Abstract

GRENIER-ALMEYDA, GE. Comparative study to evaluate the effectiveness of treatment with platelet-rich plasma and NSAIDs in grade I-II gonarthrosis. Acta ortop. mex [online]. 2023, vol.37, n.2, pp.64-70.  Epub May 06, 2024. ISSN 2306-4102.  https://doi.org/10.35366/112984.

Introduction:

population aging is a worldwide demographic phenomenon of the last thirty years. This increase in life expectancy leads to an increase in the incidence of degenerative diseases, mainly gonarthrosis. According to World Health Organization (WHO) estimates, 10% of the population over 60 years of age suffers from osteoarthrosis, and 40% of the population over 70 years of age suffers from gonarthrosis, Figures that could increase in the next decade. Approximately 80% of people over 65 years of age present radiographic changes with evidence of gonarthrosis, being 10-25% of the reason for medical visits at the first level of care. Treatment with intra-articular platelet rich plasma has proven to be an effective therapeutic alternative.

Material and methods:

a prospective, quasi-experimental, non-randomized study was carried out to compare the behavior of grade I and II gonarthrosis in 140 patients diagnosed clinically and radiologically. Separated into two groups of patients, the first group treated with non-steroidal anti-inflammatory drugs (NSAIDs) and the second group treated with intra-articular infiltration with platelet-rich plasma (PRP). The same was carried out in the Specialties Clinic No. 3 of the Cuauhtémoc Health Jurisdiction, in the orthopedics office during the year 2020. Descriptive statistics were analyzed through the elaboration of a frequency Table that allowed us to calculate the mean and standard deviation, and inferential statistics were analyzed through the χ2 test.

Results:

the age group most affected by gonarthrosis is 60 to 69 years of age with 43.5% of the total number of patients, being the female sex the most affected with 33.5%. Most of the patients had a body mass index that placed them as overweight and obese with 39 and 53% respectively. Pain evolved towards improvement in 92% of patients treated with platelet-rich plasma (PRP) and in 25.7% of patients treated with nonsteroidal anti-inflammatory drugs. The functional capacity of the knee joint recovered in 97% of the patients treated with PRP and in 35.7% of those treated with nonsteroidal anti-inflammatory drugs.

Conclusions:

treatment of grade I and II gonarthrosis with intra-articular platelet-rich plasma is more effective than treatment with non-steroidal anti-inflammatory drugs.

Keywords : gonarthrosis; treatment; platelet-rich plasma; non-steroidal anti-inflammatory drugs.
