In non-elite athletes, women are more likely to return to sports after anterior cruciate ligament reconstruction: a retrospective cohort study.

Background: The desire to return to sports (RTS) and return to performance at preinjury level (RTSP) is a common motivator for athletes undergoing anterior cruciate ligament (ACL) reconstructive surgery. However, for non-elite athletes little is known about the patient and surgical variables influencing RTS/RTSP. Purpose was to determine which patient or surgical variables had an effect on RTS/RTSP in non-elite athletes.

Responsiveness and interpretability of the pain subscale of the Knee and Hip Osteoarthritis Outcome Scale (KOOS and HOOS) in osteoarthritis patients according to COSMIN guidelines.

Background: The pain subscales of the Knee and Hip Osteoarthritis Outcome Scores (KOOS and HOOS) are among the most frequently applied, patient reported outcomes to assess pain in osteoarthritis patients and evaluation of the results after Total Knee Arthroplasty (TKA) and Total Hip Arthroplasty (THA). For the evaluation of change over time it is essential to know the responsiveness and interpretability of these measurement instruments. Aim of this study is to investigate responsiveness and interpretability of the KOOS and HOOS pain subscales in patients with knee or hip OA and patients after TKA and THA as recommended by COSMIN guidelines.

Effectiveness of rehabilitation for working-age patients after a total hip arthroplasty: a comparison of usual care between the Netherlands and Germany.

Background: Postoperative rehabilitation after primary total hip arthroplasty (p-THA) differs between the Netherlands and Germany. Aim is to compare clinical effectiveness and to get a first impression of cost effectiveness of Dutch versus German usual care after p-THA.

Methods: A transnational prospective controlled observational trial.

Elbow joint biomechanics during ADL focusing on total elbow arthroplasty - a scoping review.

Background: Overloading is hypothesized to be one of the failure mechanisms following total elbow arthroplasty (TEA). It is unclear whether the current post-operative loading instruction is compliant with reported failure mechanisms. Aim is therefore to evaluate the elbow joint load during activities of daily living (ADL) and compare these loads with reported failure limits from retrieval and finite element studies.

Functional recovery after reduced pediatric fractures of the forearm with respect to perceived limitations, common post-traumatic symptoms, range of motion, and dexterity: a prospective study.

Purpose: Studies on functional recovery after pediatric forearm fractures are scarce. Outcome measures are usually (retrospectively) incorporated to compare treatments. How these parameters recover has only rarely fallen within the scope.

Young men are at higher risk of failure after ACL hamstring reconstructions: a retrospective multivariate analysis.

Background: Results of ACL reconstruction are influenced by both patient and surgical variables. Until now a significant amount of studies have focused on the influence of surgical technique on primary outcome, often leaving patient variables untouched. This study investigates the combined influence of patient and surgical variables through multivariate analysis.

Mid-term results of the Latitude primary total elbow arthroplasty.

Background: The Latitude total elbow prosthesis is a third-generation implant, developed to restore the natural anatomy of the elbow. Literature on this prosthesis is scarce. The aim of this study was to analyze the mid-term results of the Latitude total elbow prosthesis.

Explicit teaching in the operating room: Adding the why to the what.

Context: Residents need their supervisors in the operating room to inform them on how to use expertise in present and future occasions. A few studies hint at such explicit teaching behaviour, however without explaining its underlying mechanisms. Understanding and improving explicit teaching becomes more salient nowadays, as access of residents to relevant procedures is decreasing, while end-terms of training programs remain unchanged: high quality patient care.

Triceps Insufficiency After Total Elbow Arthroplasty: A Systematic Review.

Background: The incidence of triceps insufficiency after total elbow arthroplasty (TEA) varies in the literature, and a consensus on treatment strategy is lacking. We review the incidence, the risk factors, the clinical presentation, and the diagnosis and treatment of triceps insufficiency after TEA. Based on this information, we have formulated recommendations for clinical practice.

Prospective cohort study comparing a triceps-sparing and triceps-detaching approach in total elbow arthroplasty: a protocol.

Background: New surgical approaches have been developed to optimise elbow function after total elbow arthroplasty (TEA). Currently, there is no consensus on the best surgical approach. This study aims to investigate the functional outcomes, prosthetic component position and complication rates after a triceps-sparing and a triceps-detaching approach in TEA.

Good results at 2-year follow-up of a custom-made triflange acetabular component for large acetabular defects and pelvic discontinuity: a prospective case series of 50 hips.

Background and purpose - Custom triflange acetabular components (CTACs) are suggested as good solutions for large acetabular defects in revision total hip arthroplasty. However, high complication rates have been reported and most studies are of limited quality. This prospective study evaluates the performance of a CTAC in patients with large acetabular defects including pelvic discontinuity.

Fingerprints of Teaching Interactions: Capturing and Quantifying How Supervisor Regulate Autonomy of Residents in the Operating Room.

Objective: Supervisors and residents agree that entrusted autonomy is central to learning in the Operating Room (OR), but supervisors and residents hold different opinions about entrustment: residents regularly experience that they receive insufficient autonomy while supervisors feel their guiding is not appreciated as teaching. These opinions are commonly grounded on general experiences and perceptions, instead of real-time supervisors' regulatory behaviors as procedures unfold. To close that gap, we captured and analyzed when and to what level supervisors award or restrain autonomy during procedures.

Twenty-Two-Year Outcome of Cartilage Repair Surgery by Perichondrium Transplantation.

Objective: The main purpose of the present study was to assess the risk for major revision surgery after perichondrium transplantation (PT) at a minimum of 22 years postoperatively and to evaluate the influence of patient characteristics.

Design: Primary outcome was treatment success or failure. Failure of PT was defined as revision surgery in which the transplant was removed, such as (unicondylar) knee arthroplasty or patellectomy.

Effect of ACL Reconstruction on Range of Tibial Rotation: A Systematic Review of Current Literature and a Recommendation for a Standard Measuring Protocol.

Background: Tibial rotation is an important topic in anterior cruciate ligament (ACL) surgery, and many efforts are being made to address rotational stability. The exact role of the ACL in controlling tibial rotation in clinical studies is unknown.

Purpose: To quantify the effect of ACL reconstruction on the amount of tibial rotation based on the current available literature.

Residents Think in the "Now" and Supervisors Think Ahead in the Operating Room. A Survey Study About Task Perception of Residents and Supervising Surgeons.

Objective: Progressive autonomous task performance is the cornerstone of teaching residents in the operating room, where they are entrusted with autonomy when they meet their supervisors' preferences. To optimize the teaching, supervisors need to be aware of how residents experience parts of the procedure. This study provides insight into how supervisors and residents perceive different tasks of a single surgical procedure.

Two-year recovery courses of physical and mental impairments, activity limitations, and participation restrictions after total knee arthroplasty among working-age patients.

Purpose: Total knee arthroplasty is increasingly performed on working-age individuals, but little is known about their recovery process. Therefore this study examined recovery courses of physical and mental impairments, activity limitations and participation restrictions among working-age total knee arthroplasty recipients. Associated sociodemographic and health-related factors were also evaluated.

Which patients improve most after total hip arthroplasty? Influence of patient characteristics on patient-reported outcome measures of 22,357 total hip arthroplasties in the Dutch Arthroplasty Register.

Background: Patient-reported outcome measures (PROMs) after total hip arthroplasty (THA), can be influenced by patient characteristics (case-mix factors). We used the Dutch Arthroplasty Register (LROI) to determine the effect of case-mix on improvement of PROMs after primary THA.

Methods: We included all primary THAs ( = 22,357) performed in the Netherlands between 2014 and 2018.

Recovery of strength after reduced pediatric fractures of the forearm, wrist or hand; A prospective study.

Introduction: The way strength recovers after reduction of pediatric fractures of the upper extremity has not previously been the specific scope of research. This is remarkable, since strength measurements are often used as an outcome measure in studies on trauma of the upper extremity. The aim of this study was to evaluate how strength recovers after sustainment of fractures of the forearm, wrist or hand treated by closed or open reduction in children and adolescents in the first 6 months after trauma.

The Supervisor's Toolkit: Strategies of Supervisors to Entrust and Regulate Autonomy of Residents in the Operating Room.

Objective: To identify what strategies supervisors use to entrust autonomy during surgical procedures and to clarify the consequences of each strategy for a resident's level of autonomy.

Background: Entrusting autonomy is at the core of teaching and learning surgical procedures. The better the level of autonomy matches the learning needs of residents, the steeper their learning curves.

Predictors for losing reduction after reposition in conservatively treated both-bone forearm fractures in 38 children.

Backgrounds: Alignment loss after reduction and cast immobilisation of angulated and/or complete displaced forearm fractures is challenging. Many authors have tried to describe risk factors and create indices (initial angulation, initial complete displacement, lack of anatomic reduction, cast and padding index) in order to identify those fractures that are prone to losing their alignment during treatment.

Methods: This retrospective case-control study included children sustaining both-bone forearm fractures treated by closed reduction and cast immobilisation.

The evolution of hand function during remodelling in nonreduced angulated paediatric forearm fractures: a prospective cohort study.

Forearm fractures are very common orthopaedic injuries in children. Most of these fractures are forgiving due to the unique and excellent remodelling capacity of the juvenile skeleton. However, significant evidence stating the limits of acceptable angulations and taking functional outcome into consideration is scarce.

Patient Characteristics Influence Revision Rate of Total Hip Arthroplasty: American Society of Anesthesiologists Score and Body Mass Index Were the Strongest Predictors for Short-Term Revision After Primary Total Hip Arthroplasty.

Background: Outcome and survival after primary total hip arthroplasty (THA) can be affected by patient characteristics. We examined the effect of case-mix on revision after primary THA using the Dutch Arthroplasty Register.

Methods: Our cohort included all primary THAs (n = 218,214) performed in patients with osteoarthritis in the Netherlands between 2007 and 2018.
