Management of the Hindfoot and Ankle in Charcot Arthropathy

Neuropathic destabilization of the hindfoot and/or ankle is a significant complication for the patient with diabetes/neuropathy. The loss of ligamentous integrity and bony destruction results in a limb that is not stable for weight bearing. This loss of independence adds significant health risks to the patient. Management of this disease process is both time consuming and technically demanding for both the practitioner and the patient. Attention to detail and aggressive decision making is often necessary to salvage the limb. The goal for treatment is to produce a stable, weight-bearing limb that is shoeable and free from soft-tissue ulceration.

Health-related quality of life and physical activity in Nordic patients with moderate haemophilia A and B (the MoHem study)

INTRODUCTION

The impact of moderate haemophilia on health-related quality of life (HRQoL) and physical activity (PA) is not well known. In previous studies, persons with factor VIII/factor IX activity (FVIII/FIX:C) below 3 IU/dL were associated with a more severe bleeding phenotype than predicted.

AIM

To explore HRQoL and PA in patients with moderate haemophilia A (MHA) and B (MHB).

METHODS

A cross-sectional, multicentre study covering patients with MHA and MHB in Sweden, Finland, and Norway. HRQoL was assessed with the EuroQoL 5-Dimensions (EQ-5D) form and PA with the International Physical Activity Questionnaire among participants aged ≥15 years.

RESULTS

We report on 104 patients aged 15-84 years from the MoHem study. Overall, EQ-5D utility was .85 (median) (Q1-Q3 0.73-1.0) with corresponding visual analogue scale (VAS) 80 (70-90), which were similar regardless of treatment modality, FVIII/FIX:C, and MHA or MHB. Pain and mobility were most frequently affected dimensions. Utility (r = -.54), VAS (r = -.42), and PA (r = -.32) correlated negatively with arthropathy (HJHS). Only patients aged 41-50 years displayed lower utility (p = .02) and VAS (p < .01) than the Norwegian population norm. Patients on prophylaxis aged 35-54 years reported higher PA than those treated on-demand (p = .01).

CONCLUSION

Haemophilic arthropathy had negative impact on HRQoL and PA in Nordic patients with moderate haemophilia. Middle-aged patients captured lower utility and VAS than observed in the general population. Tailored prophylaxis and improved joint health may influence positively on HRQoL and PA also in moderate haemophilia.

A single-centre experience of 29 total ankle replacement in haemophiliac patients: Therapeutic management, factor consumption and cost

INTRODUCTION

In patients with haemophilia, repeated bleeding in large joints leads to chronic haemophilic arthropathy, a rare disease that can be managed surgically with ankle arthrodesis or with total ankle replacement (TAR). TAR has been reported to provide good surgical results in the medium/long-term and allow preservation of joint mobility but the medical therapeutic management of the patients has not been described.

AIM

To describe the medical therapeutic management of TAR.

METHODS

All patients with haemophilia A/B, with haemophilic ankle arthropathy, and who underwent TAR between April 2006 and October 2019 were retrospectively included. Factor consumption, perioperative and early complications, volume of blood lost, and orthopaedic data were collected.

RESULTS

A total of 25 patients underwent 29 TAR (mean age was 44.7 years [range: 26-65]). In the 17 patients with HA without history of anti-FVIII inhibitor, the mean ± SD consumption the day of surgery was 116 ± 16 UI/kg when clotting factors were administered by continuous infusion, 106 ± 13 UI/kg when SHL factors were administered by bolus infusion, and 75 ± 22 UI/kg when EHL factors were administered by bolus infusion. During hospitalisation, the mean factor cost was €38,073 (83.7% of the total cost of surgery). Mean blood loss was significantly lower in patients treated with tranexamic acid (164 mL, range: 40-300) than in those not (300 mL, range: 70-800; p = .01). Six patients had haematoma. The 10-year survival free of any prosthesis removal/arthrodesis was estimated to be 92.2% (95% CI [83; 100]).

CONCLUSION

The medical therapeutic management of TAR is complex, carried out by a multidisciplinary team but effective in avoiding the occurrence of complications.

Diabetes mellitus-related musculoskeletal disorders: Unveiling the cluster of diseases

The current study ushers in a comprehensive review in clinical research to demonstrate the prevalence of musculoskeletal (MSK) complications in diabetes mellitus and the most relevant clinical aspects. In particular, revealing the early symptoms of the disorders, the pathology lurking behind the complications and their optimal management. In diabetes mellitus, MSK complications are common and are largely due to similar pathogenetic factors responsible for the internal organ complications associated with diabetes leading to chronic low-intensity inflammatory processes. MSK disorders develop by vasculopathy, neuropathy, arthropathy or combinations of the above, which are not specific to diabetes. However, their prevalence is significantly increased in diabetes and contributes to the disability impairing patients' quality of life. Locomotor disease affects approximately 34.4-83.5 % of patients suffering from type-2 diabetes mellitus. Several musculoskeletal abnormalities (cheiroarthropathy, Dupuytren's contracture, trigger finger, ect.) can be diagnosed upon physical examination, although certain symptoms (frozen shoulder, neurogenic arthropathy, septic arthritis, etc.) require differential diagnostic considerations. Early identification regarding characteristic symptoms in the treatment reducing inflammation and pain, followed with increasingly strenuous exercise therapy, aligned with optimal management of carbohydrate metabolism, proves essential in alleviating MSK complications.

Physical therapy for end-stage hemophilic arthropathy: a case report

This report introduces a young adult who has been in bed for more than ten years with end-stage hemophilic arthropathy. He didn't have access to factor VIII (FVIII) in the early stage of hemophilia due to the high costs of clotting replacement therapy. As a result, he is experiencing some difficulties, such as joint contracture, muscular atrophy, severe pain, and poor function of cardiopulmonary. He came to visit us for a comprehensive rehabilitation program, and, finally, he achieved the basic goal of self-care in daily life.

Joint status, pain and quality of life in elderly people with haemophilia: A case-control study

INTRODUCTION

Elderly people with haemophilia (PwH) develop haemophilic arthropathy, pain, and reduced health-related quality of life (HR-QoL). The condition of elderly mild haemophilia patients have rarely been evaluated. This study aimed to compare joint status, pain, and HR-QoL between elderly with mild, moderate/severe haemophilia and healthy elderlies.

METHODS

Knee/ankle abnormalities were assessed by ultrasound (HEAD-US) and physical examination (HJHS 2.1). Pain severity and pain interference were investigated using the Brief Pain Inventory. Pressure pain thresholds (PPTs) were obtained at knees/ankles and forehead. Functional limitations were evaluated using the 2-Minute-Walking-Test, Timed-Up-and-Go and HAL. The EQ-5D-5L questionnaire evaluated HR-QoL. Healthy controls (HCs) and elderly individuals with moderate/severe and mild haemophilia were compared using Kruskal-Wallis and Mann-Whitney U tests.

RESULTS

From the 46 elderly PwH approached, 40 individuals (≥60 years) with haemophilia A/B (17 moderate/severe; 23 mild) and 20 age-matched HCs were recruited. Moderate/severe PwH displayed worse joint status, lower PPTs, and poorer HR-QoL than mild PwH and HCs (p-value = .010-<.001). HEAD-US abnormalities were observed in 100% of knees and 94% of ankles in moderate/severe PwH, versus 50% of knees and 61% of ankles in mild PwH. Pain was reported by 80% and 57% of moderate/severe and mild PwH, respectively. Low PPTs, functional limitations, and poor HR-QoL scores were likewise observed in some mild PwH, yet without significantly differing from HCs.

CONCLUSION

This study highlights poor joint/functional status, pain, and HR-QoL outcomes in elderly with moderate/severe haemophilia. A few mild haemophilia subjects presented joint abnormalities, pain, functional limitations, and poor HR-QoL, without significantly differing from HCs.

HIGHLIGHTS

Elderly individuals with mild haemophilia have not yet been extensively studied, whereas moderate/severe haemophilia individuals have proven to suffer from haemophilic arthropathy, pain, and poor health-related quality of life (HR-QoL). Using a case-control design, joint status, pain, and HR-QoL outcomes were examined in elderly haemophilia individuals and compared with those of healthy controls (HCs). Elderly moderate/severe haemophilia individuals exhibited worse joint status, increased joint pain sensitivity, and reduced HR-QoL compared with both mild haemophilia subjects and HCs. A subset of mild haemophilia subjects exhibited poor joint status, pain, and HR-QoL outcomes, without any differences noted when compared with HCs.

How does joint impairment affect the functional capacity of the lower limb in early haemophilia-related arthropathy?

INTRODUCTION

The impact of joint damage on functional capacity in patients with mild haemophilia (PwMH) has yet to be well studied. The primary aim of this study was to investigate the effect of joint impairment on the functional capacity of the lower limb in PwMH. The secondary aim was to identify physical predictors of lower limb functional capacity.

METHOD

Forty-nine PwMH were evaluated. Dynamic balance was assessed using Time Up and Go (TUG). Thirty-second sit-to-stand (30-STS) and 60-second-STS (60-STS) were used to assess muscle power and endurance, respectively. Haemophilia Early Arthropathy Detection with Ultrasound (HEAD-US) was used to assess joint damage. PwMH were divided based on HEAD-US: with joint damage (≥3 points) and without or with very low joint damage (0-2 points). Univariate ANOVA and multiple regression analyses were performed to identify differences in functional capacity and potential physical predictors.

RESULTS

Only 30-STS showed significant differences between groups (p = .002). TUG and 60-STS were primarily explained by age (r2  = .21 and r2  = .44, respectively), while for 30-STS, age combined with joint damage and pain level explains 54% of the variance.

CONCLUSION

Our findings indicate that the 30-STS is useful for assessing functional deterioration in people with early-stage haemophilia-related arthropathy. Our results also indicate that joint damage, combined with ageing and pain, may impact 30-STS outcomes in PwMH. Furthermore, our findings show that the loss in TUG and 60-STS performance in PwMH is related to ageing.

Evaluation of Functional and Joint Health and Associated Factors in Adults With Hemophilia From a Developing Country With Government-Backed Efforts to Improve Hemophilia Care

Introduction Hemophilic arthropathy affects people with hemophilia (PwH) and causes joint dysfunction and disability. Brazil has a unique situation and implemented policies to improve health care for PwH. The aim of this study was to evaluate the Functional Independence Score in Hemophilia (FISH), Hemophilia Joint Health Score (HJHS), and associated factors among adult PwH attending a Hemophilia Comprehensive Care Center in Brazil. Methods A post hoc analysis was conducted, including 31 patients who had submitted to a physical evaluation during a previously published cross-sectional study performed from June 2015 to May 2016 at the Brasília Blood Center Foundation, Brazil. Results The mean age was 30.8±9.4 years, and 80.6% had severe hemophilia. FISH was 27.0±3.8, and HJHS 18.0±10.8. The ankle was the most often affected joint (25/31, 80.6%). There were significant correlations between FISH and HJHS scores and the Hemophilia Quality of Life Questionnaire for Adults. Patients with severe hemophilia (P = 0.029) and PwH aged ≥ 30 years (P = 0.049) had lower FISH scores. Monthly household income > 2 Brazilian minimum wages was independently associated with improved HJHS (P = 0.033). The factors simultaneously associated with better HJHS and FISH were age < 30 years (P = 0.021) and monthly household income < 2 minimum wages (P = 0.013). Conclusion FISH and HJHS showed favorable scores despite being performed in a country with unfavorable socioeconomic conditions. In addition to hemophilia severity and age, monthly household income was independently associated with functional and articular state of PwH. The results highlight the importance of the free provision of coagulation factors in Brazil.

Age-specific incidence of joint disease in paediatric patients with haemophilia: A single-centre real-world outcome based on consecutive US examination

INTRODUCTION

Joint health is one of the most important factors contributing to a healthy life in patients with haemophilia. Recent study revealed that starting early prophylaxis was not enough to prevent joint disease in most paediatric patients with haemophilia.

AIM

In this study, we aimed to determine the age-specific incidence of acute joint disease during childhood at single haemophilia treatment centre (HTC).

METHOD

The joint health in 48 patients was evaluated based on consecutive US testing for 5 years at annual multidisciplinary comprehensive care.

RESULTS

During the study period, 23 patients (47.9%) had no joint disease since the initial examination, whereas 13 patients (27.0%) showed development from negative to positive findings. The incidence of joint disease increased with age: 0% in preschool, 5.3% in elementary school, 14.3% in junior high school and 35% beyond high school age. Among the 13 patients who developed joint disease, two experienced acquired synovitis that resolved during the follow-up period. Statistical analysis revealed that the patients who routinely underwent follow-up by the HTC exhibited a significantly lower incidence of joint disease than did those followed up at other institutions (p < .001).

CONCLUSION

These results indicated that close check-up, including routine joint examination using US as well as frequent assessment of pharmacokinetic profile at the HTC, might play an important role in avoiding joint disease among paediatric patients with haemophilia.

[Impact of surgical treatment of morbid obesity on joint diseases]

The prevalence of obesity in the modern world is increasing. Obesity is an independent risk factor for some rheumatic diseases and also worsens their course. The presence of chronic joint disease can make it difficult for obesity to reduce activity, creating a vicious circle where joint pain makes exercise difficult and being overweight exacerbates joint pain. At the same time, there is a conditionally radical method of treating obesity - bariatric surgery (BS), which is currently used when conservative methods are ineffective. The purpose of this review is to analyze the data presented in the world literature on the impact of BS on the course of the most common rheumatic diseases. The available data show the possibility of a positive effect of BS not only on weight loss, but also on the course of a number of rheumatic diseases.

No Difference in Risk of Amputation or Frequency of Surgical Interventions Between Patients With Diabetic and Nondiabetic Charcot Arthropathy

BACKGROUND

The cause of Charcot neuro-osteoarthropathy (CN) is diabetes in approximately 75% of patients. Most reports on the clinical course and complications of CN focus on diabetic CN, and reports on nondiabetic CN are scarce. No study, to our knowledge, has compared the clinical course of patients initially treated nonoperatively for diabetic and nondiabetic CN.

QUESTIONS/PURPOSES

Among patients with CN, are there differences between patients with diabetes and those without in terms of (1) the frequency of major amputation as ascertained by a competing risks survivorship estimator; (2) the frequency of surgery as ascertained by a competing risks survivorship estimator; (3) frequency of reactivation, as above; or (4) other complications (contralateral CN development or ulcers)?

METHODS

Between January 1, 2006, and December 31, 2018, we treated 199 patients for diabetic CN. Eleven percent (22 of 199) were lost before the minimum study follow-up of 2 years or had incomplete datasets and could not be analyzed, and another 9% (18 of 199) were excluded for other prespecified reasons, leaving 80% (159 of 199) for analysis in this retrospective study at a mean follow-up duration since diagnosis of 6 ± 4 years. During that period, we also treated 78 patients for nondiabetic Charcot arthropathy. Eighteen percent (14 of 78) were lost before the minimum study follow-up and another 5% (four of 78 patients) were excluded for other prespecified reasons, leaving 77% (60 of 78) of patients for analysis here at a mean of 5 ± 3 years. Patients with diabetic CN were younger (59 ± 11 years versus 68 ± 11 years; p < 0.01), more likely to smoke cigarettes (37% [59 of 159] versus 20% [12 of 60]; p = 0.02), and had longer follow-up (6 ± 4 years versus 5 ± 3 years; p = 0.02) than those with nondiabetic CN. Gender, BMI, overall renal failure, dialysis, and presence of peripheral arterial disease did not differ between the groups. Age difference and length of follow-up were not considered disqualifying problems because of the later onset of idiopathic neuropathy and longer available patient follow-up in patients with diabetes, because our program adheres to the follow-up recommendations suggested by the International Working Group on the Diabetic Foot. Treatment was the same in both groups and included serial total-contact casting and restricted weightbearing until CN had resolved. Then, patients subsequently transitioned to orthopaedic footwear. CN reactivation was defined as clinical signs of the recurrence of CN activity and confirmation on MRI. Group-specific risks of the frequencies of major amputation, surgery, and CN reactivation were calculated, accounting for competing events. Group comparisons and confounder analyses were conducted on these data with a Cox regression analysis. Other complications (contralateral CN development and ulcers) are described descriptively to avoid pooling of complications with varying severity, which could be misleading.

RESULTS

The risk of major amputation (defined as an above-ankle amputation), estimated using a competing risks survivorship estimator, was not different between the diabetic CN group and nondiabetic CN group at 10 years (8.8% [95% confidence interval 4.2% to 15%] versus 6.9% [95% CI 0.9% to 22%]; p = 0.4) after controlling for potentially confounding variables such as smoking and peripheral artery disease. The risk of any surgery was no different between the groups as estimated by the survivorship function at 10 years (53% [95% CI 42% to 63%] versus 58% [95% CI 23% to 82%]; p = 0.3), with smoking (hazard ratio 2.4 [95% CI 1.6 to 3.6]) and peripheral artery disease (HR 2.2 [95% CI 1.4 to 3.4]) being associated with diabetic CN. Likewise, there was no between-group difference in CN reactivation at 10 years (16% [95% CI 9% to 23%] versus 11% [95% CI 4.5% to 22%]; p = 0.7) after controlling for potentially confounding variables such as smoking and peripheral artery disease. Contralateral CN occurred in 17% (27 of 159) of patients in the diabetic group and in 10% (six of 60) of those in the nondiabetic group. Ulcers occurred in 74% (117 of 159) of patients in the diabetic group and in 65% (39 of 60) of those in the nondiabetic group.

CONCLUSION

Irrespective of whether the etiology of CN is diabetic or nondiabetic, our results suggest that orthopaedic surgeons should use similar nonsurgical treatments, with total-contact casting until CN activity has resolved, and then proceed with orthopaedic footwear. A high frequency of foot ulcers must be anticipated and addressed as part of the treatment approach.

LEVEL OF EVIDENCE

Level III, prognostic study.

[Hypogonadism syndrome in men with inflammatory joint diseases: A review]

Most rheumatic diseases are characterized by sexual dimorphism both in prevalence and in the characteristics of the clinical course. Increased production of pro-inflammatory cytokines that accompanies inflammatory joint diseases may be accompanied by a decrease in the level of male sex hormones, and vice versa, the presence of hypogonadism in men increases the risk of developing certain rheumatic diseases. The review presents data on the relationship between testosterone deficiency and major inflammatory joint diseases, as well as the effect of testosterone replacement therapy on their manifestations.

Effects of millimeter-wave for preventing joint stiffness in the immobilized knee rat model

AIM

To explore the effects and mechanism of millimeter-wave treatment on the development of joint stiffness in the immobilized knee rat model.

METHODS

Twenty-four Sprague-Dawley (SD) rats were randomly divided into the control group (O, n = 8), the surgical control group (OC, n = 8), and the millimeter-wave treatment group (MO, n = 8). After immobilized knee modeling, the knee mobility and quadriceps diameter was measured at the 6th week. Hematoxylin and eosin and Masson staining were performed to detect the pathology and fibrous lesions of the knee joint. Furthermore, the expression of TGF-β1 and Collagen I was quantified by immunohistochemical assay in the knee capsule, and Western blotting was performed to quantify the protein expression of NF-κB and MuRF1 in skeletal muscle.

RESULTS

Compared with the O group, knee mobility, and quadriceps diameter was decreased (P < 0.01), and articular capsule fibrosis and quadriceps atrophy occurred in all rats with fixed knee joints. Compared with the OC group, millimeter-wave treatment significantly increased articular mobility and the quadriceps diameter; and improved the fibrotic lesions of the joint capsule and quadriceps atrophy. Moreover, levels of TGF-β1, Collagen I, and MuRF1 were upregulated (P < 0.01) by knee immobilization, and collagen fiber content in the articular capsule was also increased (P < 0.01). However, millimeter-wave treatment reversed it. The most noteworthy result was that NF-κB expression was not significantly different in all groups.

CONCLUSION

Millimeter-wave treatment reversed joint contracture and quadriceps atrophy caused by joint fixation, inhibited TGF-β1 and Collagen I protein expression of the joint capsule and reduced MuRF1 expression of the quadriceps muscle, thereby inhibiting the development of joint stiffness.

The Correlation Between the HEAD-US-C Score and HJHS in Hemophilic Arthropathy of the Knee

OBJECTIVES

We aimed to discuss the correlation between the Hemophilia Early Detection Ultrasound in China (HEAD-US-C) score and the Hemophilia Joint Health Score version 2.1 (HJHS 2.1) of the knee joint in patients with hemophilia.

METHODS

We included 70 male patients with hemophilia admitted to The Second Hospital of Shanxi Medical University; the patients' bilateral knee joints were evaluated using the HEAD-US-C score and HJHS. We analyzed factors influencing hemophilia arthropathy of the knee and examined the correlation between the HEAD-US-C score and HJHS.

RESULTS

The joint injury severity was positively correlated with age and the number of bleeds (P < .001). Further, the HEAD-US-C score and HJHS differed according to the severity (both P < .001), but not type (P = .163 and P = .283, respectively), of hemophilia. There was a significant correlation between the HEAD-US-C score and HJHS (P < .001).

CONCLUSIONS

Overall, all joint lesions observed on ultrasound corresponded to clinical joint functional abnormalities. Therefore, the HEAD-US-C is important for hemophilic arthropathy evaluation and is useful in explaining abnormal joint function.

Psychological complications in patients with acromegaly: relationships with sex, arthropathy, and quality of life

PURPOSE

Current treatment of acromegaly restores a normal life expectancy in most cases. So, the study of persistent complications affecting patients' quality of life (QoL) is of paramount importance, especially motor disability and depression. In a large cohort of acromegalic patients we aimed at establishing the prevalence of depression, to look for clinical and sociodemographic factors associated with it, and to investigate the respective roles (and interactions) of depression and arthropathy in influencing QoL.

METHODS

One hundred and seventy-one acromegalic patients (95 women and 76 men, aged 20-85 years) among those recruited in a cross-sectional Italian multicentric study were investigated. Each patient filled in three validated questionnaires: AcroQoL, WOMAC (measuring articular pain, stiffness and functionality), and AIMS (evaluating articular symptoms and depression).

RESULTS

A very high (up to 28%) depression rate was detected in acromegalic subjects. Two patients showing pathological AIMS depression scores, committed suicide during the three years observational period. In our population poor psychological status was significantly associated with female sex. Furthermore, a significant strong correlation was found between AIMS depression score and WOMAC score. Both depression and arthropathy-related motor disability turned out to independently contribute with similar strength to the impairment of QoL.

CONCLUSIONS

We report a high prevalence of depression in acromegaly, which is associated with female sex and arthropathy. Both depression and arthropathy strongly and independently contribute to the impaired QoL of patients. Our study shows that assessment and monitoring of psychological status is mandatory in acromegaly, also suggesting an inexpensive tool for this assessment.

EFFECT OF THE COMBINED UTILIZATION OF STATIC PROGRESSIVE STRETCHING AND PHONOPHORESIS WITH HYDROCORTISONE IN REHABILITATION OF KNEE CONTRACTURES CAUSED BY ARTHROFIBROSIS

Arthrofibrosis is the abnormal proliferation of fibrous tissue in a joint with an unclear etiopathogenesis that leads to loss of motion, pain, muscle weakness, swelling, and functional limitation. Various methods of therapy are utilized to treat the aforementioned pathology and among them are also aggressive approaches such as static progressive stretching. The goal of the current study was to establish the superiority of the effect of the combined utilization of static progressive stretching and hydrocortisone phonophoresis over standard therapeutic exercise programs for the rehabilitation process of knee contractures caused by arthrofibrosis. 29 patients between the ages of 18 and 60 (mean age 42±4.3 y.o.) participated in the prospective randomized controlled study, 19 male (65%) and 10 female (35%) with clinical signs of type III and IV contracture of the knee, extension limitation ˃10° and flexion deficit ˃25° when compared to the uninjured side. A minimum of 3 months had passed since the initial injury or the surgical intervention in all cases. 10 male and 5 female patients were randomly distributed to Group I (experimental group) while 9 male and 5 female patients were distributed into Group II (control group) accordingly. The patients from Group I underwent a 2-week long treatment course (10 procedures) with highly concentrated (10%) hydrocortisone phonophoresis before the inception of the standard rehabilitation program while the patients from Group II went through a rehabilitation course consisting solely of static progressive stretching and a home exercise program. The effect of static progressive stretching in the rehabilitation process of knee contractures caused by arthrofibrosis is greatly improved after the utilization of ultraphonophoresis with highly concentrated hydrocortisone alongside standard home exercise programs and this effect is especially apparent in the cases of patients with type III arthrofibrosis and knee flexion contractures.

Magnetic Resonance Imaging-Assessed Subchondral Cysts and Incident Knee Pain and Knee Osteoarthritis: Data From the Multicenter Osteoarthritis Study

OBJECTIVE

To examine whether knee subchondral cysts, measured on magnetic resonance imaging (MRI), are associated with incident knee osteoarthritis (OA) outcomes.

METHODS

We used longitudinal data from the Multicenter Osteoarthritis Study, a community-based cohort of subjects with risk factors for knee OA. Participants without a history of knee surgery and/or inflammatory arthritis (i.e., rheumatoid arthritis and gout) were followed up for 84 months for the following incident outcomes: 1) radiographic knee OA (Kellgren/Lawrence grade ≥2), 2) symptomatic radiographic knee OA (radiographic knee OA and frequent knee pain), and 3) frequent knee pain (with or without radiographic knee OA). In a subset of participants, subchondral cysts were scored on baseline MRIs of 1 knee. Multiple logistic regression, with adjustment for participant characteristics and other baseline knee MRI findings, was used to assess whether subchondral cysts were predictive of incident outcomes.

RESULTS

Among the participants with knees eligible for analyses of outcomes over 84 months, incident radiographic knee OA occurred in 22.8% of knees with no baseline radiographic knee OA, symptomatic radiographic knee OA occurred in 17.0% of knees with no baseline symptomatic radiographic knee OA, and frequent knee pain (with or without radiographic knee OA) occurred in 28.8% of knees with no baseline radiographic knee OA and 43.7% of knees with baseline radiographic knee OA. With adjustment for age, sex, and body mass index, the presence of subchondral cysts was not associated with incident radiographic knee OA but was associated with increased odds of incident symptomatic radiographic knee OA (odds ratio 1.92 [95% confidence interval 1.16-3.19]) and increased odds of incident frequent knee pain in those who had radiographic knee OA at baseline (odds ratio 2.11 [95% confidence interval 0.87-5.12]). Stronger and significant associations were observed for outcomes based on consistent reports of frequent knee pain within ~1 month of the study visit.

CONCLUSION

Subchondral cysts are likely to be a secondary phenomenon, rather than a primary trigger, of radiographic knee OA, and may predict symptoms in knees with existing disease.

Musculoskeletal manifestations in Alkaptonuria: A cross-sectional study

This study aimed to determine the patient characteristics and clinical presentation of Alkaptonuria cases reported by the Biochemical Genetics Lab.An observational study was conducted at the Biochemical Genetics Lab. Alkaptonuria patients were diagnosed based on the homogentisic acid peak in urine and their demographics and clinical data collected from to 2013 to 2019. Clinical history related to joint diseases, ochronotic presentation, and urine darkening on standing was collected.During 7 years, 21 Alkaptonuria cases were reported from BGL; mean age 19.4 ± 24.5 years (range 0.2-66 years) and male to female ratio of 2:1. Of the total, only 9 were adults (mean age, 44 ± 12 years). Most adult patients had musculoskeletal involvement, with joint pain (n = 9) and ochronotic pigmentation (n = 6), whereas all patients presented with a history of urine darkening on standing (21/21 cases).The high prevalence of musculoskeletal involvement observed in patients with albuminuria is likely to be missed by physicians unless specifically tested for in such cases.

Shoulder arthropathy secondary to syringomyelia: case series of 10 patients

PURPOSE

Neuroarthropathy is a progressive joint degeneration secondary to neurological diseases. In the upper extremity, the shoulder is the most exposed, and it is mainly caused by syringomyelia. This condition is rare; therefore, the literature has documented only a few case reports or case series of small groups of patients.

METHODS

We collected data about patients with shoulder arthropathy due to syringomyelia who were treated in our two institutes and collected among members of the Polish Shoulder and Elbow Society. Our analysis was based on epidemiological data, symptoms, and clinical examinations. We also examined the results of diagnostic tests, including-spinal cord MRI and shoulder X-ray, and treatment methods and their effectiveness.

RESULTS

The examined group included 10 women with an average age of 63 years. Of these, nine patients reported pain, seven reported-swelling, and nine reported-weakness. In every patient, diagnosis was confirmed by X-ray of the shoulder with joint degeneration and MRI of the spinal cord with syrinx. Two patients were operated with reverse shoulder arthroplasty; the first one had excellent result-significant active range of motion improvement and reduction of symptoms, and the second one had a good result-pain relief and moderate range of motion improvement. Other patients were conservatively treated, resulting in total or partial symptoms relief but without significant range of motion improvement.

CONCLUSION

Charcot shoulder secondary to syringomyelia was mainly manifested by range of motion limitation, swelling, and pain. Both conservative and surgical treatments could be a good solution. However, if reverse arthroplasty is technically possible, it seems to be the most promising treatment for recovering function.

Robenacoxib shows efficacy for the treatment of chronic degenerative joint disease-associated pain in cats: a randomized and blinded pilot clinical trial

The main objective of this pilot clinical trial was to evaluate outcome measures for the assessment of the nonsteroidal anti-inflammatory drug (NSAID) robenacoxib in cats with degenerative joint disease-associated pain (DJD-pain). Otherwise healthy cats (n = 109) with DJD-pain entered a parallel group, randomized, blinded clinical trial. Cats received placebo (P) or robenacoxib (R) for two consecutive 3-week periods. Treatment groups were PP, RR, and RP. Actimetry and owner-assessment data were collected. Data were analyzed using mixed-effects and generalized mixed-effects linear models. Activity data showed high within-cat and between-cat variability, and 82.4% of the values were zero. Compared to placebo, mean total activity was higher (5.7%) in robenacoxib-treated cats (p = 0.24); for the 80th percentile of activity, more robenacoxib-treated cats had a > 10% increase in activity after 3 (p = 0.046) and 6 weeks (p = 0.026). Robenacoxib treatment significantly decreased owner-assessed disability, (p = 0.01; 49% reduction in disability; effect size ~ 0.3), and improved temperament (p = 0.0039) and happiness (p = 0.021) after 6 weeks. More robenacoxib-treated cats were successes at 6 weeks (p = 0.018; NNT: 3.8). Adverse effect frequencies were similar across groups. Results identified suitable endpoints for confirmatory studies, while also indicating efficacy of robenacoxib in cats with DJD-pain.

[Clinical Features of Relapsing Polychondritis Patients Presented with Arthropathy]

Objective To explore the clinical characteristics of relapsing polychondritis(RP)patients presented with arthropathy. Methods We retrospectively analyzed the clinical data of 201 RP patients who were hospitalized in our center between December 2005 and February 2019.After 16 patients with co-existing other autoimmune diseases and malignancies were ruled out,185 RP patients entered the final analysis,among whom 16 RP patients were presented with arthropathy and 169 without arthropathy.The demographic data,clinical manifestations,laboratory findings,and prognosis were compared between these two groups. Results Five of the 16 RP patients with arthropathy at presentation were misdiagnosed as rheumatoid arthritis.Compared with RP patients without arthropathy at presentation,RP patients with arthropathy at presentation had a longer disease course[(37.50±66.50)months vs.(9.00±11.00)months,z=-3.186,P =0.001],longer time of diagnostic delay[(24.00±41.25)months vs.(7.00±9.00)months,z=-2.890,P=0.004],and higher incidence of eye(62.50% vs. 36.09%,χ²=4.309,P=0.038)and nervous system involvements(43.75% vs. 15.38%,χ²=6.205,P=0.013). Conclusions RP patients with arthropathy at presentation are most likely to be misdiagnosed as rheumatoid arthritis.These patients are characterized by longer disease course and diagnostic delay and more frequrent eye and nervous system involvements.

Arthroscopic treatment of a lipoma arborescens of the elbow: A case report

INTRODUCTION

Lipoma Arborescens is a rare pathology that mainly affects the knee. Occurrences in the elbow are even more uncommon and mainly involve the bicipitoradial bursa.

CASE'S DESCRIPTION

We describe the case of a 54-year-old patient known for rheumatoid arthritis, who consulted for chronic elbow pain associated with swelling and limited extension.

DIAGNOSIS

The diagnosis of a lipoma arborescens of the elbow involving the whole joint was made using magnetic resonance imaging and confirmed during arthroscopy.

INTERVENTIONS

After a failed nonoperative treatment consisting in intra-articular cortisone injections and physiotherapy, the patient underwent arthroscopic synovectomy and arthrolysis.

OUTCOME

At 1-year follow-up, he reported no pain, satisfactory range of motion, and major improvements in clinical scores.

CONCLUSION

This is the first illustrated case report about lipoma arborescens involving the whole elbow joint. Even though it is a rare disease, awareness of its presentation, imaging patterns, and treatment options is therefore important for clinicians, radiologists, and surgeons. In this case, arthroscopic treatment resulted in satisfactory and long-lasting pain relief and functional results. It may be considered as a safe and effective option in case of failed nonoperative measures.

Chronic pain in patients with hemophilia: is it preventable?

: Current management of chronic pain in patients with hemophilia (PWH) focuses on pain relief with analgesics and symptom control. The clinical practice of managing chronic pain in PWH varies considerably across hemophilia treatment centers. Here, we aim to study the appropriate intervention of hemophilic arthropathy for prevention and treatment of chronic pain in PWH. Medline, Embase, Cochrane databases were searched for randomized controlled trials, and the European Hemophilia Therapy Standardization Board, The World Federation of Hemophilia, Nordic Hemophilia Guidelines, American Society of the International Pain Physicians and the Medical and Scientific Advisory Council guidelines were studied through November 2019 for chronic pain in PWH for a narrative review. We found no standardized approach for the prevention and management of chronic pain in PWH. Evidence suggests that prophylactic factor concentrate therapy, programmed exercise and educational intervention may help PWH manage their chronic pain.

Low Dose Radiation Therapy, Particularly with 0.5 Gy, Improves Pain in Degenerative Joint Disease of the Fingers: Results of a Retrospective Analysis

Low-dose radiation therapy (LDRT) has been successfully established for decades as an alternative analgesic treatment option for patients suffering from chronic degenerative and inflammatory diseases. In this study, 483 patients were undergoing LDRT for degenerative joint disease of the fingers and thumb at the University Hospital Erlangen between 2004 and 2019. Radiotherapy was applied according to the German guidelines for LDRT. Several impact factors on therapeutic success, such as the age and gender, the number of affected fingers, the single and cumulative dose, as well as the number of series, were investigated. In summary, 70% of the patients showed an improvement of their pain following LDRT. No significant impact was found for the factors age, gender, the number of series or the cumulative dosage. Patients with an involvement of the thumb showed a significantly worse outcome compared to patients with an isolated affection of the fingers. In this cohort, patients receiving a single dose of 0.5 Gy reported a significantly better outcome than patients receiving 1.0 Gy, strongly suggesting a reduction in the total dose. In summary, LDRT is a good alternative treatment option for patients suffering from degenerative and inflammatory joint disease of the fingers.

Physiotherapists' ability to diagnose and manage shoulder disorders in an outpatient orthopedic clinic: results from a concordance study

BACKGROUND

Advanced practice physiotherapy has emerged as a promising solution to improve health care access because access to orthopedic care is limited in several countries. However, evidence supporting advanced practice physiotherapy models for the management of shoulder pain remains scarce. The purpose of this study was to establish diagnostic, surgical triage, and medical imaging agreement between advanced practice physiotherapists (APPs) and orthopedic surgeons (OSs) for the management of patients with shoulder disorders in an outpatient orthopedic clinic.

METHODS

Patients referred to an OS for shoulder complaints were recruited and independently assessed by an OS and an APP. Each provider completed a standardized form indicating diagnosis, imaging test requests, and triage of surgical candidates. Patient satisfaction with care was recorded with the 9-item Visit-Specific Satisfaction Questionnaire (VSQ-9). Inter-rater concordance was calculated with the Cohen κ, prevalence-adjusted bias-adjusted κ, and associated 95% confidence interval (CI). We used χ² tests to compare differences between providers in terms of treatment plan options and Student t tests to compare patient satisfaction between providers.

RESULTS

Fifty participants were evaluated. Good diagnostic agreement was observed between providers (κ, 0.80; 95% CI, 0.67-0.93). Agreement for triage of surgical candidates was moderate (κ, 0.46; 95% CI, 0.21-0.71) as APPs tended to refer patients more often to OSs for further evaluation. Imaging test request agreement was moderate as well (κ, 0.42; 95% CI, 0.19-0.66). Patient satisfaction with care was high, with no significant differences found between providers (P = .70).

CONCLUSION

APPs could improve access to orthopedic care for shoulder disorders by safely initiating patient care without compromising satisfaction. These results support further development and evaluation of APP care for orthopedic patients presenting with shoulder disorders.

Opioid Use Disorder Is Associated with an Increased Risk of Infection after Total Joint Arthroplasty: A Large Database Study

BACKGROUND

Recent studies have shown that patients with opioid use disorder have impaired immunity. However, few studies with large patient populations have evaluated the risks of surgical site infection (SSI) and prosthetic joint infection (PJI) with opioid use disorder after total joint arthroplasty (TJA), and there is a lack of evidence for revision TJA in particular.

QUESTIONS/PURPOSES

Are patients with opioid use disorder who undergo (1) primary THA, (2) primary TKA, (3) revision THA, or (4) revision TKA at a higher risk of experiencing SSIs 90 days after surgery or PJIs 2 years after surgery than those who do not have opioid use disorder?

METHODS

All primary and revision TJAs performed between 2005 and 2014 were identified from the Medicare Analytical Files of the PearlDiver Supercomputer using ICD-9 codes. This database is one of the largest nationwide databases; it comprehensively and longitudinally tracks patients based on all insurance claims rather than particular hospital visits, and has a low error rate (estimated at 1.3%). Boolean command operators were used to form a study group of patients with a history of opioid use disorder before surgery. ICD-9 diagnosis codes 304.00 to 304.02 and 305.50 to 305.52 were used to identify patients with opioid use disorder. Study group patients were matched 1:1 to control participants without opioid use disorder undergoing TJA, according to age, sex, and comorbidity burden (Elixhauser comorbidity index [ECI]). The ECI is comprised of 31 different comorbidities and can be used for large administrative databases. The query yielded a study population of 54,332 patients: 14,944 undergoing primary THA (opioid use disorder: n = 7472), 23,680 undergoing primary TKA (opioid use disorder: n = 11,840), 8116 undergoing revision THA (opioid use disorder: n = 4058), and 7592 undergoing revision TKA (opioid use disorder: n = 3796). The primary outcomes analyzed were SSI at 90 days and PJI at 2 years postoperatively, which were identified with ICD-9 codes. Logistic regression analyses were performed to calculate the risk that an infection would develop in a patient with opioid use disorder compared with the matched control patients without opioid use disorder.

RESULTS

Patients with opioid use disorder undergoing primary THA had an increased risk of SSI at 90 days (OR 1.85 [95% CI 1.51 to 2.25]; p < 0.001) and PJI at 2 years (OR 1.66 [95% CI 1.42 to 1.93]; p < 0.001). Compared with matched controls, opioid use disorder patients undergoing primary TKA had an increased risk of SSI at 90 days (OR 1.72 [95% CI 1.46 to 2.02]; p < 0.001) and PJI at 2 years (OR 1.31 [95% CI 1.16 to 1.47]; p < 0.001). Similarly, for revision THAs, there was an increase in 90-day SSIs (OR 1.89 [95% CI 1.53 to 2.32]; p < 0.001) and 2-year PJIs (OR 4.24 [95% CI 3.67 to 4.89]; p < 0.001). The same held for revision TKAs for 90-day SSIs (OR 1.88 [95% CI 1.53 to 2.29]; p < 0.001) and 2-year PJIs (OR 4.94 [95% CI 4.24 to 5.76]; p < 0.001).

CONCLUSIONS

After accounting for age, sex, and comorbidity burden, these results revealed that patients with opioid use disorder undergoing TJA were at increased risk of having SSIs and PJIs. Based on these findings, healthcare systems and/or administrators should recognize the increased associated PJI and SSI risks in patients with opioid use disorder and enact clinical policies that reflect these associated risks. Additionally, these findings should encourage surgeons to pursue multidisciplinary approaches to help patients reduce their opioid consumption before their arthroplasty procedure.

Common peroneal nerve 'pre-release' in total knee arthroplasty for severe valgus deformities

BACKGROUND

Common peroneal nerve (CPN) palsy is a devastating complication that follows total knee arthroplasty (TKA). However, there are only a few studies on concrete measures for protecting the CPN in patients. This study aimed to put forward the CPN 'pre-release' method to protect the nerve.

METHODS

A prospective study was conducted on 30 patients (34 knees) with severe valgus knees who underwent CPN pre-release. This was a two-incision approach, and required a separate dissection of about three centimeters from the TKA operation. Clinical measurements including pre- and postoperative motor and sensory nerve function of CPN, radiological evaluation, complications, and the revised data were analyzed and compared.

RESULTS

The average preoperative femorotibial angle was 31.3 ± 8.0°. All patients had completely normal motor (grade 5) and sensory nerve function of CPN postoperatively, and there was no transient or late-onset CPN palsy. Patients had a routine rehabilitation with full weight bearing after recovery from anesthesia, including the knees with unconstrained extension/flexion motion. During the last follow-up visit, the visual analog scale, Knee Society Score, Hospital for Special Surgery knee-rating scale, and range of motion were 2.06 ± 1.13, 92.18 ± 5.57, 90.18 ± 3.70, and 115.59 ± 7.76°, respectively. There were no revisions for instability and recurrent valgus deformities during follow-up. Also, the femorotibial angle, hip-knee-ankle angle, condylar-hip angle, and plateau-ankle angle were 4.9 ± 2.0°, 179.09 ± 3.21°, 89.97 ± 2.41°, and 90.53 ± 1.26°, respectively.

CONCLUSIONS

The CPN pre-release for severe valgus knees is an effective method for nerve protection, achieving an adequate and safe release of lateral soft tissue, and providing immediate and early functional rehabilitation with decreasing constrained implant.

Optimizing leg length correction in total hip arthroplasty

PURPOSE

Residual feeling of leg length discrepancy (LLD) is a common cause of patient dissatisfaction following total hip arthroplasty (THA). The purpose of this study is to propose a method for determining an optimal leg length correction goal in THA.

METHODS

We conducted a retrospective study of 132 patients to examine the radiographic LLD (R-LLD), perceived LLD (P-LLD), and whether or not the patient has an uncomfortable feeling about the leg length after THA.

RESULTS

The residual discomfort rate in all patients was 9.1% (12/132 patients), and ten of these 12 patients felt uncomfortable due to a longer leg length. When R-LLD was within 7 mm, the rate was 6.8% (8/118 patients), which is nearly equal to the rate of 7.8% (5/64 patients) in cases in which R-LLD was within 2 mm. On the other hand, when R-LLD was 8 mm or more, the rate was 57.1% (4/7 patients).

CONCLUSIONS

The results of our study show that 7 mm may be a reasonable threshold for reducing the residual discomfort. However, even with little or no R-LLD, some patients will continue to experience discomfort. We think that this is because of pre-operative differences between R-LLD and P-LLD in such cases. If the patient has a pelvic declination on the affected hip side and a lumbar scoliosis angle that is convex toward the affected hip side before surgery, the ideal length may be a little shorter than the radiographic isometry, since such patients are likely to feel a longer leg length than that shown radiographically.

Rapidly destructive arthropathy of shoulder joint

BACKGROUND

Rapidly destructive arthropathy (RDA) of the shoulder is rare. Consequently, there are very few studies that have reported the characteristic findings of this disease. This study aimed to analyze the clinical, radiographic, and histologic features of patients with RDA of the shoulder.

METHODS

In total, 9 cases (8 patients) were enrolled in this study. All patients were elderly women, with a mean age of 72.7 years (range, 57-78 years). The mean duration of symptoms was 4.1 months (range, 1.2-5.9 months). Reverse total shoulder arthroplasty and total shoulder arthroplasty were performed in 5 cases with massive rotator cuff tears and 4 without them, respectively.

RESULTS

The mean duration of radiologically evident joint destruction after negative results on radiography was 3.1 months (range, 1.0-5.9 months). On plain radiography, humeral head flattening and collapse that appeared like cut grass were observed (100%). Relatively good preservation of the glenoid with a normal joint space was observed in 7 cases, whereas glenoid erosion was observed in 2 (22.2%). T1-weighted magnetic resonance imaging showed a subchondral fracture (100%) of low signal intensity with associated bone marrow edema. Histologically, chronic inflammation of the synovium and osteocytes in the lacunae, as well as callus formation, were observed along the subchondral fracture.

CONCLUSION

Flattening and collapse of the humeral head within an average of 4 months of symptom onset are characteristic of RDA of the shoulder. Bone marrow edema, joint effusion, and subchondral fracture on magnetic resonance imaging and fracture fragments and callus formation on histopathologic analysis were observed. Glenoid erosion was observed in 2 cases with arthrosis progression.

Inflammatory joint diseases and atherosclerosis: time to look beyond the 'lipid paradox'

PURPOSE OF REVIEW

Uncertainty persists about the contribution of lipids to the increased risk of cardiovascular disease (CVD) among rheumatoid arthritis and other inflammatory joint disease (IJD) patients. In reviewing recent research, we consider potential insights gained by quantifying lipoprotein particles directly, rather than by their lipid content.

RECENT FINDINGS

Although inflammation often decreases LDL cholesterol (LDL-C), and anti-inflammatory medications often increase LDL-C, both inflammation and anti-inflammatory medications can increase atherogenic Apolipoprotein B (ApoB)-containing lipoprotein particles, attenuated by statins. CVD risk factors, that is, smoking, obesity, ApoB, may increase years prior to IJD diagnosis. Increased risks of nonatherosclerotic myocardial and pulmonary disease, heart failure and mortality may be directly related to disease activity, inflammation, and possibly to HDL particles and function.

SUMMARY

For IJD patients, higher cumulative lifetime exposure to CVD risk factors accelerates atherosclerosis and subsequent CVD risk that is underestimated by current risk factor levels. CVD risk reduction in IJD requires aggressive and earlier reduction in CVD risk factors (ApoB lipoproteins, smoking, hypertension, diabetes, lack of physical activity), in addition to control of disease activity and inflammation. Lipid-lowering medications can attenuate anti-inflammatory medication-induced increases in ApoB and LDL-C, but can also reduce CVD risk due to cumulative lifetime exposure.

Development and Reliability of the Joint Tissue Activity and Damage Examination for Quantitation of Structural Abnormalities by Musculoskeletal Ultrasound in Hemophilic Joints

OBJECTIVES

Musculoskeletal ultrasound (US) is used increasingly to examine hemophilic arthropathy. However, quantitative algorithms to document findings are lacking. We developed and sought to validate a protocol quantifying hemophilic joint abnormalities.

METHODS

Thirty-one patients with hemophilia were examined serially for 2 years with musculoskeletal US (≈600 joint examinations and ≈6000 images). Based on the spectrum of pathologies, a quantitative algorithm, named Joint Tissue Activity and Damage Examination (JADE), was developed for soft tissue and osteochondral measurements, including power Doppler, using nominal group techniques. To study intra- and inter-rater reliability, 8 musculoskeletal US-experienced hemophilia providers performed anatomic landmark recognition and tissue measurements on 86 images with arthropathic changes, with repetition 1 month later. Twenty-three musculoskeletal US-inexperienced providers performed similar assessments. Inter-operator reliability was established by 6 musculoskeletal US-experienced hemophilia providers, each acquiring images and JADE assessments of 3 hemophilic arthropathic joints. A radiologist and musculoskeletal sonographer functioned as adjudicators. The statistical analysis was performed with the intraclass correlation coefficient (ICC), Fleiss κ, and Cohen κ where appropriate.

RESULTS

The musculoskeletal US-experienced providers showed excellent intra-and inter-rater reliability for tissue measurements (ICCs, 0.94-0.96). Agreement was good to excellent for landmark recognition (Fleiss κ, 0.87-0.94). Inter-operator reliability was excellent for measurements and landmark recognition (ICC, 0.90; Fleiss κ, 1.0). Agreement with adjudicators was mostly good to excellent. Musculoskeletal US-inexperienced providers showed excellent inter-rater reliability for measurements (ICC, 0.96) and moderate agreement for landmark recognition (Fleiss κ, 0.58).

CONCLUSIONS

The JADE protocol appears feasible for quantifying hemophilic intra-articular abnormalities. Musculoskeletal US-trained hemophilia providers showed high intra-rater, inter-rater, and inter-operator reliability, supporting JADE as a protocol for clinical management and research.

Tranexamic Acid Reduces Transfusion Rates in Obese Patients Undergoing Total Joint Arthroplasty

BACKGROUND

While tranexamic acid (TXA) has been well shown to reduce blood loss after joint replacement surgery, little is known regarding its effectiveness in obese patients. The aim of this study was to evaluate the effect of TXA changes in hematocrit and hemoglobin levels as well as incidence of packed red blood cell (pRBC) transfusions in obese patients undergoing total joint arthroplasty (TJA).

MATERIAL AND METHODS

Between January 2014 and May 2015, 420 consecutive primary joint replacements were performed by two surgeons at our institution. One-hundred-fifty-seven patients (total hip arthroplasty [THA]=29; total knee arthroplasty [TKA]=128) were obese with a body mass index (BMI) greater than or equal to 30 kg/m2. Medical records were reviewed and identified that TXA was utilized in 85 (54.1%) arthroplasties (study group) and was compared to a consecutive series of 72 (45.9%) TJAs (control group). TXA was given intravenously (IV) in two doses: (1) one gram prior to incision and (2) one gram at the time of femoral preparation in THA or prior to cementation in TKA. Changes in hemoglobin and hematocrit levels, number of pRBC transfusions, and occurrence of thrombolytic events were recorded.

RESULTS

The changes in hematocrit (7.2% vs. 8.1%) and hemoglobin levels (3.0 g/dl vs. 3.3 g/dl) were less in the group that received TXA than the control group, albeit not significantly (p=0.100 and p=0.278, respectively). Within the control group, 26 (36.1%) patients required a pRBC transfusion with a mean of 2.0 units per patient (range:1-5); whereas, only eight (9.4%) patients with TXA required a mean of 1.6 units per patient (range: 1-2). The use of TXA significantly reduced the incidence of pRBC transfusions, especially in TKA (p<0.001). Sub-analyses revealed that transfusion rates were even more significantly reduced by TXA in obesity type II and III. Two pulmonary emboli were reported in the group that did not receive TXA; whereas, no thrombolytic events were reported in the group that did receive TXA.

CONCLUSION

Utilization of TXA significantly reduced the rate of pRBC transfusions in obese patients.

Clinical and diagnostic outcomes in arthroscopic treatment for posterolateral plicae impingement within the radiocapitellar joint

Synovial plica is rarely diagnosed as cause of elbow pain. Impingemnt of posterolateral plicae in the radiocapitellar joint tends to be usually overlooked. The purpose of this study was to present outcomes of arthroscopic treatment in relatively large number of cases and propose reliable diagnostic test for posterolateral plicae of the radiocapitellar joint.From January 2000 to December 2010, 24 cases diagnosed with pathologic posterolateral radiocapitellar plica on arthroscopic finding were retrospectively reviewed. Magnetic resonance imaging (MRI) evaluation and preoperative physical examination were performed. The posterolateral radiocapitellar plica test newly proposed by the present study was also conducted. To measure postoperative clinical outcomes, the disabilities of the arm, shoulder, and hand (DASH) score and Mayo elbow performance score (MEPS) were employed. Minimum duration of follow up was 24 months.According to the preoperative MRI, pathologic radiocapitellar plica was identified in 17 cases (70.8%). Preoperatively, maximal tender point was present on the radiocapitellar joint line in 20 cases (83.3%) and mechanical symptoms were observed in 9 cases (37.5%). 6 cases (25%) demonstrated pain at terminal extension and limitation of extension. 20 (83.3%) cases tested positive for posterolateral radiocapitellar plica test. The sensitivity and specificity of the posterolateral radiocapitellar plica test were 83.3% and 87.5%, respectively. The accuracy value was 86.3%. Arthroscopic debridement of pathologic plica in the radiocapitellar joint demonstrated clinical improvements: DASH score was from 36.6 to 8.9 and MEPS was from 56.9 to 95.6 at the latest follow-up.Symptomatic impingement by the pathologic posterolateral plica of the radiocapitellar joint should be considered when posterolateral elbow pain which is refractory to conservative treatment, and other prevalent diseases are excluded. The posterolateral radiocapitellar plica test and radiocapitellar joint line tenderness could be recommended as reliable examination maneuvers to obtain accurate diagnosis. Arthroscopic debridement was an effective method for treating symptomatic plicae.

[Bruxism, myoarthropathy and psychosomatics]

Bruxism and myoarthrophathy lead to a complex set of burdens that can involve both medical and psychological aspects. Muscular tension due to stress affects these burdens and leads to chronic pain. Using a stress model, it was explained how the individual processing of stress leads to varying negative effects on oral health and jaw function. Through a short survey, it is possible for the dentist to assess the extent of the chronic pain and the associated psychosocial burdens, and, when necessary, encourage the patient to undertake psychological guidance. By learning relaxation techniques and pain coping mechanisms, the pain can be reduced. In order to achieve a long lasting successful treatment, one must consider both medical and psychosomatic aspects.

Diagnostic nerve blocks in the management of low back pain secondary to facet joint syndrome

Low back pain is currently one of the main public health problems. Among the multiple causes, pain in the zygapophysial joints, also called facets or posterior vertebral joints, are an important cause, usually secondary to osteoarthritis. The source of low back pain is often difficult to find, making the therapeutic approach to the patient sub-optimal. Diagnostic blocks are a very important tool in establishing an adequate treatment for patients with low back pain, as long as they are performed accurately, with an adequate local anaesthetic volume, with a suitable image and fluoroscopic projection and its result are precisely interpreted. In this article a review is presented on the importance of diagnostic blocks, as well as how they should be performed in order to obtain the maximum information and the greatest therapeutic benefit.

Association between adolescent idiopathic scoliosis and sacroiliac joint dysfunction in young athletes: A case control study

Adolescent idiopathic scoliosis (AIS) is the most common form of scoliosis, a 3-dimensional deviation in the axis of the spine. Etiology of AIS is unclear and the general belief is that AIS is multifactorial disorder possibly caused by different factors. It would be worthwhile to reveal new factors associated with AIS. The present study aimed to investigate association between sacroiliac joint (SIJ) dysfunction and AIS in young athletes.This case-control study included 196 children athletes (basketball, football, volleyball, handball, ballet, and others), 82 males and 114 females aged 8 to 17, 98 of them with the diagnosis of AIS. The case group consisted of young athletes examined at a regular checkup by a sport physician and diagnosed with AIS. The control group consisted of athletes matched to the case group according to sex, age, sports, number of training years and number of training hours per week, but without AIS.The scoliosis was diagnosed with Adams' forward bend test and the scoliometer measurement. The SIJ dysfunction was determined using the palpation meter (PALM) measuring the sagittal pelvic position in standing position and in standing position with the hip flexion angle of 90°. The data were analyzed using Student t test, Mann-Whitney U test, contingency coefficients, and logistic regression.The average difference in pelvic position in the sagittal plane (in standing position), with and without hip flexion 90° was found to be statistically different in the case and the control groups (t = 13.88, P = .00). There was a strong positive association between variables representing presence of AIS and SIJ dysfunction (determined by contingency coefficient C = 0.62, coefficient Phi = 0.79 and tetrachoric correlation coefficient 0.95).The logistic regression indicated that the average difference in pelvic position in the sagittal plane (in standing position), with and without hip flexion 90° was significantly associated with the probability of scoliosis in young athletes (P = .00, Wald test).There was a strong positive association between SIJ dysfunction and AIS in young athletes.

Frostbite arthropathy - a rare case of osteoarthritis, review of the literature and case presentation

Frostbite affects more commonly the northern population then it was suspected earlier, but wherever cold winter occurs, cold caused lesions are reported. Most often, it is described as soft tissue lesions, but deeper structures like tendons, ligaments, muscles, cartilage or bones can be affected. All extremities can be involved; lesions can lead to necrosis and amputations. First documented cases were described during military actions, but occupational or recreational activities can also be a risk factor for frostbite. Frozen or frostbite arthropathy is a rare cause of osteoarthritis. Usually, arthritis appears after a long time after frostbite, it can be decades apart. Frostbite arthropathy can result in different debilitating conditions. The current review describes the most important changes in frostbite and a rare but very serious late complication, which lead to arthropathy.

Evaluation of early musculoskeletal disease in patients with haemophilia: results from an expert consensus

: Early joint damage in patients with haemarthrosis often escapes diagnosis because of insufficient investigation of biomechanical changes. Arthropathy in haemophilia requires complex assessment with several tools. Considering the increased emphasis on an integrated approach to musculoskeletal (MSK) outcomes, re-evaluation of MSK assessment to address individual patient needs is warranted. To advise on the optimal use of current assessment tools and strategies for tailored MSK evaluation in patients with haemophilia. A panel of experts in haemophilic arthropathy evaluated internationally recognized assessment tools through published literature and personal expertise. Each tool was considered, scored and ranked for their utility in the clinical assessment of MSK damage. Subsequently, a patient evaluation table detailing advice on type and frequency of assessments for different patient populations was constructed. To obtain a complete MSK assessment, multiple tools must be used to ensure each criterion is evaluated. For patients with haemophilia, clinical examination of the joint, disease-specific structure/function scores, and activity/participation scores including quality of life are important, and should be performed on a regular basis according to age and clinical condition. Joint imaging is recommended in the prevention, diagnosis and follow-up of haemophilic arthropathy and should be used in conjunction with joint structure and function scores. An integrated approach to MSK assessment using combinations of tools will allow earlier management of dysfunction and may improve long-term outcomes. This approach could be used in long-term follow-up of all patients independent of age and disease stage, especially in children to prevent arthropathy.

Postpartum sacral stress fracture associated with mechanical sacroiliac joint disease: A case report

RATIONALE

Stress fractures of the sacrum and mechanical sacroiliac joint disease can occur not only during pregnancy but also postpartum. Mechanical sacroiliac joint disease is common in patients with low back pain but often misdiagnosed by practitioners. The association of the 2 conditions has not been studied yet.

PATIENT CONCERNS

A 37-year-old woman physiatrist presented with 8-week history of persistent low back and left buttock pain that started in the third trimester of her pregnancy.

DIAGNOSES

Laboratory investigation, dual-energy x-ray absorptiometry, magnetic resonance imaging, and CT of the pelvic region were performed. The patient was diagnosed with postpartum sacral stress fracture associated with mechanical sacroiliac joint disease.

INTERVENTIONS

Treatment consisted in pain killers and tailored to a nonweight-bearing period of 3 months.

OUTCOMES

Painful symptoms disappeared and the patient was able to walk and perform other daily activities normally.

LESSONS

Clinician should be aware of the clinical context and the possible association of these 2 conditions in order to undertake an early and appropriate treatment.

Advanced Hemophilic Arthropathy: Sensitivity of Soft Tissue Discrimination With Musculoskeletal Ultrasound

OBJECTIVES

Point-of-care musculoskeletal ultrasound (US) is increasingly used by hemophilia providers to guide management; however, pathologic tissue differentiation with US is uncertain. We sought to determine the extent to which point-of-care musculoskeletal US can identify and discriminate pathologic soft tissue changes in hemophilic arthropathy.

METHODS

Thirty-six adult patients with hemophilia A/B were prospectively enrolled. Point-of-care musculoskeletal US examinations were performed on arthropathic joints (16 knees, 10 ankles, and 10 elbows) using standard views by a musculoskeletal US-trained and certified hematologist, who recorded abnormal intra-articular soft tissue accumulation. Within 3 days, magnetic resonance imaging was performed using conventional and multiecho ultrashort echo time sequences. Soft tissue identification (synovial proliferation with or without hemosiderin, fat, and/or blood products) was performed by a musculoskeletal radiologist. Findings obtained with both imaging modalities were compared and correlated in a blinded fashion.

RESULTS

There was perfect agreement between the modalities on the presence of abnormal soft tissue (34 of 36 cases). However, musculoskeletal US was unable to discriminate between coagulated blood, synovium, intrasynovial or extrasynovial fat tissue, or hemosiderin deposits because of wide variations in echogenicity.

CONCLUSIONS

Musculoskeletal US is valuable for point-of-care imaging to determine the presence of soft tissue accumulation in discrete areas. However, because of limitations of musculoskeletal US in discriminating the nature of pathologic soft tissues and detecting hemosiderin, magnetic resonance imaging will be required if such discrimination is clinically important.

The Influence of Obesity on Total Elbow Arthroplasty

Total elbow arthroplasty (TEA) has undergone a significant evolution in indications and outcomes in the past decade. Although rheumatoid patients once had the overwhelming number of TEAs, now TEAs for the sequelae of trauma predominate. Furthermore, as obesity has mirrored the increase in the posttraumatic population, TEA complications have increased whereas the durability of implants under these loads has decreased. Solutions are urgently needed to address the complications and revision burden related to posttraumatic deformity and obesity.

Functional Outcomes and Predictors of Failure After Rotator Cuff Repair During Total Shoulder Arthroplasty

A well-functioning rotator cuff is necessary for successful anatomic total shoulder arthroplasty (TSA). This study evaluated patients who underwent concomitant TSA and rotator cuff repair (RCR) for functional outcomes, revision rates, and predictors of poor results. Retrospective chart review was conducted to identify patients who underwent TSA and RCR. Demographic data, rotator cuff tear and RCR characteristics, range of motion, and radiographs were recorded. Minimum 2-year functional outcomes were obtained. Predictors of reoperation and/or poor clinical results were determined. Forty-five patients met inclusion criteria (22 high-grade partial-thickness and 23 full-thickness tears). Fourteen (31%) patients were labeled as having a poor result; 8 (18%) patients required reoperation. There was a significant difference between the acromiohumeral interval preoperatively and immediately postoperatively (P=.013). However, at maximum radiographic follow-up, the acromiohumeral interval was not significantly different from preoperative values (P=.86). Patients with a preoperative acromiohumeral interval of less than 8 mm had an increased rate of cuff-related reoperation (P=.003). Although concomitant TSA and RCR is a reasonable consideration, 31% of patients had a poor clinical result. An acromiohumeral interval of less than 8 mm was a predictor of cuff-related reoperation and may be an indication to consider reverse arthroplasty in the setting of joint arthrosis with a rotator cuff tear.

Insulin-Dependent Diabetes Is an Independent Risk Factor for Complications and Readmissions After Total Joint Replacements

This study examined the risk for postoperative complications, reoperations, and readmissions for patients with insulin-dependent diabetes mellitus (IDDM), patients with non-insulin-dependent diabetes mellitus (NIDDM), and patients without diabetes undergoing total joint replacements (TJRs). The American College of Surgeons National Surgical Quality Improvement Program database was queried for all primary TJRs in 2015. The study identified 78,744 TJRs (84.1% nondiabetic patients, 12.0% NIDDM, and 3.9% IDDM). Multiple logistic regression models identified IDDM as an independent risk factor for increased blood loss, myocardial infarctions, pneumonia, renal insufficiency, urinary tract infections, and readmissions when compared with both NIDDM and nondiabetics. Risk for wound complications and reoperations were comparable between all three groups. IDDM increases the risk for medical complications and readmissions after TJRs. Physicians must counsel patients on the increased risks associated with IDDM before elective surgery and provide appropriate medical support for these patients.

Arthroscopic Excision of Tendinous Giant Cell Tumors Causing Locking in the Knee Joint

PURPOSE OF THE STUDY Non-osseous giant cell tumors are locally aggressive tumors arising around joints. They are commonly located around synovial joints such as wrist and knee and occasionally cause mechanical symptoms. MATERIAL AND METHODS This retrospective case series includes 7 patients operated due to intraarticular lesion. The mean age of the patients was 28.7 (range 22-37) years. Mean follow-up period was 12 months. RESULTS All patients underwent arthroscopic debridement. They were followed monthly with clinical examination and magnetic resonance imaging (MRI) was obtained at third month for all patients. Patients were contacted through phone call and evaluated with the WOMAC score retrospectively. No recurrence was detected in any patient. CONCLUSIONS Arthroscopic debridement is a safe surgical technique that may replace open surgery in the treatment of intraarticular tendinous giant cell tumors. Key words:tendinous giant cell tumor, arthroscopy, knee locking.

Systemic Lupus Erythematosus is a Risk Factor for Complications in Total Joint Arthroplasty

Introduction

Systemic Lupus Erythematosus (SLE) has been associated with increased complications following hip and knee arthroplasty. The Purpose of this study was to determine the extent to which SLE is a risk factor in outcomes following total joint arthroplasty (TJA).

Methods

The nationwide inpatient sample was used to identify a cohort of 505,841 patients who had a total hip arthroplasty (THA) or total knee arthroplasty (TKA) between 2009-2011. Of these patients, 2,284 patients (0.45%) had been previously diagnosed with SLE. The impact of SLE on short-term TJA outcomes was determined using multivariate logistic regression. Differences in discharge destination and length of stay were also evaluated.

Results

SLE patients were more likely to have an all-cause medical complication, (OR 1.9, p<0.0001) and more likely to have an all-cause surgical complication (OR 1.3, p<0.0001). SLE patients were four times more likely to become septic in the post-operative period (OR 3.8, p<0.0487). SLE patients were more likely to have a genitourinary complication (OR 1.7, p<0.0001) and bleeding complications requiring transfusion (OR 2.1, p<0.0001). Patients with SLE also had an increased length of stay (0.38 days, p<0.0001) and increased probability of discharging to a facility (OR 2.1, p<0.0001).

Discussion

Patients with SLE had an increased rate of both medical and surgical all-cause complications. Patients were specifically found to be at higher risk for sepsis, genitourinary complications, and blood transfusions. Future risk adjustment models should include SLE as a contributor to medical and surgical complications in the postoperative period.

Body mass index as a predictor of outcome in total knee replace: A systemic review and meta-analysis

BACKGROUND

To conduct a meta-analysis with randomized controlled trials (RCTs) published in full text to demonstrate database to show the associations of perioperative, postoperative outcomes of normal and high body mass index (BMI) to provide the predictive diagnosis for clinic.

METHODS

Literature search was performed in PubMed, Embase, Web of Science and Cochrane Library for information from the earliest date of data collection to February. RCTs comparing the benefits and risks of normal BMI with those of high BMI in primary total knee arthroplasty (TKA) were included. Statistical heterogeneity was quantitatively evaluated by X2 test with the significance set P<0.10 or I2>50%.

RESULTS

Seven RCTs consisting of 33,778 patients were included. (6065 normal BMI patient; 27,713 high BMI). The results showed that high BMI was related to a greater increase in operative time, post-operative range of motion (ROM), post-operative Knee Society and function scores (KSS), infection rate (P<0.1). No differences in pulmonary embolism and perioperative mortality rates were found between normal and high body mass index patients with follow-up≥5years (P>0.1).

CONCLUSIONS

Compared with normal BMI patients, high BMI patients demonstrated an increased risk of perioperative and postoperative complications and clear difference about complications between normal and high BMI about TKA.
