Influence of patellofemoral joint reaction force changes at small knee flexion angles on patellofemoral pain during single limb landing in active females (pubmed.ncbi.nlm.nih.gov)

• Increased PFJRF at small knee flexion angles correlates with pain
• Single limb landing is a high-risk scenario for patellofemoral pain
• Controlling knee flexion may help reduce pain

"This study examines the relationship between patellofemoral joint reaction force (PFJRF) at small knee flexion angles and patellofemoral pain during single limb landing in active females. Increased PFJRF at low flexion angles was associated with pain, highlighting the importance of knee flexion control in rehabilitation."
