Reducing ACL injury risk: A meta-analysis of prevention programme effectiveness.

Purpose: The aim of this study was to conduct a meta-analysis of the literature regarding anterior cruciate ligament (ACL) injury prevention programmes (IPPs) in order to assess the effectiveness of ACL prevention programmes based on current high-quality studies. The hypothesis was that the implementation of ACL IPPs significantly reduces the incidence of ACL ruptures compared to standard practice.

Methods: A meta-analysis of the literature was conducted using the databases PubMed, EMBASE, MEDLINE, CINHAL and Cochrane Central Register of Controlled Trials.

30-day and one-year readmission rate in 11,270 patients with surgical treatment for proximal femoral fractures across Austria.

Aims: Patients with proximal femoral fractures (PFFs) are often multimorbid, thus unplanned readmissions following surgery are common. We therefore aimed to analyze 30-day and one-year readmission rates, reasons for, and factors associated with, readmission risk in a cohort of patients with surgically treated PFFs across Austria.

Methods: Data from 11,270 patients with PFFs, treated surgically (osteosyntheses, n = 6,435; endoprostheses, n = 4,835) at Austrian hospitals within a one-year period (January to December 2021) was retrieved from the Leistungsorientierte Krankenanstaltenfinanzierung (Achievement-Oriented Hospital Financing).

Delayed Meniscus Repair Lowers the Functional Outcome of Primary ACL Reconstruction.

Background: Our purpose was to evaluate whether the time of intervention and the type of meniscus surgery (repair vs. partial meniscectomy) play a role in managing anterior cruciate ligament (ACL) reconstructions with concurrent meniscus pathologies.

Methods: We performed a prospective cohort study which differentiated between early and late ACL reconstructions with a cut-off at 3 months.

Are ChatGPT's Free-Text Responses on Periprosthetic Joint Infections of the Hip and Knee Reliable and Useful?

Background: This study aimed to evaluate ChatGPT's performance on questions about periprosthetic joint infections (PJI) of the hip and knee.

Methods: Twenty-seven questions from the 2018 International Consensus Meeting on Musculoskeletal Infection were selected for response generation. The free-text responses were evaluated by three orthopedic surgeons using a five-point Likert scale.

[Sterile puncture of large joints].

Objective: Puncture of large joints is performed for diagnostic purposes on the one hand and for the treatment of joint pathologies on the other. Puncture can be used for rapid pain relief by relieving effusions or intra-articular hematomas. The obtained puncture specimen allows immediate visual assessment and subsequent microscopic-cytological and microbiological evaluation in the laboratory.

Immunological reaction to magnesium-based implants for orthopedic applications. What do we know so far? A systematic review on studies.

Magnesium-based implants (Mg) became an attractive candidate in orthopedic surgery due to their valuable properties, such as osteoconductivity, biodegradability, elasticity and mechanical strength. However, previous studies on biodegradable and non-biodegradable metal implants showed that these materials are not inert when placed as they interact with host defensive mechanisms. The aim of this study was to systematically review available studies with Mg-based implants that investigated immunological reactions to these implants.

[Claims following distal Radius Fractures].

Background: As distal radius fractures as well as diagnostic and therapeutic options vary widely, there is an enormous potential for deficient convalescence and subsequent patient dissatisfaction. The aim of this study is the evaluation of malpractice in distal radius fracture management, which could help to draw conclusions regarding optimization and prevention as well as raising patient satisfaction and minimizing subsequent costs.

Material And Methods: Files and patient data of all distal radius fracture complaints regarding one public hospital operator in a period between 2007 and 2017 were reviewed and subjected to descriptive statistics.

Kinematic and Kinetic Gait Parameters Can Distinguish between Idiopathic and Neurologic Toe-Walking.

The differentiation between mild forms of toe-walking (equinus) in cerebral palsy (CP) and idiopathic toe-walking (ITW) is often clinically challenging. This study aims to define kinematic and kinetic parameters using 3D gait analysis to facilitate and secure the diagnosis of "idiopathic toe-walking". We conducted a retrospective controlled stratified cohort study.

Leg length measures appear inaccurate in the early phase following total hip arthroplasty.

The aims of this study were to (1) assess reliability of leg length discrepancy (LLD) measurements at different anatomical landmarks, (2) longitudinally investigate LLD in patients within the first year following total hip arthroplasty (THA) and to (3) correlate changes in LLD with functional outcome. Ninety-nine patients with short stem THA (53.3% males, mean age: 61.

Positive effect of colors and art in patient rooms on patient recovery after total hip or knee arthroplasty : A randomized controlled trial.

Background: Environmental stimuli and well-being are considered to be significant factors in patients' rehabilitation. The aim of this study was to describe the effect of colors and art in hospital rooms on patients' recovery after total hip or knee arthroplasty.

Methods: We performed a prospective randomized, controlled study including 80 patients.

What are the Implications of Excessive Internet Searches for Medical Information by Orthopaedic Patients?

Background: Cyberchondria may be defined as heightened distress evoked through excessive searches of the internet for medical information. In healthy people, cyberchondria is associated with a greater intolerance of uncertainty and greater health anxiety. These relationships are likely bidirectional.

What Is the Relationship of Fear Avoidance to Physical Function and Pain Intensity in Injured Athletes?

Background: Fear avoidance can play a prominent role in maladaptive responses to an injury. In injured athletes, such pain-related fear or fear avoidance behavior may have a substantial influence on the recovery process. Specifically, it may explain why some are able to reach their preinjury abilities, whereas others are unable to return to sport.

Ulnar Neck Fractures Associated with Distal Radius Fractures.

 There is little published data to guide management of ulnar neck fractures associated with fractures of the distal radius.  As unplanned surgery usually reflects adverse events and this injury combination is relatively uncommon, we used a large database to study the incidence of unplanned surgeries after surgical and nonsurgical treatment of distal metaphyseal ulna fractures associated with a distal radius fracture and identify factors associated with these unplanned surgeries.  We identified 277 patients with an ulnar neck fracture associated with a distal radius fracture.

Pain anxiety differentially mediates the association of pain intensity with function depending on level of intolerance of uncertainty.

Uncertainty about symptom duration, cause, prognosis and treatment is common in patients who seek medical care, yet individual ability to manage this uncertainty varies. Intolerance of uncertainty is considered an important factor in the etiology and persistence of negative emotions- in particular, depression and anxiety. We explored the contribution of intolerance of uncertainty to anxiety due to pain and physical function in patients seeking care at an orthopedic medical practice.

Type D personality in patients with upper extremity musculoskeletal illness: Internal consistency, structural validity and relationship to pain interference.

Objective: Type D personality - the joint tendency toward negative affectivity (NA) and social inhibition (SI) - is associated with greater symptom perception and negative health outcomes among various patient populations. We investigated Type D personality among patients with upper extremity musculoskeletal illness.

Method: In cross-sectional design, we estimated the prevalence of Type D personality in this population and explored the associations of two different Type D conceptualizations (i.

Bidirectional mediation of depression and pain intensity on their associations with upper extremity physical function.

Pain intensity and symptoms of depression are correlated and individually associated with decreased physical function. We compared two explanatory mediation models; one with depression as mediator of the association of pain intensity with physical function and the other one with pain intensity as the mediator of the effect of depression on physical function. In a cross-sectional study, 102 patients with upper extremity musculoskeletal illness completed measures of pain intensity, PROMIS depression CAT, PROMIS physical function-upper extremity CAT and demographics.

Emotion regulation strategies mediate the associations of positive and negative affect to upper extremity physical function.

Background: The Gross process model of emotion regulation holds that emotion-eliciting situations (e.g. musculoskeletal illness) can be strategically regulated to determine the final emotional and behavioral response.

Pain Catastrophizing Mediates the Effect of Psychological Inflexibility on Pain Intensity and Upper Extremity Physical Function in Patients with Upper Extremity Illness.

Background: Psychological inflexibility-the inability to take value-based actions in the presence of unwanted thoughts, feelings, or bodily symptoms-is associated with negative health outcomes including depression and anxiety.

Objective: We aimed to determine the association between the general construct of psychological inflexibility and pain intensity, and upper extremity physical function in patients with musculoskeletal illness in an orthopedics practice. We also set out to test multiple-mediator models proposing that psychological inflexibility affects pain intensity and upper extremity physical function directly, as well as indirectly through depression, anxiety, and pain catastrophizing.

PHB, crystalline and amorphous magnesium alloys: promising candidates for bioresorbable osteosynthesis implants?

In this study various biodegradable materials were tested for their suitability for use in osteosynthesis implants, in particular as elastically stable intramedullary nails for fracture treatment in paediatric orthopaedics. The materials investigated comprise polyhydroxybutyrate (PHB), which belongs to the polyester family and is produced by microorganisms, with additions of ZrO2 and a bone graft substitute; two crystalline magnesium alloys with significantly different degradation rates ZX50 (MgZnCa, fast) and WZ21 (MgYZnCa, slow); and MgZnCa bulk metallic glasses (BMG). Push-out tests were conducted after various implantation times in rat femur meta-diaphysis to evaluate the shear forces between the implant material and the bone.

Magnesium alloys for temporary implants in osteosynthesis: in vivo studies of their degradation and interaction with bone.

This study investigates the bone and tissue response to degrading magnesium pin implants in the growing rat skeleton by continuous in vivo microfocus computed tomography (μCT) monitoring over the entire pin degradation period, with special focus on bone remodeling after implant dissolution. The influence of gas release on tissue performance upon degradation of the magnesium implant is also addressed. Two different magnesium alloys - one fast degrading (ZX50) and one slowly degrading (WZ21) - were used for evaluating the bone response in 32 male Sprague-Dawley rats.
