Presenting the arthroscopic treatment by Tight Rope - Arthrex® system for acute acromioclavicular dislocation and to evaluate results obtained with this procedure. Methods: Between August 2006 and May 2007, 10 shoulders of 10 patients with acute acromioclavicular dislocation were submitted to arthroscopic repair using the Tight Rope - Arthrex® system. Minimum follow-up was 12 months, with a mean of 15 months. Age ranged from 26 to 42, mean 34 years. All patients were male. Radiology evaluation was made by trauma series x-ray. The patients were assisted in the first month weekly and after three months after the procedure. Clinical evaluation was based on the University of California at Los Angeles (UCLA) criteria. Results: All patients were satisfied after the arthroscopic procedure and the mean UCLA score was 32,5. Conclusion: The arthroscopic treatment by Tight Rope – Arthrex® system for acute acromioclavicular dislocation showed to be an efficient technique.

To present the arthroscopic surgical technique and the evaluation of the results from this technique for treating elbow stiffness. Methods: Between April 2007 and January 2010, ten elbows of ten patients with elbow stiffness underwent arthroscopic treatment to release the range of motion. The minimum follow-up was 11 months, with an average of 27 months. All the patients were male and their average age was 32.8 years (ranging from 22 to 48 years). After the arthroscopic treatment, they were followed up weekly in the first month and every three months thereafter. The clinical evaluation was made using the criteria of the University of California at Los Angeles (UCLA). Results: All the patients were satisfied with the results from the arthroscopic treatment. The average UCLA score was 33.8 points. Conclusion: Arthroscopic treatment for elbow stiffness is a minimally invasive surgical technique that was shown to be efficient for treating this complication.

Objective: To present the surgical technique for the He-miCAP-Arthrosurface® system and evaluate our results from this technique for treating primary and/or secondary shoulder osteoarthrosis. Method: Between June 2007 and June 2009, 10 shoulders of 10 patients (nine with primary osteoarthrosis and one with avascular necrosis of the humeral head) underwent surface arthroplasty using the HemiCAP-Arthrosurface® system to correct the problem. The follow-up time ranged from six to 29 months (mean of 17 months). The patients’ ages ranged from 62 to 73 years (mean of 67.5 years). Six patients were female and four patients were male. The patients were followed up weekly for the first month after the surgical procedure and every three months thereafter. The clinic evaluation was done using the criteria of the University of California at Los Angeles (UCLA) and a visual analogue pain scale. Results: All the patients said that they were satisfied with the results from the surgical treatment, with a mean UCLA score of 30 points and a mean analogue pain score of two points. Conclusion: The HemiCAP-Arthrosurface® system for shoulder surgery for a specific group of patients is a technique that preserves the bone stock with good functional and antalgic results.

Objetivo: Apresentar a técnica cirúrgica artroscópica pelo método "Tight Rope" e a avaliação dos resultados com esta técnica no tratamento da luxação acrômio-clavicular aguda. Métodos: entre agosto de 2006 e maio de 2007, 10 ombros de 10 pacientes com luxação acrômio-clavicular aguda foram submetidos a tratamento artroscópcio pela técnica Tight Rope-Arthrex ® . O seguimento mínimo foi de 12 meses, com média de 15 meses. A idade variou de 26 e 42 anos com média de 34 anos. Todos os pacientes eram do sexo masculino. Todos os pacientes foram atendidos na fase aguda da lesão sendo avaliados por radiologia simples (série trauma). Os pacientes foram acompanhados semanalmente no primeiro mês e a cada três meses após o procedimento artroscópico. A avaliação clínica foi feita por meio dos critérios da University of Califórnia at Los Angeles (UCLA). Resultados: Todos os pacientes operados agudamente encontravam-se satisfeitos com os resultados do tratamento cirúrgico artroscópico com uma média de 32,5 pontos na escala de avaliação da UCLA. Conclusão: O tratamento artroscópico da luxação acrômio-clavicular aguda pelo método "Tight Rope" é uma técnica cirúrgica minimamente invasiva que mostrou-se eficiente para o tratamento destas lesões.
