Genetic Polymorphisms in COL1A2 gene and the Risk of Tendinopathy: Case-Control Study / Polimorfismos genéticos no gene COL1A2 eo risco de tendinopatia: Estudo de caso-controle

Abstract Objective To evaluate the influence of polymorphisms on genes encoding type I collagen and the genetic susceptibility of tendinopathy. Methodology Case-control study involving 242 Brazilian athletes from different sports modalities (55 cases of tendinopathy and 187 controls). The polymorphisms COLIAI (rs1107946) and COLIA2 (rs412777, rs42524, and rs2621215) were analyzed by theTaqMansystem. Odds ratio(OR)withtheir 95% confidence intervals (CIs) were calculated using a nonconditional logistic regression model. Results The mean age was 24.0 ± 5.6 years old and 65.3% were men. Of the 55 cases of tendinopathy, 25.4% had > 1 affected tendon, the most frequent being patellar (56.3%), rotator cuff (30.9%) and elbow or hand flexors (30.9%). Age and amount of time of sports practice were associated with a higher chance of presenting tendinopathy (5 and 8 times, respectively). The frequency of variant alleles in control and case patients, respectively, was: COLIAI rs1107946 24.0 and 29.6%; COLIA2 rs412777 36.1 and 27.8%; rs42524 17.5 and 25.9%; and rs2621215 21.3 and 27.8%. After adjusting for confounding factors (age and years of sports practice), COLIA2 rs42524and rs2621215 polymorphisms were associated with increased risk of tendinopathy (OR = 5.5; 95% CI = 1.2-24.6 and OR = 3.9; IC95% = 1.1-13.5, respectively). The haplotype COLIA2 CGT was associated with low risk for disease development (OR = 0.5; 95%CI = 0.3-0.9). Conclusion Age (≥ 25 years old), time of sports practice (≥ 6years) and polymorphisms in the COLIA2 gene increased the risk of developing tendinopathy.

There was no significant difference in VAS and VISA-A score between two groups before treatment, 1 and 3 months after treatment(P>0.05), while VAS and VISA-A score in PRP group were better than those in shock wave group at 6 months after treatment(P<0.05), and the satisfaction survey in PRP group was better than that in shock wave group(P<0.05).@*CONCLUSION@#PRP injection has a good clinical effect on chronic insertional Achilles tendinopathy with high patient satisfaction, and medium-and long-term effect of PRP injection for the treatment of chronic insertional Achilles tendinopathy is better than that of extracorporeal divergent shock wave.

Total rupture of Achilles tendon induces inflammatory response and glial activation on the spinal cord of mice

Rupture of Achilles tendon is a common accident affecting professional and recreational athletes. Acute and chronic pain are symptoms commonly observed in patients with rupture. However, few studies have investigated whether Achilles tendon rupture is able to promote disorders in the central nervous system (CNS). Therefore, the current study aimed to evaluate nociceptive alterations and inflammatory response in the L5 lumbar segment of Balb/c mice spinal cord after Achilles tendon rupture. We found increased algesia in the paw of the ruptured group on the 7th and 14th days post-tenotomy compared with the control group. This phenomenon was accompanied by overexpression of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase-2 (NOS-2) as well as hyperactivation of astrocytes and microglia in nociceptive areas of L5 spinal cord as evidenced by intense GFAP and IBA-1 immunostaining, respectively. Biochemical studies also demonstrated increased levels of nitrite in the L5 spinal cord of tenotomized animals compared with the control group. Thus, we have demonstrated for the first time that total rupture of the Achilles tendon induced inflammatory response and nitrergic and glial activation in the CNS in the L5 spinal cord region.

Flexor Hallucis Longus Transfer And V-Y Plasty: An Effective Treatment Modality for Chronic Achilles Rupture - A Case Series

@#Introduction: To assess outcomes of FHL transfer and V-Y plasty for chronic Achilles rupture due to insertional Achilles tendinopathy. Materials and methods: A case series of 12 patients was conducted between 1st January 2017 and 31st December 2018. The patients had short flexor hallucis longus tendon transfer with gastrocnemius lengthening by V-Y plasty for Achilles tendon rupture. Patients were allowed full weight bearing at six weeks post-operatively, and were followed up at three months and six months post-operatively, when the range of motion of the ankle was examined, and the outcome was assessed using the EFAS score. Results: Of the 12 patients in the study, the majority were males; the mean age was 50.6±8.96 years. A significant improvement in dorsiflexion and plantarflexion was noted at the six-month follow-up compared to the three-month follow-up (P=<0.001 for both). When compared to the normal side, dorsiflexion and plantarflexion of the affected ankle were significantly less at three months but were comparable at six months post-operatively. A significant improvement was noted in the mean EFAS score at the sixmonth follow-up (25.5±5.71) compared to three months (18.6±0.90) post-surgery (P=0.001). Males were also noted to have significantly higher EFAS scores at their six-month follow-up than females (P=0.022). In contrast, a negative correlation was noted between the European Foot and Ankle Society (EFAS) score at the final follow-up and age (P=0.011). Conclusion: FHL tendon transfer with V-Y plasty in chronic Achilles rupture due to insertional Achilles tendinopathy is an effective procedure resulting in the restoration of the ankle range of motion and improvement in functional scores.

Feasibility of MRI assisting early diagnosis of midfoot ligament and tendon injuries / 中华全科医师杂志

Objective:To explore the feasibility of MRI to assist the early diagnosis of midfoot tendon and ligament injuries.Methods:Fifty-two patients with midfoot ligament and tendon injuries who visited Beijing Jishuitan Hospital from September 2016 to December 2021 were enrolled in the study, and 20 healthy volunteers were recruited as controls. All participants underwent mid foot coronal (short axis), sagittal, and axial (long axis) MRI T1 weighted imaging and proton fat suppression sequence examination. The MRI images were evaluated by 2 senior radiologists independently.Results:The consistency of the two radiologists in diagnosis of tendons, ligaments, bones, and soft tissues were good ( κ=0.916, 0.896, and 0.893, respectively). The tendons and ligaments of the midfoot in 20 healthy volunteers (40 feet) showed uniform bands of varying thickness with slightly low signal intensity; the anterior tibial tendon showed a thin line shape, the posterior tibial tendon showed a slightly thick band with uniform low signal intensity, and the calcaneonavicular ligament showed a thin line-like low signal intensity running in different directions. In 52 patients with midfoot tendon and ligament injuries, 18 had anterior tibial tendon injuries, 20 had posterior tibial tendon injuries, and 14 had calcaneonavicular ligament injuries. The injured tendon or ligament was characterized by uneven thickness, blurred edges, and continuous interruption on T1WI sequence, uneven enhancement of signal in the tendon or ligament running area on PD-FS sequence, accumulation of fluid in the tendon sheath, and partial tearing. The partial tear showed discontinuity and thickening of tendons, while the complete tear showed that the tendons were interrupted and retracted, the fiber structure disappeared and was filled with liquid, and the surrounding soft tissue edema was present. Conclusion:MRI can clearly display the course and anatomical structure of the attachment end of the midfoot tendon and ligament, which may assist in early diagnosis of midfoot tendon and ligament injuries.

Arthroscopic modified Brostr?m procedure combined with peroneal tendon debridement in the treatment of chronic lateral ankle instability concomitant with fibular tendinitis / 中华创伤杂志

Objective:To compare the efficacies of arthroscopic modified Brostr?m procedure combined with or without peroneal tendon debridement in the treatment of chronic lateral ankle instability (CLAI) concomitant with fibular tendinitis.Methods:A retrospective cohort analysis was conducted on the clinical data of 31 patients with CLAI concomitant with fibular tendinitis, who were treated in Beijing Tongren Hospital, Capital Medical University between March 2019 and December 2021. The patients included 17 males and 14 females, aged 16-57 years [(32.8±9.6)years]. The anterior drawer test and talar tilt test were positive in all patients preoperatively. Diagnosis was confirmed by physical examination and MRI, and calcaneofibular ligament rupture was excluded. Eleven patients received arthroscopic modified Brostr?m procedure combined with peroneal tendon debridement (modified Brostr?m procedure+tendon debridement group), and 20 underwent pure arthroscopic modified Brostr?m procedure (modified Brostr?m procedure group). The operation time, intraoperative blood loss and length of hospital stay were documented. The visual analogue score (VAS) in peroneal tendon area was assessed before operation and at postoperative 2, 6 and 12 weeks. The American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and foot and ankle outcome score (FAOS) were assessed before operation and at postoperative 6 and 12 weeks. The anterior drawer test was performed at the last follow-up. The foot and ankle ability measure (FAAM) score was assessed before operation and at the last follow-up. Postoperative wound healing and complications were also observed.Results:All the patients were followed up for 4-19 months [(11.3±3.5)months]. The operation time was (66.0±4.2)minutes in the modified Brostr?m procedure+tendon debridement group, which was significantly longer than (61.5±3.4)minutes in the modified Brostr?m procedure group ( P<0.05). There was no significant difference in intraoperative blood loss or length of hospital stay between the two groups (all P>0.05). Compared with the preoperation, the value of VAS was significantly lowered, and the values of AOFAS ankle-hindfoot score, FAOS and FAAM score were significantly increased at different postoperative timepoints (all P<0.01). No significant differences in the values of VAS, AOFAS ankle-hindfoot score, FAOS or FAAM score were seen between the two groups before operation (all P>0.05). The value of VAS was 3.0(3.0, 4.0) points in the modified Brostr?m procedure+tendon debridement group, being markedly different from 4.0(4.0, 4.0)points in the modified Brostr?m procedure group at 2 weeks postoperatively ( P<0.05). The value of VAS was 2.0(1.0, 3.0)points in the modified Brostr?m procedure+tendon debridement group, being markedly different from 3.0(2.3, 3.0)points in the modified Brostr?m procedure group at 6 weeks postoperatively ( P<0.05). At 12 weeks postoperatively, there was no significant difference in the value of VAS between the two groups ( P>0.05). There were no significant differences in the values of AOFAS ankle-hindfoot score and FAOS between the two groups at 6 or 12 weeks postoperatively (all P>0.05). The anterior drawer test was negative in all patients at the last follow-up. No significant difference was seen in the value of FAAM score between the two groups at the last follow-up ( P>0.05). All incisions were healed well in the first stage after operation, without the occurrence of joint infection, impaired joint motion, nerve injury or deep vein thrombosis. Conclusions:Arthroscopic modified Brostr?m procedure combined with or without peroneal tendon debridement can both improve the foot function in CLAI patients concomitant with fibular tendinitis. However, the combined treatment allows for early pain relief, without increasing the risk of complications, and can therefore contribute to a faster postoperative recovery.

Introducción: Los antiinflamatorios no esteroideos son comúnmente usados para el tratamiento de las tendinopatías, pero la evidencia sobre este tratamiento es escasa. Objetivo: Realizar una revisión sistemática acerca de los efectos de los en las tendinopatías. Métodos: Se desarrolló una búsqueda bibliográfica en PubMed, WOS, PEDro, Medline, Cinahl y SPORTDiscus. Se incluyeron un total de 13 ensayos clínicos con una calidad metodológica media de 7,15/10 en la escala PEDro. Conclusiones: En la mayoría de los artículos se observó una mejoría corto plazo en el dolor y la funcionalidad con el uso de AINEs. Los ensayos clínicos incluidos no analizaron la presencia de inflamación en esta patología. Se necesitan más estudios que determinen la función de la inflamación en la tendinopatía que justifique el uso de los antiinflamatorios no esteroideos(AU)

Introduction: Non-steroidal anti-inflammatory drugs are commonly used for the treatment of tendinopathies, but the evidence on this treatment is scarce. Objective: To carry out a systematic review about the effects of non-steroidal anti-inflammatory drugs in tendinopathies. Methods: A bibliographic search was carried out in PubMed, WOS, PEDro, Medline, Cinahl and SPORTDiscus. A total of 13 clinical trials with a mean methodological quality of 7.15/10 on the PEDro scale were included. Conclusions: In most of the articles, a short-term improvement in pain and functionality was observed with the use of non-steroidal anti-inflammatory drugs. The clinical trials included did not analyze the presence of inflammation in this pathology. More studies are needed to determine the role of inflammation in tendinopathy that justifies the use of nonsteroidal anti-inflammatory drugs(AU)

Acute longus colli tendinitis and otolaryngology / Tendinite aguda do músculo longus colli e otorrinolaringologia

Abstract Introduction Acute longus colli tendinitis is caused by calcium hydroxyapatite deposition in the tendon of the longus colli muscle with subsequent inflammation. The calcifications are commonly located at the superior oblique portion at the level of the C1-C2 vertebrae. The typical clinical presentation consists of acute neck pain, odynophagia, and painful limitation of neck range of motion. Objectives We will describe this disease with three that cases presented to our institution and compare the findings on imaging studies. Methods We retrospectively reviewed the clinical data, radiological features, and laboratory reports of three patients diagnosed with acute longus colli tendinitis. Computed tomography and plain radiographs were reviewed and compared by a single radiologist. A contemporary review of the literature was conducted using PubMed (Medline), Embase, and Cochrane library databases. Results Computed tomography showed greater sensitivity for the detection of the pathognomonic calcification than plain radiographs and facilitated the exclusion of other more severe conditions by following a systematic interpretation composed of five key elements. Plain radiographs showed non-specific signs of prevertebral soft tissue swelling and a decreased cervical lordotic curve. However, no calcification was identified on plain radiographs. The literature review revealed 153 articles containing 372 cases. Surgical or invasive procedures were mentioned in 13.7% of publications and were performed in 28 patients. Conclusion Acute longus colli tendinitis can mimic the clinical presentation of more severe conditions that the otolaryngologist may be required to evaluate, such as infectious, traumatic, and neoplastic diseases. Knowledge of this entity, with its pathognomonic imaging findings, can prevent misdirected medical therapy and unnecessary invasive procedures.

Resumo Introdução A tendinite aguda do músculo longus colli é causada pela deposição de hidroxiapatita de cálcio no tendão do músculo longus colli com subsequente inflamação. As calcificações estão comumente localizadas na porção oblíqua superior ao nível das vértebras C1-C2. A apresentação clínica típica consiste em dor cervical aguda, odinofagia e limitação dolorosa da amplitude de movimento do pescoço. Objetivos Descreveremos essa doença por meio de três casos apresentados em nossa instituição e compararemos os achados em exames de imagem. Método Revisamos retrospectivamente os dados clínicos, as características radiológicas e os relatórios laboratoriais de três pacientes com diagnóstico de tendinite aguda do músculo longus colli. A tomografia computadorizada e as radiografias simples foram revisadas e comparadas por um único radiologista. Uma revisão contemporânea da literatura foi feita nos bancos de dados PubMed (Medline), Embase e Cochrane. Resultados A tomografia computadorizada apresentou maior sensibilidade para detecção da calcificação patognomônica do que a radiografia simples e facilitou a exclusão de outras condições mais graves, seguiu uma interpretação sistemática composta por cinco elementos-chave. As radiografias simples mostraram sinais inespecíficos de edema dos tecidos moles pré-vertebrais e diminuição da curva lordótica cervical. Entretanto, nenhuma calcificação foi identificada nas radiografias simples. A revisão da literatura produziu 153 artigos com 372 casos. Procedimentos cirúrgicos ou invasivos foram mencionados em 13,7% das publicações e feitos em 28 pacientes. Conclusão A tendinite aguda do músculo longus colli pode mimetizar a apresentação clínica de condições mais graves que necessitam da avaliação do otorrinolaringologista, como doenças infecciosas, traumáticas e neoplásicas. O conhecimento dessa entidade, com seus achados de imagem patognomônica, pode evitar uma terapia clínica mal direcionada e procedimentos invasivos desnecessários.

Miositis del subescapular. Una evolución infrecuente en la tendinopatía calcificada. Estudio de un caso / Subscapularis myositis: An uncommon complication in calcific tendinopathy. A case study

RESUMEN La tendinopatía calcificada del hombro se caracteriza por el depósito de cristales de hidroxiapatita en uno o varios tendones del hombro. Dentro de los procesos que ocurren en esta entidad está la fase de reabsorción, en la que los depósitos podrían migrar hacia estructuras adyacentes. Una muy rara complicación es la migración hacia la unión miotendinosa del tendón correspondiente, la cual provoca una importante reacción inflamatoria muscular que puede objetivarse en pruebas complementarias específicas. Presentamos un caso clínico de una tendinopatía calcificante del subescapular, con pos terior migración hacia la unión miotendinosa causando una miositis del mismo.

ABSTRACT Calcific tendinopathy of the shoulder is characterised by the deposit of hydroxy apatite crys tals in one or more tendons of the shoulder. Within the processes that occur within this disorder, there is the resorption phase, in which the deposits could migrate towards adjacent structures. A very rare complication is the migration towards the myotendinous junction of the corresponding tendon, which causes a significant muscular inflammatory reaction that can be seen in specific complementary tests. A clinical case is presented of a subscapular calcific tendinopathy, with subsequent migra tion to the myotendinous junction, causing myositis of the same.

Photobiostimulation in patients with shoulder impact syndrome. Randomized clinical trial / Fotobioestimulação em pacientes com síndrome do impacto do ombro. Ensaio clínico randomizado

ABSTRACT BACKGROUND AND OBJECTIVES: To evaluate the effects of cluster therapy (Laser+LED) on shoulder impact syndrome, aiming at modulating pain and functionality. METHODS: Clinical, randomized, non double-blind study. Consisting of 28 individuals of both sexes, aged between 18 and 50 years, who were separated into: control group (CG n=13) and treatment group (TG n=15). The volunteers answered the Shoulder Pain and Disability Index (SPADI) questionnaire and goniometric evaluation of three active movements: flexion, abduction, and external rotation. The treatment group was submitted to Fluence Cluster - HTM, with energy of 12.8J, for 1 min and 30 seconds, 3 times a week, for 4 weeks, totaling 12 therapies, in the insertion of the tendon of the supraspinatus muscle and the passage of the long portion of the biceps brachii. The control group received orientation regarding daily activities. RESULTS: In both groups there was a reduction in pain, but the effect size observed was greater for the treatment group In the total SPADI evaluation, treatment presented a significant reduction in values, again with a greater effect size. In active movements, both flexion and external rotation, again the group that used the cluster had advantages, both inferential and in effect sizes. CONCLUSION: The cluster significantly reduced pain and increased functionality in patients with shoulder impingement syndrome.

O grupo controle recebeu orientações quanto às atividades diárias. RESULTADOS: Em ambos os grupos houve redução do quadro álgico, porém o efeito observado foi maior para o grupo tratamento. Na avaliação total do SPADI o grupo tratamento apresentou redução significativa dos valores com maior tamanho de efeito. Nos movimentos ativos, tanto flexão quanto rotação externa, o grupo tratamento apresentou vantagens, tanto de forma inferencial quanto nos tamanhos de efeito. CONCLUSÃO: A fotobioestimulação reduziu de modo significativo a dor e aumentou a funcionalidade dos pacientes com síndrome do impacto do ombro.

Rotura de tendones rotulianos como complicación de mala técnica de aplicación de ondas de presión radial. Reporte de dos casos / Patellar ligament rupture as a complication of poor application technique of radial pressure wave therapy. Report of two cases

RESUMEN La tendinopatía rotuliana se caracteriza por dolor anterior de la rodilla localizado en el polo inferior de la rótula en la unión del tendón rotuliano. Esta es, a menudo, una condición discapacitante que limita la calidad de vida de los pacientes, afecta su capacidad para participar en deportes e incluso dificulta sus actividades cotidianas. El tratamiento de ondas de choque extracorpóreas (ESWT por sus siglas en inglés) ha sido reconocido como una alternativa prometedora y segura para el tratamiento de diversos trastornos musculoesqueléticos, incluida la tendinopatía rotuliana crónica. Sin embargo, existe evidencia limitada con respecto a sus efectos secundarios, en particular las lesiones de tendones asociadas con ESWT. Según el conocimiento de los autores, este es el primer artículo que demuestra evidencia clínica y radiológica de dos pacientes sin factores de riesgo que presentan desgarros parciales del tendón rotuliano después de haber recibido terapia de ondas de presión radiales, también conocida como terapia de ondas de choque radiales, como tratamiento para la tendinopatía rotuliana. El tratamiento con ondas de choque debe ser aplicada por profesionales debidamente capacitados para que se cumplan los requisitos específicos necesarios para garantizar una técnica de aplicación adecuada, minimizar los posibles efectos adversos y mejorar la seguridad del paciente.

ABSTRACT Patellar tendinopathy is characterized by anterior knee pain located at the lower pole of the patella at the junction of the patellar tendon. This is often a disabling condition that limits patients' quality of life, affects their ability to participate in sports, and even hinders their normal daily activities. Extracorporeal shock wave therapy (ESWT) has been recognized as a promising and safe alternative for the treatment of various musculoskeletal disorders - including chronic patellar tendinopathy. However, there is limited evidence regarding its side effects, in particular ESWT-associated tendon injuries. To the authors' knowledge, this is the first report demonstrating clinical and radiological evidence of two patients without known risk factors for partial patellar tendon tears that developed this condition after the application of radial pressure wave therapy - also known as radial shock wave therapy - for patellar tendinopathy. ESWT must be applied by properly trained professionals so that specific requirements needed to guarantee an appropriate application technique, minimize possible adverse effects, and improve patient safety could be met.

Comparison between concentrated bone marrow aspirate and corticoid in gluteal tendinopathy / Comparação entre o aspirado de medula óssea concentrado e o corticóide na tendinopatia glútea

ABSTRACT Objective: To compare bone marrow aspirate concentrate (BMAC) with the standard treatment for gluteal tendinopathies. Methods: 48 patients diagnosed with gluteal tendinopathy at a university hospital were selected by a randomized clinical trial and divided into two groups: (G1) bone marrow aspirate concentrate and (G2) corticosteroid injections. Results: 40 of the 48 selected patients were monitored for six months and both groups showed better scores. Visual analog scale (VAS) scores and Lequesne index were statistically significant higher in patients submitted to BMAC treatment when compared to standard treatment. Both groups improved their quality of life, without statistically significant difference. Conclusion: BMAC constitutes an alternative to gluteal tendinopathy standard treatment, proving to be a safe technique with promising results when combined with multidisciplinary team behavioral therapy. Level of Evidence II, Randomized Clinical Trial.

RESUMO Objetivo: Estudo comparativo entre tratamento com corticóide e aspirado de medula óssea concentrado (BMAC) para o tratamento de tendinopatias glúteas. Métodos: O ensaio clínico randomizado selecionou pacientes diagnosticados com tendinopatia glútea e os dividiu em dois grupos: (G1) aspirado de medula óssea concentrada e (G2) injeção de corticosteróide. Resultados: Foram selecionados 48 pacientes, dos quais 40 foram monitorados por 6 meses, com melhora nos escores nos dois grupos. Os pacientes que foram submetidos ao tratamento com BMAC tiveram uma melhora estatisticamente significativa nos escores de EVA e nos escores de Lequesne em comparação ao tratamento padrão. Houve uma melhora na avaliação da qualidade de vida em ambos os grupos, sem diferença estatisticamente significativa. Conclusão: O aspirado de medula óssea concentrada surge como uma alternativa ao tratamento padrão da tendinopatia glútea, provando ser uma técnica segura e com resultados promissores quando combinada à terapia comportamental de equipe multidisciplinar.

Cross-cultural adaptation and measurement of psychometric properties of the Filipino version of Victorian Institute of Sports Assessment Ankle Instability (VISA-A) questionnaire for achilles tendinopathy

BACKGROUND@#Achilles Tendinopathy (AT) is common in elite and recreational athletes involved in sports such as running and jumping. The severity of this condition can be assessed using the VISA-A questionnaire. However, this is originally developed in English. This has been translated to several languages, but there is no translation and cross-cultural adaptation yet to Filipino. This study aims to translate, cross-culturally adapt the VISA-A questionnaire to Filipino, and examine its psychometric properties.@*METHOD@#The translation and validation process were in accordance with the guidelines set by Beaton et al., and Sousa et al. The psychometric properties were assessed on n= 8 healthy and n= 8 symptomatic athletes.@*RESULTS@#The VISA-A questionnaire exhibited excellent face validity (100% agreement), content validity (Item-Content Validity Index and Scale-Content Validity Index= 1.00), construct validity (U= 2.50, p= 0.001), and concurrent validity (r= 0.90, p= 0.001). The items have good internal consistency (α= 0.80) and showed excellent reliability (ICC= 0.94; 95% CI: 0.73–0.99).@*CONCLUSIONS@#The cross-cultural adaptation of the Filipino version of VISAA (VISA-A-Fil) was successful. Preliminary psychometric testing showed that the VISA-A-Fil questionnaire is a valid and reliable tool that measures the severity of AT. However, there is still a need to explore its full psychometric properties.

Translation to Filipino and validation of the Victorian Institute of Sport Assessment-Patella (VISA-P) questionnaire for patellar tendinopathy

BACKGROUND@#Patellar tendinopathy is an overuse injury characterized by pain on the distal part of the patella caused by specific movement patterns like jumping. To assess the severity of patellar tendinopathy, the self-administered VISA-P questionnaire was developed in the English language. The purpose of this study was to translate and cross-culturally adapt the VISA-P questionnaire into Filipino and determine its psychometric properties.@*METHODS@#A psychometric study design was used in this study. The VISA-P was translated from English to Filipino following the guidelines set by Beaton et al. and Sousa et al. There were six stages: (1) forward translation to Filipino, (2) synthesis, (3) backward translation, (4) expert committee review, (5) pilot testing/cognitive briefing, and (6) preliminary psychometric testing. The psychometric testing was conducted on eight patients with patellar tendinopathy and eight healthy subjects.@*RESULTS@#The Filipino VISA-P questionnaire (VISA-P-Fil) successfully underwent translation and cross-cultural adaptation. It exhibited excellent face, content validity (Item-Content Validity index and Scale-Content Validity Index= 1.00), construct validity (p>0.05, except for Item 6), internal consistency (Cronbach α= 0.81) as well as reliability (ICC= 0.99; 95% CI: 0.994 – 0.999; SEM= 0.42; minimum detectable change at 95% confidence level= 1.79). No ceiling and floor effects were noted for the VISA-PFil.@*CONCLUSION@#In conclusion, the VISA-P-Fil questionnaire was translated and cross-culturally adapted successfully with good validity. Preliminary testing also showed its excellent reliability.

La tendinopatía de la porción larga del Bíceps es causa frecuente de dolor en el hombro. Usualmente esta patología se relaciona con tendinopatía y lesiones del manguito rotador comprometiendo con mayor frecuencia el tendón del subescapular. El diagnóstico de esta entidad es difícil tanto clínica como radiológicamente, y la precisión diagnóstica de las lesiones parciales del Bíceps en Resonancia Nuclear Magnética (RMN) es relativamente baja. El objetivo de la nota técnica es presentar una Tenodesis intra-articular de la porción larga del Bíceps utilizando un anclaje óseo sin nudos, el cual sirve a su vez para reinsertar lesiones de tendón subescapular Laffosse tipo I y II con suturas adicionales.

Long head biceps tendinopathy is a common cause of shoulder pain. Usually, this pathology is related to both, tendinopathy and rotator cuff injuries, most frequently involving the subscapularis tendon. The diagnosis of this entity is difficult clinically and radiologically, and the diagnostic sensitivity and specificity of partial biceps injuries in Magnetic Resonance imaging (MRI) is relatively low. The aim of the technical note is to present an intra-articular tenodesis of the long head of the biceps using a knotless bone anchor, which serves once to reinsert type I and II Laffosse subscapular tendon injuries with additional sutures.
