Introduction:

Gonarthrosis is a common entity that especially affects people over 60 years of age. For its treatment, conservative and surgical modalities are combined, and within the latter, those carried out by the arthroscopic route.

Objective:

To evaluate the results of arthroscopic surgical techniques in patients with primary gonarthrosis older than 64 years of age.

Methods:

A pre-experimental design study (pre-test-post-test) was carried out in 40 patients older than 64 years treated arthroscopically due to the diagnosis of primary gonarthrosis, at Manuel Ascunce Domenech University Hospital in Camagüey from October 2012 to May. of 2019. The research has a level of evidence IV and recommendation D.

Results:

The average age of the patients studied was 69.6 years, with a predominance of females, and a ratio of 3:1. Tricompartmental involvement prevailed in most of the patients, as well as grade IV according to the Outerbridge classification. Associated cartilage and meniscus injuries predominated. The most used arthroscopic treatments were debridement and partial meniscectomy. Statistical significance was detected between before and after.

Conclusions:

The results of the investigation show that the procedures carried out through the arthroscopic route in patients older than 64 years of age with primary gonarthrosis are effective in more than half of the patients.
