to investigate whether surgical delay or the educational level of surgeon is associated with early mortality in patients with distal femoral fractures.

Methods: 392 consecutive patients aged ≥50 years registered in the Danish Fracture Database for surgery of a non-pathological, closed, low-energy distal femoral fracture (AO33A-C) were included. Data included age, gender, American Society of Anaesthesiologists (ASA) score, type of fracture, educational level of surgeon and surgical delay.

Local dynamic stability during treadmill walking can detect children with developmental coordination disorder.

Objective: Developmental coordination disorder (DCD) is an innate impairment of motor coordination that affects basic locomotion and balance. This study investigated local dynamic stability of trunk accelerations during treadmill walking as an objective evaluation of gait stability and the sensitivity and specificity of this measure to discriminate children with DCD from typically developing children.

Method: Eight children with DCD and ten age- and gender-matched typically developing children (TD) walked four minutes on a treadmill.

Severe Functional Debilitations After Complications Associated With Acute Achilles Tendon Rupture With 9 Years of Follow-Up.

The purpose of the present study was to investigate the long-term effect of deep infection, sural nerve injury, and repeat rupture in the treatment of acute Achilles tendon rupture. A total of 324 patients had made a claim to the Danish Patient Insurance Association from 1992 to 2010 for a complication after acute Achilles tendon rupture. Of the 324 patients, 119 (36.

Low Risk of Thromboembolic Events After Routine Administration of Tranexamic Acid in Hip and Knee Arthroplasty.

Background: The blood-conserving effect of intravenous (IV) tranexamic acid (TXA) is well-documented for total hip arthroplasty (THA) and total knee arthroplasty (TKA). However, the risk of thromboembolic (TE) events after routine use of TXA is unclear and the safety profile is debated. This retrospective study investigates patient characteristics, occurrences, and predictors of TE events after routine administration of IV TXA in THA and TKA.

Noticeable Variations in the Educational Exposure During Residency in Danish Orthopedic Departments.

Objective: The objective of the study was to examine the educational exposure during residency in Danish orthopedic departments.

Design: Questionnaire-based cross-sectional study.

Setting: Data were gathered from January 1, 2014 to April 30, 2014 through a nationwide web-based questionnaire containing 15 questions within the areas of workload, surgical procedures, outpatient clinic, and research activities.

Lacking evidence for performance of implants used for proximal femoral fractures - A systematic review.

Introduction: Evaluation of the long-term performance of implants used in trauma surgery relies on post-marked clinical studies since no registry based implant assessment exists. The purpose of this study was to evaluate the evidence of performance of implants currently used for treating proximal femoral fractures (PFF) in Denmark.

Method: PubMed was searched for clinical studies on primary PFF with follow-up ≥12 months, reporting implant-related failure and evaluating one of following: DHS, CHS, HipLoc, Gamma3, IMHS, InterTan, PFN, PFNA or PTN.

Achilles tendon Total Rupture Score at 3 months can predict patients' ability to return to sport 1 year after injury.

Purpose: To investigate how the Achilles tendon Total Rupture Score (ATRS) at 3 months and 1 year after injury is associated with a patient's ability to return to work and sports as well as to investigate whether sex and age influence ATRS after 3 months and 1 year.

Method: This is a retrospective study analysing the data from the Danish Achilles tendon Database. A total of 366 patients were included.

Reliability and agreement between 2 strength devices used in the newly modified and standardized Constant score.

Hypothesis: The new and standardized test protocol for the Constant score (CS) provides new methodology, but different devices are still used for shoulder strength testing. It was hypothesized that strength measurements using the IsoForceControl (IFC) dynamometer (MDS Medical Device Solutions, Oberburg, Switzerland) would provide results comparable with the IDO isometer (Innovative Design Orthopaedics, Redditch, UK).

Materials And Methods: Sixty healthy subjects, aged 19 to 83 years, were studied, with 5 men and 5 women in each of 6 ten-year age groups.

Does bony hip morphology affect the outcome of treatment for patients with adductor-related groin pain? Outcome 10 years after baseline assessment.

Background: Adductor-related groin pain and bony morphology such as femoroacetabular impingement (FAI) or hip dysplasia can coexist clinically. A previous randomised controlled trial in which athletes with adductor-related groin pain underwent either passive treatment (PT) or active treatment (AT) showed good results in the AT group. The primary purpose of the present study was to evaluate if radiological signs of FAI or hip dysplasia seem to affect the clinical outcome, initially and at 8-12 years of follow-up.

Treatment of acute Achilles tendon rupture in Scandinavia does not adhere to evidence-based guidelines: a cross-sectional questionnaire-based study of 138 departments.

The best treatment of acute Achilles tendon rupture has been discussed for decades. During the past half decade, evidence has increased in favor of nonoperative treatment and dynamic and weightbearing rehabilitation. We hypothesized that the treatment strategies would show great variation and that adherence to evidence-based recommendations would not be as good as desired.
