Abstract
BACKGROUND Reportedly, 17.2% of collegiate female gymnasts experience Achilles tendon ruptures (ATRs). Cumulative microtraumas resulting in chronic tendinopathy/tendinitis may contribute to this high injury risk. We hypothesized that the risk of ATRs in female collegiate gymnasts increases with years of competitive gymnastics, that non-steroidal anti-inflammatory drug (NSAID) use is associated with less ATRs, and that the risk is larger during competition than training. METHODS Female gymnasts from 78 USA collegiate teams completed a survey assessing the prevalence of ATRs, NSAID use, age at which competitive gymnastics started and age at which ATR occurred, and whether ATRs occurred during training or competition. RESULTS Twenty-one of 103 gymnasts (20.4%, 95% CI: 13.6% to 29.4%) experienced ATRs. Eighteen of 21 ruptures (85.7%, 95% CI: 61.3% to 95.8%) occurred after more than ten years of competitive gymnastics (mean: 14.0±2.6 years, 95% CI: 12.8 to 15.2 years). ATRs occurred 0.08±0.01 (95% CI: 0.06 to 0.11) times per 1000 hours at training versus 1.85±0.11 (95% CI: 1.60 to 2.10) times per 1000 hours at competition (P<0.05). Prevalence of NSAID use was 27.6% (95% CI: 18.6% to 39.0%) in gymnasts without ATR but only 5.5% (95% CI: 0.6% to 35.5%, P=0.09) in gymnasts with ATR. Multiple regression analysis demonstrated a negative association between NSAID use and incidence of ATRs (P<0.05). CONCLUSIONS Female collegiate gymnasts are at high risk for ATRs, especially after more than ten years of competitive gymnastics and during competition.

Epidemiology of insertional and midportion Achilles tendinopathy in runners: A prospective cohort study. JOURNAL OF SPORT AND HEALTH SCIENCE 2024; 13:256-263. [PMID: 36963760 PMCID: PMC10980873 DOI: 10.1016/j.jshs.2023.03.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/11/2022] [Revised: 02/05/2023] [Accepted: 02/24/2023] [Indexed: 05/12/2023]
Abstract
BACKGROUND Achilles tendinopathy (AT) is a common problem among runners. There is only limited evidence for risk factors for AT, and most studies have not defined the AT subcategories. No study has compared the incidence and risk factors between insertional AT and midportion AT, though they are considered distinct. This study aimed to assess incidence and risk factors of AT based on data from a large prospective cohort. The secondary aim was to explore differences in risk factors between insertional and midportion AT. METHODS Participants were recruited from among registered runners at registration for running events. Questionnaires were completed at baseline, 1 month before the event, 1 week before the event, and 1 month after the event. Information concerning demographics, training load, registered events, and running-related injuries were collected at baseline. The follow-up questionnaires collected information about new injuries. A pain map was used to diagnose midportion and insertional AT. The primary outcome was the incidence of AT. Multivariable logistic regression analysis was applied to identify risk factors for the onset. RESULTS We included 3379 participants with a mean follow-up of 20.4 weeks. The incidence of AT was 4.2%. The proportion of insertional AT was 27.7% and of midportion AT was 63.8%; the remaining proportion was a combined type of insertional and midportion AT. Men had a significantly higher incidence (5%, 95% confidence interval (95%CI): 4.1%-6.0%) than women (2.8%, 95%CI: 2.0%-3.8%). AT in the past 12 months was the most predominant risk factor for new-onset AT (odds ratio (OR) = 6.47, 95%CI: 4.27 -9.81). This was similar for both subcategories of AT (insertional: OR = 5.45, 95%CI: 2.51-11.81; midportion: OR = 6.96, 95%CI: 4.24-11.40). Participants registering for an event with a distance of 10/10.55 km were less likely to develop a new-onset AT (OR = 0.59, 95%CI: 0.36-0.97) or midportion AT (OR = 0.47, 95%CI: 0.23 -0.93). Higher age had a significant negative association with insertional AT (OR = 0.97, 95%CI: 0.94-1.00). CONCLUSION The incidence of new-onset AT among recreational runners was 4.2%. The proportion of insertional and midportion AT was 27.7% and 63.8%, respectively. AT in the past 12 months was the predominant risk factor for the onset of AT. Risk factors varied between insertional and midportion AT, but we could not identify clinically relevant differences between the 2 subtypes.

Patellar tendinopathy: an overview of prevalence, risk factors, screening, diagnosis, treatment and prevention. Arch Orthop Trauma Surg 2023; 143:6695-6705. [PMID: 37542006 PMCID: PMC10541843 DOI: 10.1007/s00402-023-04998-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Accepted: 07/18/2023] [Indexed: 08/06/2023]
Abstract
Patellar tendinopathy (PT), or jumper's knee, is an overuse injury that occurs in professional, as well as recreational, athletes. This condition is a noncontact injury, typically characterized by gradually increasing pain in the patellar tendon. It is prevalent in participants of several sports, but it occurs mostly in jumping sports. The diagnosis of PT is primarily clinical; however, imaging techniques can be useful as well. Risk factors differ between sexes, playing conditions, the kind of sport, playing level and personal characteristics. Screening is an essential tool to assess PT. This condition affects athletic performance and often persists for years. The use of preventative methods is imperative because of the persistence of this condition, especially in elite athletes who sometimes end their career after long and failed treatments. There are a wide variety of treatment and rehabilitation options available, the majority of which are non-operative, such as eccentric exercises, cryotherapy, platelet-rich plasma (PRP) injections, and anti-inflammatory strategies. If conservative treatment fails, surgery is the next most preferable step. Even though there are many surgical treatment methods, there is no clear evidence on what is the most effective approach to address PT. Taking this into consideration, as well as the extent of this clinical entity, novel therapeutic techniques, as well as screening and prevention methods, are expected to emerge in the near future.

Pairwise association of upper extremity musculoskeletal conditions: large population investigation from PERSIAN cohort study. J Orthop Surg Res 2023; 18:626. [PMID: 37633940 PMCID: PMC10463289 DOI: 10.1186/s13018-023-04108-6] [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: 07/09/2023] [Accepted: 08/17/2023] [Indexed: 08/28/2023] Open
Abstract
BACKGROUND People with one area of upper extremity musculoskeletal conditions (UEMSCs) may have other. We aim to determine how frequent is the ipsilateral coexistence of common UEMSCs apparent on interview and examination. METHODS This is a large population cross-sectional study conducted as part of the PERSIAN cohort study int Mashhad University of Medical Sciences (MUMS). The study aimed to evaluate individuals for symptoms and signs of the following conditions: carpal tunnel syndrome (CTS), lateral epicondylitis (LE), trapeziometacarpal osteoarthritis (TMC OA), DeQuervain's tendinopathy, trigger digit (TD), ganglion cyst, and rotator cuff tendinopathy (RCT). The primary outcomes of the study are (1) to determine the side-specific relative risk of each UEMSC coexisting with the second condition, and (2) to identify predictive factors of each UEMSC using side-specific multivariate logistic regression analysis. RESULTS We conducted a study involving 4737 individuals from the staff of MUMS and found significant pairwise associations among UEMSCs on a side-specific basis. Women had more chance of having DeQuervain's disease (β = 6.3), CTS (β = 3.5), ganglion cyst (β = 2.5), TMC OA (β = 2.3), and RCT (β = 2.0). Each condition (dependent variable) was associated with others (predictors) as follows: CTS: RCT (β = 5.9), TMC OA (β = 4.7), TD (β = 2.9), and LE (β = 2.5). TMC OA LE (β = 6.4), TD (β = 5.4), RCT (β = 4.3), and CTS (β = 4.1). LE: RCT (β = 8.1), TMC OA (β = 6.4), and CTS (β = 2.5). DeQuervain's disease: TD (β = 13.6), RCT (β = 4.5), and LE (β = 3.8). TD: CTS (β = 8.8), ganglion cyst (β = 7.6), DeQuervain's disease (β = 5.7), and TMC OA (β = 4.3). RCT: LE (β = 5.8), TMC OA (β = 5.5), CTS (β = 5.2), and DeQuervain's disease (β = 4.3). Ganglion cyst: TD (β = 4.8). CONCLUSION Our study reports significant increased frequency of the UEMSCs among patients who already have one of the diseases, in a large sample size study.

Diabetes mellitus tendino-myopathy: epidemiology, clinical features, diagnosis and management of an overlooked diabetic complication. Acta Diabetol 2022; 59:871-883. [PMID: 35291027 DOI: 10.1007/s00592-022-01860-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2022] [Accepted: 01/22/2022] [Indexed: 12/13/2022]
Abstract
Tendino-myopathy, an unexplored niche, is a non-vascular unstated T2DM complication, which is largely disregarded in clinical practice, thus, we aim to explore it in this review. Literature search using published data from different online resources. Epidemiologically, reported prevalence varies around 10-90%, which is marked variable and unreliable. Clinically, diabetic tendino-myopathy is typified by restriction of movement, pain/tenderness, cramps and decreased functions. Moreover, myopathy is characterized by muscle atrophy, weakness and ischemia, and tendinopathy by deformities and reduced functions/precision. In tendonapthy, the three most affected regions are: the hand (cheiroarthropathy, Dupuytren's contracture, flexor tenosynovitis and carpel tunnel syndrome), shoulder (adhesive capsulitis, rotator cuff tendinopathy and tenosynovitis) and foot (Achilles tendinopathy with the risk of tear/rupture), in addition to diffuse idiopathic skeletal hyperostosis. Pathologically, it is characterized by decreased muscle fiber mass and increased fibrosis, with marked extracellular matrix remodeling and deposition of collagens. The tendon changes include decreased collagen fibril diameter, changed morphology, increased packing and disorganization, with overall thickening, and calcification. Diagnosis is basically clinical and radiological, while diagnostic biomarkers are awaited. Management is done by diabetes control, special nutrition and physiotherapy, while analgesics, steroids and surgery are used in tendinopathy. Several antisarcopenic drugs are in the pipeline. This review aims to bridge clinical practice with research and update routine diabetic checkup by inclusion of tendino-myopathies in the list with an emphasis on management.

Risk Factor Analysis for Predicting the Onset of Rotator Cuff Calcific Tendinitis Based on Artificial Intelligence. COMPUTATIONAL INTELLIGENCE AND NEUROSCIENCE 2022; 2022:8978878. [PMID: 35449743 PMCID: PMC9017518 DOI: 10.1155/2022/8978878] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/05/2022] [Accepted: 03/31/2022] [Indexed: 12/19/2022]
Abstract
Background Symptomatic rotator cuff calcific tendinitis (RCCT) is a common shoulder disorder, and approaches combined with artificial intelligence greatly facilitate the development of clinical practice. Current scarce knowledge of the onset suggests that clinicians may need to explore this disease thoroughly. Methods Clinical data were retrospectively collected from subjects diagnosed with RCCT at our institution within the period 2008 to 2020. A standardized questionnaire related to shoulder symptoms was completed in all cases, and standardized radiographs of both shoulders were extracted using a human-computer interactive electronic medical system (EMS) to clarify the clinical diagnosis of symptomatic RCCT. Based on the exclusion of asymptomatic subjects, risk factors in the baseline characteristics significantly associated with the onset of symptomatic RCCT were assessed via stepwise logistic regression analysis. Results Of the 1,967 consecutive subjects referred to our academic institution for shoulder discomfort, 237 were diagnosed with symptomatic RCCT (12.05%). The proportion of women and the prevalence of clinical comorbidities were significantly higher in the RCCT cohort than those in the non-RCCT cohort. Stepwise logistic regression analysis confirmed that female gender, hyperlipidemia, diabetes mellitus, and hypothyroidism were independent risk factors for the entire cohort. Stratified by gender, the study found a partial overlap of risk factors contributing to morbidity in men and women. Diagnosis of hyperlipidemia, diabetes mellitus, and hypothyroidism in male cases and diabetes mellitus in female cases were significantly associated with symptomatic RCCT. Conclusion Independent predictors of symptomatic RCCT are female, hyperlipidemia, diabetes mellitus, and hypothyroidism. Men diagnosed with hyperlipidemia, diabetes mellitus, and hypothyroidism are at high risk for symptomatic RCCT, while more medical attention is required for women with diabetes mellitus. Artificial intelligence offers pioneering innovations in the diagnosis and treatment of musculoskeletal disorders, and careful assessment through individualized risk stratification can help predict onset and targeted early stage treatment.

Shoulder impingement: various risk factors for supraspinatus tendon tear: A case group study. Medicine (Baltimore) 2022; 101:e28575. [PMID: 35060519 PMCID: PMC8772690 DOI: 10.1097/md.0000000000028575] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Accepted: 12/22/2021] [Indexed: 01/05/2023] Open
Abstract
A total of 680 cases of monolateral shoulder pain and functional impairment were included, and Chi-Squared tests was incorporated to test for possible associations.No relation between impingement syndrome and potential risk factors was found, such as presence of down slopping (P = .083), presence of ossification acromiale (P = .102), presence of calcific tendinitis (P = .144), types of acromion (I [P = .600], II [P = .536], III [P = .633] and IV [P = .832]) and grade of acromioclavicular degenerative changes (mild [P = .077], moderate [P = .111], and severe [P = .700]). However, a significant relationship was uncovered between impingement syndrome and risk factors such as gender (X2 = 7.004, df = 1, P = .08) (where females were more prone), history of shoulder dislocation (X2 = 19.440, df = 1, P = .001), presence of supraspinatus tendon tear or tendinopathy (X2 = 69.344, df = 1, P = .001) and supraspinatus complete tear (X2 = 13.593, df = 1, P = .001). A significant relationship was found between the type of supraspinatus pathology and factors such as gender (female more prone) (X2 = 34.719, df = 3, P = .01), presence of down slopping (X2 = 57.765, df = 3, P = .01), history of shoulder dislocation (X2 = 148.880, df = 3, P = .001), type III of the acromion (X2 = 12.979, df = 3, P = .005), presence of acromioclavicular generative changes mild (X2 = 76.408, df = 3, P = .001) and moderate (X2 = 29.697, df = 3, P = .001), and acromiohumeral distance of ≤3 mm (X2 = 18.915, df = 3, P = .001), 3.1 to 6 mm (X2 = 13.212, df = 3, P = .004), and 9.1-12 mm (X2 = 15.066, df = 3, P = .002). Overall, the Magnetic Resonance Imaging results yielded high sensitivity for detecting full-thickness supraspinatus tears.Considering the findings, this study may help radiologists understand the salient risk factors and identify which factors are mainly responsible for supraspinatus tendon tears and the respective grade of tear (articular partial, bursal partial, complete, or tendinopathy).

Insertional Calcific Tendinopathy of the Achilles Tendon and Dysmetabolic Diseases: An Epidemiological Survey. Clin J Sport Med 2022; 32:e68-e73. [PMID: 32976122 DOI: 10.1097/jsm.0000000000000881] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2019] [Accepted: 05/30/2020] [Indexed: 02/02/2023]
Abstract
OBJECTIVE This study reports the incidence of insertional calcific tendinopathy (ICT) of the Achilles tendon in the general population and the percentage of symptomatic patients. The secondary aim is to ascertain whether ICT is associated with diabetes mellitus, thyroid disorders, obesity, and hypercholesterolemia. We hypothesized that metabolic diseases increase the risk of ICT of the Achilles tendon. DESIGN Prospective observational study (level III study). SETTING Orthopedic Outpatients Clinic and Emergency Department of Tor Vergata University Hospital, Rome, Italy. PARTICIPANTS Four hundred thirty-three subjects who met the inclusion criteria. INTERVENTION METHODS We collected the plain radiographs of the foot and ankle of patients who attended the hospital. Personal data were recorded [age, sex, and body mass index (BMI)], and comorbidities investigated (diabetes mellitus, hypothyroidism, hyperthyroidism, obesity, and hypercholesterolemia). Multivariate regression analyses were performed to study the predictors of the occurrence of Achilles ICT. RESULTS A total of 101 patients (23.3%) showed radiographic evidence of ICT, and 3% (13 patients) were symptomatic. Age [odds ratio (OR) 1.05], diabetes (OR 2.95), hypercholesterolemia (OR 2.27), and hypothyroidism (OR 3.32) were significantly associated with the presence of ICT of the Achilles tendon. Independent predictors of ICT were age, diabetes, hypercholesterolemia, and hypothyroidism. A BMI >30 was associated with a higher incidence of calcifications, and patients with 2 or more comorbidities had more than 10 times higher risk to develop ICT. CONCLUSION Insertional calcific tendinopathy of the Achilles tendon is common, but few patients are symptomatic. The incidence of ICT increases with age and is significantly higher in patients with diabetes mellitus and hypothyroidism.

Abstract
Despite the increasing popularity of table tennis worldwide, few studies have focused on table tennis injuries.This study aimed to investigate the injury profiles, including the injury rate, types, locations, and risk factors, among nonprofessional collegiate table tennis athletes in Taiwan.We performed an online investigation among collegiate table tennis athletes of the nonprofessional category in the 2019 National Intercollegiate Athletic Games in Taiwan. Participants provided general information, and data on the characteristics of their play style, training, and injuries were collected. We then categorized these participants into injured and noninjured groups. Injuries were classified as mild, moderate, and severe, based on the time loss in playing table tennis. The risk factors for table tennis-related sports injuries were then identified through between-group comparisons.In total, 150 participants responded to the questionnaire. The average participant age was 21.3 years. Gender differences existed in age categories, forehand rubber, backhand style of play, and average days of training per week. Over the 6 months before the study, 76 of 150 participants experienced at least one injury. The handedness for play was associated with the occurrence of injury. Factors associated with injury severity included using rubber other than inverted rubber for the forehand and not qualifying for the national round of the team category of the National Intercollegiate Athletic Games.With a considerably high injury rate among nonprofessional collegiate athletes, further studies are required on table tennis-related injuries. Playing styles such as handedness and type of rubber used might be associated with the injury. The lower limb was the most common site of injury. These results may provide insights into trainers and coaches for further measures on injury prevention.

Abstract
BACKGROUND Calcific tendinitis of the shoulder has a tendon involvement that could evolve to rotator cuff tear and shoulder osteoarthritis. This study aimed to evaluate the prevalence of glenohumeral osteoarthritis and rotator cuff tears in patients affected by calcific tendinitis at a minimum follow-up of 10 years after diagnosis. METHODS Patients diagnosed with calcific tendinitis of the shoulder with a minimum follow-up of 10 years were contacted and invited for a clinical and radiological evaluation. Information on the demographics, affected and dominant side, bilateral shoulder pain, type of treatment, habits, systemic or musculoskeletal diseases, reoperation of the index shoulder, and subjective satisfaction was collected. The clinical evaluation was performed using Constant-Murley score (CMS), American Shoulder and Elbow Surgeons Score (ASES), and numerical rating scale (NRS); isometric strength in forwarding flexion and abduction was also measured. Each patient also underwent an ultrasound examination to evaluate rotator cuff tendon integrity and a shoulder radiograph to evaluate osteoarthritis. RESULTS Seventy-nine patients were available for a phone interview, and 35 agreed to be examined. The mean age was 58.89 (± 7.9) years at follow-up. The prevalence of glenohumeral osteoarthritis was 17.14% in the study population, with significant progression in 14.29% of the cases, without rotator cuff full-thickness tears. x-Ray examination showed residual calcifications in 31 patients, with a mean diameter of 5.54 mm. In 30 cases, there was a reduction of the diameter; in 4 cases, the calcification increased in size; and in 1 case, the size did not change. The mean ASES score was 74.1 (± 22.7) in the group with calcifications larger than 2 mm and 89.4 (± 8.2) in patients with smaller calcifications (p = 0.08) without correlation with the type of treatment performed. CONCLUSIONS Calcific tendinitis is a self-resolving disease without rotator cuff tears at long-term follow-up or degenerative glenohumeral progression. LEVEL OF EVIDENCE 3, cohort study.

Abstract
BACKGROUND Calcific tendinopathy of the rotator cuff is a common cause of painful disability in the shoulder with unclear aetiology. Diabetes mellitus (DM) is associated with calcific tendinopathy; however, large epidemiological data are lacking. Thus, we conducted a nationwide population-based matched cohort study to investigate the risk for calcific tendinopathy of the shoulder in diabetic patients. METHODS The National Health Insurance Research Database of Taiwan was used to include 42 915 patients newly diagnosed with DM between 1 January 2000 and 31 December 2015 and randomly extract the data of 171 660 individuals, as a matched control group. All individuals were followed-up until the development of calcific tendinopathy or the end of 2015. RESULTS Overall, 122 patients from the DM group (0.284%) developed calcific tendinopathy compared with 340 individuals from the non-DM group (0.198%). The Kaplan-Meier analysis indicated that patients with DM had a higher risk of calcific tendinopathy since the eighth year of follow-up (log-rank test, P = .006). Cox proportional hazard regression revealed that the adjusted hazard ratio of calcific tendinopathy in diabetic patients to that in non-diabetic patients was 1.276 (95% confidence interval 1.037-1.571, P = .002). Moreover, the stratified analysis disclosed that DM was a strong independent risk factor for calcific tendinopathy irrespective of the existing comorbidities. CONCLUSIONS This study demonstrated that patients with DM had a 27% increased risk of developing calcific tendinopathy of the shoulder, 8 years after initially being diagnosed with DM.

Abstract
Background/aim Gout may cause various radiographic abnormalities such as cartilage loss, spurs, sclerosis, and periostal new bone formation. The purpose of this study was to investigate the frequency of Achilles and plantar spurs and related factors in gout patients. Matherial and methods We performed a retrospective review of gout patients, treated at Hacettepe University hospitals between 2014 and 2019. We identified patients from the hospital records using the ICD-10 code (M10). Demographic and clinical features, comorbidities, and foot radiographies were collected. The radiographies were evaluated by a rheumatologist (U.K.) who was experienced in musculoskeletal radiography. Factors predicting the spurs were analyzed by logistic regression analysis. Results 181 patients who had lateral foot radiograph were included in this study. Eighty-one (44.7%) patients had score ≥ 2 Achilles spur, 81 (44.7%) patients had score ≥ 2 plantar spur, and 22 (12.1%) patients had no spur. Age, disease duration, duration between the gout diagnosis and appearing spur, the presence of metabolic comorbidities and hypertension were higher in both Achilles and plantar spurs than no spur group. Forty (22.1%) patients had score ≥ 2 both Achilles and plantar spur. In this group, the mean age was older and the proportion of metabolic comorbidities was higher than the groups of Achilles and plantar spur with a score 0 or 1. Predictor of the development of large or moderate-severe calcaneal spur was the existence of metabolic comorbidity [OR (95% CI): 3.49 (1.11–11.0) and p = 0.033]. Conclusion The presence of metabolic comorbidities increases the frequency of calcaneal spurs in gout patients. This condition can be explained by the impaired microvascular structure and increased hypoxia resulting in calcification on the tendon and ligament insertion sites.

Abstract
BACKGROUND Achilles and patellar tendinopathy are common in runners. Despite the relevance of the problem, causative factors remain poorly understood. This cross-sectional study evaluated the association between Achilles and patellar tendinopathy and age, sex, weight, height, number of marathons, and impact profile in runners who participated in the 2017 Marathon of Rome. METHODS At the 2017 Marathon of Rome, 350 athletes (256 men and 94 women; mean age: 44.8 years, range 12-80 years) filled in the VISA-A and VISA-P questionnaires. A fully trained orthopedic surgeon made a diagnosis of Achilles and patellar tendinopathy according to clinical criteria. RESULTS Ninety-five participants were diagnosed with Achilles tendinopathy and 96 with patellar tendinopathy. There was evidence of a statistically significant positive association between age and Achilles and patellar tendinopathy, with no effect of sex, weight, and height on the presence of Achilles tendinopathy. There was no evidence of a statistically significant positive association between the number of marathons and impact profile and VISA-A score. There was a statistically significant association between VISA-P score and impact profile. Finally, there was evidence of a statistically significant positive association between VISA-A score and VISA-P score (P = 0.007). CONCLUSIONS In marathon runners, there was no evidence of a statistically significant association between sex, weight, height, number of marathons, and Achilles and patellar tendinopathy. However, age was associated with Achilles and patellar tendinopathy, and impact profile was associated with patellar tendinopathy.

Interactive associations of sex and hyperlipidemia with calcific tendinitis of the shoulder in Taiwanese adults. Medicine (Baltimore) 2020; 99:e23299. [PMID: 33181720 PMCID: PMC7668432 DOI: 10.1097/md.0000000000023299] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2020] [Revised: 09/10/2020] [Accepted: 10/22/2020] [Indexed: 11/08/2022] Open
Abstract
Calcific tendinitis (CT) of the shoulder is a painful disorder usually identified in individuals aged 40 and 60 years. The estimated global prevalence of CT is 2.7% to 36%. We examined the association of hyperlipidemia and sex with CT of the shoulder using Taiwan Biobank (TWB) and the National Health Insurance Research Database (NHIRD).Data were available for 9903 TWB participants who were recruited between 2008 and 2015. We used multiple logistic regression analysis to estimate the odds ratios (OR) and 95% confidence intervals (CI) for CT of the shoulder.Overall, 1564 women, and 1491 men were identified with hyperlipidemia. Women, compared to men, had higher odds of CT of the shoulder (OR, 1.53; 95% CI, 1.08-2.16). Hyperlipidemia, compared to no hyperlipidemia, was associated with an increased risk of CT (OR, 1.40; 95% CI, 1.02-1.93). The test for interaction was significant for sex and hyperlipidemia (P = .006). After stratification, the odds ratio for CT was 1.95 (95% CI, 1.30-2.92) in women and 0.82 (95% CI, 0.48-1.39) in men, respectively. Compared to men with no hyperlipidemia, the odds ratio was 0.86 (95% CI, 0.53-1.38) for men with hyperlipidemia and 2.00 (95% CI, 1.29-3.10) for women with hyperlipidemia.Importantly, our findings indicated that the risk for CT of the shoulder was higher among Taiwanese women with hyperlipidemia. However, CT risk among their male counterparts with hyperlipidemia was not significant.

Abstract
INTRODUCTION Musculoskeletal disorders (MSDs) currently represent the first occupational health problem. Tendinopathy of the shoulder is the most common occupational diseas. It is responsible for variable aftereffects arriving until the articular steepness. AIM To determine the influence of clinical and radiological investigations in setting the rate of permanent partial disability related to occupational shoulder tendinopathies. METHODS This is a retrospective study of 63 patients followed for tendinopathy of the shoulder. The files were collected from the regional commission of attribution of the rates of permanent partial incapacity of the victims of the occupational accidents and diseases. For each patient we collected the social and occupational data, the result of the clinical examination and the radiological investigations as well as the attributed PPD rate (partial permanent disability). The data analysis allowed to determine the variation of the PPD according to the articular mobility and according to the severity of the hurts revealed by the radiological investigations. RESULTS The average age of our patients was of 45 years with a feminine predominance (sex ratio 6.87). The patients were mainly workers of confections (51%). The imaging objectified a tendinopathy without tear in 23 cases (36,5 We showed that the rate of PPD increased in a proportional way according to the severity of the limitation of the mobility expressed in degrees lost of abduction or of extension as well as according to the gravity of the hurts revealed by the radiological investigations. CONCLUSION we were able to attribute for every type of radiological lesion and according to the limitation of the mobility an interval of rather specific PPD, this allows directing the experts in the compensation of occupational shoulder tendinopathy victims.

Self-reported pain with single leg heel raise or single leg hop offer distinct information as measures of severity in men with midportion and insertional Achilles tendinopathy: An observational cross-sectional study. Phys Ther Sport 2020; 47:23-31. [PMID: 33125967 DOI: 10.1016/j.ptsp.2020.10.009] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2020] [Revised: 10/17/2020] [Accepted: 10/20/2020] [Indexed: 12/14/2022]
Abstract
OBJECTIVES To investigate if self-reported pain with single leg heel raise (SLHR) or single leg hop (SLH) are concurrently valid to assess midportion (MPAT) or insertional Achilles tendinopathy (IAT) symptom severity, compared to the VISA-A. Additionally, if SLHR or SLH pain accounts for VISA-A variability, and if they are associated with psychological factors. PARTICIPANTS 60 men with MPAT, 26 men with IAT. MAIN OUTCOMES Participants rated SLHR and SLH pain on a numerical rating scale (0 = none, 10 = worst). We investigated relationships between loading task pain, VISA-A, VISA-A constructs, and psychological outcomes (Pearson's correlation coefficients). Linear regression determined best model accounting for VISA-A variability. RESULTS In MPAT, load tests shared fair-negative relationship with VISA-A, and VISA-A function. In IAT, SLHR had moderately strong-negative relationship with VISA-A, and pain and function constructs, and SLH shared fair-negative relationship with VISA-A, and pain and function constructs. Relationships were negligible between load tests and VISA-A activity in both conditions, and VISA-A pain in MPAT. In IAT, there was fair-positive relationship between pain catastrophising and load tests. Remaining psychological outcome relationships were negligible. Best model accounting for VISA-A included SLH in MPAT, and SLHR in IAT. CONCLUSIONS Despite VISA-A and selected VISA-A construct associations, self-reported SLHR and SLH pain appears to provide distinct information.

Abstract
OBJECTIVES To investigate the interaction of ankle-foot complex and hip joint factors with Achilles Tendinopathy (AT) occurrence in recreational runners. DESIGN Cross-sectional. SETTING Research Laboratory. PARTICIPANTS 51 runners, 26 healthy and 25 with AT. MAIN OUTCOMES MEASURES Shank-forefoot alignment (SFA), weight bearing lunge test (WBLT), passive hip internal rotation (IR) range of motion (ROM), hip external rotators (ER) and ankle plantar flexors (PF) isometric strength. CART analyses were performed to assess interactions that could distinguish those with AT. RESULTS Passive hip IR ROM, ankle PF torque, SFA, and hip ER isometric torque were associated AT occurrence. The model correctly classified 92% of individuals without AT and 72% of those with AT. The area under the receiver operating characteristic curve was 0.88. Interaction factors revealed in nodes 3 and 10 were statistically significant. In node 3, runners with more than 29.33° of passive hip IR ROM had a 130% increased likelihood (PR = 2.30) of AT. Node 10 showed that individuals with higher PF torque, SFA varus, ER torque, but reduced passive hip IR ROM had an 87% increased likelihood (PR = 1.87) of AT. CONCLUSION Interactions between hip and foot factors could accurately classify recreational runners with and without AT.

Abstract
Objectives. Musculoskeletal disorders (MSD) represent one of the most relevant occupational problems. School teachers and particularly nursery school teachers (NST) are reported to have a high prevalence of MSD. We aimed to estimate frequency of MSD in a sample of NST and to bring out cases of work-related musculoskeletal disorders (WRMSD) among these workers. Design. Cross-sectional prevalence study. Setting and participants. NST applying to the trade union patronage between December 2015 and December 2017 for problems of absence from work for health reasons have been proposed the compilation of the Italian version of the Nordic Questionnaire for musculoskeletal disorders. NST who reported MSD underwent medical examination performed by an occupational physician. In accordance with current legislation, certification of occupational disease was completed when a plausible occupational origin of the pathology could be identified. Main outcome measures. MSD and WRMSD prevalence. Results. Questionnaires were completed by 82 NST: 75 (91.5% of the sample) reported at least one MSD. 71 NST underwent medical examination. In 32 subjects (39% of the sample) a diagnosis of musculoskeletal pathology was formulated. Based on work history, 20 cases of probable occupational pathology were reported. Occupational etiology was ascertained for 12 subjects (14.6%): 11 cases of lumbar discopathy / lumbar disc herniation and 1 case of both lumbar disc herniation and tendinopathy of shoulder rotator cuff. Conclusion. Prevalence of musculoskeletal disorders was high and the most frequently affected body sites were similar to those reported in the literature, confirming NST as a group at risk for developing both MSD and WRMSD. Results indicate the importance of taking primary and secondary prevention actions to protect the health of NST.

Achilles Tendinopathy: Pathophysiology, Epidemiology, Diagnosis, Treatment, Prevention, and Screening. JOURNAL OF SPECIAL OPERATIONS MEDICINE : A PEER REVIEWED JOURNAL FOR SOF MEDICAL PROFESSIONALS 2020; 20:125-140.

Abstract
Achilles tendinopathy (AT) is a clinical term describing a nonrupture injury of the Achilles tendon where the patient presents with pain, swelling, and reduced performance and symptoms exacerbated by physical activity. About 52% of runners experience AT in their lifetime and in the United States military the rate of clinically diagnosed AT cases was 5/1000 person-yr in 2015. The pathophysiology can be viewed on a continuum proceeding from reactive tendinopathy where tenocytes proliferate, protein production increases, and the tendon thickens; to tendon disrepair in which tenocytes and protein production increase further and there is focal collagen fiber disruption; to degenerative tendinopathy involving cell death, large areas of collagen disorganization, and areas filled with vessels and nerves. Inflammation may be present, especially in the early phases. Some evidence suggests AT pain may be due to neovascularization and the ingrowth of new nerve fibers in association with this process. Prospective studies indicate that risk factors include female sex, black race, higher body mass index, prior tendinopathy or fracture, higher alcohol consumption, lower plantar flexion strength, greater weekly volume of running, more years of running, use of spiked or shock absorbing shoes, training in cold weather, use of oral contraceptives and/ or hormone replacement therapy, reduced or excessive ankle dorsiflexion range of motion, and consumption of antibiotics in the fluoroquinolone class. At least 10 simple clinical tests are available for the diagnosis of AT, but based on accuracy and reproducibility, patient self-reports of morning stiffness and/or pain in the tendon area, pain on palpation of the tendon, and detection of Achilles tendon thickening appear to be the most useful. Both ultrasound and magnetic resonance imaging (MRI) are useful in assisting in diagnosis with MRI providing slightly better sensitivity and specificity. Conservative treatments that have been researched include: (1) nonsteroidal anti-inflammatory medication, (2) eccentric exercise, (3) stretching, (4) orthotics, (5) bracing, (6) glyceryl trinitrate patches, (7) injection therapies (corticosteroids, hyaluronic acid, platelet-rich plasma injections), (8) shock wave therapy, and (9) low-level laser therapy. Nonsteroidal anti-inflammatory medication and corticosteroid injections may provide short-term relief but do not appear effective in the longer term. Eccentric exercise and shock wave therapies are treatments with the highest evidence- based effectiveness. Prevention strategies have not been well researched, but in specific populations balance training (soccer players) and shock-absorbing insoles (military recruits) may be effective. Ultrasound scans might be useful in predicting future AT occurrences.

Abstract
The biggest compartment of the musculoskeletal system is the tendons and ligaments. In particular, tendons are dense tissues connecting muscle to bone that are critical for the integrity, function and locomotion of this system. Due to the increasing age of our society and the overall rise in engagement in extreme and overuse sports, there is a growing prevalence of tendinopathies. Despite the recent advances in tendon research and due to difficult early diagnosis, a multitude of risk factors and vague understanding of the underlying biological mechanisms involved in the progression of tendon injuries, the toolbox of treatment strategies remains limited and non-satisfactory. This review is designed to summarize the current knowledge of triggers, trails and end state of tendinopathies.

Abstract
Tendinopathy is a critical medical condition that often hinders level of participation for professional and young athletes in many sports. The purpose of the study was to describe the incidence and severity of tendinopathy in a multi-sport club with professional and youth teams. We performed a retrospective epidemiological study. Incidence of tendinopathy in players (n = 3839; 8-38 years, professional and youth) was reviewed over 8 seasons (2008-2016) in 5 team sports: football, basketball, handball, roller hockey, and futsal. Team physicians diagnosed and classified tendinopathies according to anatomical location, sport types, playing category, sex, playing surface, lost training time, and severity (time to return to play). Injuries were coded using OSICS-10, and incidence of tendinopathies were calculated as the number of injuries per 100 players per season. The total relative frequency of tendinopathy (versus total injuries) was 22% (843/3839) over 8 seasons from 360 in youth and 483 in professional teams. The incidence of injury was the highest in professional basketball [69.9, 95%CI: (58.0-81.4)] followed by professional roller hockey [64.4, 95%CI: (47.3-85.6)], and professional futsal [36.2, 95%CI: (27.3-47.1)]. The most incidences commonly affected tendons were the patellar [11.7, 95%CI: (10.0-13.5)] and Achilles [10.3, 95%CI: (8.5-12.5)]. Tendinopathies represent a significant number of injuries in team sports and are more common in professional than youth teams, especially basketball and roller hockey. Additional studies are needed to understand associated time-loss and impact on performance, and to develop prevention strategies for high risk sports.

Abstract
Previous etiologic studies have indicated that both environmental and genetic factors play important roles in the occurrence and development of chronic Achilles tendinopathy (AT). A recent study documented the results of the largest genome-wide association study for chronic AT to date, indicating that MPP7, TIMP2 and CASP8 may be involved in the occurrence and development of chronic AT. In this study, we aimed to investigate whether MPP7, TIMP2 and CASP8 were associated with susceptibility to chronic AP in a Han Chinese population. A total of 3,680 study subjects comprised 1,288 chronic AT cases, and 2,392 healthy controls were recruited. Forty-four tag SNPs (7 from CASP8, 20 from MPP7, and 17 from TIMP2) were genotyped in the study. Genetic association analyses were performed at both single marker and haplotype levels. Functional consequences of significant SNPs were examined in the RegulomeDB and GTEx databases. Two SNPs, SNP rs1937810 (OR [95%CI] = 1.20 [1.09-1.32], χ2 = 13.50, P = 0.0002) in MPP7 and rs4789932 (OR [95%CI] = 1.24 [1.12-1.37], χ2 = 17.98, P = 2.23 × 10-5) in TIMP2, were significantly associated with chronic AT. Significant eQTL signals for SNP rs4789932 on TIMP2 were identified in human heart and artery tissues. Our results provide further supportive evidence for the association of the TIMP2 and MPP7 genes with chronic AT, which supports important roles for TIMP2 and MPP7 in the etiology of chronic AT, adding to the current understanding of the susceptibility of chronic AT.

Abstract
Data on elite gymnast injuries outside North America is sparse. We report the injuries recorded over a period of 10 years in 156 Greek elite male and female gymnasts. A total of 2390 injuries were reported for a rate of 1,5 new injuries per year per athlete. Most commonly affected areas were the hip (18.5%), the ankle (16.5%), the lumbar spine (16%) and the foot (16%). The most frequent diagnosis was tendinitis (32%), followed by low back pain (20%), and sprains (12%). Fifteen athletes (9%) sustained serious injuries that required surgery. Rhythmic gymnasts had significantly more overuse type injuries compared to artistic gymnasts (p = 0.049). Gymnastics is a sport with a high incidence of musculoskeletal pathology that needs proper documentation in order to establish preventive measures.

Abstract
BACKGROUND AND AIMS Achilles tendon lesions have long been associated with genetic defects in lipid metabolism and increased risk of cardiovascular diseases (CVD). With this study we aimed to evaluate the usefulness of Achilles tendon ultrasonography in identifying people at greater risk among subjects with severe hypercholesterolemia (SH) in a high-risk population. METHODS During the period of 2016-2017 a total of 213 participants were enrolled in this case-control study. Data of 110 patients with SH and 103 age and sex matched controls without dyslipidaeplemia and established CVD was collected. RESULTS Achilles tendinopathy (AT) was present in 42.7% of subjects with SH and in 29.1% of controls (p = 0.039). Stronger association between SH and AT was seen in women - 24.1% vs 2.0% (p = 0.001). SH increased odds of AT by 1.815 (95% CI, 1.028-3.206). Prevalence of AT was higher in males despite presence (SH+) or absence (SH-) of severe hypercholesterolemia (SH+ 60.7% vs 24.1%, SH- 55.8% vs 2.0%, p < 0.001). AT was associated with higher proportion of subjects exceeding normal mean values of TC (80.5% vs 52.9%, p = 0.001), LDL-C (76.6% vs 52.2%), TG (54.5% vs. 22.1%), ApoB (57.1% vs 22.2%), ApoE (44.0% vs 22.4%) levels and ApoB/ApoA ratio (46.1% vs 21.5%) (p = 0.001) and family history of premature coronary heart disease (CHD). CONCLUSIONS AT is more prevalent among subjects with SH and is associated with higher levels of TC, TG, LDL-C, ApoB, ApoE, ApoB/ApoA ratio, family history of premature CHD. SH increases the odds of developing AT.

Abstract
De Quervain's disease, carpal tunnel syndrome (CTS), and trigger finger (digit) are three common pathological conditions of the hand. They are considered overuse syndromes and occur predominantly in females. The prevalence rate and cause-specific risks of these three tendinopathies have not yet been clarified. Data from 41,871 cases listed in the Taiwan National Health Insurance Research Database (NHIRD) from 2010 to 2014 were analyzed. The prevalence rate of these 3 conditions by age, sex, and the risk factors of female-dominant diseases (e.g., osteoporosis, rheumatoid arthritis [RA], and tendinopathy), diabetes mellitus, and hormone antagonist treatment was evaluated. We found that 1.59% of the population developed CTS, 0.49% developed de Quervain's, and 1.07% developed trigger finger. Cases were more likely to develop the three hand tendinopathies if they were female, between 50 and 59 years old, and, according to a multivariate analysis, comorbid with RA, diabetes, using hormone antagonists. Our findings should provide an understanding of the risk factors associated with hand tendinopathy.

Abstract
BACKGROUND The absence of a single, identifiable traumatic cause has been traditionally used as a definition for a causative factor of overuse injury. Excessive loading, insufficient recovery, and underpreparedness can increase injury risk by exposing athletes to relatively large changes in load. The musculoskeletal system, if subjected to excessive stress, can suffer from various types of overuse injuries which may affect the bone, muscles, tendons, and ligaments. METHODS We performed a search (up to March 2018) in the PubMed and Scopus electronic databases to identify the available scientific articles about the pathophysiology and the incidence of overuse sport injuries. For the purposes of our review, we used several combinations of the following keywords: overuse, injury, tendon, tendinopathy, stress fracture, stress reaction, and juvenile osteochondritis dissecans. RESULTS Overuse tendinopathy induces in the tendon pain and swelling with associated decreased tolerance to exercise and various types of tendon degeneration. Poor training technique and a variety of risk factors may predispose athletes to stress reactions that may be interpreted as possible precursors of stress fractures. A frequent cause of pain in adolescents is juvenile osteochondritis dissecans (JOCD), which is characterized by delamination and localized necrosis of the subchondral bone, with or without the involvement of articular cartilage. The purpose of this compressive review is to give an overview of overuse injuries in sport by describing the theoretical foundations of these conditions that may predispose to the development of tendinopathy, stress fractures, stress reactions, and juvenile osteochondritis dissecans and the implication that these pathologies may have in their management. CONCLUSIONS Further research is required to improve our knowledge on tendon and bone healing, enabling specific treatment strategies to be developed for the management of overuse injuries.

Abstract
OBJECTIVE To perform a systematic review and meta-analysis identifying (1) potential modifiable risk factors and (2) associated modifiable factors for patellar tendinopathy in athletes. DESIGN A systematic review and meta-analysis was conducted. Risk of bias was assessed using the Newcastle-Ottawa Scale and grouped based on study design. Meta-analytic statistics were performed for items reported by five or more studies. A strength of evidence rating is provided for items not appropriate for meta-analysis. DATA SOURCES PubMed, Web of Science, Scopus and Cinahl were searched on 14 November 2017. ELIGIBILITY CRITERIA Quantitative, original research reporting potential modifiable risk factors or associated factors, comparing athletes with patellar tendinopathy with a group without the injury. RESULTS 862 records were screened and 31 articles were included (6 prospective, 25 cross-sectional). There was a lack of strong evidence for any potential modifiable risk factor or associated factors. There was limited or conflicting evidence that decreased ankle dorsiflexion range of motion, decreased posterior thigh and quadriceps flexibility, greater volume of jump training, more volleyball sets played per week, greater countermovement jump (CMJ) height and greater activity volume are potential modifiable risk factors. Meta-analysis supported greater activity volume (Cohen's d=0.22, 95% CI 0.06 to 0.39, p=0.008), higher body weight (0.36, 0.17 to 0.55, p<0.001) and greater CMJ height (0.31, 0.07 to 0.56, p=0.01) as associated modifiable factors. CONCLUSIONS There is a lack of strong evidence for any potential modifiable risk factors or associated factors. Factors with lower levels of support may be of interest in designing prevention programmes but require further research in high-quality, prospective studies.

Tendon thickening in dialysis-related joint arthritis is due to amyloid deposits at the surface of the tendon. Joint Bone Spine 2018; 86:233-238. [PMID: 30243785 DOI: 10.1016/j.jbspin.2018.08.005] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2018] [Accepted: 08/24/2018] [Indexed: 11/17/2022]
Abstract
OBJECTIVES Beta-2-microglobulin (β2M) dialysis-related amyloidosis (DRA), a disabiliting joint disease, has been initially reported in patients under long-term dialysis. The incidence and prevalence has significantly decreased with the improvement in dialysis techniques. Here, we attempted to clarify the clinical and MRI features to improve the diagnosis. METHODS We retrospectively reviewed the files of 19 patients under dialysis treatment referred for suspicion of β2M DRA. The diagnosis was based on MRI criteria (low signal intensity on both T1- and T2-weighted MR sequences). MRI analysis included a scoring of the several joint lesions. Scores were quantified according to a severity scale (0 to 3). RESULTS Patients had a mean age of 66.0 ± 10.5 years and mean dialysis duration of 23.7 ± 10.5 years. DRA affected mainly large joints (shoulder in 73.7%, hip in 47.3%) and spine (36.8%). MRI images for 8 shoulders, 8 hips, and 3 spines were analysed. Amyloid synovitis was present in all cases, with high mean scores in the three sites. In all joints, the most common lesions were tendon thickening (68.4%) and bone erosions (68.4%). The mean tendon thickening score was high, particularly at the shoulders and also at the spine. Bone erosions were most frequent in the shoulder and pelvis. CONCLUSION In patients under long-term dialysis, β2M DRA involves large joints but also the spine. Special awareness should be drawn by the thickening of the tendon. MRI is required to characterize the pattern of the lesions and to achieve the diagnosis.

Abstract
This study aims to analyze the incidence, location, type, and mechanisms of injuries and possible injury risk factors among all levels of Korean female professional golfers. This was a prospective study with a follow-up period of 24 months. A total of 363 members of the Korean Ladies Professional Golf Association (KLPGA), who competed in tournaments during the 2015 and 2016 seasons, took part in the study. The incidence of injury varied by tournament level and was significantly higher in Division II (11.1/1000AEs) and Division III (13.4/1000AEs) than in Division I (5.6/1000AEs) (p < 0.05). The most common location and type of injury were the shoulder/clavicle (Division I: 14.1%, Division II: 15.7%, Division III: 17.3%) and the tendinosis or tendinopathy (21.2%) (Division I: 23.7%, Division II: 21.2%, Division III: 18.5%), respectively. The most common mechanism of injury was the golf swing (47.9%-51.6% for the three divisions), and the most frequent specific phase of injury was upon ball impact (23.5%-30.9%). Multivariate analysis revealed that body mass index and the number of previous season competitions were significantly associated with injury risk in female golfers. The other factors examined did not have a significant association with golf-related injuries. In conclusion, KLPGA golfers were commonly exposed to injuries and showed a higher rate of injuries in competitions than practices, with significantly higher in Division II, III than Division I. However, overall, there was no significant difference in the location, type, mechanism and risk factors for injuries among the division level of KLPGA.

Abstract
Proximal hamstring tendinosis and partial hamstring origin ruptures are painful conditions of the proximal thigh and hip that may occur in the acute, chronic, or acute on chronic setting. Few publications exist related to their diagnosis and management. This systematic review discusses the incidence, treatment, and prognosis of proximal hamstring tendinosis and partial hamstring ruptures. Conservative treatment measures include nonsteroidal anti-inflammatory drugs, physical therapy, rest, and ice. If these measures fail, platelet-rich plasma or shockwave therapy may be considered. When refractory to conservative management, these injuries may be treated with surgical debridement and hamstring reattachment. [Orthopedics. 2017; 40(4):e574-e582.].

Abstract
INTRODUCTION Diabetes mellitus is one of the most common metabolic problems and is characterized by persistent hyperglycaemia. Exposure to chronic hyperglycaemia can affect many tissues including the Achilles Tendon, which is one of the largest tendons in the body. The current literature on the effects of hyperglycaemia on tendons is sparse, though evidence on rat models does suggest a process of chronic degeneration, which is increased in the presence of neuropathy and deformity. There is no epidemiological data on rupture of Achilles tendon in diabetes. Similarly, the knowledge of the best treatments for this condition in people with diabetes is also lacking. CONCLUSION In this review we have systematically analysed current literature in this area and suggested future studies.

Abstract
BACKGROUND Tendon pathology and tendinopathy have been reported in children and adolescents; however, the age at onset and prevalence of the conditions have not been examined systematically. OBJECTIVE To examine the prevalence of lower limb tendon pathology and tendinopathy in children and adolescents, and the factors associated with these conditions in this population. METHODS Six databases were searched (MEDLINE, the Cochrane Central Register of Controlled Trials, Embase, Scopus, the Web of Science and the Allied and Complementary Medicine Database). Studies were included if the prevalence of lower limb tendon pathology and/or tendinopathy were reported in humans under the age of 18 years. Studies were divided according to the method of diagnosis (physical examination, ultrasound or a questionnaire) and further divided into studies that reported prevalence data by tendon [reported two data points (right and left) for each participant] and those that reported prevalence data for each participant [reporting one data point (right or left) per participant]. RESULTS Seventeen studies met the inclusion criteria. Lower limb tendinopathy prevalence (presence of pain and dysfunction) ranged between 8.2 and 33.3%, and increased in prevalence as age increased up to 18 years. The odds ratio for studies reporting tendinopathy by tendon was 0.37 (95% confidence interval 0.20-0.69) in favour of boys presenting with tendinopathy. Study aims and reporting methods were heterogeneous. CONCLUSIONS The age at onset of lower limb tendinopathy in children and adolescents has not been widely studied. This systematic review found that tendinopathy is present in children and adolescents, and increases in prevalence with age up to 18 years. Male sex is significantly associated with tendinopathy in studies that report tendinopathy by tendon.

Abstract
BACKGROUND Exercise is an important therapeutic tool in the management of diabetes in older people. Aim of this study was to assess the relationship among type II diabetes, sport, overweight, and symptomatic Achilles tendinopathy in elderly subjects. METHODS Thirty-eight patients suffering from Achilles tendinopathy and thirty-eight controls were enrolled. The prevalence of diabetes and sport practice as well as BMI and Glycated Hemoglobin (HbA1c) values were registered. An ultrasound evaluation of Achilles tendon was performed. RESULTS Patients showed an increased prevalence of diabetes (42 vs. 13.1 %, p = 0.004), and practice of sport (60.5 vs. 28.9 %, p = 0.0001), and higher BMI values (26.8 ± 3 vs. 24.8 ± 2.3, p = 0.001). Sonographic abnormalities, being diagnostic criteria, were present in all the patients with Achilles tendinopathy, but signs of degeneration were also found in 36.8 % of asymptomatic controls. Symptomatic subjects with diabetes, compared to those without, showed a higher prevalence of severe degeneration (75 vs. 36.3 %, p = 0.01). HbA1c values were significantly lower in sport practitioners, both diabetics and non-diabetics. Moreover, patients practicing sport showed a trend towards lower BMI values, compared to the sedentary counterpart. CONCLUSIONS Sport practice in elderly diabetics provides relevant metabolic advantages, reducing HbA1c and BMI. However, some sport activities (e.g., speed walking, jogging or tennis) can expose to the risk of Achilles tendinopathy. So, sport practice should be encouraged, but practitioners should follow individual training programs and be submitted to periodic sonographic controls.

Abstract
BACKGROUND In the last few years, the incidence of upper limbs tendon injuries has seen a dramatic increase among workers. Conservative treatment is the first choice to relieve symptoms, allowing a safe return to work. However, the scientific evidence of its efficacy is widely debated. OBJECTIVE AND METHODS Research and literature review on the efficacy of conservative treatment of upper limbs tendon injuries in occupational settings. RESULTS A total of 271 references were found on Medline and Embase up to May 2015. 116 papers were excluded, 155 articles were included and the full text read. CONCLUSIONS After a timely diagnosis, a prompt start of the rehabilitation programme and a limitation of complete rest are useful to relieve pain, increase functionality and reduce work absenteeism in the long term. Conservative treatment combinations, such as manual therapy, specific exercises focused on increasing flexibility and muscle strength and specific-gesture training, achieves more significant results than a single isolated treatments. Currently, there is no strong scientific evidence to support prolotherapy and Platelet-Rich Plasma (PRP). However, current promising results will encourage further studies. Awareness among both employers and employees about prevention and risk factors should be enhanced.

Abstract
AIM Beach volleyball is an overhead sport that subjects the hitting shoulder to intense functional loads. The purpose of this study is to identify ultrasonographically the prevalence of myotendinous alterations in professional Italian beach volleyball players at the Italian championship and to look for associations between ultrasound findings and the other data collected. METHODS Fifty-three beach volleyball players (31 women, 22 men) were recruited during the second stage of the Italian championship held in July 2012 in Rome, Italy. Clinical history was obtained from all subjects, followed by physical exam. Each athlete completed a questionnaire regarding sports activities. Bilateral ultrasonographic evaluation of the shoulders was then performed. RESULTS Calcific tendinopathy of the rotator cuff of the hitting shoulder was identified ultrasonographically in 30% of the athletes. The mean age of the athletes with calcific tendinopathy was older than subjects with other abnormalities on ultrasonographic examination (33.1 years vs. 25.8 years, t-test; P<0.0001). Impingement was recognized ultrasonographically in the hitting shoulder in 10 of the athletes (18.8%). The Neer's test was positive in the cases of anterior impingement (χ2; P<0.002). CONCLUSION Calcific tendinopathy of the rotator cuff of the hitting shoulder in professional beach volleyball players has a prevalence of 30% ultrasonographically, greater than that reported in the general population. In these athletes, the presence of calcific tendinopathy correlates positively with age.

Abstract
Plantar spurs and Achilles tendinopathy are common causes of heel pain. In the authors' practice, it was anecdotally noted that patients with Achilles tendinopathy often presented with plantar spurs. Nonetheless, there is a shortage of studies investigating whether Achilles tendinopathy and plantar spurs exist concomitantly. A better understanding of the association between the 2 pathologies might help physicians recognize and treat both conditions, educate patients about Achilles tendinopathy and plantar spurs, and ultimately investigate possible underlying causes of both pathologies that could be addressed together. The authors examined the prevalence of plantar spurs in patients diagnosed with Achilles tendinopathy as well as demographic differences within the unilateral and bilateral Achilles tendinopathy populations. A total of 785 patient records were retrospectively reviewed. Mean patient age was 56.2±15.5 years (46.9% men and 53.1% women). Seventy-two (9.2%) patients were affected bilaterally by Achilles tendinopathy. Lateral radiographs were reviewed by an orthopedic surgeon to identify the presence of plantar spurs. A total of 329 (41.9%) patients with Achilles tendinopathy were found to have a concomitant plantar spur. Patients with unilateral Achilles tendinopathy and a plantar spur were more likely to be women (58.7% vs 49.8%, P=.020) and older (62.7 vs 51.7 years, P<.001). In the bilateral Achilles tendinopathy group, there were 46 (63.9%) patients with at least one foot presenting with a plantar spur. The study's findings suggest a significant association between Achilles tendinopathy and plantar spurs. Older women with Achilles tendinopathy are at greater risk of being affected by plantar spurs.

Abstract
PURPOSE To evaluate the efficacy of pronator quadratus (PQ) repair after volar plating of distal radius fractures. METHODS All consecutive distal radius fractures treated operatively with a volar plate during a 1-year period were assigned to receive a repair of the PQ versus no repair. Surgical exposure, reduction, and postoperative rehabilitation were equivalent in both groups. Clinical outcomes with a minimum follow-up of 12 months were assessed via range of motion; grip strength; Disabilities of the Arm, Shoulder, and Hand (DASH) scores; and visual analog scale (VAS) scores. RESULTS A total of 60 consecutive distal radius fractures were treated operatively with a locking volar plate. Full follow-up data were available for 33 patients in the PQ repair group and 24 patients in the control group. At 12 months, the mean DASH score was 8 for the repair group and 5 for the control group. Range of motion at the wrist, grip strength, and VAS scores were also not significantly different between groups. In addition, we found no significant differences in any of the parameters at the 2-, 6-, or 12-week intervals, although we observed greater grip strength and wrist flexion in the repair group at 6 weeks. Reoperation was required for 4 patients in the repair group and 1 in the control group. CONCLUSIONS Pronator quadratus repair after volar plating of a distal radius fractures did not significantly improve postoperative range of motion, grip strength, or DASH and VAS scores at 1 year. The rates of reoperation between groups were not significantly different.

Abstract
PURPOSE To determine function and complications after reverse total shoulder arthroplasty (RTSA) in obese patients compared with a control group of nonobese patients. METHODS Between 2005 and 2011, we performed 76 RTSAs in 17 obese, 36 overweight, and 23 normal weight patients, based on World Health Organization body mass index classification. We reviewed the charts for age, sex, body mass index, date of surgery, type of implant, type of incision, length of stay, comorbidities, surgical time, blood loss, American Society of Anesthesiologists score, shoulder motion, scapular notching, and postoperative complications. Complications and outcomes were analyzed and compared between groups. RESULTS Reverse total shoulder arthroplasty in obese patients was associated with significant improvement in range of motion. Complication rate was significantly greater in the obese group (35%), compared with 4% in the normal weight group. We found no significant differences between scapular notching, surgical time, length of hospitalization, humeral component loosening, postoperative abduction, forward flexion, internal and external rotation, pain relief, or instability between groups. CONCLUSIONS Our results show that obese patients have significant improvement in motion after RTSA but are at an increased risk for complication. Obesity is not a contraindication to RTSA, but obese patients need to understand fully the increased risk of complication with RTSA. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic III.

Abstract
Background Musculoskeletal injuries occur frequently in runners and despite many studies about running injuries conducted over the past decades it is not clear in the literature what are the main running-related musculoskeletal injuries (RRMIs). Objective The aim of this study is to systematically review studies on the incidence and prevalence of the main specific RRMIs. Methods An electronic database search was conducted using EMBASE (1947 to October 2011), MEDLINE (1966 to October 2011), SPORTDiscus™ (1975 to October 2011), the Latin American and Caribbean Center on Health Sciences Information (LILACS) [1982 to October 2011] and the Scientific Electronic Library Online (SciELO) [1998 to October 2011] with no limits of date or language of publication. Articles that described the incidence or prevalence rates of RRMIs were considered eligible. Studies that reported only the type of injury, anatomical region or incomplete data that precluded interpretation of the incidence or prevalence rates of RRMIs were excluded. We extracted data regarding bibliometric characteristics, study design, description of the population of runners, RRMI definition, how the data of RRMIs were collected and the name of each RRMI with their rates of incidence or prevalence. Separate analysis for ultra-marathoners was performed. Among 2924 potentially eligible titles, eight studies (pooled n = 3500 runners) were considered eligible for the review. In general, the articles had moderate risk of bias and only one fulfilled less than half of the quality criteria established. Results A total of 28 RRMIs were found and the main general RRMIs were medial tibial stress syndrome (incidence ranging from 13.6% to 20.0%; prevalence of 9.5%), Achilles tendinopathy (incidence ranging from 9.1% to 10.9%; prevalence ranging from 6.2% to 9.5%) and plantar fasciitis (incidence ranging from 4.5% to 10.0%; prevalence ranging from 5.2% to 17.5%). The main ultra-marathon RRMIs were Achilles tendinopathy (prevalence ranging from 2.0% to 18.5%) and patellofemoral syndrome (prevalence ranging from 7.4% to 15.6%). Conclusion This systematic review provides evidence that medial tibia stress syndrome, Achilles tendinopathy and plantar fasciitis were the main general RRMIs, while Achilles tendinopathy and patellofemoral syndrome were the most common RRMIs for runners who participated in ultra-marathon races.

Abstract
PURPOSE OF THE STUDY Tuberculosis (TB) in a joint region presents high risk of damage to the joint. Consequences of a late diagnosis and inadequate therapy may be serious particularly in the large joints of lower extremities. Tuberculosis of knee and hip joints accounts for about 25% to 35% of osteoarticular tuberculosis (OAT). The aim of this study was to evaluate the objective and subjective results of tuberculosis treatment in knee and hip joints. MATERIAL AND METHODS Of 258 OAT patients treated at the Specialised Treatment Centre Jevíčko between January 2005 and September 2012, tuberculosis of the hip joint was diagnosed in 31 patients in whom three hips were treated by incision and drainage and 10 by total hip replacement; 18 patients had tuberculosis of the knee joint with the following treatment: puncture in seven knees, incision and drainage in eight, excochleation of a tuberculous focus in the proximal tibia in two, removal of a bursa in one, arthrodesis in four and total knee replacement in four patients. The patients continued to be followed up at the Jevíčko Centre. The scale of 1 to 5 (best to worst) was established for evaluation of objective and subjective results of the treatment. The data were analysed using the basic statistical characteristics and compared. RESULTS The objective evaluation was better for the hip joint; the sums of relative frequencies of marks 1 to 3 were 72.22% in the knee and 80.65% in the hip. In the knee more than 50% of the cases fell in the interval <1.304; 4.252>, in the hip this was <1.296; 3.672>. The hip joint was better subjectively evaluated, it had a higher sum of relative frequencies of marks 1 to 3, i.e., 96.77% as compared with 88.89% for the knee. In the knee more than 50% of the cases had marks in the interval <0.767; 3.122>; in the hip this was <0.869; 2.680>. The hip joint was better evaluated both objectively and subjectively. DISCUSSION An early diagnosis allows for the treatment of synovitis, which has a better prognosis than an arthritic disease. The subjective perception of treatment results showed a better evaluation than its objective correlate. Many patients were satisfied with the results, even with an immobilised joint (in arthrodesis). Total joint replacement in OAT patients does not always provide expected results in either knee or hip joints. Arthrodesis also has its indications related to health condition, age and social status of the patient. In periprosthetic TB infections, a careful consideration should be given to removal of the prosthesis and its re-implantation in relation to all circumstances associated with each particular case. CONCLUSIONS Tuberculosis of large weight-bearing joints is a rare entity in the countries with low TB prevalence, including the Czech Republic. It is necessary to pay attention to diagnosis and therapy and make them more effective even at higher costs associated with total hip replacement in TB or post-TB patients in order to maintain or restore joint function. At the time of borders open for citizens from countries with higher TB prevalence, the diagnosis of OAT should be considered.

Abstract
Tendinopathy is a general term that describes any painful condition that occurs in or around a tendon. Historically, treatments have been directed at inflammation, but an improved understanding of the pathophysiology of tendinopathy has led to redirecting the treatment toward methods that address the underlying pathophysiology. Anti-inflammatory treatments such as NSAIDs and corticosteroid injections are still in common use. Novel treatments such as topical nitrates and platelet rich plasma injections aim to address the biological changes seen in tendinopathy, but evidence of clinical benefit is scant. This article reviews the most widely used treatments for tendinopathy and outlines the literature support for their use.

Abstract
Rotator cuff disease is among the most common musculoskeletal disorders with high direct and indirect costs in industrialized countries. Not all rotator cuff tears are symptomatic. Genetics has recently been investigated as a factor involved in the pathogenesis of rotator cuff pathology. Genetic factors seem to be involved in symptom presentation and tear progression. As rotator cuff disease is multifactorial, no single gene is directly involved in the pathology. Phenotypic expression of genetic susceptibility manifests at the level of ultrastructure of the tendon. Predisposing genes may also operate through apoptosis and regenerative capacity. Studies on cellular and molecular biology are more numerous, but still incomplete, and recently have focussed on the role of apoptosis in tendinopathy, analyzing its key mediators and cellular changes. Oxidative stress is responsible for reduction of collagen synthesis. Biological investigations have identified recently new risk factors. Preliminary reports introduced the possible role of glucose as a risk factor for rotator cuff tear. Further studies are required to fully clarify the genetic and biological factors involved in rotator cuff tears.

Abstract
The use of the word degeneration, particularly in the compensation arena, is not recommended. It is imprecise and is interpreted in different ways by radiologists, clinicians and insurers. Insurers use the word to conclude that any so called degenerative changes mean that there is age causation so that compensation can be denied. These changes can be caused by single or multiple injuries continuing heavy work and other causes. Each risk factor should be carefully assessed in each case.

Abstract
Dentists are exposed to several occupational risks. This study aimed at comparing the prevalence of referred morbidity among Brazilian dentists with that reported by doctors, lawyers, and the general population. Data on referred morbidity were obtained from the Brazilian Household Survey. Stratification by gender was performed, and prevalence rate ratios were calculated. Dentists were more likely to report back pain and arthritis than physicians or lawyers. Dentists also reported tendinitis more frequently than physicians, lawyers, and the general population. Stratification revealed that, when compared to physicians and lawyers, male dentists were more likely to refer to back pain and arthritis than did female dentists. However, female dentists were at higher risk to report tendinitis when compared to all 3 reference populations. This study suggests that Brazilian dentists are at higher risk to develop musculoskeletal disorders.

[PMID: 20691562 PMCID: PMC3074176 DOI: 10.1016/j.arthro.2010.02.029] [Citation(s) in RCA: 46] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2009] [Revised: 02/15/2010] [Accepted: 02/19/2010] [Indexed: 02/02/2023]
Abstract
PURPOSE The purposes of this study was to better understand the utilization of anterior acromioplasty over time, in the absence of rotator cuff repair; to examine the relation to patient characteristics (age, sex) and types of rotator cuff pathology (inflammation or fibrosis, partial-thickness tearing, full-thickness tearing undergoing debridement); and to assess the utilization of arthroscopy in this procedure. METHODS Using the resources of the Rochester Epidemiology Project, cataloging medical records of residents in Olmsted County, Minnesota, we identified 246 patients who underwent anterior acromioplasty between 1980 and 2005. It has previously been shown that rarely does a resident of Olmsted County undergo an orthopaedic procedure at a facility outside the county. RESULTS The incidence of anterior acromioplasty increased over time (P < .001), with crude rates of 3.3 per 100,000 persons in 1980 to 1985 and 19.0 per 100,000 persons in 2000 to 2005. Sex, age, and types of rotator cuff pathology did not significantly change over the 26-year period. There was a dramatic shift from use of the open approach to the arthroscopic approach over this time period (P < .001) and a decrease in the concomitant performance of distal clavicle resection (P < .001). CONCLUSIONS The frequency of anterior acromioplasty has dramatically increased over time. Increasing knowledge about this syndrome, including better imaging, has facilitated patient treatment for a stable spectrum of rotator cuff pathology (inflammation or fibrosis, partial-thickness tearing, full-thickness tearing undergoing debridement), as has the application of endoscopic surgery. LEVEL OF EVIDENCE Level III, epidemiologic study.

Injury patterns in female Irish dancers. PM R 2010; 2:1030-4. [PMID: 20800567 DOI: 10.1016/j.pmrj.2010.05.013] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2010] [Revised: 05/14/2010] [Accepted: 05/18/2010] [Indexed: 11/19/2022]
Abstract
OBJECTIVE To determine the type of Irish dance injuries requiring evaluation and treatment by a sports medicine physician. DESIGN Cross-sectional retrospective chart review. SETTING Academic sports medicine center in the Midwest. PARTICIPANTS Female Irish dancers who presented at an academic sports medicine center from June 2002 to September 2009. MAIN OUTCOME MEASURES This was a retrospective chart review identifying injuries sustained to female Irish dancers in a single Irish dance company in a major metropolitan area. Dancers were evaluated and injuries were diagnosed by one sports medicine physician at an academic sports medicine center. RESULTS Sixty-nine female Irish dancers, ages 8 to 23 years, sustained 217 recorded injuries. The top injuries included stress fractures (29.9%), patellofemoral pain syndrome (11.1%), Sever condition (6.0%), ankle sprains (5.1%), posterior tibialis tendonitis (4.6%), and plantar fasciitis (4.6%). The most common site for stress fractures were the sesamoids, comprising 27.7% of all stress fractures and 8.3% of total injuries. The majority of injuries were in the lower extremities (94.9%), remaining injuries involved the lumbosacral spine and pelvis (5.1%). Most dancers (79.7%) had multiple injuries. The number of injuries per dancer increased as the dancer's level increased. There was a trend for the average age of the dancers to decrease as the level of skill increased. CONCLUSION Lower extremity injuries comprised the majority of Irish dance injuries. Stress fractures (29.9%), patellofemoral pain syndrome (11.1%), and Sever condition (6.0%) were the most common injuries.

Abstract
BACKGROUND Soft tissue rheumatism is a group of common rheumatic disorders reported in many countries. For investigating the prevalence rate of soft tissue rheumatism in different population in China, we carried out a population study in Shantou rural and Taiyuan urban area. METHODS Samples of 3915 adults in an urban area of Taiyuan, Shanxi Province, and 2350 in a rural area of Shantou, Guangdong Province were surveyed. Modified International League of Association for Rheumatology (ILAR)-Asia Pacific League of Association for Rheumatology (APLAR) Community Oriented Program for Control of Rheumatic Diseases (COPCORD) core questionnaire was implemented as screening tool. The positive responders were then all examined by rheumatologists. RESULTS Prevalence rate of soft tissue rheumatism was 2.0% in Taiyuan, and 5.3% in Shantou. Rotator cuff (shoulder) tendinitis, adhesive capsulitis (frozen shoulder), lateral epicondylitis (tennis elbow), and digital flexor tenosynovitis (trigger finger) were the commonly seen soft tissue rheumatism in both areas. Tatarsalgia, plantar fasciitis, and De Quervain's tenosynovitis were more commonly seen in Shantou than that in Taiyuan. Only 1 case of fibromyalgia was found in Taiyuan and 2 cases in Shantou. The prevalence of soft tissue rheumatism varied with age, sex and occupation. CONCLUSIONS Soft tissue rheumatism is common in Taiyuan and Shantou, China. The prevalence of soft tissue rheumatism was quite different with different geographic, environmental, and socioeconomic conditions; and varying with age, sex, and occupation. The prevalence of fibromyalgia is low in the present survey.

Anserine syndrome. REVISTA BRASILEIRA DE REUMATOLOGIA 2010; 50:313-327.

Abstract
Knee pain is a common complaint in clinical practice, and pes anserinus tendino-bursitis syndrome (PATB) has been frequently diagnosed based only on clinical features that may cause equivocal interpretations. Patients complain of characteristic spontaneous medial knee pain with tenderness in the inferomedial aspect of the joint. Studies with different imaging modalities have been undertaken during the last years to identify whether these patients suffer from bursitis, tendinitis, or both. Nevertheless, little is known regarding the structural defect responsible for this disturbance. Due to these problems and some controversies, we suggest the term "anserine syndrome" for this condition. Diabetes Mellitus is a known predisposing factor for this syndrome. Overweight and osteoarthritis seem to represent additional risk factors; however, their role in the pathophysiology of the disease is not yet understood. Treatment includes non-steroidal anti-inflammatory drugs, physiotherapy, and injections of corticosteroid, with highly variable responses, from 10 days to 36 months to achieve recovery. The lack of knowledge about its epidemiological, etiological, and pathophysiological aspects requires future studies for this common and intriguing disorder.

Abstract
BACKGROUND Self-reported tendinitis/tenosynovitis was evaluated by gender, age group, skin color, family income, and educational and psychological status. METHODS !The study was carried out in a representative sample of formally contracted Brazilian workers from a household survey. A total of 54,660 participants were included. Occupations were stratified according to estimated prevalences of self-reported injuries. Non-conditional logistic regression was performed, and all variables were analyzed in two occupational groups. RESULTS The overall prevalence rate of tendinitis/tenosynovitis was 3.1%: 5.5% in high-prevalence occupations (n = 10,726); and 2.5% in low-prevalence occupations (n = 43,934). White female workers between the ages of 45 and 64 years and at a higher socioeconomic level were more likely to report tendinitis/tenosynovitis regardless of their occupational category. An adjusted OR = 3.59 [95% CI: 3.15--4.09] was found between tendinitis/tenosynovitis and psychological status. CONCLUSION Among formally contracted Brazilian workers, higher income can imply greater physical and psychological demands that, regardless of occupational stratum, increase the risk of tendinitis/tenosynovitis.

Prevalence of pain on palpation of the inferior pole of the patella among patients with complaints of knee pain. Clinics (Sao Paulo) 2009; 64:199-202. [PMID: 19330245 PMCID: PMC2666452 DOI: 10.1590/s1807-59322009000300009] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2008] [Accepted: 11/29/2008] [Indexed: 12/02/2022] Open
Abstract
CONTEXT AND OBJECTIVE Patellar tendinopathy is a common condition in sports. It may occur at any location of the patellar tendon, but the most commonly affected area is the inferior pole of the patella. Among various diagnostic tests, the one most used is palpation of the inferior pole of the patella. The aim of this study was to investigate the prevalence of pain complaints among individuals with pathological knee conditions and to evaluate palpation of the inferior pole of the patella as a diagnostic test for patellar tendinopathy. METHODS Palpation of the patellar tendon was performed on 318 individuals who presented with knee-related complaints. Palpation was performed with the individual in the supine position and the knee extended. The age, gender, physical activity and labor activity of each individual were recorded at the time the symptoms appeared; the diagnosis was also recorded. RESULTS Of the total number of individuals evaluated, 124 (39%) felt pain on palpation of the inferior pole of the patella. Of these, only 40 (32.3%) received a diagnosis of patellar tendinopathy. We did not observe any difference with respect to gender and age distribution. When evaluating daily physical activity levels, however, we observed that individuals with pain on palpation of the inferior pole of the patella experienced more intense physical activity. CONCLUSIONS Palpation of the inferior pole of the patella is a diagnostic procedure with high sensitivity and moderate specificity for diagnosing patellar tendinopathy, especially among individuals who perform activities with high functional demands.
