“…The primary issue is the viability and denaturation of the remaining articular cartilage after thermal treatment. 7,[11][12][13][14][15][16] Recently, there has been increased focus on the various techniques used to evaluate the cartilage after treatment. [17][18][19] This has included histological techniques such as hematoxylin and eosin staining and confocal laser microscopy.…”

The purpose of this study was to create a controlled partial thickness cartilage lesion in a sheep model, and to provide a foundation to study the natural history of the progression of this lesion. Twenty-eight sheep divided into four groups (1, 12, 24, and 52 weeks, n ¼ 7/group) were used in this study. In one stifle, a mechanical tool was used to create a 200 mm partial thickness lesion (1.5 Â 1.5 cm 2 ) on the medial femoral condyle via arthroscopy. Joint fluid was drawn presurgery and after euthanasia for analysis of collage II 3/4 C long (C2C). After euthanasia, the condyle was analyzed by gross appearance, confocal laser microscopy (CLM) for cell viability, scanning electronic microscopy (SEM) for surface roughness, Artscan for cartilage stiffness, and histology for cartilage morphology. The gross appearance of the treated area appeared rough, soft, and swollen compared to untreated control over time. CLM demonstrated that the depth of cell death increased to 590 mm at 52 weeks after surgery. SEM demonstrated that the treated area became more irregular over time. Stiffness of the treated area was significantly less than control by 12 weeks after surgery. Histologic analysis demonstrated that the 12, 24, and 52 week groups had significantly poorer histologic scores than the 1 week group. Joint fluid analysis demonstrated that the treatment group at 1 week had significant higher levels of C2C than the pretreatment baseline data. The results of this study demonstrated that partial thickness injury of cartilage continued to propagate and degenerate over time in this sheep model. Options for the prevention or treatment of this lesion may be tested using this model in the future. ß

“…Es impensable pensar que la rápida mejora sintomática de los pacientes en los primeros 7-10 días se deba a la revascularización y reorganización del colágeno. Por tanto, la hipótesis de los autores es que esta rápida reducción del dolor, incluso en el postoperatorio inmediato, se deba a un efecto antinociceptivo, similar al producido por las ondas extracorpóreas de choque [30][31][32][33][34][35] . El uso de la terapia de las ondas de choque extracorpóreas (ESWT) o el uso de la energía de pulsos de radiofrecuencia 36 …”

ReSuMenLas lesiones del tendón de Aquiles son un motivo frecuente de consulta en el ámbito de la podología y de la cirugía del pie y tobillo. El dolor del tercio medio del tendón es un problema habitual en corredores, pero también se ve en pacientes sedentarios. El término correcto para referirnos a esta lesión es el de tendinopatía aquílea no insercional. Existen numerosos tratamientos que intentan disminuir el dolor y mejorar la función del tejido lesionado. Los medios conservadores suelen tener buenos resultados, pero existe un porcentaje de pacientes que precisan cirugía. Presentamos una técnica poco invasiva para esta patología en la que utilizamos un dispositivo de radiofrecuencia para tratar la tendinosis. Palabras clave: tendón de aquiles; tendinosis; radiofrecuencia. AbStRACtAchilles tendon injuries are a common disease in podiatric and foot and ankle surgery consultation. Midportion pain is a frequent problem in runners but could be seen in sedentary people too. Correct term for this condition is non insertional Achilles tendinopathy. There are many treatment options that try to reduce the pain and improve the function of damaged tissue. Conservative treatments usually have good results but there are some cases that could need surgery. We present a minimally invasive technique using a radiofrequency microdebrider to treat the tendinosis. Key words: achilles tendon; tendinosis; radiofrequency.Sumario: 1. Introducción, 2.

“…This appears to be due to the fact that each investigation used a different tissue model, RF delivery system, equipment setting, RF delivery technique (i.e., with regard to treatment time and use of the RF electrode in a contact vs. noncontact manner), and method of histological evaluation [9,10,23].…”

“…To perform thermal chondroplasty using electrosurgical equipment it is recommended to directly contact the tissue using the monopolar RF electrode, while it is recommended to barely contact the tissue (i.e., a "noncontact" technique) using the bipolar RF electrode [9,19,22]. Additionally, the tip of the RF electrode should be applied over the treatment area with continuous, small strokes or a "painting" motion to avoid prolonged contact with the tissue [22].…”

This in vitro investigation characterized temperature changes associated with radiofrequency (RF) energy induced heating of bovine articular cartilage using temperature-controlled, monopolar (Vulcan RF system and Vulcan, TAC-S Electrothermal Probe) and bipolar (VAPR II RF system and VAPR TC RF electrode) electrosurgical equipment. The RF generators were used at the same setting (set temperature 70 degrees C; 30 W). The cartilage tissue sample was placed in a saline bath maintained at room temperature. Temperatures were recorded using fluoroptic thermometry at the RF electrode-tissue interface at 1-s intervals before, during deliver of RF energy (1- and 2-s), and after (1- to 3-s). For both electrosurgical systems the mean RF electrode-tissue interface temperatures were significantly ( P<0.05) higher than the mean baseline value during delivery of RF energy (monopolar, highest mean temperature, 65.7 degrees C; bipolar, highest mean temperature, 54.1 degrees C). In general, during and after the deliver of RF energy, the monopolar RF system produced tissue temperatures that were significantly ( P<0.05) higher than those produced by the bipolar RF system. Neither electrosurgical system exceeded the set temperature of 70 degrees C. These findings provide basic tissue temperature characteristics for the newly developed, temperature-controlled RF devices applied to articular cartilage.
