Noninvasive bracing of acromioclavicular joint dislocations is not superior to early functional rehabilitation and not inferior to surgical stabilization in Rockwood type III and V injuries.

Background: Treatment of acromioclavicular joint (ACJ) separations remains controversial. Yet, conservative treatment has become more common even for high-grade injuries. Available conservative treatment does currently however not address the loss of anatomical joint integrity in Rockwood (RW) III and V injuries.

Higher Accuracy of Arthroscopy Compared to MRI in the Diagnosis of Chondral Lesions in Acute Ankle Fractures: A Prospective Study.

Even after successful surgery for acute ankle fractures, many patients continue having complaints. A possible explanation is the presence of concomitant chondral lesions. The aim of this study is to investigate the accuracy of MRI compared to that of arthroscopy in the assessment of chondral lesions in acute ankle fractures.

Save the subchondral bone plate: Debridement versus bone marrow stimulation in acetabular cartilage defects over 60 months of follow-up.

Purpose: Bone marrow stimulation is a common treatment for full-thickness cartilage defects in the hip joint. However, common procedures may result in poor fibrous repair tissue and changes to the subchondral anatomy. This study investigated the clinical outcome of a cohort of International Cartilage Repair Society (ICRS) grades 3 and 4 cartilage defects treated with bone marrow stimulation compared to those who received simple debridement/chondroplasty.

Good mid- to long-term outcomes after meniscus bucket-handle tear repair: A comparative analysis with and without anterior cruciate ligament reconstruction.

Purpose: To evaluate mid- to long-term clinical outcomes after arthroscopic bucket-handle meniscal tear (BHMT) repair and to assess the impact of concurrent anterior cruciate ligament reconstruction (ACLR).

Methods: A comparative retrospective case series with blinded outcome assessment was conducted. All consecutive patients treated with arthroscopic BHMT repair with or without concurrent ACLR between 2001 and 2021 were eligible for inclusion.

Analyzing the reduction quality of the distal radioulnar joint after closed K-wire transfixation in a cadaver model: is supination or neutral position superior?

Introduction: Distal radioulnar joint (DRUJ) instabilities are challenging and their optimal treatment is controversial. In special cases or when reconstruction of the stabilizing triangular fibrocartilage complex (TFCC) fails, K-wire transfixation can be performed. However, no consensus has been reached regarding the rotational position of the forearm in which this should be done.

Significant improvements in clinical outcome measures and patient satisfaction after combined all-arthroscopic meniscal allograft transplantation and autologous chondrocyte implantation: A single-centre longitudinal study.

Purpose: The optimal treatment approach for the complex pathology of meniscal insufficiency and coexisting full-thickness cartilage defects remains unclear. The purpose of this study was to evaluate the viability, safety, and efficacy of this combined surgical approach at medium-term follow-up.

Methods: This is a single-centre longitudinal study with blinded outcome assessment.

K-Wire Osteosynthesis for Arthrodesis of the Paediatric Foot Is a Good and Valid Procedure.

Background: Foot deformities in children are common, and the majority can be treated conservatively. Nevertheless, there are deformities that require surgical treatment. These include rigid clubfeet, severe forms of pes planovalgus, pes cavus and several more.

Hook plate fixation of Neer type II distal clavicle fractures results in satisfactory patient-reported outcomes but complications and revisions are high.

Background: Surgical treatment of distal clavicle fractures Neer type II is challenging. A gold standard has not yet been established, thus various surgical procedures have been described. The purpose of this study is to report the radiological and clinical outcomes using hook plate fixation in Neer type II distal clavicle fractures.

Prospective Multicenter Randomized Controlled Trial of Surgical Versus Nonsurgical Treatment for Acute Rockwood Type 3 Acromioclavicular Injury.

Background: Evidence for the superiority of surgical versus nonsurgical treatment of Rockwood type 3 acromioclavicular joint (ACJ) dislocation is still lacking.

Hypothesis: It was hypothesized that surgical treatment will outperform nonsurgical treatment.

Study Design: Randomized controlled trial; Level of evidence, 1.

Revision of inlay resurfacing prosthesis with patellar realignment surgery and a new inlay prosthesis for persistent patellofemoral pain und patella subluxation.

We present the case of a 35-year-old patient who underwent inlay patellofemoral arthroplasty (I-PFA) followed by secondary patellar realignment surgery and inlay-to-inlay revision. Revision was performed because of ongoing pain, crepitation, and lateral subluxation of the patella. The original patella component (30-mm button) was replaced with a 35-mm dome, while the Hemi-Cap Wave (7 × 5 mm) I-PFA was replaced with the Hemi-Cap Kahuna (10 × 5 mm).

Long-Term Outcome and Athletic Level following Operative Treatment for Osteochondritis Dissecans of the Knee in Pediatric and Adolescent Patients.

Research on the long-term outcomes following surgical therapy for osteochondritis dissecans (OCD) of the knee is scarce. A single-center retrospective cohort study was conducted to investigate surgically treated patients for knee OCD between 1993 and 2007. A total of 37 patients with an average follow-up duration of 14 years (range 8-18) were in the final cohort.

High return to sport rate and good patient-reported outcomes in recreational athletes following simple elbow dislocations.

Background: The purpose of this study was to investigate outcomes and return to sport metrics in recreational athletes who suffered simple elbow dislocations and were treated operatively or nonoperatively.

Methods: The study included patients between the ages of 16 and 65 who were recreational athletes and had experienced a simple elbow dislocation, with at least 2 years having passed since the injury. Patient-reported outcomes including Mayo Elbow Performance Score (MEPS), Subjective Elbow Value (SEV), Oxford Elbow Score (OES) and Visual Analog Scale (VAS) were collected.

High degree of consensus amongst an expert panel regarding focal resurfacing of chondral and osteochondral lesions of the femur with mini-implants.

Introduction: The rationale for the use of mini-implants for partial resurfacing in the treatment of femoral chondral and osteochondral lesions is still under debate. The evidence supporting best practise guidelines is based on studies with low-level evidence. A consensus group of experts was convened to collaboratively advance towards consensus opinions regarding the best available evidence.

Is there still a place for anatomic hemiarthroplasty in patients with high functional demands in primary, nonreconstructable proximal humeral fractures? A clinical and radiographic assessment.

Background: Vitality-threatening proximal humerus fractures often provide an indication for prosthetic treatment. We investigated the issue of how anatomic hemiprostheses perform in younger, functionally challenging patients with the use of a specific fracture stem and systematic tuberosity management in medium-term follow-up.

Methods: Thirteen skeletally mature patients with a mean age of 64 ± 9 years and a minimum follow-up of 1 year after primary open-stem hemiarthroplasty for 3- and 4-part proximal humeral fractures were included.

Analysis of the cost-efficiency of the vascular impulse technology (VIT) in the perioperative management of complex ankle fractures: results of a prospective randomised controlled trial.

Introduction: Posttraumatic swelling causes a delay in surgery, a prolonged hospital stay and a higher risk of complications. Thus, soft tissue conditioning following complex ankle fractures is of central importance in their perioperative management. Since the clinical benefit of VIT usage on the clinical course has been shown, it should now be investigated whether it is also cost-efficient in doing so.

Complications and revisions in anatomic and reverse short stem shoulder arthroplasty.

Introduction: One current trend in the field of shoulder arthroplasty is a design shift to shorter and metaphyseal fixed humeral stem components. The aim of this investigation is to analyze complications resulting in revision surgery after anatomic (ASA) and reverse (RSA) short stem arthroplasty. We hypothesize that complications are influenced by the type of prosthesis and indication for arthroplasty.

Vascular impulse technology versus elevation for reducing the swelling of upper and lower extremity joint fractures.

Soft-tissue conditioning due to posttraumatic oedema after complicated joint fractures is a central therapeutic aspect both pre- and postoperatively. On average, 6-10 days pass until the patient is suitable for surgery. This study compares the decongestant effect of vascular impulse technology (VIT) with that of conventional elevation.

Arthroscopic defect size measurement in osteochondral lesions of the talus underestimates the exact defect size and size measurement with arthro-MRI (MR-A) and high-resolution flat-panel CT-arthro imaging (FPCT-A).

Purpose: The size of osteochondral lesions of the talus (OLTs) is highly relevant for their treatment. In addition to intraoperative measurement of defect size, preoperative planning by means of magnetic resonance imaging (MRI) or computed tomography (CT) is crucial.

Methods: Four defects of different sizes and depths were created on the talar joint surface in 14 cadaver feet.

Morphologic Alterations of the Sternoclavicular Joint following Ipsilateral Clavicle Fractures.

Rationale: To our knowledge, no study has investigated concomitant injuries of the sternoclavicular joint (SCJ) in acute clavicle fractures. The purpose of this study was to determine the effect of an ipsilateral clavicle fracture on the SCJ in a systematic computer tomography (CT) morphologic evaluation.

Methods: CT scans in the axial and coronal plane of 45 consecutive patients with clavicle fractures were retrospectively analyzed.

Patients with Small Acetabular Cartilage Defects Caused by Femoroacetabular Impingement Do Not Benefit from Microfracture.

Objective: According to current recommendations, large cartilage defects of the hip over 2 cm are suggested to undergo autologous chondrocyte transplantation (ACT), while small defects should be treated with microfracture. We investigated if patients with small chondral defects of the hip joint (≤100 mm) actually benefit from microfracture.

Design: In this retrospective multicenter cohort study 40 patients with focal acetabular cartilage defects smaller than 100 mm and of ICRS grade ≥2 caused by femoroacetabular impingement were included.

Influence of Rigor Mortis on Tendon Mobility in an Animal Fresh Cadaver Model.

(1) Many biomechanical studies are performed using fresh frozen cadavers or embalmed specimens, although the biomechanical characteristics do not match the characteristics of in vivo tendons. Therefore, a fresh in vivo-like cadaver model has been introduced recently. As a limitation for studies with fresh cadavers, must be considered.

Effect of shape and size of supraspinatus tears on rotator cuff strain distribution: an in vitro study.

Background: The impact of the size and shape of a supraspinatus tear on the strain of the intact rotator cuff and the kinematics of the shoulder is still unknown. This, however, can be relevant when deciding whether surgical reconstruction is required to prevent an increase in a tendon defect. In this study, the effect of tear width and shape on rotator cuff strain and glenohumeral kinematics was evaluated during active abduction.
