Patellofemoral joint pain (PFJP) is common in adolescents and adults, associated with a high prevalence of chronicity and has similar clinical features to early knee osteoarthritis. Physical impairments and functional deficits associated with PFJP are well documented and may detrimentally impact quality of life (QOL). However, a large body of literature related to the impact of PFJP on QOL has not previously been reviewed or synthesised.
To review and synthesise QOL outcomes for young adults and adolescents with PFJP and summarise the impact of interventions on QOL.
We systematically identified all studies reporting QOL in individuals with PFJP, with a mean age under 50 years. Data extracted included knee-related and health-related QOL outcomes. Studies were methodologically appraised and comparisons made with population norms and healthy control groups.
Eighteen studies reported QOL in 896 individuals with PFJP. Knee-related QOL measured by the Knee injury and Osteoarthritis Outcome Score (KOOS-QOL) in people with PFJP (mean +/- SD: 49 ± 21 to 78 ± 18) was lower than healthy adolescent controls (98±6 to 99±3) and young adult population norms (80±23 to 84±20). Physical component scores (PCS) from the SF-36 in people with PFJP (37±4 to 55±16) were lower than population norms (49±9 to 55±6). Physiotherapy intervention significantly improved KOOS-QOL scores by 6-12 points in adolescents with PFJP; and PCS scores by 8-9 points in adults with PFJP.
Significance of findings to allied health
QOL is clearly impaired in adolescents and adults with PFJP and may be improved through physiotherapy management.
