Description of the Anterior Cruciate Ligament Reconstruction Technique with Mini-Lemaire Type Anterolateral Tenodesis through a Single Femoral Tunnel.

The anterior cruciate ligament (ACL) injury causes anteroposterior and rotational instability in the knee. Intra-articular reconstructions often fail to achieve satisfactory rotational control, leading to persistent complaints of instability and subjecting the neo-ligament to increased stress. Young patients with high athletic demands and grade 2 or 3 pivot-shift often have a higher risk of re-rupture after isolated ACL reconstruction. Over the years, various techniques have been developed to address such situations. Among the described techniques, one of the most commonly used is the modified or "mini-Lemaire" lateral extra-articular tenodesis. Biomechanical studies demonstrate the versatility of the technique due to its relatively isometric behavior in flexion angles of 0-60° when the graft is introduced deeply to the lateral collateral ligament. It offers the possibility of fixation at different anatomical positions on the lateral femoral condyle and at different degrees of flexion. The objective of this study is to describe an accessible, reproducible technique that relies on materials widely available in our environment.

Minimally Invasive Peroneal Tenodesis Assisted by Peroneal Tendoscopy: Technique and Preliminary Results.

Introduction: Peroneal disorders are a common cause of ankle pain and lateral instability and have been described in as much as 77% of patients with lateral ankle instability. Clicking, swelling, pain, and tenderness in the peroneal tendons track are frequent symptoms, but they can be confused with other causes of lateral ankle pain. The management of peroneal disorders can be conservative or surgical. When the conservative treatment fails, surgery is indicated, and open or tendoscopic synovectomy, tubularization, tenodesis or tendon transfers can be performed. The authors present a surgical technique of tendoscopy associated to minimally invasive tenodesis for the treatment of peroneal tendon tears, as well as the preliminary results of patients submitted to this procedure. Methods: Four patients with chronic lateral ankle pain who were diagnosed with peroneal brevis pathology were treated between 2020 and 2022 with tendoscopic-assisted minimally invasive synovectomy and tenodesis. Using a 2.7 mm 30° arthroscope and a 3.0 mm shaver blade, the entire length of the peroneus brevis tendon and most parts of the peroneus longus tendon can be assessed within Sammarco's zones 1 and 2. After the inspection and synovectomy, a minimally invasive tenodesis is performed. Results: All patients were evaluated at least six months after surgery. All of them reported improvement in daily activities and in the Foot Function Index (FFI) questionnaire (pre-surgery mean FFI = 23.86%; post-surgery mean FFI = 6.15%), with no soft tissue complications or sural nerve complaints. Conclusion: The tendoscopy of the peroneal tendons allows the surgeon to assess their integrity, confirm the extent of the lesion, perform synovectomy, prepare the tendon for tenodesis, and perform it in a safe and minimally invasive way, reducing the risks inherent to the open procedure.

Combined Anterior Cruciate Ligament Reconstruction (ACLR) and Lateral Extra-articular Tenodesis through the Modified Lemaire Technique versus Isolated ACLR: A Meta-analysis of Clinical Outcomes / Reconstrução combinada do ligamento cruzado anterior (RLCA) e tenodese extra-articular lateral pela técnica de Lemaire modificada versus RLCA isolada: Uma metanálise dos resultados clínicos

Abstract Objective Lateral extra-articular tenodesis (LET) has been proposed to resolve rotatory instability following anterior cruciate ligament reconstruction (ACLR). The present meta-analysis aimed to compare the clinical outcomes of ACLR and ACLR with LET using the modified Lemaire technique. Materials and Methods We performed a meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) staement. The literature search was performed on the PubMed, EBSCOHost, Scopus, ScienceDirect, and WileyOnline databases. The data extracted from the studies included were the study characteristics, the failure rate (graft or clinical failure) as the primary outcome, and the functional score as the secondary outcome. Comparisons were made between the patients who underwent isolated ACLR (ACLR group) and those submitted to ACLR and LET through the modified Lemaire technique (ACLR + LET group). Results A total of 5 studies including 797 patients were evaluated. The ACLR + LET group presented a lower risk of failure and lower rate of rerupture than the ACLR group (risk ratio [RR] = 0.44; 95% confidence interval [95%CI]: 0.26 to 0.75; I2 = 9%; p = 0.003). The ACLR + LET group presented higher scores on the Knee Injury and Osteoarthritis Outcome Score (KOOS) regarding the following outcomes: pain, activities of daily living (ADL), sports, and quality of life (QOL), with mean differences of 0.20 (95%CI: 0.10 to 0.30; I2 = 0%; p < 0.0001), -0.20 (95%CI: -0.26 to -0.13; I2 = 0%; p < 0.00001), 0.20 (95%CI: 0.02 to 0.38; I2 = 0%; p = 0.03), and 0.50 (95%CI: 0.29 to 0.71; I2 = 0%; p < 0.00001) respectively when compared with the ACLR group. Conclusion Adding LET through the modified Lemaire technique to ACLR may improve knee stability because of the lower rate of graft rerupture and the superiority in terms of clinical outcomes. Level of Evidence I.

Foram feitas comparações entre os pacientes submetidos apenas à RLCA (grupo RLCA) e à RLCA e TEL pela técnica de Lemaire modificada (grupo RLCA + TEL). Resultados Foram avaliados 5 estudos que incluíam 797 pacientes. O grupo RLCA + TEL apresentou um risco menor de falha e menor taxa de rerruptura do que o grupo RLCA (razão de risco [RR] = 0,44; intervalo de confiança de 95% [IC95%] 0,26 a 0,75; I2 = 9%; p = 0,003). O grupo RLCA + TEL obteve pontuações maiores no Escore de Desfechos de Osteoartrite e Lesão no Joelho (Knee Injury and Osteoarthritis Outcome Score, KOOS, em inglês) com relação aos seguintes desfechos: dor, atividades cotidianas (AC), esportes, e qualidade de vida (QV), com diferenças médias de 0,20 (IC95%: 0,10 a 0,30; I2 = 0%; p < 0,0001), -0.20 (IC95%: -0,26 a-0,13; I2 =0%; p < 0,00001), 0,20 (IC95%: 0,02 a 0,38; I2 = 0%; p = 0,03) e 0,50 (IC95%: 0,29 a 0,71; I2 = 0%; p < 0,00001), respectivamente, quando comparado com o grupo RLCA. Conclusão O acréscimo de TEL pela técnica de Lemaire modificada à RLCA pode melhorar a estabilidade do joelho devido à menor taxa de rerruptura do enxerto e à superioridade dos resultados clínicos. Nível de evidência I.

Description of the Anterior Cruciate Ligament Reconstruction Technique with Mini-Lemaire Type Anterolateral Tenodesis through a Single Femoral Tunnel / Descrição de técnica de reconstrução do ligamento cruzado anterior com tenodese ântero-lateral tipo mini-Lemaire através de túnel único femoral

Abstract The anterior cruciate ligament (ACL) injury causes anteroposterior and rotational instability in the knee. Intra-articular reconstructions often fail to achieve satisfactory rotational control, leading to persistent complaints of instability and subjecting the neo-ligament to increased stress.

Resumo A lesão do ligamento cruzado anterior (LCA) causa instabilidade anteroposterior e rotatória do joelho. Reconstruções isoladas intra-articulares muitas vezes não obtêm controle rotacional satisfatório, mantendo queixa de instabilidade e impondo ao neoligamento um maior estresse. Pacientes jovens, com alta demanda atlética e com pivot-shift grau 2 ou 3 apresentam um maior risco de rerrotura após reconstrução isolada do LCA. Ao longo dos anos diversas técnicas foram desenvolvidas na tentativa de mitigar tais situações. Dentre as técnicas descritas, uma das mais utilizadas é a Tenodese extra-articular Lateral tipo Lemaire modificada ou "mini-Lemaire". Estudos biomecânicos demonstram versatilidade da técnica devido a seu comportamento relativamente isométrico em graus de flexão de 0-60° quando a fita é introduzida profundamente ao ligamento colateral lateral, com possibilidade de fixação em diferentes posições anatômicas no côndilo femoral lateral e em diferentes graus de flexão. O objetivo do estudo é descrever uma técnica acessível, reprodutível e dependente de material amplamente disponível em nosso meio.

Uso de balón subacromial en lesión masiva irreparable del manguito rotador

La lesión del manguito rotador es una causa importante de dolor y disfunción del hombro. El tratamiento de las roturas masivas e irreparables del manguito rotador sigue siendo un gran reto para los ortopedistas por su complejidad y severidad. Una de las alternativas prometedoras para su manejo es el uso del balón subacromial. Presentamos el caso de una mujer de 67 años con diagnóstico de rotura masiva e irreparable del manguito rotador en el hombro derecho (grado III de Patte, grado IV Goutallier y grado II de Hamada) sin artrosis glenohumeral, tenosinovitis del bíceps y subescapular íntegro. La escala de constant preoperatorio fue de 40 puntos. Se realizó una reparación parcial artroscópica del tendón supraespinoso e infraespinoso asociado a una tenodesis suprapectoral del bíceps y la colocación del balón subacromial. La paciente realizó rehabilitación con mejoría de los arcos de movilidad, disminución del dolor e incremento de la fuerza del hombro derecho. La escala de constant postoperatorio fue de 80 puntos a la semana doce. El balón subacromial es una buena alternativa de tratamiento para las lesiones irreparables del manguito rotador con resultados óptimos a corto plazo en cuanto a dolor y función.

The rotator cuff injury is a significant cause of shoulder pain and dysfunction. Treating massive and irreparable rotator cuff tears remains a major challenge for orthopedists due to their complexity and severity. One promising alternative for managing these cases is the use of subacromial balloons. In this study, we present the case of a 67-year-old woman diagnosed with a massive and irreparable rotator cuff tear in her right shoulder (Grade III Patte, Grade IV Goutallier, and Grade II Hamada), without glenohumeral arthritis, intact biceps tenosynovitis, and subscapularis. The preoperative Constant score was 40 points. The patient underwent partial arthroscopic repair of the supraspinatus and infraspinatus tendons, along with a suprapectoral biceps tenodesis and subacromial balloon placement. Postoperative rehabilitation led to improved range of motion, reduced pain, and increased strength in the right shoulder. The postoperative Constant score reached 80 points at the twelve-week mark. The subacromial balloon proves to be a promising treatment alternative for irreparable rotator cuff injuries, providing optimal short-term results in terms of pain relief and functionality.

Superior labral anterior and posterior (SLAP) lesions of the long bicep insertion on the glenoid: management in athletes.

INTRODUCTION: SLAP injuries are common in athletes but there is no consensus on different aspects such as pathophysiology and treatment options. Currently, the main controversy in the treatment of SLAP II injuries is deciding whether to make a repair or tenodesis. Clinical outcomes have varied according to the patients' age, sports, or work activity. This review aims to present the evidence at points of contention regarding pathophysiology, treatment options, outcomes, return to activities, and complications of type II SLAP. MATERIAL AND METHODS: The relevant literature on SLAP injuries and their treatment options and results were identified from PubMed and a narrative review was performed. RESULTS: Repairing SLAP II injuries seems to show better outcomes in younger patients and athletes who perform overhead movements, while tenodesis (in its various technical options) yields better outcomes in older patients, both as a single injury or associated with other pathologies such as rotator cuff injury or tenosynovitis. On the other hand, there currently seems to be a trend of increasing the indication of tenodesis even in underage patients and athletes, given that there are reports of fewer re-operations and a faster recovery. CONCLUSION: The evidence is unclear as to which factors influence the failure to achieve optimal outcomes even in cases with anatomical repairs. Studies with a high level of evidence including different variables are necessary to define when to repair, perform tenodesis, and what surgical technique to use for both options.

Biceps tenotomy or tenodesis in association with rotator cuff repair: is there an influence on functional results? A retrospective cohort study

ABSTRACT BACKGROUND: Instability or tears of the long head of the biceps tendon (LHBT) may be present in more than 35% of rotator cuff repairs (RCR). OBJECTIVE: To compare clinical results from patients undergoing arthroscopic RCR, according to the procedure performed at the LHBT. DESIGN AND SETTING: Retrospective cohort study designed at the shoulder and elbow clinic of Instituto de Ortopedia e Traumatologia, Hospital das Clinicas, Faculdade de Medicina, Universidade de Sao Paulo, Brazil. METHODS: Functional results among patients were compared using the American Shoulder and Elbow Surgeons (ASES) and University of California Los Angeles (UCLA) scales, according to the LHBT approach adopted: no procedure, tenotomy or tenodesis. RESULTS: We evaluated 306 shoulders (289 patients): 133 underwent no procedure at the LHBT, 77 tenotomy and 96 tenodesis. The ASES scale at 24 months showed no difference (P = 0.566) between the groups without LHBT procedure (median 90.0; interquartile range, IQR 29), tenotomy (median 90.0; IQR 32.1) or tenodesis (median 94.4; IQR 22.7); nor did the UCLA scale (median 33; IQR 7 versus median 31; IQR 8 versus median 33; IQR 5, respectively, P = 0.054). The groups differed in the preoperative functional assessment according to the ASES and UCLA scale, such that the tenodesis group started from higher values. However, there was no difference in pre and postoperative scores between the groups. CONCLUSION: Tenodesis or tenotomy of the LHBT, in the sample analyzed, did not influence the clinical results from RCR, as assessed using the ASES and UCLA scales.

Functional Outcome of Lateral Extraarticular Tenodesis (LET) Procedure in Addition to Anterior Cruciate Ligament Reconstruction: A Metaanalysis / Resultado funcional do procedimento de tenodese extra-articular lateral (TEL) como complemento à reconstrução do ligamento cruzado anterior: Uma metanálise

Abstract Objectives The aim of the present study is to systematically review and analyze the functional outcome of lateral extraarticular tenodesis (LET) procedure in addition to anterior cruciate ligament reconstruction (ACLR) in studies with a high level of evidence. Methods We performed a literature search for clinical studies comparing the LET method as an augmentation to ACL reconstruction with ACL reconstruction alone. The primary outcomes were the International Knee Documentation Committee (IKDC) score, the Lysholm score, and graft failures. Continuous variables were reported as means and 95% confidence intervals (CIs). Results Six clinical studies with 1,049 patients were included in the metaanalysis. The follow-up period was, in average, 24 months (range, 6-63 months). The addition of the LET procedure to ACLR results in better functional outcome based on the IKDC score (p< 0.05). Graft failure was found to be lower in the ACLR plus LET group (16 of 342 patients) compared with the ACLR-only group (46 of 341 patients) (p< 0.05). Conclusion There is high-level evidence that LET procedure in addition to ACLR is preferable in terms of functional outcome and graft failure.

Resumo Objetivos O objetivo deste estudo é revisar e analisar sistematicamente o desfecho funcional do procedimento de tenodese extra-articular lateral (TEL) em complemento à reconstrução do ligamento cruzado anterior (RLCA) em de estudos com alto nível de evidências. Métodos Realizamos a pesquisa bibliográfica para estudos clínicos comparando o método TEL como complemento à RCLA com a RLCA isolada. Os resultados principais foram a pontuação no Comitê Internacional de Documentação de Joelho (IKDC, na sigla em inglês), pontuação de Lysholm, e falhas no enxerto. Variáveis contínuas foram relatadas, como médias e intervalos de confiança (ICs) de 95%. Resultados Seis estudos clínicos com 1,049 pacientes foram incluídos na metanálise. O período de seguimento foi de, em média, 24 meses (intervalo de 6-63 meses). A adição do procedimento TEL à reconstrução do LCA resultou em melhor resultado funcional com base no escore IKDC (p< 0,05). A falha do enxerto foi menor no grupo RLCA mais TEL (16 dos 342 pacientes) em comparação com o grupo apenas RLCA (46 dos 341 pacientes) (p< 0,05). Conclusão Há evidências de alto nível de que o procedimento TEL como complemento à RLCA é preferível em termos de resultado funcional e falha do enxerto.

Evaluation of Biceps Tenotomy or Tenodesis on Fatty Infiltration of the Biceps Muscle.

Objective The objective of the present study was to determine whether there is fatty infiltration (FI) of the biceps brachii muscle mass after tenotomy or tenodesis for the treatment of tendon injuries in the long head of the biceps and to establish a relationship between FI with changes in the length of muscle fibers. Methods Clinical and imaging analysis of 2 groups of patients (biceps tenodesis [16 patients] and biceps tenotomy [15 patients]). In both groups, we compared the findings on the contralateral side of each patient (control group). All patients had undergone unilateral biceps tenodesis or tenotomy, with postoperative follow-up of > 1 year. Magnetic resonance imaging (MRI) was performed on both arms of each patient following a specific protocol. Strength of elbow flexion was measured with a manual dynamometer, and the results were subjected to statistical analysis. Results The mean postoperative period before the MRI was 5 years, and no case of FI was observed in the anterior compartment of either arm of the evaluated patients. Seven patients had moderate or severe deformity in the operated arm. We found no significant relationship between arm deformity ( p = 0.077), flexion strength percentage ( p = 0.07) or pain on palpation of the bicipital groove ( p = 0.103). Conclusion None of the evaluated patients had evidence of FI in the muscle mass of the anterior arm compartment after the procedures. It was not possible to establish a correlation between the discrepancy of the biceps muscle length measured by MRI and the presence of FI in the anterior compartment of the arm.

Resumo Objetivo O objetivo do presente estudo foi determinar a existência de infiltração gordurosa (IG) na massa muscular do bíceps braquial após a tenotomia ou tenodese para tratamento de lesão no tendão da cabeça longa do bíceps e estabelecer uma relação entre a IG e alterações no comprimento das fibras musculares. Métodos Análise clínica e de imagens de 2 grupos de pacientes (submetidos à tenodese do bíceps [16 indivíduos] ou tenotomia do bíceps [15 indivíduos]). Nos dois grupos, os achados foram comparados àqueles do lado contralateral de cada indivíduo (grupo controle). Todos os pacientes foram submetidos à tenodese ou tenotomia unilateral do bíceps, com acompanhamento pós-operatório > 1 ano. Exames de ressonância magnética (RM) foram realizados em ambos os braços de cada paciente de acordo com um protocolo específico. A força de flexão do cotovelo foi medida com dinamômetro manual e os resultados foram submetidos à análise estatística. Resultados O período pós-operatório médio antes da realização da RM foi de 5 anos, e nenhum caso de IG foi observado no compartimento anterior de ambos os braços dos pacientes avaliados. Sete pacientes apresentaram deformidade moderada ou grave no braço operado. Não houve relação significativa entre deformidade do braço (p = 0,077), percentual de força de flexão (p = 0,07) ou dor à palpação do sulco bicipital (p = 0,103). Conclusão Nenhum dos pacientes avaliados apresentou evidência de IG na massa muscular do compartimento anterior do braço após os procedimentos. Não foi possível estabelecer uma correlação entre a discrepância do comprimento do músculo bíceps, medido à RM, e a presença de IG no compartimento anterior do braço.

Effect of Modified Lemaire Anterolateral Extra-articular Tenodesis on the Magnetic Resonance Imaging Maturity Signal of Anterior Cruciate Ligament Hamstring Graft.

BACKGROUND: Lateral extra-articular tenodesis (LET) is one of the most widely used procedures to restore anterolateral stability. Clinical outcomes after the addition of LET to anterior cruciate ligament (ACL) reconstruction (ACLR) have been widely investigated; however, the potential influence of LET on the ACL ligamentization process has not been examined. PURPOSE/HYPOTHESIS: The purpose was to use 10-month postoperative magnetic resonance imaging (MRI) scans to determine whether the maturity of grafts after hamstring autograft ACLR was affected by concomitant LET. The hypothesis was that when modified Lemaire lateral extra-articular tenodesis (MLLET) was performed, the MRI parameters of ACL graft maturity would be modified. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: The study included patients treated between December 2017 and December 2018 who had undergone anatomic 3-strand hamstring tendon autograft ACLR, with or without concomitant MLLET, and had undergone MRI 10 months postoperatively. Thus, the study included 30 patients who had isolated ACLR and 22 patients who had ACLR plus MLLET. The 2 groups were comparable based on all criteria analyzed. To evaluate graft maturity, the signal-to-noise quotient (SNQ) was measured in 3 regions of interest of the proximal, midsubstance, and distal ACL graft. Lower SNQ ratios indicate less water content and, theoretically, better maturity and healing of the graft. RESULTS: The mean ± SD for SNQ was 4.62 ± 4.29 (range, 3.12-6.19) in the isolated ACLR group and 7.59 ± 4.68 (range, 4.38-8.04) in the ACLR plus MLLET group (P = .012). Upon comparing the mean values of the 3 portions between the 2 groups, we found a significant difference between the 2 groups for the proximal and middle portions (P = .007 and P = .049, respectively) but no difference in the distal portion (P = .369). CONCLUSION: At the 10-month follow-up, hamstring tendon autografts for anatomic ACLR with MLLET did not show the same MRI signal intensity compared with isolated hamstring anatomic ACLR.

Tenodesis intrarticular del bíceps y reparacion simultanea de lesiones de subescapular laffosse I y II con anclaje sin nudos. Nota técnica / Intraarticular biceps tenodesis and simultaneous subscapularis lafosse type I or II repair with knotless anchor. Technical Note

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.

Intra-articular arthroscopic biceps tenodesis with interference screw: clinical and isokinetic evaluation.

BACKGROUND: Although biceps tenodesis has been widely used to treat its pathologies, few studies looked at the objective evaluation of elbow strength after this procedure. The purpose of this study is to clinically evaluate patients submitted to long head of the biceps (LHB) tenodesis with interference screws through an intra-articular approach and analyze the results of an isokinetic test to measure elbow flexion and forearm supination strengths. METHODS: Patients who had biceps tenodesis were included in the study if they had a minimum follow-up of 24 months. Patients were excluded if they had concomitant irreparable cuff tears or previous or current contralateral shoulder pain or weakness. Postoperative evaluation was based on University of California-Los Angeles (UCLA) shoulder score and on measurements of elbow flexion and supination strength, using an isokinetic dynamometer. Tests were conducted in both arms, with velocity set at 60º/s with 5 concentric-concentric repetitions. RESULTS: Thirty-three patients were included and the most common concomitant diagnosis were rotator cuff tear (69%) and superior labrum anterior to posterior (SLAP) lesions (28%). The average UCLA score improved from 15.1 preoperatively to 31.9 in the final follow-up (P < .001). Isokinetic tests showed no difference in peak torque between the upper limbs. One patient had residual pain in the biceps groove. None of the patients had Popeye deformity. UCLA score and follow-up length did not demonstrate correlation with peak torque. CONCLUSION: Arthroscopic proximal biceps tenodesis with interference screw, close to the articular margin, yielded good clinical results. Isokinetic tests revealed no difference to the contralateral side in peak torque for both supination and elbow flexion.

Supraspinatus Muscle Tendon Lesion and Its Relationship with Long Head of the Biceps Lesion.

Objective To identify the clinical, radiological, and arthroscopic correlation of long head of the biceps tendon injuries and their influence on pain when associated with rotator cuff injuries. Methods Between April and December 2013, 50 patients were evaluated, including 38 (76%) women and 12 (24%) men, with a mean age of 65.1 years old. The patients were operated by the Shoulder and Elbow Group, Discipline of Sports Medicine, Orthopedics and Traumatology Department, Universidade Federal de São Paulo. The subjects underwent repair of the rotator cuff lesion with clinical, radiological and/or arthroscopic evidence of involvement of the long head of the biceps tendon. Results An association between pain at palpation of the intertubercular groove of the humerus and high-grade partial lesions (partial rupture of the tendon affecting more than 50% of its structure) was observed at the arthroscopy ( p = 0.003). There was also an association between the high-grade lesion of the long head of the biceps and injury to the supraspinatus muscle tendon ( p < 0.05). For each centimeter of the supraspinatus muscle tendon injury, the patient presented a 1.7 higher probability of having a high-grade lesion at the long head of the biceps. Conclusion Pain at the anterior shoulder region during palpation of the intertubercular groove of the humerus may be related to high-grade lesions to the long head of the biceps. Rotator cuff injury and its size are risk factors for high-grade injuries to the long head of the biceps tendon.

Resumo Objetivo Identificar a correlação clínica, radiológica, e artroscópica das lesões do tendão da cabeça longa do bíceps e sua influência na dor do paciente quando associada às lesões do manguito rotador. Métodos Entre abril e dezembro de 2013, foram avaliados 50 pacientes, sendo 38 (76%) do sexo feminino e 12 (24%) do sexo masculino, com idade média de 65,1 anos. Os pacientes foram operados pelo Grupo de Ombro e Cotovelo da Disciplina de Medicina Esportiva do Departamento de Ortopedia e Traumatologia da Universidade Federal de São Paulo. Os indivíduos foram submetidos a reparo da lesão do manguito rotador com evidência clínica, radiológica e/ou artroscópica de acometimento do tendão da cabeça longa do bíceps. Resultados Observou-se associação entre dor à palpação do sulco intertubercular do úmero com lesão parcial de alto grau (ruptura parcial acometendo mais de 50% do tendão) na artroscopia (p = 0,003). Encontramos ainda uma associação entre a lesão de alto grau da cabeça longa do bíceps e a lesão do tendão do músculo supraespinal (p < 0,05), sendo que, para cada centímetro de lesão do tendão do músculo supraespinal, o paciente apresenta probabilidade 1,7 maior de ter uma lesão de alto grau da cabeça longa do bíceps. Conclusão A dor na região anterior do ombro à palpação do sulco intertubercular do úmero pode estar relacionada às lesões de alto grau da cabeça longa do bíceps. A lesão do manguito rotador e o seu tamanho são fatores de risco para lesão de alto grau do tendão da cabeça longa do bíceps.

Minimally invasive tenodesis for peroneus longus tendon rupture: A case report and review of literature.

BACKGROUND: Peroneal tendon disorders are common causes of lateral hindfoot pain. However, total rupture of the peroneal longus tendon is rare. Surgical treatment for this condition is usually a side-to-side tenodesis of the peroneal longus tendon to the peroneal brevis tendon. While the traditional procedure involves a long lateral curved incision, this approach is associated with damage to the lateral soft tissues (up to 24% incidence). CASE SUMMARY: A 50-year-old female had developed pain at the lateral aspect of the hindfoot 1 mo after an ankle sprain while walking in the street. Previous treatments were anti-inflammatory drugs, ice, rest and Cam-walker boot. At physical exam, there was pain and swelling over the course of the peroneal tendons. Ankle instability and cavovarus foot deformity were ruled out. Eversion strength was weak (4/5). Imaging showed complete rupture of the peroneal longus tendon associated with a sharp hypertrophic peroneal tubercle. Surgical repair was indicated after failure of conservative treatment (physiotherapy, rest, analgesics, and ankle stabilizer). A less invasive approach was performed for peroneal longus tendon debridement and side-to-side tenodesis to the adjacent peroneal brevis tendon, with successful clinical and functional outcomes. CONCLUSION: Peroneus longus tendon tenodesis can be performed through a less invasive approach with preservation of the lateral soft tissue integrity.
