Unicompartmental knee arthroplasty implant survival in patients with borderline indications.

Introduction: In the literature, 80%-92% of patients are satisfied with their medial femorotibial unicompartmental knee arthroplasties (UKAs). These results are associated with a 10-year implant survival rates ranging from 94% to 98% in various studies. Such outcomes are generally reported after excluding patients with obesity, chronic anterior instability, frontal deformities, or preoperative knee flexion deformities exceeding 10 °.

Glenoid morphology variation between patients with hypermobile shoulder joints and controls: Identification of hyperlaxity-related morphologic bone changes.

Objective: Our study aims to quantitatively determine the concavity of the glenoid articular surface in patients with hypermobile shoulders compared to those without.

Method: We examined medical records of shoulder CTs from 2017 to 2022, selecting 50 patients with clinical signs of joint hypermobility for our case group and 54 for our control group. Two blinded readers independently assessed the glenoid morphology, calculating the glenoid concavity angle (GCA) and evaluating the articular surface shape as concave, flat, or convex.

New comprehensive score for predicting difficulties in revision total hip arthroplasty.

Background: Revision total hip arthroplasty (THA) can be complex, and assessing possible difficulties is important to predict the operative time. No simple score for predicting difficulties has been assessed prospectively. We therefore developed an original score for the pre-operative evaluation of extraction and reconstruction difficulties.

Quality of Preanesthesia Teleconsultation: The TELECAM Randomized Controlled Trial.

Preanesthesia teleconsultation helps reduce availability constraints as well as direct and indirect expenses. The TELECAM trial was performed to assess the quality of preanesthesia teleconsultation in terms of clinical parameters evaluation, feasibility, patient satisfaction and preoperative anxiety, and anesthesiologist satisfaction. TELECAM was an investigator-initiated, prospective, single-center, randomized, controlled, parallel group, evaluator-blinded, open-label study.

Improved Metastatic-Free Survival after Systematic Re-Excision Following Complete Macroscopic Unplanned Excision of Limb or Trunk Soft Tissue Sarcoma.

Background: Whether re-excision (RE) of a soft tissue sarcoma (STS) of limb or trunk should be systematized as adjuvant care and if it would improve metastatic free survival (MFS) are still debated. The impact of resection margins after unplanned macroscopically complete excision (UE) performed out of a NETSARC reference center or after second resection was further investigated.

Methods: This large nationwide series used data from patients having experienced UE outside of a reference center from 2010 to 2019, collected in a French nationwide exhaustive prospective cohort NETSARC.

Predictive factors of return-to-work trajectory after work-related rotator cuff syndrome: A prospective study of 96 workers.

Objective: Sustained return to work after surgery for work-related rotator cuff syndrome (WRRCS) remains quite difficult. The main purpose of the present study was to identify predictive factors of a return-to-work (RTW) trajectory.

Methods: A total of 96 workers with WRRCS were identified by 4 surgeons.

Overall survival in patients with re-excision of positive microscopic margins of limb and trunk wall soft tissue sarcoma operated outside of a reference center: a nationwide cohort analysis.

Background: This French nationwide NETSARC exhaustive prospective cohort aims to explore the impact of systematic re-excision (RE) as adjuvant care on overall survival (OS), local recurrence free survival (LRFS), and local and distant control (RFS) in patients with soft tissue sarcoma (STS) with positive microscopic margins (R1) after initial resection performed outside of a reference center.

Methods: Eligible patients had experienced STS surgery outside a reference center from 2010 to 2017, and had R1 margins after initial surgery. Characteristics and treatment comparisons used chi-square for categorical variables and Kruskall-Wallis test for continuous data.

Midterm results of pyrocarbon interposition shoulder arthroplasty: good outcomes after posttraumatic osteonecrosis without malunion of the tuberosities.

Background: In vitro data demonstrate the potential benefits of the pyrocarbon as a bearing material against cartilage or bone. And pyrocarbon-free interposition arthroplasty has been used with positive outcomes for over 10 years for hand and wrist joint replacements. This study reports the midterm results of a Pyrocarbon Interposition Shoulder Arthroplasty (PISA) in primary and secondary glenohumeral osteoarthritis and in avascular osteonecrosis.

CORIN KneeTec DeepDishTM: Functional outcomes after a follow-up of 12 months and comparison with the STRYKER Triathlon PS.

Several competing concepts of anteroposterior stabilization have been developed for total knee arthroplasty (TKA), with an overall great success despite some differences in terms of clinical or radiological outcomes. The CORIN KneeTec DeepDish TM is a novel mobile-bearing implant, stabilized with an ultra-congruent deep-dish poly- ethylene insert. The aim of the present study was to report clinical and radiological outcomes of a series of patients who received the KneeTec DeepDish TM after a follow-up of 12 months, and to compare them to those of a comparable series of patients who received the STRYKER Triathlon ® posterior- stabilized.

Validation of virtual reality arthroscopy simulator relevance in characterising experienced surgeons.

Background: Virtual reality (VR) simulation is particularly suitable for learning arthroscopy skills. Despite significant research, one drawback often outlined is the difficulty in distinguishing performance levels (Construct Validity) in experienced surgeons. Therefore, it seems adequate to search new methods of performance measurements using probe trajectories instead of commonly used metrics.

Clinical and Radiological Results of Hemiarthroplasty and Total Shoulder Arthroplasty for Primary Avascular Necrosis of the Humeral Head in Patients Less Than 60 Years Old.

Background: Total shoulder arthroplasty (TSA) and hemiarthroplasty (HA) have shown good clinical outcomes in primary avascular necrosis of the humeral head (PANHH) both in short and long terms. The purpose of this study was to assess the complications, the clinical and radiological outcomes of shoulder arthroplasty in young patients with PANHH.

Methods: One hundred and twenty-seven patients aged under 60 years old and suffering from PANHH were operated with arthroplasty.

Solitary bone tumor imaging reporting and data system (BTI-RADS): initial assessment of a systematic imaging evaluation and comprehensive reporting method.

Objectives: Identify the most pertinent imaging features for solitary bone tumor characterization using a multimodality approach and propose a systematic evaluation system.

Methods: Data from a prospective trial, including 230 participants with histologically confirmed bone tumors, typical "do not touch" lesions, and stable chondral lesions, were retrospectively evaluated. Clinical data, CT, and MR imaging features were analyzed by a musculoskeletal radiologist blinded to the diagnosis using a structured report.

Results of radial head prostheses implanted during Essex-Lopresti syndrome in multicentric study.

Aims: The aim was to evaluate the results of radial head prostheses (RHP) in Essex-Lopresti injury (ELI) and to compare results after RHP between acute and chronic ELI.

Patients And Methods: Thirty-one patients treated with RHP for ELI were selected from a multicenter retrospective series of 310 RHP, with follow-up greater than two years. Two groups were acute ELI group (n=19, average diagnosis = 5+/-9 days) and chronic ELI group (n=12, average diagnosis 8.

Added-value of advanced magnetic resonance imaging to conventional morphologic analysis for the differentiation between benign and malignant non-fatty soft-tissue tumors.

Objectives: To evaluate the added value of DWI, qualitative proton MR spectroscopy (H-MRS) and dynamic contrast-enhanced perfusion (DCE-P) to conventional MRI in differentiating benign and malignant non-fatty soft tissue tumors (NFSTT).

Methods: From November 2009 to August 2017, 288 patients with NFSTT that underwent conventional and advanced MRI were prospectively evaluated. The study was approved by the local ethics committee.

Virtual reality simulator improves the acquisition of basic arthroscopy skills in first-year orthopedic surgery residents.

Introduction: Arthroscopy training using a virtual reality (VR) simulator is said to improve the training of orthopedic surgery residents, although it has never been evaluated in a large representative population of first-year residents.

Hypothesis: We hypothesized that first-year residents who train on a VR simulator would improve their basic arthroscopy skills more than residents who use other training methods. The primary aim was to compare various arthroscopy-learning techniques after 6 months of training.

Proximal humeral bony adaptations with a short uncemented stem for shoulder arthroplasty: a quantitative analysis.

Background: Short uncemented stems have recently been proposed as an alternative to classic long stems for shoulder arthroplasty. The early results are promising, but bony adaptations of the proximal humerus have been reported. The aim of this study was to quantify these phenomena using the Ascend Flex stem and to determine the risk factors.

Denosumab-treated Giant Cell Tumors of Bone: A Clinicopathologic Analysis of 35 Cases From the French Group of Bone Pathology.

Denosumab, an antibody directed against receptor activator of nuclear factor-κB ligand (RANKL), has recently been introduced in the treatment strategy of giant cell tumor of bone. In this study, we assessed the tumor changes induced by denosumab in a national multicentric series of 35 cases (French Bone Pathology Group network-ResOs). Tissue specimens collected before and after denosumab treatment were investigated for RANKL, H3.

Surgical options for hallux rigidus: state of the art and review of the literature.

Hallux rigidus is a painful condition of the great toe characterized by restriction of the metatarsophalangeal range of motion and progressive osteophyte formation. Many etiologies have been postulated including excessive length of the first ray, trauma, abnormally elevated first metatarsal and a positive family history. However, most cases are likely idiopathic.

[Virtual reality simulation in orthopedics and trauma surgery in France : Current status and perspectives].

Introduction: The current reduction in working hours and the worldwide attempt to guarantee patient safety have led to significant changes in the training of surgical assistants. Numerous studies meanwhile present arthroscopic virtual reality (VR) simulators as very efficient tools for resident training.

Material And Methods: Based on a meta-analysis of VR arthroscopy simulators that identified different levels of evidence and validity, the situation in France in 2017/2018 is described in response to the new French law prohibiting access to the operating theater without prior simulator training.

Reverse shoulder arthroplasty for acute fractures in the elderly: is it worth reattaching the tuberosities?

Hypothesis: Reverse Shoulder Arthroplasty (RSA) may be indicated in displaced proximal humerus fractures in elderly patients. We hypothesized that tuberosity fixation and healing around the prosthesis would result in better outcomes and patient satisfaction.

Methods: Thirty-eight acute displaced or dislocated 3- and 4-part fractures in elderly patients were treated with reattachment of the tuberosities around a RSA.

Iliotibial band friction syndrome: An original technique of digastric release of the iliotibial band from Gerdy's tubercle.

The various surgical techniques to treat iliotibial band friction syndrome consist in releasing the iliotibial band by means of plasties that partially interrupt its continuity or by release of the deep aspect. We describe an original technique of digastric distal iliotibial band release from Gerdy's tubercle. Via a 2 cm approach above Gerdy's tubercle, the iliotibial band is incised longitudinally and partially released from the tubercle.
