Proximal tibiofibular joint dislocation treated using flexible and permanent syndesmosis fixation.

We present the case of a 40-year-old man who suffered an isolated proximal tibiofibular dislocation of the left knee after a trauma during a soccer game. Physical examination and radiographic imaging revealed an anterolateral dislocation of the proximal fibula. The diagnosis was confirmed by MRI. The treatment choice was open reduction and internal fixation under direct visualisation using flexible and permanent internal fixation. Postoperative treatment includes knee immobilisation during the first week, and partial weight was allowed for 2 weeks progressing to full weight bearing over 4 weeks. The patient started a gradual and progressive physical therapy programme with range of motion exercises, muscle strengthening and gait training. Full knee range of motion was achieved after 4 weeks. No complaint of pain or hardware discomfort was reported, and the patient is back to daily life and sports activities after 6 months of surgical treatment.

Anatomic Posterolateral Corner Reconstruction With Autografts.

Anatomic posterolateral corner reconstruction reproduces 3 main structures: the lateral collateral ligament, the popliteofibular ligament, and the popliteus tendon. The LaPrade technique reproduces all 3 main stabilizers. However, it requires a long graft, limiting its indication to clinical settings in which allograft tissue is available. We propose a surgical procedure that is a modification of the LaPrade technique using the same tunnel placement, hamstring autografts, and biceps augmentation when necessary. It relies on artificial graft lengthening provided by the loop of the suspensory fixation device fixed at the anterior tibial cortex. The final reconstruction reproduces the popliteus tendon with the bulkiest end of the semitendinosus; the popliteofibular ligament with a strand of the semitendinosus and a strand of the gracilis; and the lateral collateral ligament with a strand of the semitendinosus and a strand of the gracilis, which can also be augmented with a biceps strip.

Outcomes in orthopedics and traumatology: translating research into practice.

Clinical research is focused in generating evidence that is feasible to be applicable to practitioners. However, translating research-focused evidence into practice may be challenging and often misleading. This article aims is to pinpoint these challenges and suggest some methodological safeguards, taking platelet-rich plasma therapies and knee osteochondral injuries as examples. Studies and systematic reviews involving the following concepts will be investigated: clinically relevant outcomes, systematic errors on sample calculation, internal and external validity. Relevant studies on platelet-rich plasma for muscle-tendon lesions and updates on osteochondral lesions treatment were included in this analysis. Authors and clinicians should consider these concepts for the implementation and application of dissemination of the best evidence. Research results should be challenged by a weighted analysis of its methodological soundness and applicability. Level of Evidence V, Therapeutic Studies - Investigating the Results of Treatment.

Updates in biological therapies for knee injuries: anterior cruciate ligament.

There have been many advances in anterior cruciate ligament reconstruction (ACLR) techniques incorporating biological treatment. The aim of this review is to discuss the recent contributions that may enlighten our understanding of biological therapies for anterior cruciate ligament (ACL) injuries and improve management decisions involving these enhancement options. Three main biological procedures will be analyzed: bio-enhanced ACL repair, bio-enhanced ACLR scrutinized under the four basic principles of tissue engineering (scaffolds, cell sources, growth factors/cytokines including platelet-rich plasma, and mechanical stimuli), and remnant-preserving ACLR. There is controversial information regarding remnant-preserving ACLR, since different procedures are grouped under the same designation. A new definition for remnant-preserving ACLR surgery is proposed, dividing it into its three major procedures (selective bundle augmentation, augmentation, and nonfunctional remnant preservation); also, an ACL lesion pattern classification and a treatment algorithm, which will hopefully standardize these terms and procedures for future studies, are presented.

Autologous Osteochondral Transplantation to Treat Patellar Chondral Injuries.

INTRODUCTION: Autologous osteochondral transplantation for the treatment of patellar chondral injuries is a single-stage procedure through a single surgical approach that allows replacement of the chondral injury with an osteochondral plug that has the same cartilaginous hyaline characteristics as the site had before the injury. STEP 1 PREOPERATIVE PLANNING: Make radiographs (anteroposterior, lateral, and Merchant patellofemoral views), computed tomography scans, and magnetic resonance imaging (MRI) of the knee for an anatomic study and to determine cartilage lesion details. STEP 2 PERFORM KNEE ARTHROSCOPY AND LESION IDENTIFICATION: Classify and locate the cartilage lesion on the basis of the intraoperative arthroscopic knee evaluation. STEP 3 USE A PARAPATELLAR APPROACH: Perform a parapatellar incision and patellar eversion as they are necessary to access cartilage lesions. STEP 4 HARVEST THE OSTEOCHONDRAL PLUG AT THE DONATION SITE: Harvest an appropriate osteochondral graft, which is essential for a successful procedure. Perpendicular graft harvesting is crucial for a perfect cartilage surface match. STEP 5 CHARACTERIZE AND PREPARE THE LESION: At this point, prepare the receptor area with a power drill. STEP 6 INSERT THE OSTEOCHONDRAL PLUG INTO THE RECEPTOR SITE: Insert the graft with press-fit fixation. STEP 7 POSTOPERATIVE CARE: Instruct all patients to follow a rehabilitation protocol. RESULTS: Our clinical experience with this procedure has corresponded to the scores and MRI-based findings in our original study, in which we prospectively evaluated thirty-three knees in patients who underwent autologous osteochondral transplantation for a symptomatic full-thickness cartilaginous injury on the patellar articular surface.IndicationsContraindicationsPitfalls & Challenges.

Avaliação dos métodos de mensuração da altura patelar na radiografia digital / Assessment of patellar height measurement methods from digital radiography

OBJETIVO: Analisar os métodos mais comuns de medida da altura patelar e o impacto da experiência do observador na correlação com os outros avaliadores utilizando a radiografia digital. MÉTODOS: Sessenta radiografias digitais do joelho na incidência em perfil foram analisadas por quatro observadores, sendo um médico residente do segundo ano de ortopedia (R2), um médico residente do terceiro ano de ortopedia (R3), um ortopedista especialista em joelho (EJ) e um radiologista especialista na área musculoesquelética (ER). Os índices estudados foram: Insall-Salvati (IS), Blackburne-Peel (BP), Caton-Deschamps (CD) e Insall-Salvati modificado (ISM). Foi calculada a concordância interobservadores por meio do coeficiente de concordância Kappa (κ). RESULTADOS: Os maiores coeficientes de correlação foram obtidos com o método de IS seguido pelo método de CD. A pior correlação foi observada no método de ISM. A maior concordância interobservadores foi obtida entre o ortopedista especialista em joelho e o radiologista especializado na área musculoesquelética nos quatro métodos de aferição utilizados. CONCLUSÃO: Utilizando a radiografia digital, os índices de Insall-Salvati e Caton-Deschamps apresentaram maior concordância interobservadores, sendo esta também influenciada positivamente pela experiência do observador.

OBJECTIVE: To analyze the most common methods for measuring patellar height and the impact of observer experience in correlations with the other observers using digital radiography. METHODS: Sixty digital radiographs of the knee in lateral view were analyzed by four observers: a physician in the second year of medical residence in orthopedics (R2); a physician in the third year of medical residence in orthopedics (R3); an orthopedic surgeon who was a specialist in knee surgery (SK); and a radiologist who was a specialist in musculoskeletal radiology (SR). The indices used were: Insall-Salvati (IS), Blackburne-Peel (BP), Caton-Deschamps (CD) and modified Insall-Salvati (ISM). The interobserver agreement was calculated using the kappa coefficient (k). RESULTS: The highest correlation coefficients were found when using the IS method followed by the CD method. The worst correlation was observed in the ISM method. The highest interobserver agreement was found between the orthopedic surgeon specializing in knee surgery and the radiologist specializing in musculoskeletal radiology, for the four measurement methods used. CONCLUSION: Using digital radiography, the Insall-Salvati and Caton-Deschamps indexes presented the highest interobserver agreement, and this was also positively influenced by the observer's level of experience.

Complicações das endopróteses em pacientes com tumores ósseos do joelho / Endoprostheses-related complications in patients with bone tumors of the knee

As endopróteses não convencionais (ENC) são frequentemente utilizadas na ortopedia oncológica. As complicações do procedimento é motivo de pesquisa, pois há a instituição deste em população jovem e com grande potencial de sobrevida. Nós conduzimos uma revisão da literatura com o objetivo de buscar a melhor evidência científica relativa ao tema. A pesquisa englobou as bases: MEDLINE, EMBASE, CINAHL e o Registro Central Cochrane de ensaios clínicos randomizados (ECR), objetivando identificar estudos reportando complicações, e a substituição ou não da superfície articular da patela. Os estudos foram selecionados de acordo com a melhor qualidade metodológica existente para o assunto. Cento e quarenta e seis (146) estudos foram avaliados. Nenhum ERC foi encontrado. Realizamos uma avaliação qualitativa e quantitativa dos trabalhos encontrados (níveis de evidência IV e V). Utilizou-se o teste de U de Mann-Whitney para a análise estatística. Os resultados apontam para a necessidade de produção de novos estudos, para que se possa chegar a uma conclusão mais sólida. Pode-se considerar altas as taxas de complicações pós ENC, a despeito da baixa qualidade dos estudos, conforme demonstra os estudos existentes na literatura.

Non-conventional endoprostheses (NCE) are frequently used in orthopedic oncology. The complications associated with this procedure have prompted research, due to the fact that it is commonly performed on young patients, with a higher survival rate. We conducted a systematic review of the literature, searching for the best scientific evidence on the subject. The research was carried out in the following databases: MEDLINE, EMBASE, CINAHL and the Cochrane Central Register of randomized controlled trials (CCTR), seeking to identify studies that report complications, and compare patellar resurfacing versus retention. The studies were selected according to the best methodological quality that exists for the subject. One hundred and forty six (146) studies were evaluated. No randomized clinical trial was found. We conducted a qualitative and quantitative evaluation of the work found (evidence levels IV and V). We used the Mann-Whitney U test for the statistical analysis. The results indicate a need for further studies that will enable us to reach a more solid conclusion. The rate of complications after NCE can be considered high, despite the low quality of the studies, as demonstrated by the studies that exist in the literature.

Shoulder functional ratio in elite junior tennis players.

OBJECTIVE: To evaluate shoulder rotation strength and compare the functional ratio between shoulders of elite junior tennis players. DESIGN: This cross-sectional study evaluated muscular rotation performance of 40 junior tennis players (26 male and 14 female) with an isokinetic dynamometer. MAIN OUTCOME MEASURES: Strength variables of external (ER) and internal rotators (IR) in concentric and eccentric modes were considered. For the peak torque functional ratio, the eccentric strength of the ER and the concentric strength of the IR were calculated. RESULTS: All variables related to IR were significantly higher on the dominant compared to the non-dominant side in males and females (p<0.05), but only boys exhibited this dominance effect in ER (p<0.05 and p<0.001). Regarding functional ratios, they were significantly lower for the dominant shoulder (p<0.001) and below 1.00 for both groups, indicating that the eccentric strength of the ER was not greater than the concentric strength of the IR. CONCLUSION: Elite junior tennis players without shoulder injury have shoulder rotation muscle strength imbalances that alter the normal functional ratio between rotator cuff muscles. Although these differences do not seem to affect the athletic performance, detection and prevention with exercise programs at an early age are recommended.

Correlação do tipo de biópsia e sua validade diagnóstica nos tumores músculo-esqueléticos em distintas topografias / Correlation of the type of biopsy and its diagnostic validity in musculoskeletal tumors in different locations

OBJETIVO: O propósito deste estudo foi aquilatar a precisão das biópsias por trefina de Jamshidi, realizadas no Serviço de Ortopedia Oncológica da UNIFESP/EPM, em tumores músculo-esqueléticos, em distintas topografias, tendo como objetivo propor uma classificação para categorizar as biópsias conforme a sua efetividade. MÉTODOS: Foram analisados de modo retrospectivo 107 pacientes que haviam sido biopsiados com agulha de Jamshidi e posteriormente submetidos a ressecção do tumor seguida de exame anatomopatológico da peça cirúrgica. A média de idade dos pacientes foi de 23,5 anos (2,7 a 68,7 anos). Quanto ao sexo, 40,2 por cento eram mulheres e 50,8 por cento homens. Desse universo, 86 apresentavam tumor ósseo (80,4 por cento) e 21, tumor de partes moles (19,6 por cento). Quanto à localização, os tumores encontravam-se preferencialmente nos membros inferiores (72 por cento), seguidos dos membros superiores (22,4 por cento) e pelve (5,6 por cento). Foi proposta conjuntamente uma classificação para categorizar as biópsias conforme o seu resultado em excelente, bom, regular e mau. RESULTADOS: A análise dos dados gerais demonstrou resultados excelentes em 80,4 por cento das biópsias, bons em 8,4 por cento, regulares em 2,8 por cento e ruins em 8,4 por cento. Somando-se os resultados excelentes e bons, encontram-se 88,8 por cento dos casos. Nos casos avaliados, encontraram-se 3,7 por cento de complicações; em nenhum caso a biópsia contra-indicou a cirurgia conservadora com preservação do membro. CONCLUSÃO: As biópsias com agulha de Jamshidi representam método bastante eficiente de diagnóstico das lesões músculo-esqueléticas, com baixo índice de complicações e bons resultados comparáveis aos das biópsias abertas.

OBJECTIVE:The purpose of this study is to evaluate trephine biopsies with Jamshidi needle performed at the Oncologic Orthopedics Service at UNIFESP/EPM, in musculoskeletal tumors in different locations, in order to propose an effectiveness classification of biopsy categories. METHODS: A retrospective analysis was made of 107 patients that had been submitted to biopsy with the Jamshidi needle and later to a tumor resection followed by an anatomopathological exam of the surgical specimen. Mean age of the patients was 23.5 years (2.7 to 68.7 years). Regarding gender, 40.2 percent were female, and 50.8 percent male. In this series, 86 had bone tumor (80.4 percent) and 21 had soft tissue tumors (19.6 percent). With respect to location, tumors were found mainly in the lower limbs (72 percent), followed by upper limbs (22.4 percent), and pelvis (5.6 percent). A joint proposal was prepared to classify biopsy categories according to the excellent, good, regular, and poor result. RESULTS: General data analysis showed excellent results in 80.4 percent of the biopsies, good results in 8.4 percent, regular in 2.8 percent, and poor in 8.4 percent. Adding together excellent and good results, one has 88.8 percent of the cases. In the series, the authors found 3.7 percent of complications, and in no case the biopsy served to rule out conservative surgery with preservation of the limb. CONCLUSION: Biopsies with Jamshidi needle represented quite an efficient diagnostic method for musculoskeletal lesions, with low rate of complications and good results comparable to those of open biopsies.

Avaliação das lesões ortopédicas em tenistas amadores competitivos / Assessment of orthopedic injuries in competitive amateur tennis players

Estudar a incidência de lesões ortopédicas, em tenistas competitivos. Material e métodos: Por meio da análise retrospectiva, 160 tenistas amadores, mas competitivos, do Estado de São Paulo foram estudados. Destes, 64 (40 por cento) eram do sexo feminino e 96 (60 por cento) do masculino. A idade variou de nove a 78 anos, com média de 27,6 anos. Para a análise do material com relação ao número de lesões e ao tipo de lesão apresentada, empregaram-se os critérios da NAIRS (National Athletic Injury Report System) e, para a análise estatística dos dados, utilizou-se o teste t de Student para amostras pareadas, estabelecendo como valor de significância o índice de probabilidade (p) menor do que 0,05. Resultado: Foram relatadas 244 lesões em 122 atletas. Somente 38 (23,8 por cento) tenistas não referiram nenhum tipo de lesão durante a sua vida competitiva. Com relação à região do corpo acometida, a lesão mais freqüente foi a muscular, relatada por 58 (23,8 por cento) tenistas. Logo a seguir foram relatadas as lesões do pé e tornozelo (48-19,7por cento tenistas) e cotovelo (41 - 16,8 por cento - atletas). As patologias específicas mais freqüentemente relatadas foram a epicondilite lateral do cotovelo (epicondilite), relatada por 38 atletas, e as torções do tornozelo (36 relatos). Em média, os tenistas afastaram-se dos treinos e jogos por cinco semanas e quatro dias, porém, este afastamento variou de acordo com o local do organismo acometido pela lesão. As lesões que determinaram maior afastamento das quadras foram as intra-articulares do joelho. Dos atletas que tiveram lesão no joelho, 53,8 por cento submeteram-se a cirurgia e se afastaram do esporte pelo menos por três meses. Conclusões: No tênis, as lesões musculares foram as mais freqüentes, porém, as lesões traumáticas do joelho se mostraram as mais graves e determinaram maior tempo de afastamento das quadras. Não houve diferença estatisticamente significante entre o maior número de torneios disputados ao ano e a maior incidência de lesões. Com relação à epicondilite, na população estudada, não houve diferença estatística entre maior tensão utilizada nas cordas da raquete com a maior incidência da lesão, porém, observou-se que tempo maior de prática do esporte predispõe à lesão. Técnica correta de movimentos básicos parece ser o melhor fator preventivo da epicondilite
