RESUMO

To analyze the prevalence and characteristics of late postoperative complications of orthopedic surgeries by video arthroscopy.This was a descriptive cross-sectional study that evaluated, through its own instrument, local and systemic postoperative complications of patients undergoing orthopedic surgeries by video arthroscopy. The study included 270 patients, who were evaluated on days 30(without prosthesis) and 90(with prosthesis placement) of the postoperative period, by telephone service. The selection of participants occurred sequentially and population-based, within the data collection period, from February to July 2020, in a large hospital for medium and high complexity surgeries. Of the 270 procedures performed in the period, 4.4% (n = 12) presented late postoperative infection. The most frequent complications were erythema (83%), edema (75%) and secretion (67%) in the surgical wound. Most used antibiotic therapy (92%) and anti-inflammatory drugs (67%). Hospital readmission was not necessary concerning the complications. Only 50% required medical evaluation before the scheduled time.The need for practices that ensure the quality of perioperative care and improve the active search to assess surgical outcomes is reinforced.

RESUMO

INTRODUCTION: Despite the widespread use of arthroscopic double-row transosseous-equivalent (TOE) rotator cuff repair (RCR) techniques, midterm outcome data are limited. The purpose of this article was to assess midterm clinical outcomes of patients following arthroscopic TOE RCR using either a knotless tape bridge (TB) repair or knotted suture bridge (SB) repair technique. We hypothesized that there would be significant improvements in patient-reported outcomes with TOE RCR that would be durable over time. We also hypothesized that the knotless TB technique would yield equivalent clinical results to the knotted SB technique, but that there would be differences in retear types between the two TOE techniques. METHODS: Patients included were a minimum of 5 years from an index arthroscopic double-row TOE repair using either a knotless TB or knotted SB technique for one, two, or three tendon full-thickness rotator cuff tears involving the supraspinatus tendon. Preoperative and postoperative American Shoulder and Elbow Surgeons, Short-Form 12 Physical Component Summary, Quick Disabilities of the Arm, Shoulder, and Hand, Single Assessment Numeric Evaluation, and satisfaction scores were collected. Scores were also stratified and compared based on primary and revision repair, tear location, and tear chronicity. Outcomes between techniques were contrasted, and survivorship analysis was conducted, with failure defined as progression to revision surgery. RESULTS: One-hundred ninety-two shoulders were included with a mean follow-up of 6.6 years (range, 5.0 to 11.0 years). Fifteen shoulders (7.8%) underwent revision cuff repair. All scores improved significantly for TB repair (P < 0.001). For SB repair, all scores improved, but only American Shoulder and Elbow Surgeons and Short-Form 12 Physical Component Summary scores (P < 0.05) demonstrated statistical significance. No statistically significant differences were found between the repair techniques when stratified by primary and revision repairs, tear location, or chronicity. Postoperative clinical survivorship was 96.6% and 93.6% for knotted SB repairs and 96.7% and 93.9% for knotless TB repairs at 2 and 5 years, respectively. CONCLUSION: TOE RCR results in significant clinical improvement and excellent survivorship at a minimum of 5 years of follow-up, using either knotted SB or knotless TB repair techniques in primary and revision cases and in small and large tears. Equivalent results were obtained with both TOE techniques. Patients undergoing repair with a TOE showed significant improvements in patient-reported outcomes that were durable at a minimum of 5 years postoperatively.

RESUMO

CONTEXTO CLÍNICO: El dolor de cadera es una consulta traumatológica frecuente con múltiples causas posibles, ya sean articulares, extrarticulares o dolor referido, muchas de las cuales son pasibles de tratamiento com artroscopia de cadera. La anamnesis y el examen físico orientan el diagnóstico, que habitualmente se confirma con métodos por imagen. La artroscopia de cadera es un procedimiento que se realiza con mayor frecuencia para tratar diversas patologías de esta articulación. El pinzamiento femoro-acetabular (PFA), también llamado atrapamiento o choque femoro-acetabular o en inglés femoroacetabular impingement, se produce por un roce o choque anormal entre la cabeza del fémur y el acetábulo. La causa de una alteración en la forma del fémur (PFA tipo leva o "cam"), del acetábulo (PFA tipo pinza o "pincer") o ambas (PFA tipo mixta). La prevalencia radiológica de estas alteraciones es del 10-15%, aunque sólo un porcentaje mínimo producen síntomas y complicaciones. El 75% de los pacientes en los que se diagnostica esta patología son adultos jóvenes que practican un deporte con asiduidad, especialmente los que suponen flexión de la cadera y/o impacto sobre ella (p. ej. salto de vallas, gimnasia o artes marciales). El síntoma inicial es el dolor, el cual puede localizarse en la ingle, en la zona lateral o posterolateral de la cadera comprometida. Además, pueden presentarse resaltos o restricción en algunos movimientos. Si se prolonga en el tiempo, el PFA puede producir daño articular y artrosis traumática, con limitación funcional y la posibilidad de requerir un reemplazo de cadera. Los pacientes con clínica de PFA, sin respuesta al tratamiento conservador y sin evidencia clara de artrosis serían candidatos a una corrección quirúrgica. TECNOLOGÍA: La artroscopia de cadera es un procedimiento quirúrgico que se realiza con anestesia general. La correcta posición del paciente (y por lo tanto se debe disponer de camillas multi-posición), con tracción del miembro, es importante para la realización del procedimiento. Bajo guía radioscópica se colocan, un puerto (acceso) para la óptica y uno o dos puertos adicionales de trabajo por donde entra el instrumental que realizará los diferentes gestos quirúrgicos (desbridamiento, resección, biopsia). OBJETIVO: El objetivo del presente informe es evaluar la evidencia disponible acerca de la eficacia, seguridad y aspectos relacionados a las políticas de cobertura del uso de artroscopia de cadera. MÉTODOS: Se realizó una búsqueda en las principales bases de datos bibliográficas, en buscadores genéricos de internet, y financiadores de salud. Se priorizó la inclusión de revisiones sistemáticas (RS), ensayos clínicos controlados aleatorizados (ECAs), evaluaciones de tecnologías sanitarias (ETS), evaluaciones económicas, guías de práctica clínica (GPC) y políticas de cobertura de diferentes sistemas de salud. RESULTADOS: Se incluyeron 3 ECAs, 4 RS, 1 ETS, 2 evaluaciones económicas, y 14 informes de políticas de cobertura de artroscopia de cadera. CONCLUSIONES: Evidencia de muy baja calidad no permite establecer conclusiones acerca de la efectividad comparativa entre la cirugía artroscópica o la cirugía abierta para para el pinzamiento femoroacetabular. Evidencia de moderada calidad (por imprecisión y riesgo de sesgos) sobre el tratamiento quirúrgico mediante artroscopia de cadera en comparación con rehabilitación física estructurada para el tratamiento del pinzamiento femoro-acetabular sugiere que mejora levemente la calidad de vida al año de seguimiento. Evidencia de muy baja calidad no permite establecer conclusiones sobre la eficacia de la artroscopia de cadera para el tratamiento de lesiones de labrum, displasia de cadera, enfermedades sinoviales, desgarro del músculo aductor, lesiones del ligamento teres, artritis séptica, defectos condrales, retroversión acetabular, osteomas osteoides o trauma. No se encontraron guías de práctica clínica que mencionen esta tecnología. Las asseguradoras estadounidenses relevadas cubren, tanto la artroscopia como la cirugía abierta, para el tratamento de casos seleccionados de pinzamiento femoro-acetabular; algunas de estas aseguradoras también cubren estos procedimientos para otras indicaciones. El sistema de salud de Reino Unido cubre la artroscopia para pinzamiento femoro-acetabular. El resto de los financiadores de Latinoamérica y países de altos ingresos relevados no mencionan su uso. No se encontraron evaluaciones económicas en la región que evalúen esta tecnología.

RESUMO

Instability is a common sequela after repeated ankle sprains. When nonoperative treatment fails, open lateral ligament complex repair and reinforcement with the inferior extensor retinaculum has been the gold standard procedure. The recent advancements in arthroscopic techniques have created comparable biomechanical and functional results to open procedures. The authors' modification to the standard arthroscopic technique permits ligament approximation to the distal fibula over a larger surface area, using knotless anchors to avoid the need of an accessory portal and limit potential suture knot-related complications. Level of Evidence: Level V, expert opinion.

RESUMO

To describe the safety areas for placement of 5 anterolateral portals (anterior, anterior lateral, posterior lateral, proximal anterior medial and distal anterior medial portals) and 3 recently described medial portals (anterior medial, posterior medial and distal posterior medial portals) to provide topographical description of the safety of each. A descriptive, observational and cross-sectional study in which femoral triangle dissection was performed in 12 hips. 5 lateral portals and the 3 medial portals were placed. Clinically relevant neurovascular structures associated with each portal, were identified measured and documented. The lateral portal with the highest risk of injury to a nearby neurovascular structure was the anterior portal, the most adjacent to the femoral cutaneous nerve, 1.42 cm (±0.85) lateral to the portal. In the medial portals, the anterior medial portal has the narrowest margin in relation to the femoral artery, 2.14 cm (±0.35) lateral to the portal and medial to the obturator nerve by 0.87 cm (±0.62). The lateral portals have a higher safety margin; the portal with the most proximity to a neurovascular structure is the anterior portal, associated laterally with the femoral cutaneous nerve, presenting a higher risk of injury. Medial portals have a higher risk of injuring the femoral neurovascular bundle as well as the obturator nerve.

El objetivo fue describir las áreas de seguridad para la colocación de 5 portales estándar (portal anterior, anterolateral, posterolateral, portal anterior proximal medial y portal anterior distal medial) y 3 portales mediales emergentes (antero medial, portal posteromedial y posteromedial distal) para proporcionar una descripción topográfica de la seguridad de cada portal. Se realizó un estudio descriptivo, observacional y transversal, en la que se disecó el triángulo femoral de 12 caderas. Se colocaron los 5 portales laterales y los 3 portales mediales. Se documentó la medición de cada estructura neurovascular de relevancia clínica en relación a cada uno de los portales evaluados. En cuanto al portal de mayor riesgo entre los laterales, se encontró el portal anterior con mayor cercanía al nervio cutáneo femoral lateral (1,42±0,85 cm), ubicado lateral al portal. En los portales mediales el portal anterior medial tiene el margen más estrecho respecto a la arteria femoral (2,14±0,35 cm) lateral al portal, y medial el nervio obturador (0,87±0,62 cm). Los portales laterales tienen un amplio margen de seguridad, el portal con el margen más reducido es el portal anterior en relación al nervio cutáneo femoral lateral, presentando un elevado riesgo de lesionarlo, los portales mediales tienen un alto riesgo de lesionar las estructuras neurovasculares femorales y el nervio obturador.

RESUMO

PURPOSE: To evaluate the occurrence of adverse events and inflammatory reactions related to the use of biodegradable anchors. METHODS: A retrospective review of a consecutive series of arthroscopic shoulder procedures using biodegradable suture anchors performed by a single surgeon was undertaken. The database was purged of patient identifiers. The blinded data were analyzed for procedure type, anchor type and composition, associated procedures, and general demographic data. Anchor composition and number were recorded. A shoulder procedure after the index operation was considered an adverse event. The nature of these procedures was evaluated using medical records, operative images, and video, looking specifically for inflammatory reactions. Any anchor-related issues were documented. RESULTS: Three hundred sixty cases met the inclusion criteria. The procedure was a tendon repair (rotator cuff or biceps) in 265 cases and a labral repair (instability or SLAP) in 97, 2 of which were combined instability and tendon repairs. Nine different biodegradable anchors were identified, possessing 4 different polymer combinations. Adverse events (reoperations) were identified in 18 of 360 patients (5%): 13 tendon repairs and 5 labral/instability repairs. Only 2 were anchor related. In 1 tendon repair case, the anchor broke and an anchor fragment required removal. In 1 labral repair case, the anchor eyelet (a suture) loosened from the anchor body and eroded the humeral head. No cases of inflammatory synovitis were observed. No statistical difference in adverse event rates existed between tendon and labral repairs (P > .05). CONCLUSIONS: Anchor-specific adverse events occurred in 2 of 360 procedures (0.5%). One was anchor design related (the prominent head containing the suture eyelet broke off) in a poly-L-lactic acid (PLLA) anchor. One was anchor material related and occurred when the poly-levo (70%)/dextro (30%)-lactide anchor body reabsorbed, loosening the encased eyelet suture and allowing this suture to migrate into the joint. No inflammatory reactions were documented in the slowly degrading pure PLLA or more rapidly degrading biocomposite PLLA/ß-tricalcium phosphate-based anchors. LEVEL OF EVIDENCE: Level IV, retrospective review, therapeutic study.

RESUMO

A evolução do conhecimento acerca das funções dos meniscos e do tratamento das suas lesões, impulsionada pelo advento da cirurgia artroscópica, consagrou e popularizou a meniscectomia por esta via, por ser uma técnica menos invasiva, com menor morbidade e menores custos hospitalares, a ponto de torná-la, atualmente, a cirurgia ortopédica mais frequentemente realizada no mundo. Embora a maior parte dos pacientes submetidos a esta intervenção cirúrgica tenha resultados favoráveis e resolução rápida dos sintomas, percebe-se que parte considerável dos pacientes, especialmente os mais idosos, não apresenta uma evolução póscirúrgica satisfatória, apresentando piora dos sintomas e, eventualmente, necessitando de nova cirurgia. Partindo da hipótese que em determinados pacientes a meniscectomia, em vez de tratar, precipita e acentua um desequilíbrio biomecânico do joelho, o autor realizou estudo observacional prospectivo não-controlado com 86 pacientes de ambos os gêneros, com idade superior a 50 anos (média de 60,2 ± 7,1 anos), submetidos à meniscectomia artroscópica para tratamento de lesão do menisco medial de natureza degenerativa, com o objetivo de determinar variáveis demográficas, clínicas, anatômicas e cirúrgicas relacionadas aos resultados desfavoráveis. As avaliações funcionais pré e pós-operatórias foram realizadas utilizandose o Índice do KOOS (Knee Injury and Osteoarthritis Outcome Score), aplicado a todos os pacientes antes da cirurgia e 60 meses depois. Após análise estatística dos resultados obtidos, o autor verificou que 10 fatores podem ser considerados preditivos das meniscectomias mediais artroscópicas neste grupo etário, sendo quatro fatores fortemente associados aos resultados desfavoráveis: lesão da raiz posterior do menisco medial, dor pré-operatória intensa, claudicação antes da cirurgia e tempo decorrido entre o início dos sintomas e a cirurgia; dois fatores foram considerados moderadamente associados aos resultados...

The evolution of knowledge concerning meniscal functions and the treatment of their injuries, boosted by the development of arthroscopic surgery, has established and popularized arthroscopic meniscectomy due to its less invasiveness, less post-operative morbidity and lower hospital costs, to the point it has become, nowadays, the most frequently performed orthopedic procedure in the world. Although the majority of patients undergoing this operation is quite pleased with the outcomes and with the prompt resolution of their symptoms, it is noticeable that a considerable amount of patients with meniscal injuries, mainly the older, does not have a satisfactory postoperative outcome, with worsening of symptoms after being operated on and occasionally requiring another surgery. Based on observations of his medical practice and on the assumption that meniscectomy, rather than treat, can hasten and accentuate a biomechanical imbalance of the knee in those patients, the author conducted an observational prospective uncontrolled study with 86 patients of both genders, aged over 50 years old (average 60.2 ± 7.1 years), who underwent arthroscopic meniscectomy for the treatment of degenerative medial meniscal lesions, aiming to determine demographic, anatomical, clinical and surgical variables related to poor outcomes. The functional pre and post-operative evaluations were performed using the KOOS index (Knee Injury and Osteoarthritis Outcome Score) applied to all patients before surgery and 60 months later. After statistical analysis of the results, the author found that 10 factors can be considered predictors of arthroscopic medial meniscectomy in this age group: four factors were strongly associated with unfavorable results - posterior root lesion of the medial meniscus, intense pre-operative pain, claudication before surgery and time elapsed between onset of symptoms and surgery; two factors were moderately associated with unfavorable results - bone marrow...

RESUMO

PURPOSE: The objective of this study was to compare the functional assessments of arthroscopy and open repair for treating Bankart lesion in traumatic anterior shoulder instability. METHODS: Fifty adult patients, aged less than 40 years, with traumatic anterior shoulder instability and the presence of an isolated Bankart lesion confirmed by diagnostic arthroscopy were included in the study. They were randomly assigned to receive open or arthroscopic treatment of an isolated Bankart lesion. In all cases of both groups, the lesion was repaired with metallic suture anchors. The primary outcomes included the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. RESULTS: After a mean follow-up period of 37.5 months, 42 patients were evaluated. On the DASH scale, there was a statistically significant difference favorable to the patients treated with the arthroscopic technique, but without clinical relevance. There was no difference in the assessments by University of California, Los Angeles and Rowe scales. There was no statistically significant difference regarding complications and failures, as well as range of motion, for the 2 techniques. CONCLUSIONS: On the basis of this study, the open and arthroscopic techniques were effective in the treatment of traumatic anterior shoulder instability. The arthroscopic technique showed a lower index of functional limitation of the upper limb, as assessed by the DASH questionnaire; this, however, was not clinically relevant.
