Trends of Ankle Arthroscopy in Italy: Analysis of an official National Database.

OBJECTIVES: Ankle arthroscopy has become increasingly popular as a less invasive surgical diagnostic and therapeutic procedure for a variety ankle disorder previously managed with open surgery. Despite literature reports encouraging outcomes and low complication rates, nationwide trends in ankle arthroscopy have been poorly investigated. To fully understand the burden of an emerging surgical approach as well as helping to create global standards for the diagnosis and treatment of ankle diseases, this study aimed to evaluate the incidence and demographics of patients undergoing ankle arthroscopy in Italy from 2001 to 2016. METHODS: Data were obtained from the National Hospital Discharge Records (SDO) provided by the Italian Ministry of Health. The patient's age, gender, length of hospital stays, primary diagnosis, and primary procedure are among the anonymized data. Population data were obtained from the National Institute for Statistics (ISTAT). According to the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) ankle arthroscopy was defined by the following procedure code: 80.27. RESULTS: A total of 23,644 procedures were performed in Italy. The 25-29 and 30-34 age groups underwent this type of surgery at most. The majority of patients were males. The median length of hospital stay was 2.1 ± 2.3 days. Each year in Italy, this surgery costs an average of 2,133,401€ ± 342,143€. The main primary codified diagnoses were: "Contracture of joint, ankle and foot" (13.4%), "Articular cartilage disorder, ankle and foot" (8.6%), "Late effect of sprain and strain without mention of tendon injury" (7.5%) and "Other joint derangement, not elsewhere classified, ankle and foot" (6.4%). CONCLUSIONS: The present study evaluated the burden of ankle arthroscopy on the national health care system and the distribution of the main diseases requiring this type of surgery. Surgeons and policy makers can allocate healthcare resources more effectively and provide patients with high-quality care by having a better understanding of national practice patterns.

Halving of the meniscectomy rate and their costs in Italy: A 15-years period analysis.

PURPOSE: The purpose of this study was to determine the incidence and hospitalization trends of meniscectomy in Italy from 2001 to 2016. A secondary aim was to investigate the economic burden of the disease on the national healthcare system. METHODS: Data were extracted from the Italian Ministry of Health's National Hospital Discharge Reports. Diagnoses are coded according to the ICD-9-CM. Meniscectomy was defined by the following main procedure codes: 806, 8026 and 8145. By dividing the number of annual cases by the size of the adult population reported annually by ISTAT, incidence rates were computed. RESULTS: Overall, 1,454,891 meniscectomies were performed in the study period between 2001 and 2016. The incidence was 178 procedures for every 100,000 Italian inhabitants. The incidence declined from 202 in 2001 to 106 in 2016. Males were the largest portion of patients undergoing surgery (68.2%). The average age of patients was 46.59 ± 15.07. A decreasing trend in length of hospital stay was observed over the study period. The annual average cost per 100,000 inhabitants was EUR 491.219 ± 122.148 with a range from EUR 291,500 ± 79.500 in 2016 to EUR 610,500 ± 166.500 in 2004. CONCLUSION: In Italy, the number of meniscectomies performed in the adult population has almost halved over the study period. Results of the present study in the Italian population seem to reflect how the clinical evidence basis affects surgical technique selection. The economic burden of meniscectomy is relevant in Italy with an estimated expenditure from EUR 181.861.375 to 318.257.406 between 2001 and 2016. LEVEL OF EVIDENCE: Level III.

Anxiety, Depression, and Quality of Sleep Vary in Their Correlation to Postoperative Outcomes of Rotator Cuff Repair: A Prospective Study.

Background/Objectives: Recent studies imply that psychological factors and sleep quality play a role in the outcomes of surgical procedures, including in orthopedic surgery. The aim of the present study is to evaluate possible correlations between preoperative depression, anxiety, and quality of sleep and functional 6-month postoperative scores in patients having undergone rotator cuff repair (RCR). Methods: All patients included in the study performed the Hospital Anxiety and Depression Scale (HADS) and Pittsburgh Sleep Quality Index (PSQI) questionnaires preoperatively and 36-item Short-Form Health Survey (SF-36), Oxford Shoulder Score (OSS), Shoulder Pain and Disability Index (SPADI), and PSQI questionnaires at the six-month postoperative follow-up. A total of 47 patients were included in the analysis. Results: Statistically significant differences between preoperative anxious and not-anxious groups were found in the postoperative SF-36 Physical Component Summary (PCS) and Mental Component Summary (MCS) scores and PSQI score. The correlation of the preoperative depression score to postoperative outcome measures revealed a strong positive correlation between the preoperative HADS-D score and the 6-month PCS, MCS, and OSS scores. The correlation of preoperative sleep quality to postoperative outcome measures revealed a strong positive correlation between the preoperative PSQI score and 6-month MCS score. Conclusions: Anxious patients had worse postoperative RCR outcomes. Depression may be influenced by factors related to RC pathology; however, there were no statistically significant correlations. Sleep quality generally improves postoperatively, and no significant association was found between bad preoperative sleepers and worse outcomes.

Bilateral simultaneous hip and knee replacement: an epidemiological nationwide study from 2001 to 2016.

BACKGROUND: Several studies have compared the pros and cons of simultaneous bilateral versus staged bilateral hip and knee replacement but the outcomes of these two surgical options remains a matter of controversy. This study aimed to evaluate demographic features, incidence and hospitalization rates of bilateral one stage total hip and knee arthroplasty in Italy. METHODS: The Italian Ministry of Health's National Hospital Discharge Reports (SDO) were used to gather data. This study referred to the adult population (+ 20 years of age) from 2001 to 2015 for hip arthroplasty and from 2001 to 2016 for knee arthroplasty. RESULTS: Overall, 1,544 bilateral simultaneous hip replacement were carried out. The incidence rate was 0.21 cases per 100,000 adult Italian residents. Male/female ratio was 1.1. The average days of hospital stay was 11.7 ± 11.8 days. The main primary codified diagnosis was: osteoarthrosis, localized, primary, pelvic region and thigh (ICD code: 715.15). 2,851 bilateral simultaneous knee replacement were carried out. The incidence rate was 0.37 cases per 100,000 adult Italian residents. Male/female ratio was 0.6. The average days of hospital stay was 7.7 ± 5.8 days. The main primary codified diagnosis was: osteoarthrosis, localized, primary, lower leg (ICD code: 715.16). CONCLUSIONS: The burden of hip and knee osteoarthrosis as a leading cause of bilateral joint replacement is significant in Italy. The national registers' longitudinal analysis may provide data for establishing international guidelines regarding the appropriate indications for one stage bilateral simultaneous hip or knee replacement versus two stage.

Epidemiology of Spondylolisthesis: A Nationwide Study From 2001 to 2016 in the Italian Population.

STUDY DESIGN: Epidemiological study. OBJECTIVE: This study aimed to evaluate the annual incidence of spondylolisthesis requiring surgery in Italy and the epidemiological characteristics of the patients. BACKGROUND: The health care system continues to incur considerable costs as a result of low-back pain. Segmental instability of the lumbar spine has attracted significant interest from researchers as a potential mechanism leading to mechanical low back pain. MATERIALS AND METHODS: The Italian Ministry of Health's National Hospital Discharge Reports database in the 2001-2016 period was considered. RESULTS: A total of 55,804 hospital admissions for spondylolisthesis were performed in Italy. The cumulative incidence was 6.8 interventions for every 100,000 Italian adult residents. The highest amount of procedures was recorded in the 65-69 years of age group. The overall patient's age was 56.8 ± 15.1 years. The 62.2% of patients were females. The average hospital stay length was 8.1 ± 7.3 days. On average, older patients require more days of hospital stay. Over the study period, it was observed a decreasing trend in the average number of days of hospital stay. The main primary diagnoses included were "acquired spondylolisthesis" [International Classification of Diseases (ICD) code: 738.4; 57.8%] and "spondylolisthesis" (ICD code: 756.12; 42.2%). By far, the main primary procedure performed was "lumbar and lumbosacral fusion of the anterior column, posterior technique" (ICD code: 81.08; 60.3%). CONCLUSIONS: Spondylolisthesis is a problem in Italy and a leading cause requiring spine surgery. Females were the majority of patients requiring surgery for spondylolisthesis. However, for younger age groups, males showed superior or equal need for spine surgery. The socioeconomic impact of spondylolisthesis in Italy is relevant, affecting patients still in the working population. The increasing trend of spine surgery for spondylolisthesis in Italy may be attributable to the widespread diffusion of modern diagnostic and surgical technologies. LEVEL OF EVIDENCE: Level II.

Evaluating the Minimum Clinically Important Difference and Patient Acceptable Symptom State for the Womac Osteoarthritis Index after Unicompartmental Knee Arthroplasty.

Patient-Reported Outcome Measures (PROMs) are standardized questionnaires that gather information on health-related quality of life directly from patients. Since a significant statistical mean change may not correspond to a clinical improvement, there is a need to calculate a considerable change in scores. This is done by the Minimum Clinically Important Difference (MCID) and Patient Acceptable Symptom State (PASS). The objective of this article is to report the MCID and the PASS values of the WOMAC (Western Ontario and McMaster University) osteoarthritis index for patients undergoing Unicompartmental Knee Arthroplasty (UKA). A total of 37 patients (25 females and 12 males; mean age 68 ± 8.1 years and mean BMI 28.7 ± 4) who underwent UKA were enrolled. All patients were assessed using the WOMAC and the Oxford Knee Score (OKS) questionnaires before and six months following the procedure. To measure the cut-off values for MCID, distribution methods and anchor methods were applied, while the PASS was assessed only via anchor approaches. The MCID related to the WOMAC average global score was 90.7 ± 7.6, the average pain dimension score was 93.2 ± 6.6, the average stiffness dimension score was 92.6 ± 17, and the average physical function dimension score was 89.7 ± 7.6. In terms of PASS, the normalized WOMAC was 82.8, the pain dimension was 87.5, the stiffness dimension was 93.7, and the functional dimension was 83.1. A 34.5 amelioration in the WOMAC score, from initial evaluation to final follow-up, using change in OKS > 5 as anchor, indicates that the patients' health state improved to a clinically significant degree. A value at least of 82.8 in WOMAC score after treatment denotes that the symptom state is deemed acceptable by most of the patients.

Magnetic resonance imaging could precisely define the mean value of tendon thickness in partial rotator cuff tears.

PURPOSE: Rotator Cuff (RC) lesions are classified in full-thickness and partial-thickness tears (PTRCTs). To our knowledge, no studies investigated the mean size of shoulder tendons in healthy and PTRCT patients using MRI scans. The aim of the study was to provide data to obtain and compare the mean value of tendon sizes in healthy and PTRCTs groups. METHODS: From 2014 to 2020, 500 were included in the study. They were divided into two groups: Group 1 (100 subjects) was composed of people positive for partial-thickness rotator cuff tears (PTRCTs), while the 400 subjects in Group 2 were negative for PTRCTs. RESULTS: Overall, of the patients included in the study, 231 were females and 269 were males. The mean age of the patients was 49 ± 12.7 years. The mean thickness of the supraspinatus tendon (SSP) was 5.7 ± 0.6 mm in Group 1, 5.9 ± 0.6 mm in Group 2 (p < 0.001). The mean length of the ISP tendon was 27.4 ± 3.2 mm in Group 1, 28.3 ± 3.8 mm in Group 2 (p = 0.004). The mean width of the SSP tendon was 17 ± 1.6 mm in Group 1, 17.6 ± 2 mm in Group 2 (p = 0.004). The mean width of the infraspinatus tendon (ISP) tendon was 17.7 ± 1.4 mm in Group 1, 18.3 ± 2.1 mm in Group 2 (p = 0.02). CONCLUSION: The anatomical data present in this paper may serve as a tool for surgeons to properly manage PTRCTs. The findings of the present study aimed to set the first step towards reaching unanimity to establish international cut-off values to perform surgery. Additionally, they could widely increase diagnostic accuracy, improving both conservative and surgical approaches. Lastly, further clinical trials using more accurate diagnostic MRI tools are required to better define the anatomical differences between PTRCT and healthy patients. LEVEL OF EVIDENCE: Level II, Retrospective Comparative Trial.

Preoperative and Postoperative Kinesiophobia Influences Postoperative Outcome Measures Following Anterior Cruciate Ligament Reconstruction: A Prospective Study.

The anterior cruciate ligament (ACL) is the most injured ligament of the knee, and the treatment of choice is usually ACL reconstruction. Kinesiophobia refers to an irrational and paralyzing fear of movement caused by the feeling of being prone to injury or reinjury. The aim of the present study is to evaluate the relationship between preoperative and postoperative kinesiophobia with postoperative outcomes of ACL-R evaluated through SF-36, ACL-RSI, KOOS, and OKS scores. Included patients all underwent ACL reconstruction. The preoperative TSK-13 questionnaire and six-month postoperative TSK-13, ACL-RSI, SF-36, KOOS, and OKS questionnaires were assessed in included patients. Normal distribution was assessed using the Shapiro-Wilk test. The study included 50 patients who filled out the questionnaires at the 6-month postoperative follow-up. Correlations between preoperative TSK-13 and postoperative outcome measures revealed a low-moderate negative correlation between preoperative TSK-13 and SF-36 PCS at 6-month follow-up. Correlations between postoperative TSK-13 and postoperative outcome measures revealed a high negative correlation between preoperative TSK-13 and ACL-RSI, KOOS Symptoms, KOOS Pain, KOOS ADL, and OKS at 6-month follow-up. Preoperative and postoperative kinesiophobia were found to influence postoperative ACL-R outcomes negatively, more specifically an increase in kinesiophobia showed a statistically significant correlation with worse postoperative SF-36 PCS scores in patients.

Minimal Clinically Important Difference (MCID), Substantial Clinical Benefit (SCB), and Patient Acceptable Symptom State (PASS) of the Shoulder Disability Questionnaire (SDQ) in Patients Undergoing Rotator Cuff Repair.

The Shoulder Disability Questionnaire (SDQ) is a Patient-Reported Outcome Measure (PROM) applied to evaluate shoulder surgery outcomes. The purpose of this study is to identify the accurate Minimal Clinically Important Difference (MCID), Substantial Clinical Benefit (SCB) and Patient Acceptable Symptom State (PASS) values for the SDQ score. A total of 35 patients (21 women and 16 men, mean age 76.6 ± 3.2 years) were followed up at 6 months postoperatively. To assess the patient's health satisfaction and symptoms, anchor questions were used. The MCID and SCB values of the SDQ score for patients who underwent arthroscopic rotator cuff repair from inception to final follow-up were 40.8 and 55.6, respectively. A change of 40.8 in the SDQ score at 6 months after surgery shows that patients achieved a minimum clinically important improvement in their state of health, and a 55.6 change in the SDQ score reflects a substantial clinically important improvement. The PASS cut-off of the SDQ score at 6 months postoperatively ranged from 22.5 to 25.8. If an SDQ score of 22.5 or more is attained after surgery, the health condition can be recognized as acceptable by the majority of patients. These cut-offs will help with understanding specific patient results and allow clinicians to personally assess patient improvement after rotator cuff repair.

Anxiety and Depressive Symptoms Correlated to Patient-Reported Outcome Measures after Rotator Cuff Repair: A Prospective Study in the Perioperative Period.

Anxiety and depressive symptoms adversely affect surgical outcomes in patients with rotator cuff tear (RCT) undergoing surgical repair. Patients without a diagnosis of mood disorders, such as anxiety and depression, before rotator cuff repair (RCR) can be considered an optimal candidate for surgery. The objective of this prospective observational study was to evaluate the relationship between anxiety and depressive symptoms, using the Hospital Anxiety and Depression Scale (HADS) as an assessment tool, and patient-reported outcome measures in RCT after repair surgery. This study included patients with RCT undergoing arthroscopic rotator cuff repair (RCR). Forty-three patients were included who had completed the HADS, Constant Murley Score (CMS), and Short Form Health Survey 36 (SF-36) questionnaires before surgery and in the postoperative follow-up, at 1 month, 3 months, and 6 months. The Friedman test showed that there were statistically significant changes in the different times point for HADS (p < 0.001), anxiety subscale of HADS, i.e., HADS-A (p < 0.001), depression subscale of HADS, i.e., HADS-D (p < 0.001), CMS (p < 0.001), and SF-36 (p < 0.001). The average scores of HADS, HADS-A, and HADS-D improved at each follow-up, showing improvement in discomfort. From the third month after surgery, there was an improvement in anxiety and depression disorders related to improved quality of life, functionality, and pain perception. The trend remained stable until the sixth month of follow up. This study shows that anxiety and depressive symptoms in RCT patients are significantly reduced after RCR with subsequent important improvements in terms of functionality, ability to carry out activities of daily living, perceived pain, and quality of life.

Colles' Fracture: An Epidemiological Nationwide Study in Italy from 2001 to 2016.

The present study aimed to evaluate the yearly number of Colles' fractures in Italy from 2001 to 2016, based on official information found in hospitalization records. A secondary aim was to estimate the average length of hospitalization for patients with a Colles' fracture. A tertiary aim was to investigate the distribution of the procedures generally performed for Colles' fractures' treatment in Italy. An analysis of the National Hospital Discharge records (SDO) maintained at the Italian Ministry of Health, concerning the 15 years of our study (from 2001 to 2016) was performed. Data are anonymous and include the patient's age, sex, domicile, length of hospital stays (days), primary diagnoses and primary procedures. From 2001 to 2016, 120,932 procedures for Colles' fracture were performed in Italy, which represented an incidence of 14.8 procedures for every 100,000 adult Italian inhabitants. The main number of surgeries was found in the 65-69- and 70-74-year age groups. In the present study, we review the epidemiology of Colles' fractures in the Italian population, the burden of the disease on the national health care system (in terms of length of hospitalization) and the distribution of the main surgical procedures performed for the treatment of the disease.

Have Elbow Arthroscopy Hospitalizations Decreased over the Years? An Epidemiological Italian Study from 2001 to 2016.

This study describes the trends of elbow arthroscopy in Italy and other countries in order to evaluate the yearly rates of EA. Its purpose is for future epidemiological studies to be able to compare their data between countries in order to understand the reasons for the increasing and decreasing trends. Data for this study were obtained from National Hospital Discharge records (SDO) at the Italian Ministry of Health (INHS). Data regarding sex, age, region of residence, region of surgery, length of hospitalization, and procedure codes were included. In total, 2414 elbow arthroscopies were performed in Italy from 2001 to 2016 in the adult population. The highest number of procedures was found in the 40-44 and 45-49 years age groups. Males represented the majority of patients undergoing EA both in total and over the years. An increase from 2001 to 2010 and a decrease from 2010 to 2016 were reported in the present analysis. According to other studies, males of 40-44 and 45-49 years age groups represent the most treated patients. Further epidemiological studies would provide data that could be compared between countries, reaching a general consensus on the best indications for this procedure.

Total Hip Replacement: Psychometric Validation of the Italian Version of Forgotten Joint Score (FJS-12).

BACKGROUND: One million Total Hip Replacements (THA) are thought to be performed annually. To measure prosthesis awareness throughout daily activities, the FJS-12 patient-reported outcome scale was developed. This article's goal is to undertake a psychometric validation of the Italian FJS-12 among a sample of related THA patients. METHODS: Between January and July 2019, data from 44 patients were retrieved. The participants were required to complete the Italian version of FJS-12 and of the WOMAC at preoperative follow-up, after two weeks, 1, 3, and 6 months postoperatively. RESULTS: The Pearson correlation coefficient between the FJS-12 and WOMAC was 0.287 (p = 0.002) at preoperative follow-up, r = 0.702 (p < 0.001) at 1 month, r = 0.516 (p < 0.001) at 3 months and r = 0.585 (p < 0.001) at 6 months. The ceiling effect surpassed the acceptable range (15%) for FJS-12 in 1 month (25.5%) and WOMAC in 6 months follow-up (27.3%). CONCLUSIONS: The psychometric validation of the Italian version of this score for THA was executed with acceptable results. FJS-12 and WOMAC reported no ceiling and floor effects. Therefore, to distinguish between patients who had good or exceptional results following UKA, the FJS-12 could be a reliable score. Under the first four months, FJS-12 had a smaller ceiling effect than WOMAC. It is recommended to use this score in clinical research concerning the outcomes of THA.

Establishing the Minimum Clinically Significant Difference (MCID) and the Patient Acceptable Symptom Score (PASS) for the Hospital Anxiety and Depression Scale (HADS) in Patients with Rotator Cuff Disease and Shoulder Prosthesis.

Insufficiently treated shoulder pain may cause mental disturbances, including depression and anxiety. The Hospital Anxiety and Depression Scale (HADS) is a patient-reported outcome measure (PROM) that aims to identify depression and anxiety in patients in nonpsychiatric wards. The aim of this study was to identify the minimum clinically important difference (MCID) and patient acceptable symptom state (PASS) scores for the HADS in a cohort of individuals with rotator cuff disease. Using the HADS, participants' degrees of anxiety and depression were assessed at inception and at their final assessment 6 months after surgery. To calculate the MCID and the PASS, distribution and anchor approaches were employed. The MCID from inception to final assessment was 5.7 on the HADS, 3.8 on the HADS-A, and 3.3 on the HADS-D. A 5.7 amelioration on the HADS score, 3.8 on the HADS-A, and 3.3 on the HADS-D, from inception to final assessment, meant that patients had reached a clinically meaningful improvement in their symptom state. The PASS was 7 on the HADS, 3.5 on the HADS-A, and 3.5 on the HADS-D; therefore, for the majority of patients, a score of at least 7 on the HADS, 3.5 on the HADS-A, and 3.5 on the HADS-D at final evaluation was considered a satisfactory symptom state.

Gender related results in total knee arthroplasty: a 15-year evaluation of the Italian population.

INTRODUCTION: This study aimed to estimate separately in women and men the number of Total knee arthroplasty (TKA) procedures performed in Italy from 2001 to 2016, exploring specific gender-related characteristics and trends. MATERIALS AND METHODS: Data of this study were collected from the National Hospital Discharge Reports (NHDR) reported at the Italian Ministry of Health in the years between 2001 and 2016. The information included in this archive are the patient's sex, age, the year when the surgical procedure was performed and the length of the hospitalization. RESULTS: Between the years 2001 and 2016, a total of 848,863 TKAs have been performed in Italy. TKAs in women passed from 20,719 in 2001 to 49,320 in 2016 showing an increase of 138%, while TKAs in men passed from 6631 in 2001 to 23,601 in 2016 showing an increase of 256%. From the age of 50 onwards, there was a prevalence of procedures in women, from 63.2% in the 50-54 group to 85.7% in the 100 + group. Conversely, under the age of 50, there was a higher percentage of surgeries performed in males, 57.1% on a total of 16,434 TKA surgeries carried out in this age group. CONCLUSIONS: This study showed that TKA is growing and heavily affecting the female population (70.6% of all TKAs) between 2001 and 2016. However, under 50 years old there was a higher percentage of surgeries performed in males (57.1%). The average number of days of hospitalization in females was higher than in males.

Metaphyseal cones and sleeves are similar in improving short- and mid-term outcomes in Total Knee Arthroplasty revisions.

PURPOSE: The purpose of this systematic review and metanalysis was to assess clinical and radiological outcomes of metaphyseal sleeves and cones and to identify their possible advantages and disadvantages. METHODS: A comprehensive search from the inception of the databases to March 2021 was performed on Medline, Scopus, CINAHL, Cochrane, Embase, Ovid, and Google scholar databases. Coleman Methodology Score was used for quality assessment. Author, year of publication, type of study, level of evidence, sample size, number of patients, number of knees treated, mean age, gender, mean follow-up, clinical outcomes, complications, the reason for revision and, type of prosthesis were extracted for analysis. Clinical studies providing data about patient's outcomes after the primary and Total Knee Arthroplasty revision with the usage of sleeves or cones and a minimum of 2 years of follow-up were included. RESULTS: The literature search and cross-referencing resulted in a total of 93 articles, but only 30 articles were appropriate for the systematic review. Comparable clinical results were reported between cones and sleeves. The meta-analysis showed a greater incidence of intraoperative fractures in patients treated with sleeves (1.6%, [95% CI 0.7; 3.4] in cones and 4.6%, [95% CI 3.3; 6.4] in sleeves, p = 0.01), while the risk of postoperative fractures (4.3%, [95% CI 2.7; 7] in cones and 2.1%, [95% CI 1.2; 3.5] in sleeves, p = 0.04) and infections (8.5%, [95% CI 6; 12] in cones and 3.7%, [95% CI 2.1; 7.3] in sleeves, p = 0.03) was higher with cones. CONCLUSION: A higher incidence of intraoperative fracture was reported in patients treated with sleeves, while a higher rate of postoperative fractures and infections was described in patients treated with cones. Nonetheless, complications were reported in both groups. LEVEL OF EVIDENCE: III.

Minimum Clinically Important Difference (MCID) and Patient Acceptable Symptomatic State (PASS) Applied to the SF-36 in Patients Who Underwent Arthroscopic Rotator Cuff Repair.

The 36-Item Short-Form Health Survey questionnaire (SF-36) is a reliable tool to assess the health-related quality of life of patients. If a mean difference between pre-operative evaluation and final follow-up is found to be statistically significant, then the change in score is not random. However, a statistically significant mean change may not correspond to a clinical amelioration for the patient or mean that the patient's state of health is to be considered acceptable. For this reason, interest in the concepts of minimal clinically important difference (MCID) and patient acceptable symptomatic state (PASS) has grown within recent years. The goal of the present work of research was to determine the MCID and PASS values for the SF-36 in patients who received rotator cuff repair (RCR). Forty-six patients (18 women and 28 men, mean age 58.5 ± 12.9) previously diagnosed with rotator cuff disease were enrolled. All of these patients underwent RCR. They were evaluated pre-operatively and six months after the surgical intervention as a final follow-up. The SF-36 questionnaire was assessed at each evaluation. The MCID cut-offs of the total, physical, and mental dimensions of the SF-36 for patients who underwent RCR were 23.1, 32.5, and 18.1, respectively. A 23.1 improvement in the SF-36 score at six months following RCR can be correlated with patients having reached a clinically significant improvement in health status. If 81.9 or more is attained in the SF-36 score after surgical repair, the symptom state can be judged as satisfactory by the majority of patients.

Humeral and Glenoid Version in Reverse Total Shoulder Arthroplasty: A Systematic Review.

There is increasing interest in reverse total shoulder arthroplasty (RTSA) as a reliable treatment for arthritic, rotator cuff deficient shoulders. Humeral and glenoid version are controversial parameters that can influence internal and external rotation, muscular forces, and implant stability as outcomes of RTSA. The aim of this study was to obtain an overview of the current knowledge on the effect of both humeral component version and glenoid component version and give recommendations on their most optimal degree for RTSA. A comprehensive quantitative review of the published literature on the effect of humeral version and glenoid version in RTSA was performed, to identify its influence on the range of movement, muscle forces, and intrinsic stability of the reverse prosthesis. Eleven studies were included: nine were biomechanical studies, one was a clinical-radiographic study, and one was an implant design consideration. Anterior stability can be improved by implanting the humeral component in neutral or with some anteversion. Glenoid component retroversion has been proven to reduce the likelihood of subluxation, while increasing ER and ROM at the same time. The study was conducted considering 5° anteversion; neutral; and 5°, 10°, and 20° retroversion of the glenoid component. Although a final opinion has not been yet expressed on the matter, the general consensus tends to agree on restoring 0° to 20° of retroversion of the humeral and glenoid component to yield the best outcomes.

Trends in Hospitalization and Economic Impact of Percutaneous Kyphoplasty in Italy.

Vertebral Fractures (VFs) caused by osteoporosis are the most typical reason for performing Percutaneous Kyphoplasty (PK). Globally, VF prevalence is not well described in the literature. In Europe, only Sweden has an accurate record of the incidence of this type of fracture. Moreover, the exact incidence of the PK procedure is not reported. Therefore, the annual patterns and financial burden of PK in Europe is not well known, and it could be may better understood by examining national registers. For surgeons, lawmakers, hospital administrators, and the healthcare system, determining the annual national costs of this treatment is helpful. The National Hospital Discharge Reports (SDOs) submitted to the Italian Ministry of Health during the years covered by this study (2009-2015) were used. A total of 13,113 kyphoplasties were performed in Italy, with a prevalence of 3.6 procedures for every 100,000 Italian inhabitants over 15 years. The average age of patients was 68.28 (±12.9). Females represented the majority of patients undergoing PK procedures (68.6%). The median length of hospital stay was 5.33 days. The prevalence of PK procedures increased from 2009 to 2015, while the average days of hospitalization decreased. Older patients were most at risk in undergoing PK procedures. Reporting the national data on PK in Italy could also help compare the findings across nations. The current study aims to determine the trends of PK hospitalisation and patient features in Italy.

Epidemiology of Pediatric Meniscectomy: A Nationwide Study in Italy from 2001 to 2016.

In the pediatric population, meniscectomy should be exceptional. This study aimed to estimate the incidence and trends of hospitalization of pediatric meniscectomy in Italy. Data were collected from the National Hospital Discharge Reports (SDO) reported at the Italian Ministry of Health. This study referred to the pediatric population (0-14 years of age) from 2001 to 2016. A total of 5188 pediatric meniscectomies were performed. The global incidence was 3.9 for every 100,000 Italian residents under 14 years of age. The most frequent age class was 10-14 years. The men/women ratio was 1.1. The average number of days of hospitalization was 1.8 ± 1.4. Men showed more days of hospitalization than women. The 5-9 age group presented the highest length of hospitalization (2.3 ± 1.5 days). The main primary codified diagnoses were as follows: derangement of the posterior horn of the medial meniscus, other derangement of the lateral meniscus, old bucket handle tear of the medial meniscus, and derangement of the lateral meniscus. Primary codified procedures were the excision of semilunar cartilage of the knee and knee arthroscopy. The burden of pediatric meniscectomy is relevant in Italy. The information required to develop global standards for managing pediatric meniscal lesions may be provided by conducting further epidemiological studies.
