ABSTRACT Objective: To assess pain and function of the ankle in patients with injuries up to 1.5 cm diameter by the American Orthopaedic Foot and Ankle Society (AOFAS) score after arthroscopic treatment. Methods: The AOFAS scale was applied before and after arthroscopy, as well as the degree of subjective satisfaction of ambulatory patients. Patients with type I osteochondral injuries, acute trauma, using plaster, presenting lesions in other joints of the lower limbs and cognitive impairment that would prevent the application of the satisfaction questionnaire were excluded from the study. Statistical analysis was performed using unpaired t test with Welch correction, Mann Whitney test, and ANOVA, with Kruskal Wallis test and Dun test, considering p value lower than 0.05. Results: There was an increased AOFAS scores after arthroscopic treatment in 52 (94.5%) patients. The mean values of AOFAS score in 55 patients was 77.32 ± 6.67 points preoperative and 93.10± 8.24 points postoperative, with a mean variation of 15.8 points, p<0.001. Patients with stage II, III and IV injuries showed an increased AOFAS scores after arthroscopic treatment, p<0.001. No difference was found between medial and lateral injuries, p >0.05. Conclusion: Patients with stage II, III or IV osteochondral injuries of the talus of up to 1.5 cm diameter, whether medial or lateral, showed a significant improvement after arthroscopic treatment. Level of Evidence III, Retrospective Study.

OBJETIVO: Descrever uma técnica cirúrgica própria de descompressão artroscópica do nervo supraescapular (NSE) e avaliar seus resultados preliminares. MÉTODOS: 10 ombros de nove pacientes foram operados com uma técnica que utiliza portais diferentes das técnicas conhecidas, não usa tração e faz uso de materiais disponíveis na rede pública de saúde. RESULTADOS: 10 ombros de nove pacientes, sendo oito à direita e dois à esquerda, com média de idade de 69,5 anos, apresentaram mudança no escore UCLA de 11,7 para 26,1 no seguimento de 16,6 meses de pós-operatório. O questionário SF-36 teve pontuação de 122,9 e a escala bruta de dor de 88%. CONCLUSÃO: A descompressão artroscópica do NSE, segundo a técnica descrita, é reprodutível e menos traumática que as técnicas abertas. Os pacientes obtiveram melhora em vários parâmetros avaliados, principalmente no que se refere à dor. A descompressão artroscópica do NSE pode ser uma opção terapêutica para a patologia compressiva do NSE.

OBJECTIVE: To describe a specific surgical technique for arthroscopic decompression of the suprascapular nerve (SSN) and evaluate its preliminary results. METHODS: Ten shoulders of nine patients were operated using a technique with portals differing from the already-known techniques, which did not use traction and made use of materials available within the public healthcare system. RESULTS: Among the ten shoulders of nine patients, eight were right shoulders and two were left shoulders. The mean age was 69.5 years. The UCLA score increased from 11.7 to 26.1 points over the postoperative follow-up of 16.6 months. The SF-36 questionnaire score was 122.9 and the raw pain scale value was 88%. CONCLUSION: Arthroscopic decompression of the SSN in accordance with the described technique is reproducible and less traumatic than the open techniques. The patients achieved improvements in many of the parameters evaluated, particularly with regard to pain. Arthroscopic decompression of the SSN may be a therapeutic option for pathological compression of the SSN.

OBJETIVO: Realizar um levantamento retrospectivo das complicações mais frequentes da osteotomia tibial alta (OTA) em cunha de abertura medial. Esse procedimento vem a cada vez ganhando mais espaço no tratamento da artrose do joelho como uma das opções para pacientes jovens e ativos. Apesar dos resultados satisfatórios e seus benefícios, não é procedimento isento de complicações. MÉTODOS: Foram avaliados, retrospectivamente, todos os pacientes submetidos à OTA supratuberositária medial de cunha de abertura e fixados com placa do tipo Puddu, realizadas no período de 1 de outubro de 1987 a 30 de outubro de 2008, no Hospital e Maternidade Celso Pierro da Pontifícia Universidade Católica de Campinas (PUC-Campinas) e no Instituto Wilson Mello em Campinas. Foram excluídos pacientes com menos de 12 meses de seguimento, com prontuários incompletos, e os que tinham osteotomias bilaterais. RESULTADOS: Dos 67 casos avaliados, 55 eram do sexo masculino e 12 do feminino, com média de idade de 49,5 anos. O tamanho médio da cunha foi de 10,15mm e as complicações mais frequentes foram dor moderada e grave (13,04%), seguida de rigidez (6,52%), quebra de material (4,4%), fratura da cortical lateral intraoperatória (4,4%) e infecção (4,4%). CONCLUSÃO: Foi observado aumento de probabilidade de complicações quando há retardo na consolidação da osteotomia (p < 0,05). Foi possível concluir que as complicações da osteotomia de cunha medial são mais frequentes quando há associação de retardo de consolidação.

OBJECTIVE: To retrospectively survey the most frequent complications from medial opening wedge high-tibial osteotomy. This procedure is becoming increasingly important in treating knee arthrosis, as one of the options for young and active patients. Despite satisfactory results and its benefits, it is not a complication -free procedure. METHODS: All cases of medial opening wedge high-tibial osteotomy above the tibial tubercle with fixation using a Puddu plate that were performed at the Celso Pierro Hospital and Maternity Hospital, Pontifical Catholic University of Campinas (PUC -Campinas) and the Wilson Mello Institute, Campinas, between October 1, 1987, and October 30, 2008, were evaluated retrospectively. Patients with less than 12 months of follow-up or incomplete medical files, and those who underwent bilateral osteotomy, were excluded. RESULTS: Out of the 67 cases evaluated, 55 were males and 12 were females, with a mean age of 49.5 years. The mean wedge size was 10.15 mm and the most common complications were moderate to severe pain (13.04%), stiffness (6.52%), material breakage (4.4%), intraoperative fracture of the lateral cortical bone (4.4%) and infection (4.4%). It was observed that patients with delayed consolidation of the osteotomy had a greater chance of presenting complications (p < 0.05) . CONCLUSION: Complications from medial wedge osteotomy are more frequent when associated with delayed consolidation.
