Factors Associated with Osteoarticular Complications such as Knee Pain in Hemodialysis Patients: an analytical cross-sectional at the National Teaching Hospital in Cotonou, Benin

Abstract

Context and objective. Hemodialysis patients develop osteoarticular complications such as gonathrosis. The aim was to assess the frequency and factors associated with knee pain in hemodialysis patients. Methods. This was a cross-sectional study conducted from July 1 to September 30, 2023 at the CNHU-HKM in Cotonou, Benin. Sampling was exhaustive. The dependent variable was the presence of knee pain. Data were collected, entered, and analyzed at a significance level of p<0.05. Results. A total of 123 chronic hemodialysis patients were included in the study. The mean age was 60.65 ±13.19 years and the sex ratio was 1.4. Knee pain was present in 55.3% of patients, 51.5% of whom had pain in the medial aspect of the knee. Among the patients with pain, 69.4% lived in a permanent pain psychosis. The main associated factors were red meat consumption (p=0.001), ORa 2,2, IC 95% [1.16-3.21],) and the duration of dialysis (p=0.02) ORa 3.6, IC95% [1.12-4.54]. Conclusion. Knee pain is frequent in hemodialysis patients and is associated with several factors. Early treatment is essential to avoid disability.
