Surgical anatomical landmarks for arthroscopic repair of subscapularis tendon tears. Clin Shoulder Elb 2024:cise.2023.01165. [PMID: 38738323 DOI: 10.5397/cise.2023.01165] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2023] [Accepted: 03/02/2024] [Indexed: 05/14/2024] Open
Abstract
Background Subscapularis repair has recently garnered significant interest. A thorough understanding of the tendon's anatomy is essential for precise and safe repair. Our objectives were to describe the anatomy of the subscapularis insertion, define its landmarks, and analyze nearby structures to guide arthroscopic repair. Methods We conducted an anatomical study, dissecting 12 shoulders. We evaluated the distance from the footprint to the axillary nerve, the dimensions, and shape of the footprint, and its relationship with the humeral cartilage. Results The distance to the axillary nerve was 32 mm (standard deviation [SD], 3.7 mm). The craniocaudal length of the footprint was 37.3 mm (SD, 4.6 mm). Its largest mediolateral thickness was 16 mm (SD, 2.2 mm), wider at the top and narrower distally. The distance between the footprint and the cartilage varied, being 3.2 mm (SD, 1.2 mm) in the upper part, 5.4 mm (SD, 1.8 mm) in the medium, and 15.9 mm (SD, 2.9 mm) in the lower part. Conclusions When performing a repair of the subscapularis tendon, the distance to the cartilage should be carefully evaluated as it varies proximally to distally, and the shape of the footprint (wider proximally, tapered distally) should be considered for implant positioning. The distance to the axillary nerve is approximately 30 mm. Anterior visualization guarantees direct control of all landmarks and allows accurate implant positioning with safe tendon release.

Abstract
Background The purpose of this study was to establish consensus statements via a Delphi process on the factors that should be included in a registry for those patients undergoing rotator cuff tear treatment. Methods A consensus process on the treatment of rotator cuff utilizing a modified Delphi technique was conducted. Fifty-seven surgeons completed these consensus statements and 9 surgeons declined. The participants were members of the European Society for Surgery of the Shoulder and Elbow committees representing 23 European countries. Thirteen questions were generated regarding the diagnosis and follow-up of rotator cuff tears were distributed, with 3 rounds of questionnaires and final voting occurring. Consensus was defined as achieving 80%-89% agreement, whereas strong consensus was defined as 90%-99% agreement, and unanimous consensus was defined by 100% agreement with a proposed statement. Results Of the 13 total questions and consensus statements on rotator cuff tears, 1 achieved unanimous consensus, 6 achieved strong consensus, 5 achieved consensus, and 1 did not achieve consensus. The statement that reached unanimous consensus was that the factors in the patient history that should be evaluated and recorded in the setting of suspected/known rotator cuff tear are age, gender, comorbidities, smoking, traumatic etiology, prior treatment including physical therapy/injections, pain, sleep disturbance, sports, occupation, workmen's compensation, hand dominance, and functional limitations. The statement that did not achieve consensus was related to the role of ultrasound in the initial diagnosis of patients with rotator cuff tears. Conclusion Nearly all questions reached consensus among 57 European Society for Surgery of the Shoulder and Elbow members representing 23 different European countries. We encourage surgeons to use this minimum set of variables to establish rotator cuff registries and multicenter studies. By adapting and using compatible variables, data can more easily be compared and eventually merged across countries.

High-resolution magnetic resonance imaging can predict osteoarthritic progression after medial meniscus posterior root injury: randomized in vivo experimental study in a rabbit model. J ISAKOS 2024:S2059-7754(24)00069-5. [PMID: 38583525 DOI: 10.1016/j.jisako.2024.03.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 03/25/2024] [Accepted: 03/29/2024] [Indexed: 04/09/2024]
Abstract
IMPORTANCE The field of meniscal root preservation has undergone significant advancement over the past decades; however, the challenge remains to fully understand whether meniscal root repair can ultimately arrest or delay osteoarthritic changes. OBJECTIVE To assess longitudinal changes in articular cartilage, subchondral bone, and progression to meniscal extrusion (ME) using high-resolution magnetic resonance imaging (MRI). METHODS Medial meniscus posterior root tear was surgically induced in 39 New Zealand white rabbits. Animals were randomly assigned into three experimental groups: partial meniscectomy after root tear (PM, n = 13); root tear left in situ (CT, n = 13); and transtibial root repair (RR, n = 13). Contralateral limbs were used as healthy controls. High resolution 4.7 Tesla MRI of the knee joint was performed at baseline, after 2-, and 4-months of post-surgery. Cartilage thickness was calculated in medial and lateral compartments. In addition, the evaluation of ME, subchondral bone edema and healing potential after root repair were assessed too. RESULTS Progressive cartilage thinning, ME, and subchondral bone edema were evident in all 3 study groups after 4-months of follow-up. The mean cartilage thickness in the PM group was 0.53 mm (±0.050), 0.57 mm (±0.05) in the CT group, and 0.60 mm (±0.08) in the RR group. The PM group exhibited significantly higher cartilage loss when compared to the CT and RR groups (p < 0.001). Moreover, progressive ME and subchondral bone edema were associated with a more severe cartilage loss at the final follow-up. CONCLUSION Meniscal root repair did not halt but rather reduced the progression of osteoarthritis (OA). Degenerative changes worsened at a rapid rate in the PM group compared to the RR and CT groups. Early cartilage swelling, persistent subchondral edema, and progressive ME predicted a more severe progression to knee OA in the CT and RR groups. LEVEL OF EVIDENCE II.

Effect of an algorithm for automatic placing of standardised test order sets on low-value appointments and attendance rates at four Spanish teaching hospitals: an interrupted time series analysis. BMJ Open 2024; 14:e081158. [PMID: 38267242 PMCID: PMC10824031 DOI: 10.1136/bmjopen-2023-081158] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Accepted: 01/11/2024] [Indexed: 01/26/2024] Open
Abstract
OBJECTIVE Reducing backlogs for elective care is a priority for healthcare systems. We conducted an interrupted time series analysis demonstrating the effect of an algorithm for placing automatic test order sets prior to first specialist appointment on avoidable follow-up appointments and attendance rates. DESIGN Interrupted time series analysis. SETTING 4 academic hospitals from Madrid, Spain. PARTICIPANTS Patients referred from primary care attending 10 033 470 outpatient appointments from 16 clinical specialties during a 6-year period (1 January 2018 to 30 June 2023). INTERVENTION An algorithm using natural language processing was launched in May 2021. Test order sets developed for 257 presenting complaints from 16 clinical specialties were placed automatically before first specialist appointments to increase rates of diagnosis and initiation of treatment with discharge back to primary care. PRIMARY AND SECONDARY OUTCOME MEASURES Primary outcomes included rate of diagnosis and discharge to primary care and follow-up to first appointment index. The secondary outcome was trend in 'did not attend' rates. RESULTS Since May 2021, a total of 1 175 814 automatic test orders have been placed. Significant changes in trend of diagnosis and discharge to primary care at first appointment (p=0.005, 95% CI 0.5 to 2.9) and 'did not attend' rates (p=0.006, 95% CI -0.1 to -0.8) and an estimated attributable reduction of 11 306 avoidable follow-up appointments per month were observed. CONCLUSION An algorithm for placing automatic standardised test order sets can reduce low-value follow-up appointments by allowing specialists to confirm diagnoses and initiate treatment at first appointment, also leading to early discharge to primary care and a reduction in 'did not attend' rates. This initiative points to an improved process for outpatient diagnosis and treatment, delivering healthcare more effectively and efficiently.

[Translated article] Latarjet procedure for shoulder instability: Implications in the innervation of the subscapularis muscle. Rev Esp Cir Ortop Traumatol (Engl Ed) 2024; 68:T1-T8. [PMID: 37981199 DOI: 10.1016/j.recot.2023.11.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Accepted: 01/01/2023] [Indexed: 11/21/2023] Open
Abstract
INTRODUCTION Our aim was to describe whether Latarjet's technique affects subscapularis muscle innervation. MATERIALS AND METHODS We studied 12 embalmed shoulders. Subscapularis muscle innervation pattern was registered. Dimensions of the subscapularis at the glenohumeral joint line and the nerves entry point were measured. Horizontal distances from the nerves to the glenohumeral joint line as well as vertical ones to the split were measured before and after Latarjet procedure. A safe zone for the split was designed to avoid damage to subscapularis innervation. RESULTS Subscapularis muscle is innervated by three principal branches: upper, middle, and inferior subscapularis nerves. No statistical differences were found between innervation distances before and after Latarjet procedure. To perform subscapularis split along the muscle safe zone, two thirds' proportions throughout all the split must be maintained. CONCLUSIONS Subscapularis muscle has a triple innervation and was not altered after Latarjet procedure. Therefore, Latarjet technique seems to respect subscapularis muscle innervation if its split is placed through the subscapularis muscle safe zone.

Abstract
BACKGROUND The role of arthroscopic Latarjet as a revision surgery after failed arthroscopic Bankart repair has yet to be established. PURPOSE To compare clinical outcomes, recurrences, and complication rates of arthroscopic Latarjet as a revision procedure after failed arthroscopic Bankart repair versus arthroscopic Latarjet as a primary procedure. DESIGN Cohort study; Level of evidence, 3. METHODS This is a retrospective study of prospectively collected data of patients who were diagnosed with anterior shoulder instability and underwent arthroscopic Latarjet stabilization between 2009 and 2018. Patients were separated into 2 groups depending on whether Latarjet was performed after a previous instability surgery (revision) or as a primary surgery (primary). Rowe score, Western Ontario Shoulder Instability Index (WOSI), Constant-Murley Shoulder Outcome (CMSO) score, and Single Assessment Numeric Evaluation (SANE) were assessed pre- and postoperatively with a minimum 24 months of follow-up. In addition, pre- and postoperative levels of sports activity, dislocations, subluxations, and complications were assessed. RESULTS A total of 97 patients (n = 62 revision; n = 35 primary), with a mean age of 31.0 ± 8.8 and 29.4 ± 7.6 years old in the revision and primary Latajet group, respectively, met the inclusion criteria. The mean follow-up in the revision group was 32 months (24-53) and 35.5 months (27.7-42.2) in the primary Latarjet group. No significant differences between groups were observed in Rowe score (revision = 91.4, primary = 94.1; P = .223), CMSO score (revision = 90.7, primary = 94; P = .105), and SANE (revision = 85.8, primary = 87.3; P = .683) postoperatively. However, the postoperative difference in the WOSI score between the revision and primary Latarjet groups was nearly significant (510 ± 334 vs 403 ± 343, respectively; P = .05). Four (6.4%) postoperative dislocations were reported in the revision and 1 (2.8%) in the primary Latarjet group (P = .14). Patients in the revision group had a lower return to the previous level of sports participation (P = .008) and decreased external rotation with the arm by the side compared with the primary Latarjet group (P = .000). CONCLUSION Arthroscopic Latarjet as a revision surgery is a reasonable surgical option in failed Bankart repair cases. The decision to perform arthroscopic Latarjet stabilization as a revision surgery should not be influenced by the potential risk of future complications as it provides comparable clinical outcomes to the primary Latarjet procedure with a low postoperative recurrence rate. However, a decreased level of postoperative sports participation and external rotation with the arm by the side can be expected.

Abstract
PURPOSE To compare clinical and radiological outcomes, implant survivorship at a minimum of 1-year follow-up using metaphyseal trabecular cones with or without impaction grafting in a complex revision TKA. METHODS A retrospective comparative matched analysis was performed and 15 patients who underwent revision surgery using the combination of porous trabecular metaphyseal cone and diaphyseal impaction grafting (MC-IBG) were matched with a group of 13 patients who also underwent revision surgery using metaphyseal cone (MC) without impaction grafting. All included patients presented severe bone defect (AORI 2,3) and a rotating-hinge prosthesis were implanted. RESULTS Both groups were comparable regarding the baseline demographic and clinical data. Patients had previously undergone a mean of 4 (range, 2-12) and 3 (range, 2-5) previous procedures in the MC-IBG and MC groups, respectively. The indications for revision were aseptic loosening in 11 (73.3%) and 11 (84.6%) patients; prosthetic joint infection in 4 (26.7%) and 2 (15.4%) in the MC-IBG and MC groups, respectively. There was no significant difference in the mean postoperative Knee Society Score between the study groups (p = 0.806). Overall, 4 patients had further revision. Two patients were revised in the MC-IBG group, one patient for aseptic loosening and the second one after 2 episodes of instability. Two patients in the MC group presented prosthetic joint infection and underwent a two-stage reimplantation. No significant difference was observed between the study groups at comparison (p = 0.92). CONCLUSION Trabecular metal cones with diaphyseal impaction grafting provide an alternative technique in a complex revision TKA surgery with early clinical and radiographic success.

Interobserver reliability of classifying shoulder calcific tendinopathy on plain radiography and ultrasound. Rev Esp Cir Ortop Traumatol (Engl Ed) 2023:S1888-4415(23)00263-1. [PMID: 38110150 DOI: 10.1016/j.recot.2023.12.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 11/22/2023] [Accepted: 12/11/2023] [Indexed: 12/20/2023] Open
Abstract
INTRODUCTION Shoulder calcific tendinopathy is a frequent cause of shoulder pain. Diagnosis is usually based on ultrasound (US) and/or X-ray. US is considered an inherently operator-dependent imaging modality and, interobserver variability has previously been described by experts in the musculoskeletal US. The main objective of this study is to assess the interobserver agreement for shoulder calcific tendinopathy attending to the size, type, and location of calcium analyzed in plain film and ultrasound among trained musculoskeletal radiologists. MATERIAL AND METHODS From June 2018 to May 2019, we conducted a prospective study. Patients diagnosed with shoulder pain related to calcific tendinopathy were included. Two different experienced musculoskeletal radiologists evaluated independently the plain film and the US. RESULTS Forty patients, with a mean age of 54.6 years, were included. Cohen's kappa coefficient of 0.721 and 0.761 was obtained for the type of calcium encountered in plain film and the US, respectively. The location of calcification obtained a coefficient of 0.927 and 0.760 in plain film and US, respectively. The size of the calcification presented an intraclass correlation coefficient (ICC) of 0.891 and 0.86 in plain film and US respectively. No statistically significant differences were found in either measurement. CONCLUSION This study shows very good interobserver reliability of type and size measurement (plain film and US) of shoulder calcifying tendinopathy in experienced musculoskeletal radiologists.

The importance of a structured failure analysis in revision acromioclavicular joint surgery: A multi-rater agreement on the causes of stabilization failure from the ISAKOS shoulder committee. J ISAKOS 2023; 8:425-429. [PMID: 37562575 DOI: 10.1016/j.jisako.2023.08.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2023] [Revised: 07/25/2023] [Accepted: 08/02/2023] [Indexed: 08/12/2023]
Abstract
BACKGROUND Acromioclavicular joint (ACJ) stabilizations are associated with a high overall failure rate with 9.5% of these patients requiring subsequent revision surgery. Consequently, understanding the specific cause of primary ACJ stabilization failure is paramount to improving surgical decision-making in this challenging patient cohort. PURPOSE To (1) identify risk factors and mechanisms for failure following primary arthroscopically-assisted ACJ stabilization to highlight the importance of conducting a detailed failure analysis and to (2) establish revision strategies based on real-life cases of primary failed ACJ stabilization. STUDY DESIGN Level of evidence IV. METHODS A survey was shared internationally among members of the International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine (ISAKOS) shoulder committee. The survey contained failure analysis of 11 real-life cases of failed primary arthroscopically-assisted ACJ stabilization. For each case, a thorough patient history, standardized radiographs, and CT scans were provided. Participants were asked to give their opinion on bone tunnel placement, cause of failure (biological, technical, traumatic, or combined), the stabilization technique used, as well as give a recommendation for revision. RESULTS Seventeen members of the ISAKOS shoulder committee completed the survey. Biological failure was considered the most common cause of failure (47.1%), followed by technical (35.3%) and traumatic (17.6%) failure. The majority deemed two modifiable factors (i.e., patient's profession and sport) as well as non-modifiable factors (i.e., patient's age and time from trauma to initial surgery) to be risk factors for failure. In 10 of 11 cases, the correct fixation device was used in the primary setting (90.9%; 52.8-82.4% agreement); however, in eight of those cases, the technique was not performed correctly (80.0%; 58.8-100% agreement). In 8 of all 11 cases, the majority recommended an arthroscopically assisted technique with graft augmentation for revision (52.9-58.8% agreement). CONCLUSION Biological failure and technical failure are the most common reason for failure in primary ACJ stabilization followed by traumatic failure. Besides, biological failure can be triggered by technical errors such as clavicular or coracoidal tunnel misplacement. Consequently, a detailed failure analysis including preoperative CT should be conducted on the causes of primary ACJ failure, and, if possible, an arthroscopically-assisted technique with graft augmentation should be prioritized in revision ACJ surgery. CLINICAL RELEVANCE ACJ stabilizations are associated with a high overall failure rate - potentially due to biological and technical properties. When encountering failed arthroscopically-assisted ACJ stabilization, a detailed failure analysis should be conducted on the causes of primary ACJ failure. Furthermore, an arthroscopically-assisted revision stabilization is feasible in most cases.

Abstract
Background The glenoid track concept is now widely accepted, and its evaluation is considered essential for making decisions about surgery. Purpose To define preoperative descriptive data and clinical and functional features in patients with anterior glenohumeral instability according to glenoid track status and to analyze the influence of off-track Hill-Sachs (HS) lesions on preoperative shoulder function. Study Design Case-control study; Level of evidence, 3. Methods Preoperative magnetic resonance imaging or computed tomography scans were used to measure the glenoid track. Descriptive data and preoperative objective and subjective clinical and functional features were compared between patients with on-track HS lesions versus off-track HS lesions. Multivariate regression analysis was conducted to identify potential risk factors for off-track HS lesion development. Results A total of 235 patients (201 men, 34 women; mean age, 29.6 ± 8.6 years) were included- 134 shoulders (57%) with on-track HS lesions and 101 shoulders (43%) with off-track HS lesions. Age <20 years at first dislocation, number of dislocations, and ≥2 years between first dislocation and surgery were significantly different between the study groups (P = .005, P = .0001, and P = .01, respectively). Regarding these characteristics, the odds ratios for the risk of developing an off-track lesion were 2.67 (95% CI, 1.2-5.99)-1.2 times higher for each additional instability episode (95% CI, 1.025-1.14) and 2.42 times higher (95% CI, 1.176-4.608) for patients whose first dislocation was ≥2 years before surgery, respectively. Patients with off-track HS lesions had a significantly greater degree of instability (P = .04), worse Rowe scores (48.8 ± 15.3 vs 54.8 ± 28.3 for on-track HS lesions; P = .04), and lower Western Ontario Shoulder Instability scores (975 ± 454 vs 1179 ± 428 for on-track HS lesions; P = .01). Conclusion Characteristics related to a history of instability (age <20 years at first instability episode, larger number of dislocations, ≥2 years between first dislocation and surgery) were found to be risk factors for the development of an off-track HS lesion in this study. Off-track lesions led to a higher degree of instability and worse objective and subjective preoperative shoulder function versus on-track HS lesions.

Abstract
PURPOSE/OBJECTIVE(S) New approaches are needed for frail or elderly patients with locally advanced head and neck squamous cell carcinoma (LA HNSCC) who are unfit to receive cisplatin with concurrent radiotherapy (RT). NBTXR3 is a first-in-class radioenhancer, composed of functionalized hafnium oxide nanoparticles, administered by a single intratumoral (IT) injection and activated by RT. NBTXR3 locally amplifies the anti-tumoral response of RT without adding toxicity to surrounding healthy tissue as shown in a randomized trial in soft tissue sarcoma. This two-part study: dose-escalation followed by the dose-expansion part reported here, evaluated the safety and preliminary efficacy for NBTXR3 activated by RT in elderly or frail patients ineligible to cisplatin. MATERIALS/METHODS This trial enrolled patients who had previously untreated AJCC 8th Stage III-IVA or T3, T4 SCC of the oral cavity or oropharynx (OPC) ineligible to cisplatin. Eligible patients received a single IT injection of NBTXR3 at the recommended dose (22% of the baseline tumor volume) followed by RT (IMRT 70 Gy in 35 fractions). The primary objectives of the dose expansion part were to test the recommended dose, to confirm its safety, and obtain preliminary evidence of efficacy. The secondary objectives included the evaluation of progression-free survival (PFS) and overall survival (OS). RESULTS Fifty-sixpatients in the dose expansion part were treated from April 2019-January 2022; 44 patients were evaluable for objective tumor response. In the all-treated population, median age was 71.9 years. 64.3% had age-adjusted Charlson Comorbidity Index scores ≥4, 55.4% had OPC (45.2% HPV+) and 80% had T3-4. Median injected volume of NBTXR3 was 13.6 [0.5-57.1] mL. Grade ≥ 3 adverse events reported as potentially related to NBTXR3 or to injection procedure were 1.2% and 0.4% of all AEs reported, respectively. In the evaluable population, the best objective response rate of the NBTXR3 injected lesion was 81.8% with a complete response rate of 63.6%. The best overall response rate (injected and non-injected lesions) was 79.5%. Final analyses on PFS and OS with long-term follow-up will be presented. CONCLUSION NBTXR3 IT injection followed by activation with RT was confirmed to be feasible and well tolerated in elderly or frail patients with LA HNSSC and significant comorbidities. The high rate of best overall response suggests that NBTXR3+RT is effective in this elderly population ineligible to cisplatin with a high unmet medical need. These results support our ongoing phase III study comparing NBTXR3/RT ± cetuximab vs. RT ± cetuximab in platinum-based chemotherapy ineligible elderly patients with LA-HNSCC: NANORAY 312 (NCIT04892173).

[PMID: 37749656 PMCID: PMC10518964 DOI: 10.1186/s41927-023-00362-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Accepted: 09/19/2023] [Indexed: 09/27/2023] Open
Abstract
OBJECTIVES Rheumatic and musculoskeletal diseases (RMDs) require a tailored follow-up that can be enhanced by the implementation of innovative tools. The Digireuma study aimed to test the feasibility of a hybrid follow-up utilizing an electronic patient reported outcomes (ePROs)-based monitoring strategy in patients with RMDs. METHODS Adult patients with rheumatoid arthritis (RA) and spondyloarthritis (SpA) were recruited for a 6-month bicentric prospective follow-up consisting of face-to-face and digital assessments. Patients were asked to report disease-specific ePROs on a pre-established basis, and could also report flares, medication changes, and recent infections at any time. Four rheumatologists monitored these outcomes and contacted patients for interventions when deemed necessary. Results from face-to-face and digital assessments were described. RESULTS Of 56 recruited patients, 47 (84%) submitted any ePROs to the digital platform. Most patients with RA were female (74%, median age of 47 years), while 48% of patients with SpA were female (median age 40.4 years). A total of 3,800 platform visits were completed, with a median of 57 and 29 visits in patients with RA and SpA, respectively. Among 52 reported alerts, 47 (90%) needed contact, of which 36 (77%) were managed remotely. Adherence rates declined throughout the study, with around half of patients dropping out during the 6 months follow-up. CONCLUSION The implementation of a hybrid follow-up in clinical practice is feasible. Digital health solutions can provide granular knowledge of disease evolution and enable more informed clinical decision making, leading to improved patient outcomes. Further research is needed to identify target patient populations and engagement strategies.

Abstract
BACKGROUND The optimal treatment option for meniscus root tears is still challenging, and whether the meniscus root repair ultimately can arrest or delay osteoarthritic changes is still a concern. PURPOSE/HYPOTHESIS The purpose of this study was 2-fold: (1) to describe and compare histopathologic findings of 3 different therapeutic options for medial meniscus posterior root tear: nonoperative management, partial meniscectomy, and meniscus root repair; and (2) to test the hypothesis that meniscus root tears treated nonoperatively predispose to a lower risk of osteoarthritic progression compared with partial meniscectomy. STUDY DESIGN Controlled laboratory study. METHODS Posteromedial meniscus root tears were carried out in 39 New Zealand White rabbits. Animals were randomly assigned into 3 experimental groups: partial meniscectomy after root tear (PM; n = 13), root tears treated conservatively (CT; n = 13), and transtibial root repair (RR; n = 13). Contralateral limbs were used as healthy controls. The animals were euthanized at 16 weeks postoperatively; tissue samples of femoral and tibial articular cartilage were collected and processed for macro- and microscopic assessment to detect signs of early osteoarthritis (OA). Each sample was histopathologically assessed using the Osteoarthritis Research Society International grading and staging system. RESULTS Osteoarthritic changes were the hallmark in all 3 experimental groups. The RR group had the lowest scores for cartilage damage (mean, 2.5; range, 2-3), and the PM group exhibited higher and more severe signs of OA (mean, 16; range, 9-16) compared with the CT group (mean, 5; range, 4-6). The between-group comparison revealed significant differences, as the PM group showed a significantly higher rate of macro- and microscopic osteoarthritic changes compared with the RR (P < .001) and CT (P < .001) groups. The weightbearing area of the medial femoral condyle was the most severely affected, and tidemark disruption was evident in all tissue samples. CONCLUSION Meniscus root repair cannot completely arrest the histopathologic progression of knee OA but leads to significantly less severe degenerative changes than partial meniscectomy and nonoperative treatment. Partial meniscectomy leads to the most severe osteoarthritic progression, while stable radial tears left in situ have lower progression compared with partial meniscectomy. CLINICAL RELEVANCE Histologic assessment is an essential tool and metric for guiding and understanding osteoarthritic features, providing insight into the disease development and progression. This study provides histopathologic evidence on osteoarthritic progression after medial meniscus posterior root repair. This knowledge can help to set more realistic expectations and can lead to the future development of augmented techniques.

[Translated article] Comparative biomechanical study of two configurations of cemented screws in a simulated proximal humerus fracture fixed with locking plate. Rev Esp Cir Ortop Traumatol (Engl Ed) 2023; 67:T263-T270.

Abstract
INTRODUCTION Screw tip augmentation with bone cement for fixation of osteoporotic proximal humerus fractures seems to improve stability and to decrease the rate of complications related to implant failure. However, the optimal augmentation combinations are unknown. The aim of this study was to assess the relative stability of two augmentations combinations under axial compression load in a simulated proximal humerus fractures fixed with locking plate. MATERIAL AND METHODS A surgical neck osteotomy was created in five pairs of embalmed humeri with a mean age of 74 years (range 46-93 years), secured with a stainless-steel locking-compression plate. In each pair of humeri, on the right humerus were cemented the screws A and E, and in the contralateral side were cemented screws B and D of the locking plate. The specimens were first tested cyclically in axial compression for 6000 cycles to evaluate interfragmentary motion (dynamic study). At the end of the cycling test, the specimens were loaded in compression force simulating varus bending with increasing load magnitude until failure of the construct (static study). RESULTS There were no significant differences in interfragmentary motion between the two configurations of cemented screws in the dynamic study (p=0.463). When tested to failure, the configuration of cemented screws in lines B and D demonstrated higher compression load to failure (2218N vs. 2105, p=0.901) and higher stiffness (125N/mm vs. 106N/mm, p=0.672). However, no statistically significant differences were reported in any of these variables. CONCLUSIONS In simulated proximal humerus fractures, the configuration of the cemented screws does not influence the implant stability when a low-energy cyclical load is applied. Cementing the screws in rows B and D provides similar strength to the previously proposed cemented screws configuration and could avoid complications observed in clinical studies.

Abstract
Cement removal during hip or knee arthroplasty revision is challenging and not exempt of complications. Cement-on-cement procedure is among techniques developed to safe removal of cement from bone, and it could be a realistic solution. This cement-on-cement devices can provide advantages in removing bone cement during hip and knee arthroplasty septic and non-septic revision surgeries, and can be regarded as an effective and safe alternative. We present our experience using the cement-on-cement technique in 34 cases between 2010 and 2021, including revision surgeries for 20 knee and 14 hip arthroplasties. In 3 out of 34 cases the technique failed, with a success of 91%. Mean surgical time was 2.77 (SD 0.93) hours and blood transfusion was required in 23 cases. Success was achieved in every aseptic case. Of all patients, 60% were septic cases. Infection was considered to be eradicated in 70% (14/20) of patients with a septic revision. Cement-on-cement is a safe and effective alternative for cement removal during hip and knee arthroplasty revision. Level of evidence: III, retrospective case series.

Comprehensive arthroscopic management without axillary nerve release or subacromial decompression achieves satisfactory and durable results in young patients with glenohumeral osteoarthritis. Knee Surg Sports Traumatol Arthrosc 2023:10.1007/s00167-023-07377-0. [PMID: 37130951 DOI: 10.1007/s00167-023-07377-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2022] [Accepted: 03/01/2023] [Indexed: 05/04/2023]
Abstract
PURPOSE The comprehensive arthroscopic management (CAM) procedure is a useful joint-preserving option for young or active patients with glenohumeral osteoarthritis (GHOA). Our objective was to evaluate the results and prognostic factors of the CAM procedure without direct axillary nerve release or subacromial decompression. METHODS A retrospective observational study among patients with GHOA who underwent the CAM procedure was conducted. Neither axillary nerve neurolysis nor subacromial decompression was performed. Both primary and secondary GHOA were considered; the latter was defined as a history of shoulder pathology (mainly instability or proximal humerus fracture). The American Shoulder and Elbow Surgeons scale, Simple Shoulder Test, Visual Analogue Scale, activity level, Single Assessment Numeric Evaluation, EuroQol 5 Dimensions 3 Levels, Western Ontario Rotator Cuff Index, and active range of motion (aROM) were analysed. RESULTS Twenty-five patients who underwent the CAM procedure met the inclusion criteria. After a mean follow-up of 42.4 ± 22.9 months, we found improvement (p < 0.001) in all postoperative values of the different scales. The procedure increased aROM overall. Patients with arthropathy due to instability showed worse results. The rate of CAM failures, defined as conversion to shoulder arthroplasty, was 12%. CONCLUSIONS This study showed that the CAM procedure without direct axillary nerve neurolysis or subacromial decompression might be a valid alternative in active patients with advanced GHOA to improve shoulder function (aROM and scores), decrease pain, and delay arthroplasty. This technique showed good subjective functional scores, high patient satisfaction, and a low rate of complications. LEVEL OF EVIDENCE IV.

Abstract
BACKGROUND Up to 50% of patients with uveal melanoma develop metastases (MUM) with a poor prognosis and median overall survival of approximately 1 year. METHODS This phase I study evaluated the safety, tolerability, pharmacokinetics, pharmacodynamics and efficacy of the oral protein kinase C inhibitor LXS196 in 68 patients with MUM (NCT02601378). Patients received LXS196 doses ranging from 100-1000 mg once daily (QD; n = 38) and 200-400 mg twice daily (BID; n = 30). RESULTS First cycle dose-limiting toxicities (DLTs) were observed in 7/38 (18.4%) QD and 2/17 (11.8%) BID patients. Hypotension was the most common DLT, occurring at doses ≥500 mg/day, and manageable with LXS196 interruption and dose reduction. Median duration of exposure to LXS196 was 3.71 months (range: 1.81-15.28) for QD and 4.6 months (range: 0.33-58.32) for BID dosing. Clinical activity was observed in 6/66 (9.1%) evaluable patients achieving response (CR/PR), with a median duration of response of 10.15 months (range: 2.99-41.95); 45/66 had stable disease (SD) per RECIST v1.1. At 300 mg BID, the recommended dose for expansion, 2/18 (11.1%) evaluable patients achieved PR and 12/18 (66.7%) had SD. CONCLUSION These results suggest manageable toxicity and encouraging clinical activity of single-agent LXS196 in patients with MUM.

Management of off-track Hill-Sachs lesions in anterior glenohumeral instability. J Exp Orthop 2023; 10:30.

Abstract
Bone loss has been identified as a risk factor for recurrent shoulder dislocations or failure after soft tissue repair. Although the range for "critical" bone loss is yet to be determined, glenoid and humeral bone defects should not be regarded as independent problems, but the interaction between them during shoulder motion should be evaluated as suggested by the glenoid track concept. The glenoid track concept is now widely accepted and considered essential for making decisions about surgery. Soft-tissue procedures usually work well in patients with on-track Hill-Sachs lesions but in off-track lesions do not. In this situation additional procedures should be performed.Different surgical options have been described to address off-track Hill-Sachs lesions, most commonly remplissage, Latarjet or free bone block procedures. Coracoid graft and free bone grafts convert the off-track Hill-Sachs lesion into on-track by lengthening the glenoid-track, whereas remplissage fill-in the humeral lesion so that it does not engage. In the setting of a Hill-Sachs lesion with little or no glenoid bone loss, remplissage has demonstrated satisfactory outcomes with a low complications and recurrence rate. Favorable results have been reported with glenoid bone grafting when managing isolated Hill-Sachs or bipolar lesions. Studies analyzing Latarjet and Eden-Hybinette procedures show that both procedures are safe and effective in the management of anterior glenohumeral instability. Attention should be paid to those patients with large bone defects not amenable to be restored with an isolated Latarjet that may be better addressed with an Eden-Hybinnete or adding a remplissage to the Latarjet procedure.

Abstract
In 2021, the Food and Drug Administration Oncology Center of Excellence announced Project Optimus focusing on dose optimization for oncology drugs. The Methodology for the Development of Innovative Cancer Therapies (MDICT) Taskforce met to review and discuss the optimization of dosage for oncology trials and to develop a practical guide for oncology phase I trials. Defining a single recommended phase II dose based on toxicity may define doses that are neither the most effective nor the best tolerated. MDICT recommendations address the need for robust non-clinical data which are needed to inform trial design, as well as an expert team including statisticians and pharmacologists. The protocol must be flexible and adaptive, with clear definition of all endpoints. Health authorities should be consulted early and regularly. Strategies such as randomization, intrapatient dose escalation, and real-world eligibility criteria are encouraged whereas serial tumor sampling is discouraged in the absence of a strong rationale and appropriately validated assay. Endpoints should include consideration of all longitudinal toxicity. The phase I dose escalation trial should define the recommended dose range for later testing in randomized phase II trials, rather than a single recommended phase II dose, and consider scenarios where different populations may require different dosages. The adoption of these recommendations will improve dosage selection in early clinical trials of new anticancer treatments and ultimately, outcomes for patients.

Abstract
BACKGROUND During recent years, the burden of bureaucracy in clinical research has increased dramatically, adversely impacting the activity of investigators and clinical research teams. Although compliance with the Declaration of Helsinki, the guidelines for Good Clinical Practice (GCP), and other applicable regulations remains unquestionable, their overinterpretation and substitution by the internal operating procedures of sponsors and Contract Research Organizations (CROs) have increased the administrative burden. A survey conducted by the European Society for Medical Oncology (ESMO) Clinical Research Observatory (ECRO) among 940 investigators confirmed that they considered that the administrative burden in clinical research is excessive; that administrative procedures could be reduced without affecting the safety and the rights of the patients and the quality of the data; and that bureaucracy represents an obstacle for clinical research. METHODS A panel of physicians with extensive experience in clinical research, composed by members of the ECRO and the ESMO Scientific Medical and Public Policy divisions, analyzed clinical trial procedures related to administrative workflow, pharmacovigilance, and medical care. RESULTS The panel identified situations that generate debate between investigators and sponsors/CROs and selected real clinical scenarios that exemplify such situations. The panel discussed and proposed specific recommendations for those situations, based on GCP. CONCLUSIONS This initiative aspires to streamline clinical research procedures and to become a platform for discussion among all clinical trial stakeholders, with the aim of promoting the sustainability of clinical research and the care of cancer patients.

Abstract
Latarjet modifies the anatomy of the shoulder, and subsequent revision surgery is challenging. It is mandatory to determine the cause of recurrence in order to select the best treatment option. A CT scan is needed to measure glenoid track and evaluate coracoid graft status: position, degree of consolidation, and osteolysis. Conservative management can be advocated in selected patients in whom the instability level does not interfere with the activities they wish to perform. Surgical treatment is based on the glenoid track measurement and coracoid graft suitability. The coracoid graft is considered suitable if it preserves the conjoint tendon insertion, does not show osteolysis, and is large enough to reconstruct the glenoid surface. Adding a remplissage is recommended for those cases with a coracoid graft insufficient to convert large off-track Hill-Sachs lesions into on-track. If the coracoid graft is suitable to reconstruct bone defects in terms of size and viability but is poorly positioned or avulsed, graft repositioning can be a valid option. In patients with unsuitable coracoid bone graft, free bone graft is the revision technique of choice. The size of the graft should be large enough to restore the glenoid surface and to convert any off-track Hill-Sachs lesion into on-track. There is a small group of patients in whom bone defects were properly addressed but Latarjet failed due to hyperlaxity or poor soft tissue quality. Extraarticular capsular reinforcement is suggested in this population.

Abstract
Abstract
Background
Poor self-care behaviour is associated with a higher risk of readmission and mortality in patients with heart failure (HF). The interplay between self-care and patient-reported outcomes such as health-related quality of life (QoL) has not been fully established.
Purpose
To describe the association between self-care and QoL in real-world cohort of HF patients.
Methods
We conducted an observational, prospective, cohort study of 1120 consecutive patients with chronic HF. We used the modified European Heart Failure Self-care Behaviour Scale 9-item version (EHFSCBS-9) to measure self-care. Scores were inverted and standardized (higher scores indicate better selfcare). To assess QoL, we used the Minnesota Living with Heart Failure Questionnaire (MLHFQ) (higher scores indicate worse QoL). Written informed consent, complete clinical and psychosocial information of patients were obtained at baseline. To determine the impact of global self-care and its dimensions (autonomy-based adherence, consulting behaviour and provider-based adherence), multivariate linear regressions models (backwards stepwise methods) to predict
QoL were constructed. The multivariate parametric and non-parametric associations between EHFSCBS-9 scoresand the β estimated risk of impairment of QoL (defined as MLHFQ scores ≥ median values) were explored using General Additive Models (GAM). All models were adjusted by age, sex and prognostic factors such as LVEF, NYHA, NT-proBNP levels and recent hospitalization among other well-known determinants of HF severity.
Results
A total of 484 patients (43%) were women, mean age was 72±11 years, and mean LVEF was 45±17%. Mean MLHFQ scores were 45±24. Mean EHFSCBS-9 scores were 69±28. There was a significant inverse correlation between EHFScBS-9 and MLHFQ scores (r=−0.158; p-value<0.0001). As shown in Table 1, self-care behaviour and its 3 domains were independent predictors of QoL in 7 out of the 16 associations explored. These models confirmed a weak linear relationship between EHFSCBS-9 scores and MLHFQ scores particularly between global selfcare and consulting behaviour dimension with global, emotional and social dimensions of QoL. Interestingly, when QoL was dichotomized as impaired/preserved QoL, GAM showed a significant non-parametric “U-shape” relationship (p-value<0.05) between EHFScBS-9 scores and the risk of impairment in QoL (Figure 1).
Conclusions
We have shown that self-care behaviour is an independent predictor of health related QoL in HF regardless the level of disease severity. Global self-care and consulting behaviour were particularly and significantly associated with global QoL and emotional and social dimensions of QoL. Interestingly the relationship between self-care scores and the risk of impaired global QoL was non-linear showing a “U-shape” association pointing out that patients with extreme levels of self-care were more likely to experience impairments in QoL.

Abstract
Background
Poor self-care behaviour is associated with a higher risk of readmission and mortality in patients with heart failure (HF). Psychosocial factors are key determinants of patient-reported outcomes (PROMs) such as health-realted quality of life (QoL). Little is known about the interplay between self-care and psychosocial factors on PROMs in HF.
Purpose
To describe the interaction of self-care and psycho-social factors on QoL in a real-world cohort of HF patients.
Methods
We conducted an observational, prospective, cohort study of 1120 consecutive patients with chronic. We used the modified European Heart Failure Self-care Behaviour Scale 9-item version (EHFSCBS-9) to measure self-care (inverted and standardised: higher scores indicate better self-care). To assess QoL, we used Minnesota Living with Heart Failure Questionnaire (MLHFQ) (higher scores indicate worse QoL). General linear models (GLM) were constructed to explore the interaction between psychosocial factors and poor self-care (defined as EHFSCBS-9 ≤lower tertile) on adjusted MLHFQ scores. To determine the impact of self-care, multivariate linear regressions models to predict QoL were constructed stratified according to selected psycho-social determinants. All models were adjusted by age, sex and psycho-social determinants of QoL including literacy, cognitive function (Pfeiffer test), dependency (Barthel and Lawton & Brody test), social support (Duke UNC and APGAR Familyfunction), depressive symptoms (15-item Geriatric Depression Scale) and fragility (Barber test scores ≥1).
Results
A total of 484 patients (43%) were women, mean age was 72±11 years, and mean LVEF was 45±17%. Mean MLHFQ scores were 45±24. Mean EHFSCBS-9 scores were 69±28. There was a significant inverse correlation between EHFScBS-9 and MLHFQ scores (r=−0.158; p-value <0.0001). Fragility was present in 883 patients (79%). In adjusted GLM, poor self-care (F=10.2; p-value=0.001) and fragility (F=17.9; p-value <0.001) were independent predictors of higher adjusted scores in the MLHFQ indicating worse QoL. As shown in Figure 1, the interaction between fragility and self-care was significant (F=6.8; p-value = 0.009). Linear regression models (Table 1) stratified according the absence (panel A) or the presence (panel B) of fragility showed that fragility modulated the association between self-care behaviour and QoL. Only in patients without fragility, self-care were independent predictors of QoL. On the other hand, in patients with fragility, self-care behaviour did not longer influence self-perceived health status in patients with HF.
Conclusions
We have shown that self-care behaviour is an independent predictor of PROMs in HF regardless the presence of important psycho-social determinants of QoL only when fragility status is taken into account. Fragility modulates the influence of self-care and QoL, including each one of its dimensions.

Methods
1120 patients with chronic HF from DAMOCLES study were analyzed. We used the modified European Heart Failure Self-care Behaviour Scale 9-item version (EHFSCBS-9) to measure self-care (inverted and standardised: higher scores indicate better self-care). To assess QoL, we used Minnesota Living with Heart Failure Questionnaire (MLHFQ) (higher scores indicate worse QoL). Cognitive function was evaluated using Mini-Mental State Examination (MMSE) and Short Portable Mental State Questionnaire (SPMSQ) Tests. Cognitive impairment was defined as abnormal age-and-literacy-adjusted scores. General linear models (GLM) were constructed to explore the interaction between cognitive function and poor self-care (defined as EHFSCBS-9 ≤lower tertile) on adjusted MLHFQ scores. To determine the impact self-care, multivariate linear regressions models to predict QoL were constructed stratified according to cognitive function. All models were adjusted by determinants of HF severity.
Results
Mean age was 72±11 years, 43% were women and mean LVEF was 45±17%. Lower MMSE scores (β=−0,163; p-value <0.001) and >3 errors in the SPMSQ indicating cognitive impairment (β=0.071; p-value = 0.023) were associated with higher scores in the MLHFQ. These associations were confirmed in multivariare linear regression models (β=0.062; p-value = 0.038). In adjusted GLM, poor global self-care (F=4.8; p-value = 0.029) was an independent predictor of higher adjusted scores in the MLHFQ. Interaction term poor self-care by cognitive impairment was significantly associated with MLHFQ scores (F=6.0; p-value=0.014; Figure 1). Multivariate linear regresion models (Table 1) stratified according the absence (panel A) or the presence (panel B) of cognitive impairment showed that cognitive function modulates the association between self-care behaviour and QoL. This effect was only seen in patients without cognitive impairment. In patients with cognitive dysfunction, self-care behaviour did not longer influence self-perceived health status in patients with HF.
Conclusions
Self-care behaviour is an independent predictor of PROMs in HF regardless cognitive disfunction. Cognitive function modulates 1) influence of global self-care and each one of its dimensions on emotional QoL and 2) impact of global self-care and consulting behaviour on global and social QoL.

Abstract
Abstract
Background
Poor self-care behaviour is associated with a higher risk in heart failure (HF). Gender is a determinant of patient-reported outcomes (PROMs) such as health-realted quality of life (QoL) in HF. Female gender is consistently associated with worse QoL. Whether gender may influence the effect of self-care on PROMS is not known.
Purpose
Describe the effect of self-care on QoL according to gender in a real world cohort of HF patients.
Methods
1120 patients with chronic HF were analysed. We used the modified European Heart Failure Self-care Behaviour Scale 9-item version (EHFSCBS-9) to measure self-care (inverted and standardised: higher scores indicate better self-care). To assess QoL, we used Minnesota Living with Heart Failure Questionnaire (MLHFQ) (higher scores indicate worse QoL). General linear models (GLM) were constructed to explore the interaction between gender and poor self-care (defined as EHFSCBS-9 ≤lower tertile) on adjusted MLHFQ scores. To determine the impact of global self-care and its dimensions, multivariate linear regressions models to predict QoL were constructed stratified according to gender. All models were adjusted by determinants of HF severity.
Results
Mean age was 72±11 years, 43% were women and mean LVEF was 45±17%. There was a significant inverse correlation between EHFScBS-9 and MLHFQ scores (r=−0.158; p-value<0.0001). Unadjusted MLHFQ scores were consistenly higher in women compared to men (49±23 vs. 43±24; p-value<0.001). In adjusted GLM, female gender (F=4.8; p-value=0.028) and poor global self-care (F=12.6; p-value<0.001) were independent predictors of higher adjusted scores in MLHFQ, indicating worse global QoL. As shown in Figure 1, the interaction term gender by poor self-care was not significantly associated with MLHFQ scores in adjusted GLM (F=0.018; p-value=0.893): the gap between women and men in terms of QoL was observed in both self-care strata and the effect of self care on QoL was observed in both genders. Multivariate linear regresion models (Table 1) stratified according to female gender (panel A) or male gender (panel B) showed that higher scores in the EHFScBS-9 were associated with lower scores in the MLHFQ in women and men. This effect (Table 1) was equally seen in both genders for global QoL and was driven by global self-care, consulting behaviour, and in a lesser extent by autonomy-baseda dherence. The physical dimension of QoL was not affected by self-care in either women or men except for consulting behaviour.
Conclusions
Self-care is an independent predictor of health-related QoL in HF, regardless of the level of disease severity. Global self-care, autonomy-based adherence and consulting behaviour were particularly associated with global QoL and emotional and social dimensions of QoL in women and men. In both genders, the effect of self-care on QoL was driven by its effect on emotional and social dimensions. Provider-based adherence did not influence QoL.

Isatuximab plus atezolizumab in patients with advanced solid tumors: results from a phase I/II, open-label, multicenter study. ESMO Open 2022; 7:100562. [PMID: 35987165 PMCID: PMC9588873 DOI: 10.1016/j.esmoop.2022.100562] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2022] [Revised: 07/08/2022] [Accepted: 07/11/2022] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND The anti-CD38 antibody isatuximab is approved for the treatment of relapsed/refractory multiple myeloma, but there are no data on its efficacy in solid tumors. This phase I/II study (NCT03637764) assessed the safety and activity of isatuximab plus atezolizumab (Isa + Atezo), an anti-programmed death-ligand 1 (PD-L1) antibody, in patients with immunotherapy-naive solid tumors: epithelial ovarian cancer (EOC), glioblastoma (GBM), hepatocellular carcinoma (HCC), and squamous cell carcinoma of the head and neck (SCCHN). PATIENTS AND METHODS Phase I assessed safety, tolerability, pharmacokinetics, pharmacodynamics, and the recommended phase II dose (RP2D) of isatuximab 10 mg/kg intravenously (i.v.) every week for 3 weeks followed by once every 3 weeks + atezolizumab 1200 mg i.v. every 3 weeks. Phase II used a Simon's two-stage design to assess the overall response rate or progression-free survival rate at 6 months (GBM cohort). Interim analysis was carried out at 6 months following first dose of the last enrolled patient in each cohort. Pharmacodynamic biomarkers were tested for CD38, PD-L1, tumor-infiltrating immune cells, and FOXP3+ regulatory T cells (Tregs) in the tumor microenvironment (TME). RESULTS Overall, 107 patients were treated (EOC, n = 18; GBM, n = 33; HCC, n = 27; SCCHN, n = 29). In phase I, Isa + Atezo showed an acceptable safety profile, no dose-limiting toxicities were observed, and RP2D was confirmed. Most patients experienced ≥1 treatment-emergent adverse event (TEAE), with ≤48.5% being grade ≥3. The most frequent TEAE was infusion reactions. The study did not continue to stage 2 based on prespecified targets. Tumor-infiltrating CD38+ immune cells were reduced and almost cleared after treatment. Isa + Atezo did not significantly modulate Tregs or PD-L1 expression in the TME. CONCLUSIONS Isa + Atezo had acceptable safety and tolerability. Clinical pharmacodynamic evaluation revealed efficient target engagement of isatuximab via treatment-mediated reduction of CD38+ immune cells in the TME. Based on clinical data, CD38 inhibition does not improve responsiveness to PD-L1 blockade in these patients.

Abstract
DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches. ProtoDUNE Dual Phase (DP) is a 6 × 6 × 6 m 3 liquid argon time-projection-chamber (LArTPC) that recorded cosmic-muon data at the CERN Neutrino Platform in 2019-2020 as a prototype of the DUNE Far Detector. Charged particles propagating through the LArTPC produce ionization and scintillation light. The scintillation light signal in these detectors can provide the trigger for non-beam events. In addition, it adds precise timing capabilities and improves the calorimetry measurements. In ProtoDUNE-DP, scintillation and electroluminescence light produced by cosmic muons in the LArTPC is collected by photomultiplier tubes placed up to 7 m away from the ionizing track. In this paper, the ProtoDUNE-DP photon detection system performance is evaluated with a particular focus on the different wavelength shifters, such as PEN and TPB, and the use of Xe-doped LAr, considering its future use in giant LArTPCs. The scintillation light production and propagation processes are analyzed and a comparison of simulation to data is performed, improving understanding of the liquid argon properties.

Abstract
Purpose To develop a predictable and reproducible model of knee osteoarthritis after medial meniscus posterior root release. Methods Posteromedial meniscal root tears were created in 12 White New Zealand rabbit knees. The contralateral limbs were used as healthy controls. The animals were euthanized at 16 weeks postoperatively; tissue samples of femoral and tibial articular cartilage were collected and processed for macro and microscopic analyses to detect signs of early degeneration. Clinical evaluation of the weight-bearing status on the affected knee was conducted at 0-, 4-, 8-, and 16-weeks postoperatively. Results Early and severe osteoarthritic changes were the hallmark and the main findings after 16-weeks post-surgery. Macroscopically, extensive osteoarthritic changes were observed across the femoral condyle and tibial plateau. Microscopic finding included ulcerations, fissures, fibrillations, pitting, and loss of the superficial layer. Cellularity was diminished, the normal pattern of distribution in columns was lost, and subchondral bone exposure was also evident. Conclusions This study describes a novel model of knee osteoarthritis that may guide the development of tailored interventions to delay or prevent knee osteoarthritis. This knowledge could shift the current treatment paradigm toward more conservative and knee salvageable treatment options and increase surgeons’ awareness of this injury pattern. Such considerations may have a positive impact on clinical decision-making and subsequent patient-reported clinical outcomes. Design Controlled laboratory study. Level of evidence II.

Subacromial Decompression in Patients With Shoulder Impingement With an Intact Rotator Cuff: An Expert Consensus Statement Using the Modified Delphi Technique Comparing North American to European Shoulder Surgeons. Arthroscopy 2022; 38:1051-1065.

Abstract
PURPOSE To perform a Delphi consensus for the treatment of patients with shoulder impingement with intact rotator cuff tendons, comparing North American with European shoulder surgeon preferences. METHODS Nineteen surgeons from North America (North American panel [NAP]) and 18 surgeons from Europe (European panel [EP]) agreed to participate and answered 10 open-ended questions in rounds 1 and 2. The results of the first 2 rounds were used to develop a Likert-style questionnaire for round 3. If agreement at round 3 was ≤60% for an item, the results were carried forward into round 4. For round 4, the panel members outside consensus (>60%, <80%) were contacted and asked to review their response. The level of agreement and consensus was defined as 80%. RESULTS There was agreement on the following items: impingement is a clinical diagnosis; a combination of clinical tests should be used; other pain generators must be excluded; radiographs must be part of the workup; magnetic resonance imaging is helpful; the first line of treatment should always be physiotherapy; a corticosteroid injection is helpful in reducing symptoms; indication for surgery is failure of nonoperative treatment for a minimum of 6 months. The NAP was likely to routinely prescribe nonsteroidal anti-inflammatory drugs (NAP 89%; EP 35%) and consider steroids for impingement (NAP 89%; EP 65%). CONCLUSIONS Consensus was achieved for 16 of the 71 Likert items: impingement is a clinical diagnosis and a combination of clinical tests should be used. The first line of treatment should always be physiotherapy, and a corticosteroid injection can be helpful in reducing symptoms. The indication for surgery is failure of no-operative treatment for a minimum of 6 months. The panel also agreed that subacromial decompression is a good choice for shoulder impingement if there is evidence of mechanical impingement with pain not responding to nonsurgical measures. LEVEL OF EVIDENCE Level V, expert opinion.

Abstract
BACKGROUND Unacceptably high rates of redislocation, reoperation, osteoarthritis, and coracoid nonunion have been reported in patients with a seizure disorder after surgery for shoulder instabilitiy. PURPOSE To evaluate the objective and subjective functional and radiologic results of the arthroscopic Latarjet procedure for anterior shoulder instability in patients with epilepsy and compare them with the results of patients without epilepsy. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A retrospective and comparative case-control analysis of patients operated for shoulder instability with arthroscopic Latarjet was conducted. Nineteen patients (21 unstable shoulders) with a seizure disorder (epilepsy group) were matched with 21 patients without a history of seizure (control group). Demographics, surgical indications, and imaging data were collected. Clinical outcomes at a minimum 2 years of follow-up (range, 2-9 years) postoperatively included Rowe score, Western Ontario Shoulder Instability Index (WOSI), Constant-Murley Shoulder Outcome (CMSO) score, and Single Assessment Numeric Evaluation (SANE). The incidence of complications, recurrent instability, redislocation, revision surgery, repeated seizure(s), and presence of osteoarthritis, coracoid nonunion, and osteolysis were also examined. RESULTS After a mean follow-up of 4.5 years, no significant differences in functional results were found between patients with and without epilepsy on the average Rowe (P = .917), WOSI (P = .621), CMSO (P = .600), and SANE (P = .859) scores. A total of 5 patients (7 shoulders) continued to have seizures postoperatively, but no seizure-related glenohumeral instability was documented. One dislocation and 1 subluxation were documented while participating in sports in each study group, comprising a recurrence rate of 9.5%, but no significant differences were found at comparison (P = .605). A bone defect did not influence the results, as no significant difference was found between the 2 groups. Osteoarthritic changes of the glenohumeral joint were observed in 5 shoulders (23.8%) in the epilepsy group and in 3 (14.3%) in the control group (P = .451). No case of coracoid nonunion or osteolysis was recorded. There was no statistically significant difference in postoperative athletic activity (P = .660). However, patients with epilepsy had significantly lower pre- and postoperative sports participation (P < .001). CONCLUSION Arthroscopic Latarjet stabilization can lead to improved functional and subjective outcomes and should be considered in patients with epilepsy with recurrent anterior glenohumeral instability. These results can be achieved regardless of the presence of bone defect and the postoperative control of seizures and are similar to those in patients without epilepsy.

Abstract
Introduction: Hip fractures affecting older people are at a higher risk of complications during the SARS-CoV-2 pandemic. The aim of this study is to provide data about proximal femoral fractures management and early outcomes during COVID-19 pandemic compared to the same period in 2019. Material and Methods: Retrospective and comparative study performed in two different periods were analyzed: from March 15, 2020, to April 30, 2020 (the first six weeks of Spain´s current confinement) and the same period in 2019. Data regarding demographics (age and sex, housing), type of fracture, surgical performance, early outcomes (at 30 days), and at 1-year follow-up were collected. A total of 146 patients were evaluated, 89 in 2019 and 57 in 2020. Results: Despite the drop ∼35.6% in hip fractures during SARS-CoV-2 period, distribution (age (P = 0.985), sex (P = 0.43), housing (P = 0.61), type of fracture (P = 0.41)) and Charlson comorbidity index (P = 0.12) were similar to a 2019 period. Surgical performance did not worsen in spite of the tough situation and the use of personal protective equipment, improving in some radiological variables (tip-to-apex and calcar reduction). In terms of postoperative outcomes, although there is a tendency to a short-term mortality increase (from 3.4% to 5.2%, P = 0.22), there were no differences at 1-year follow-up (20.2% in 2019 and 20.4% in 2020, P=0.587). In the same line, although in both groups the patients lost functionality at 1 year, there were no significant differences (P = 0.42). Conclusion: Even in challenging times, protocols and adequate organization ensure proper outcomes, reaching satisfying clinical and surgical outcomes during the COVID-19 pandemic, despite an increasing trend in short term mortality not seen at 1-year follow-up.

Abstract
Background The purpose of this study was to validate glenoid cartilage lesions as a negative prognostic factor and to define a new image-based preoperative evaluation method to identify surgical candidates for arthroscopic labral refixation with suture anchors in posterior shoulder instability. Methods Twenty-six patients who underwent arthroscopic posterior labral repair for shoulder instability were evaluated. Only patients with structural dynamic posterior instability were included. We evaluated on preoperative magnetic resonance arthrogram: glenoid version, humeral head subluxation, type of capsular insertion, and the cartilage lesions using the new Cartilage Wear Index (CWI). Two subgroups were analyzed with regard to the preoperative CWI and shoulder outcome scores: Single Assessment Numerical Evaluation (SANE) and Western Ontario Shoulder Instability Index (WOSI). Results The median age at operation was 28 (interquartile range = 21-33) years. Median overall postoperative outcome assessment demonstrated a SANE of 90 and a WOSI of 385. The median CWI was 1.02. Subgroup analysis revealed worse median WOSI and SANE scores in patients with a CWI >1.02 and a strong correlation between a high preoperative CWI and a higher postoperative WOSI score (R = 0.58; P = .038). Conclusion The CWI can be useful to identify patients who might obtain better outcomes when treated with arthroscopic labral repair in posterior shoulder instability.

Abstract
Background Multiple studies have reported an unacceptable implant-related complication rate in proximal humeral fractures treated with locking plates, particularly in older patients. Our objective was to compare the fracture fixation failure rates in elderly patients, after a dedicated technique for locking plate fixation with cement augmentation or without it. Methods A total of 168 open reduction and internal fixation with locking plates were performed for complex proximal humerus fractures by a single surgeon in 136 women and 32 men older than 65 years of age (average 76 years). Treatment groups included group 1 with noncemented screws (n = 90) and group 2 with cemented screws (n = 78). As per Mayo-FJD Classification, there were 74 (44%) varus posteromedial impaction, 41 (24%) algus impaction, 46 (28%) surgical neck, and 7 (4%) head dislocation injuries. A retrospective radiographic and a clinical analysis was performed. Results At a mean follow-up of 33 months, the implant failure rate was significantly lower in the cement augmentation group (1% vs. 8%, P = .03). The overall complication rate was 21% (25% group 1, 15% group 2; P = .1). Global avascular necrosis was associated with sustaining a valgus impacted fracture (P = .02 odds ratio 5.7), but not to augmentation. Partial avascular necrosis occurred only in patients treated with cemented screws (3.8%). The overall revision rate was 9% in both groups. Forward elevation was 126 ± 36 degrees and external rotation was 44 ± 19 degrees. The mean Constant score was 70 ± 15 in group 1 and 76 ± 15 in group 2 (P = .03). Conclusion Cement augmentation significantly decreased the rate of implant failure. Good results are expected for most patients treated with this technique.

Abstract
Introduction There is a paucity of comparative clinical data between arthroscopic all-inside end-to-end meniscal root suture and transtibial pullout technique in medial meniscus posterior root tears (MMPRT). Therefore, this study aimed to compare treatment failure, mid-term clinical and radiological outcomes of all-inside meniscus root repair versus the transtibial pullout technique and to analyze prognostic factors of postoperative clinical and radiological outcomes. Material and methods Forty-four patients were included in two therapeutic group: arthroscopic all-inside meniscal suture (MS: 13 knees) and transtibial pullout technique (TP: 31 knees).Primary clinical outcomes at a minimum of 27.2 months postoperatively included Knee injury and Osteoarthritis Outcome Score (KOOS) and Lysholm Knee Questionnare (LKQ). Radiographic assessment of the knee was performed to determine osteoarthritis severity using the Kellgren-Lawrence (KL) grading system.In addition, pre and postoperative MRI scans and intraoperative arthroscopic findings were recorded and the correlations between these findings, as outcome predictors and postoperative patients reported subjective outcome were assessed. Results No significant differences in postoperative KOOS and LKQ scores were found between the MS and TP group (p = 0.38 and 0.17, respectively).During follow-up one patients (7.7%) in the MS group and two (6.5%) in the TP group underwent total knee arthroplasty. The difference did not reach the statistical significance (p = 0.88).No differences were observed in postoperative MRI findings such as meniscal extrusion, osteochondral defect, chondromalacia patella, and bone morrow edema (p = 0.25, 0.97, 0.97, and 0.88, respectively).A univariate model revealed that the presence of postoperative meniscal extrusion; osteochondral defect; chondromalacia patella; increased BMI; age (>40 years) and longer time lapse between clinical onset to surgery (>6 months) were predictors of poor clinical outcome. The presence of meniscal extrusion, osteochondral defect and chondropatia patella portended worst postoperative outcomes in a multiple linear regression model. Conclusions It can be concluded that both techniques can reach good results when performed properly and if the injury pattern allows meniscal suture may be considered a treatment option for the management of MMPRT in well-selected patients.Patients with increased BMI, preoperative meniscal extrusion, chondromalacia patella, and osteochondral defect were at higher risk of poor clinical outcomes.

Abstract
BACKGROUND The Latarjet procedure is often used to address off-track Hill-Sachs lesions (OFF-HS) in shoulders with anterior instability. There are concerns as to whether the Latarjet procedure is able to convert all OFF-HS into on-track Hill-Sachs lesions (ON-HS) and whether this limitation could explain the cases of recurrent postoperative instability. HYPOTHESIS Latarjet surgery converts many preoperative OFF-HS lesions, but not all of them, and there is a difference in the failure rate between shoulders with converted lesions and those with persistent OFF-HS lesions. STUDY DESIGN Case series; Level of evidence, 4. METHODS Patients with anterior shoulder instability and an OFF-HS lesion treated with an arthroscopic classic Latarjet procedure between January 2010 and September 2017 were retrospectively evaluated. Patients with moderate or severe shoulder arthrosis, rotator cuff tears, or age older than 50 years were excluded. Glenoid track (GT), HS, HS interval (HSI), and the difference between HSI and GT (ΔHSI-GT) were measured preoperatively. A postoperative computed tomography scan and a clinical evaluation, including the Rowe and Western Ontario Shoulder Instability scores, were performed at a minimum 1- and 2-year follow-up, respectively. Postoperatively, 2 groups of patients were obtained: (1) patients with postoperative persistent OFF-HS; (2) patients with postoperative ON-HS. Clinical and imaging data were compared between the 2 groups. RESULTS A total of 51 patients (n = 51 shoulders), with a mean age of 29.8 ± 8.4 years (range, 15-50 years), met the inclusion criteria. Six shoulders (11.8%) still showed OFF-HS lesions despite Latarjet surgery. There were no postoperative dislocations, but 3 patients reported subluxations. The subluxation rate was significantly higher in the postoperative persistent OFF-HS group (2 [33%] vs 1 [2.2%]; P = .033). There was a wider preoperative HSI (29.8 ± 2.4 mm vs 22.9 ± 3.5 mm; P < .001) and a larger preoperative ΔHSI-GT (12.2 ± 3.8 mm vs 4.82 ± 3.2 mm; P < .001) in the persistent OFF-HS group. A receiver operating characteristic curve was performed based on preoperative ΔHSI-GT values. A preoperative ΔHSI-GT value ≥7.45 mm predicted a persistent OFF-HS after Latarjet surgery (sensitivity, 100%; specificity, 87%; positive predictive value, 50%; and negative predictive value, 100%). CONCLUSION Latarjet surgery converted many preoperative OFF-HS lesions into ON-HS lesions, but not all of them. Six patients (11.8%) retained an OFF-HS and had a statistically significantly higher failure rate after Latarjet surgery compared with those with postoperative ON-HS lesions. Because there were few postoperative OFF-HS lesions and few recurrences, findings are statistically fragile and should be confirmed with larger series.
