Abstract
BackgroundIn Africa, primary hip osteoarthritis seems to be less frequent than in Europe. Sickle cell disease is responsible for aseptic osteonecrosis of the femoral head associated with secondary hip osteoarthritis. Very little evidence is available on the influence of aetiology (primary and secondary) and radiographic status on pain and disability in a Beninese population with hip osteoarthritis.ObjectivesThe aim of this study was to compare the impacts of aetiology and radiographic status on pain, disability and quality of life in a Beninese population with hip osteoarthritis.MethodThis was a descriptive cross-sectional study, including participants recruited in the Clinic of Physical Medicine and Rehabilitation at the National Teaching Hospital in Cotonou.Assessment was based on the International Classification of Functioning, Disability and Health model. The main outcomes were severity of osteoarthritis, pain, range of motion, muscle strength, gait speed and quality of life. Statistical comparisons between the aetiologies were performed using a t-test or rank sum test. One-way analysis of variance was used to test the effect of radiographic status.ResultsForty-nine participants (26 women and 23 men; mean age [standard deviation] 40.5 [17.9] years) were recruited. According to the aetiology (59.2% and 40.8% of primary and secondary osteoarthritis, respectively), there were no significant differences for any of the outcomes. Grades I, II, III and IV osteoarthritis were observed in 22.4%, 14.3%, 26.5% and 36.7% of the participants, respectively. Participants with grade IV osteoarthritis were more affected than those with grades I, II and III based on the Kellgren and Lawrence classification.ConclusionAetiology did not influence pain, gait speed or quality of life. Participants with grade IV osteoarthritis had more pain, were more limited in walking and had a more impaired quality of life.
Highlights
Osteoarthritis is a chronic condition that affects 11% of the general adult population and is the most common form of arthritis (Pereira et al 2011)
As demonstrated by Dowman et al (2012), Hip osteoarthritis (HOA) is often seen as a minor health problem and has been neglected in research and resource allocation throughout Africa despite potential related disabilities and decreased quality of life (QoL)
This study focused on participants with HOA in the Republic of Benin, a West African country
Summary
Osteoarthritis is a chronic condition that affects 11% of the general adult population and is the most common form of arthritis (Pereira et al 2011). As demonstrated by Dowman et al (2012), HOA is often seen as a minor health problem and has been neglected in research and resource allocation throughout Africa despite potential related disabilities (such as abnormal gait patterns and lower physical function) and decreased quality of life (QoL). According to their aetiologies, there are two types of HOA: primary and secondary. Its aetiologies include congenital hip abnormalities, metabolic defects, infections and blood disorders such as sickle cell disease (Kpadonou et al 2011; Oniankitan et al 2009; Ouedraogo et al 2015). Very little evidence is available on the influence of aetiology (primary and secondary) and radiographic status on pain and disability in a Beninese population with hip osteoarthritis
