Pain Characteristics among Patients with Knee Osteoarthritis in Aden, Yemen

Abstract

Knee osteoarthritis in adults is very common and is one of the most common causes of joint pain. The aim of the
study was to describe the demographic characteristics and to analyze the clinical finding. It was a retrospective study
conducted in Aden during the years 2015 to 2017. Data was obtained from patients’ charts and presented as
frequencies, percentages, means and standard deviation. Significance was considered at P value < 0.05. The patients
were 367, (males 44.4% and females 55.6%). The older patients (≥ 55 years) were (77.1%). About (39.5%) patients
were mostly suffered from right knee osteoarthritis, (25.1%) suffered from left knee and (35.4%) patients have both
knee osteoarthritis. Knee pain was mild in (61%) patients and in (30%) patients was moderate. Female to male ratio
was 1.3:1 and their mean age was 61.0 ± 9.5 years (age ranged between 35 and 83 years). There was a significant
correlation between mean ages of both gender (p = 0.001).The mean uric acid was 6.9 ± 1.6 mg/dL and the
relationship between means in both gender was significant (p = 0.000). Patients were higher in the age group ≥ 55
years. Most of right knee osteoarthritis were in females (28.6%), while the bilateral osteoarthritis were predominant
in males (22.1%) (P = 0.000).The relationship between severity of knee pain and side involvement of the knee joint
was highly statically significant (P = 0.000). Further prospective studies are needed.
