Knee arthroscopy in patients over 64 years suffering from primary gonarthrosis

OBJECTIVES: to evaluate the results of the arthroscopic surgical techniques in patients with primary gonarthrosis older than 64 years. METHODS: an analytical observational study was carried out in 40 patients older than 64 years treated arthroscopically with the diagnosis of primary gonarthrosis, at the Manuel Ascunce Domenech University Hospital in the city of Camagüey from October 2012 to May 2019. The research has a level of evidence IV recommendation D. RESULTS: the average age of the 40 patients studied was 69,6 years, with a predominance of female to male, with a ratio of 3 to 1. Tricompartmental disease predominated in most patients as well as grade IV according to the Outerbridge RE classification. The cartilage and associated meniscus injuries predominate. Grades III and IV of the Kellgram JH and Lawrence JS classification were the most found. The most commonly used arthroscopic treatments were debridement and partial meniscectomy. Statistical significance between a before and after was detected. CONCLUSION: the results of the investigation show that the procedures performed through the arthroscopic route for patients with primary gonarthrosis over 64 years of age are effective in more than half of the patients.
