The epidemiology of patellofemoral pain in Majmaah, Saudi Arabia

Abstract

Patellofemoral Pain (PFP) is frequently described as clinical knee pain influencing adolescents and physically active adults; however, prevalence and risk factors in a large-scale population is not well established. This study aimed to investigate the prevalence of PFP in Majmaah, Saudi Arabia; and to interpret the influence of factors such as age, gender and BMI on the prevalence of PFP. Two hundred and forty-eight subjects including males and females were assessed in this study. A crosssectional study was performed in Majmaah Governorate, and surrounding cities, Saudi Arabia. The prevalence of PFP was considerably high among females (72.3%), while it was 27.7% among males. Moreover, the age was a significant predictor for PFP [OR=1.04, 95% CI-1.01-1.07], while the gender and BMI were not significant predictors. Based on these results, PFP is a commonly reported knee condition among adolescents. Apart from gender factor, overweight persons appear to be more liable to develop PFP. Moreover, increasing age is strongly associated with increasing risk of PFP.

Prevalence of Patellofemoral Pain and Knee Pain in the General Population of Saudi Arabia

“…The use of pain medications for knee pain by adolescents was reported by 21%, and knee-related symptoms were the most consistently linked factor to the usage of pain medications [ 8 ]. A Saudi study looked at the prevalence of PFP in Majmaah, Saudi Arabia [ 9 ]. Females had a higher prevalence of PFP (72.3%), whereas males had a lower prevalence of (27.7%).…”

“…Females had a higher prevalence of PFP (72.3%), whereas males had a lower prevalence of (27.7%). Furthermore, age was a significant predictor of PFP, while neither gender nor BMI was a significant predictor [ 9 ].…”

“…Little research has looked at data from general populations. A previous local study conducted in Saudi Arabia focused on the prevalence of PFP in a specific region [ 9 ]. However, there is no regional study investigating this issue on a larger scale in different regions of Saudi Arabia.…”

Knee Injury and Osteoarthritis Outcome Score Patellofemoral Questionnaire: Psychometric Properties among Females of Kingdom of Saudi Arabia

“…The PFJ-OA is evident in 20 to 30% of adult people aged 26 to 50 years having longstanding patellofemoral (PF) pain, and females are the primary victims of this [11,12]. One study concluded that the PFJ-OA is very common in Saudi patients [13] and more prevalent in Saudi Arabian females [14]. Valgus deformity will accelerate lateral PFJ-OA along with patellar dysplasia patella or tibial malrotation and direction or force of the quadriceps femoris [15].…”

“…Moreover, the KOOS-PF concept of cross-cultural validation is ongoing in several languages across the globe, and this questionnaire has been validated in the Arabic language among male subjects [20]. To better serve the people of Kingdom of Saudi Arabia (KSA) diagnosed with the PFJ pain, which is more common in Saudi females [13,14], and help the patients better express their symptoms in their mother tongue [21] thus mandated the need to validate it in Arabic among females. Therefore, the objective of the study was to translate, cross-culturally adapt and validate the psychometric properties of KOOS-PF among females (Ar-KOOS-PF-F) of KSA.…”
