Suture button systems for coronoid fracture fixation: a biomechanical time-zero pilot study.

Purpose: This study aims to describe a fixation technique for coronoid fractures using suture buttons, and to biomechanically evaluate this technique in comparison to screw fixation as a time-zero pilot study.

Methods: An O'Driscoll type 2 anteromedial coronoid facet (AMCF) fracture was simulated in 20 fresh-frozen human elbows. The specimens were randomized into two groups and fracture fixation was performed with either a suture button system or a 3.

Minimum 10-Year Clinical and Functional Outcomes, and Return to Sport After Sternoclavicular Joint Reconstruction for Sternoclavicular Joint Instability.

Background: Sternoclavicular joint (SCJ) instability can lead to pain, reduced function, and an inability to perform sports and activities of daily living. Reconstruction of the SCJ using hamstring autograft in a figure-of-8 configuration has demonstrated good outcomes at short- and midterm follow-ups, but there is a paucity of literature on long-term outcomes.

Purpose: To evaluate the long-term clinical and functional outcomes after SCJ reconstruction, with a focus on return to sport, instability recurrence, and revision surgery.

Good functional outcome but high rates of instability recurrence after posterior open-wedge glenoid osteotomy for the treatment of posterior shoulder instability with increased glenoid retroversion at mid-term follow-up.

Purpose: To evaluate clinical, functional and radiological mid-term outcomes following posterior open-wedge glenoid osteotomy (POWGO) for the treatment of posterior shoulder instability (PSI) associated with increased glenoid retroversion.

Methods: Patients who underwent POWGO for the treatment of symptomatic PSI with glenoid retroversion >10° and participated in a previous study assessing short-term outcomes were included after a minimum follow-up of 5 years. Clinical (Rowe score and physical examination) and functional outcomes (Oxford Shoulder Instability Score [OSIS] and visual analogue scale [VAS] for pain) were assessed.

Orthopaedic surgery residents with a mentor report greater self-assessed theoretical and practical preparedness than residents without a mentor.

Purpose: The purpose of the study was to investigate the effect of mentorship on self-perceived theoretical and practical skill levels of German-speaking residents affiliated to a scientific society with a focus on sports medicine. It was hypothesized that orthopaedic surgery residents with a mentor would report higher subjective theoretical and practical skills and less apprehension towards performing surgeries unsupervised compared to those without mentors.

Methods: A 35-item questionnaire was distributed among resident members of AGA-Society for Arthroscopy and Joint-Surgery.

Outcomes of primary arthroscopic shoulder stabilization in active patients over 40-results at a mean follow-up of 7 years.

Background: The purpose of this study is to report clinical outcomes, return to activity, redislocation rate, and rate of conversion to arthroplasty for active patients over age 40 undergoing primary arthroscopic shoulder stabilization.

Methods: Patients over 40 years of age who underwent arthroscopic capsulolabral repair for shoulder instability between December 2005 and January 2018 with a minimum of 2-year postoperative follow-up were enrolled in this retrospective, monocentric study. Clinical outcome scores including the 12-Item Short-Form Survey, American Shoulder and Elbow Surgeons (ASES), Quick Disabilities of the Arm, Shoulder, and Hand, Single-Assessment Numeric Evaluation, and visual analog scale pain were collected.

Glenolabral Articular Disruption (GLAD) Is Not Associated with Worse Outcomes or Higher Instability Recurrence after Arthroscopic Bankart Repair-A Matched-Pair Analysis.

This study aimed to compare clinical outcomes and recurrence of instability after arthroscopic Bankart repair (ABR) in patients with anterior shoulder instability, with and without a GLAD lesion, while distinguishing between primary and recurrent instability. Consecutive patients who underwent isolated ABR between January 2012 and December 2021 were included. Patients with a concomitant GLAD lesion were matched in with patients without a GLAD lesion according to the following criteria: age, sex, BMI, follow-up time, and primary versus recurrent instability.

Sub-optimal therapy of patients with primary biliary cholangitis (PBC) in the real-life stetting of the German PBC cohort.

Real-world data on the management of patients with primary biliary cholangitis (PBC) are so far scarce in Germany. Therefore, we aimed to establish a nationwide registry and describe the clinical characteristics and therapy of PBC patients.Three different cohorts defined as ursodeoxycholic acid (UDCA) responders, as inadequate responders according to Paris II criteria, and as newly diagnosed patients were prospectively recruited.

Superior Capsular Reconstruction Using an Acellular Dermal Xenograft or Allograft Improves Shoulder Function but Is Associated with a High Graft Failure Rate.

The purpose of the present study was to evaluate clinical and functional outcomes, graft integrity rate and progression of osteoarthritis after superior capsular reconstruction (SCR) at short-term follow-up. Consecutive patients that underwent SCR using an acellular dermal xeno- or allograft between May 2018 and June 2020 for the treatment of irreparable posterosuperior rotator cuff tears were included. Shoulder function (American Shoulder and Elbow Surgeons [ASES] score), pain (Visual Analog Scale [VAS] for pain) and active shoulder range of motion (ROM) were evaluated preoperatively and after a minimum of 24 months postoperatively.

The impact of mental health conditions on clinical and functional outcomes after shoulder arthroplasty: a systematic review.

Background: Shoulder arthroplasty (SA) has been shown to improve quality of life, though outcomes may vary between individuals. Multiple factors may affect outcomes, including preoperative mental health conditions (MHCs). The goal of this systematic review was to evaluate the clinical and functional outcomes after SA in patients with MHC compared to patients without MHC.

Autonomic neuropathy in dialysis patients - investigations with a new symptom score (COMPASS 31).

Background: Symptoms of autonomic neuropathy (AN) are common in patients with diabetes and advanced renal disease. As yet different domains of autonomic neuropathy cannot be detected by a singular laboratory or invasive test. COMPASS 31, a new self-assessment test, has shown reliable results not only in cardiac autonomic neuropathy but also in different sub-domains when judging manifestation of AN by scores.

The impact of neurologic disorders on clinical and functional outcomes after shoulder arthroplasty: a systematic review.

Background: Patients with pre-existing neurologic disorders present a unique set of challenges for shoulder arthroplasty (SA) surgeons due to the presence of concomitant contractures, muscle weakness, and spasticity, which may affect outcomes and complication rates after SA. The goal of this systematic review was to evaluate the clinical and functional outcomes after SA in patients pre-existing with neurologic disorders, focusing on complication and reoperation rates.

Methods: This systematic review was performed in adherence to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines outlined by Cochrane Collaboration.

Malrotated lateral knee radiographs do not allow for a proper assessment of medial or lateral posterior tibial slope.

Purpose: The aim of this study was to investigate whether malrotation of lateral knee radiographs influences posterior tibial slope (PTS) measurements.

Methods: Lateral knee radiographs of all patients who underwent knee surgery at a single institution between June 2022 and January 2023 and received multiple lateral knee radiographs were included. Radiographs were categorised as malrotated lateral knee radiographs or lateral knee radiographs based on the radiographic distance between the medial and lateral posterior femoral condyles.

Females show worse functional outcome and quality of life compared to males 2 years after meniscus surgery: Data analysis from the German Arthroscopy Registry.

Purpose: The purpose of this study was to investigate the impact of sex on knee function, activity and quality of life following meniscus surgery using data from the German Arthroscopy Registry.

Methods: This is a retrospective cohort study with data collected between 2017 and 2022. Patient-reported outcome measures (PROMs), namely Knee Injury and Osteoarthritis Outcome Score (KOOS), EuroQol Visual Analogue Scale (EQ Scale), and Marx Activity Rating Scale (MARS), were collected preoperatively and at 6, 12 and 24 months postoperatively.

Varus osteotomy as a salvage procedure for young patients with symptomatic patellofemoral arthritis and valgus malalignment at short- to mid-term follow-up: a case series.

Purpose: The purpose of the study was to report the clinical, functional and radiological outcome following varus osteotomy as a salvage procedure in young to middle-aged patients with patellofemoral arthritis (PFA) and associated valgus malalignment. It was hypothesized that a significant improvement in knee function and reduction in pain would be achieved. Moreover, no conversion to patellofemoral joint arthroplasty could be observed.

Editorial Commentary: Bridging Graft Techniques Improve Short-Term Outcomes for Irreparable Rotator Cuff Tear Repair.

There is a growing need for nonarthroplasty treatment options for irreparable rotator cuff tears. Options include superior capsular reconstruction (SCR), tendon transfers, subacromial balloon spacer, bridge grafting, biological tuberoplasty, and partial rotator cuff repair with or without augmentation. In our experience, repair with marginal convergence techniques is superior to SCR; if there is enough tissue, repair is the preferred strategy.

The Posterior Tibial Slope Is Not Associated With Graft Failure and Functional Outcomes After Anatomic Primary Isolated Anterior Cruciate Ligament Reconstruction.

Background: Biomechanical studies have shown that an increased medial posterior tibial slope (MPTS) may affect anteroposterior knee laxity and tibial shear forces, ultimately increasing the risk for graft failure after anterior cruciate ligament (ACL) reconstruction. Previous clinical studies have, however, reported inconclusive results.

Purpose: The purpose of this study was to evaluate the relationship between the MPTS and graft failure as well as functional outcomes after anatomic primary isolated ACL reconstruction using a hamstring tendon autograft.

The Relationship between Supportive Care Needs and Health-Related Quality of Life in Cancer Patients.

The aim of this study was to analyze the relationship between quality of life (QoL) and supportive care needs (SCNs) in cancer patients. It is difficult to relate SCNs to detriments in QoL since SCNs and QoL assessment tools generally comprise different dimensions that cannot be directly related to each other. Therefore, we developed a short questionnaire with eight dimensions for uniformly measuring SCNs, QoL, and the subjective importance of these dimensions.

Pyrocarbon hemiprostheses show little glenoid erosion and good clinical function at 5.5 years of follow-up.

Background: The success of traditional shoulder hemiarthroplasty (HA) with cobalt-chromium heads is limited by painful glenoid erosion with problematic bone loss. Hemiprostheses with pyrolytic carbon (PyC) heads have shown reduced glenoid erosion in experimental laboratory studies. Few in vivo data are available.
