This study aims to evaluate the outcomes of arthroscopic RCR using a single-row metallic anchor technique over a 12-year follow-up, focusing on patient-reported outcomes and potential risk factors. A monocentric cohort study was conducted on patients who underwent complete arthroscopic RCR with a single-row metallic anchor technique from January 2007 to July 2011.

Anterior Cruciate Ligament Reconstruction with LARS Synthetic Ligament: Outcomes and Failures.

Anterior cruciate ligament (ACL) injuries are common in athletes, but their prevalence has also increased among adults. ACL reconstruction (ACLR) is a key treatment option, with graft choice playing a critical role in recovery. The study evaluates the clinical and functional outcomes of ACLR using the Ligament Augmentation and Reconstruction System (LARS) in patients over 35 years old.

Residual Elbow Instability Treated with a Submuscular Internal Joint Stabilizer: Prospective and Consecutive Series with a Minimum Follow-Up of 12 Months.

: The management of residual elbow instability is a challenging and compelling issue for treating physicians. To overcome inherent drawbacks of dynamic external fixators, the internal joint stabilizer (IJS) has been developed, achieving successful results, but it can sometimes cause local tenderness or anesthetic concerns in the subcutaneous layer. In addition, a bulky anconeus can pull the hardware away from the axis of rotation with an increase in the lever arm and potential issues.

Revising Failed Reverse Total Shoulder Arthroplasty: Comprehensive Techniques for Precise Explantation of Well-Fixed Implants.

Background: With the increased utilization of reverse total shoulder arthroplasty (RTSA), there has been a corresponding increase in the incidence of and demand for revision RTSA. In cases in which the patient has undergone multiple previous surgeries and presents with well-fixed shoulder implants, even the most experienced shoulder surgeon can be overwhelmed and frustrated. Having a simple and reproducible treatment algorithm to plan and execute a successful revision surgery will ease the anxiety of a revision operation and avoid future additional revisions.

Nonunion of distal humeral fractures: Current concepts.

The incidence of complex articular fractures of the distal humeral in adults has increased and will be growing in the future due to the greater incidence of high energy trauma and to the higher percentage of elderly population. Successful treatment is challenging for the needed balance between a stability of often comminuted fracture and early motion. Nonunion is a common complication after distal humerus fractures that is influenced by a variety of factors such as biology, in particular the blood supply of the metaphysis, the non-anatomical reduction of the fracture, the methods of fixation, and mechanical failure.

Unexpected positive cultures of humeral head detected with dithiothreitol in primary shoulder arthroplasty.

Background: Unexpected positive cultures (UPCs) are frequently observed in primary shoulder arthroplasty, and its clinical significance has not yet been well defined. This study aimed to evaluate the UPCs in humeral head in primary shoulder replacement and to understand if UPCs increase in patients with risk factors for contamination (previous surgery or infiltrations).

Methods: Patients undergoing total shoulder replacement were enrolled in this prospective observational study.

Malunion of distal humeral fractures: Current concepts.

The incidence of complex articular fractures of the distal humeral in adults has increased and will be growing in the future due to the greater incidence of high-energy trauma and to the higher percentage of the elderly population. Successful treatment is challenging for the needed balance between the stability of often comminuted fractures and early motion. Malunion is a common complication after distal humerus fractures that is influenced by a variety of factors, such as biology, particularly the blood supply of the metaphysis, the nonanatomical reduction of the fracture, the methods of fixation, and mechanical failure.

Anatomical total shoulder arthroplasty revision to reverse shoulder arthroplasty using convertible glenoid: a systematic review of clinical and radiological outcomes.

Purpose: The aim of the present systematic review is to collect all the available evidence regarding the clinical and radiological results of revision to reverse shoulder arthroplasty (RSA) of modular anatomic shoulder prostheses (TSA) using a convertible metal-backed glenoid (MBG).

Methods: This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Studies investigating revision of TSA to RSA utilizing a convertible MBG and reporting clinical and radiological outcomes were identified.

The internal joint stabilizer for elbow instability: current concepts.

The management of residual elbow instability is challenging in both acute and chronic injuries. Among the available devices, the hinged external fixator provides an additional joint stabilization while allowing an early motion, but it is clumsy and associated to high rate of pin track complications. To address these issues, an internal joint stabilizer (IJS) has been recently developed.

Economic Evaluation of a Bioinductive Implant for the Repair of Rotator Cuff Tears Compared with Standard Surgery in Italy.

Introduction: Rotator cuff tear (RCT) is a painful, progressive condition resulting from damage to the rotator cuff tendons and is the leading cause of shoulder-related disability. Surgical repair of rotator cuff is an established standard of care (SOC); however, failure of the procedure can occur. In this context, the use of collagen-based bioinductive implant REGENETEN showed long-term improvements in clinical scores.

Arthroplasty as Primary Treatment for Metadiaphyseal Proximal Humerus Fractures: A Viable Alternative to Osteosynthesis for the Elderly.

Introduction: in the elderly patient population, where fracture comminution, osteoporotic fractures, and associated arthritis or rotator cuff pathologies dominate, metadiaphyseal proximal humeral fracture is a challenging subset of fractures to treat. This study reports on cementless long-stem reverse total shoulder arthroplasty (RTSA) as primary treatment of metadiaphyseal proximal humeral fractures in elderly patients.

Materials & Methods: Between January 2018 and October 2021, 22 consecutive patients sustained proximal humerus fractures with metadiaphyseal extension and underwent surgery with cementless long-stem RTSA.

Vancomycin powder embedded in collagen sponge decreases the rate of prosthetic shoulder infection.

Background: Shoulder arthroplasty is a successful procedure to treat degenerative and traumatic diseases of the glenohumeral joint. Periprosthetic infection represents an infrequent but dreaded complication (2%-4%). Application of intrawound vancomycin powder seems to reduce periprosthetic infections, but limited information is available on its efficiency in shoulder arthroplasty.

Reverse Total Shoulder Arthroplasty with a Cementless and Metaphyseal Stem Fixation Is a Viable Option for the Treatment of Proximal Humeral Fractures with Calcar Involvement.

Background: The purpose of the study was to evaluate the suitability of reverse total shoulder arthroplasty (RTSA) with a cementless and metaphyseal stem fixation as a treatment for complex proximal humeral fractures (PHFs) with a calcar fragment when this may be fixed with a steel wire cerclage. Clinical and radiographic outcomes were compared with the same RTSA for PHFs without a calcar fragment at a minimum of five-year follow-up.

Methods: A retrospective analysis was performed on acute PHFs "with a medial calcar fragment" (group A) and "without a calcar fragment" (group B) treated with a RTSA and cementless metaphyseal stem fixation.

Success of staged revision reverse total shoulder arthroplasty in eradication of periprosthetic joint infection.

Introduction: Management of periprosthetic joint infection (PJI) in shoulder arthroplasty remains a challenge, with no established gold standard treatment. This study presents the unique experience of a high-volume single-surgeon, single-institution approach on staged revision reverse total shoulder arthroplasty (RTSA) for infection. The authors theorize that staged revision RTSA is an effective treatment for PJI.

Does arthroscopic superior capsule reconstruction using porcine dermal xenograft represent a viable option in case of massive irreparable posterosuperior rotator cuff tear?

Introduction: The aim of the present study was to evaluate clinical and structural outcomes of patients with a massive irreparable rotator cuff tear treated with arthroscopic superior capsule reconstruction using an acellular porcine dermal xenograft. We hypothesized that this procedure would lead to improvement in clinical and functional results and that structural failure would not influence the final clinical results.

Materials And Methods: A retrospective analysis on arthroscopic superior capsule reconstruction performed from October 2016 to January 2019 was conducted.
