PDPS is more severe at smaller knee flexion angles and faster onset, leading to higher pain and disability. Targeting these factors may improve treatment and long-term outcomes.
A recent study has uncovered that patellofemoral pain (PFP) is more severe at smaller knee flexion angles and with faster onset, leading to increased pain and disability. The research published in “BMJ Open” aimed to explore the differences between individuals with and without pain during prolonged sitting (PDPS), identify the knee flexion angle that triggers pain, and understand the time it takes for the pain to start and subside.
The study involved 87 participants, 70% female, with an average age of 22 years. Volunteers were requested to fill an online questionnaire that measured pain degree and other related factors. The findings revealed that 72% of participants reported experiencing PDPS. Those with PDPS were more likely to experience bilateral PFP symptoms (71% vs 46%) and scored 12 points lower on the Anterior Knee Pain Scale (AKPS), indicating a higher level of disability. Most participants reported experiencing PDPS at knee flexion angles of 90 degrees or greater, with a median time of 16-20 minutes for pain onset and 6-10 minutes for pain disappearance.
Notably, the study also found that participants who experienced PDPS at smaller knee flexion angles reported markedly higher visual analog scale for worst pain (VAS-W) and VAS-W sitting scores compared to those at greater angles. Additionally, those with a faster onset of PDPS also illustrated higher pain levels compared to those with a slower onset. This study highlighted the impact of knee flexion angles and onset speed on the severity of PDPS and suggested that further research is needed to explore the underlying mechanisms of this condition.
