Patients enrolled in this on-going 10 year study at Rebound, who had already filled out a 3 month post-operation questionnaire were chosen to provide certain pieces of data, which the doctors would be able to see. These pieces of data included their pre-OP and 3 month Range of Motion results, their pre-OP and 3 month Flexion Contracture, their pre-OP and 3 month Knee Society Scores (which asks questions referring to how far they can walk, how they get up and down stairs, and if they need any kind of support when they walk), and their satisfaction with their artificial joint at 3 months post-surgery. . . . محمد فهد المسعود 431102617. عاصم فهد . الدهيش. 430106507. عوض . عبدالله. . الحربي 431102322. Introduction. the immune response uses multiple strategies to reduce damage to self by turning off responses when pathogen is cleared and avoiding reactions to self antigens. However, these checks and balances can break down, leading to immune-mediated reactions that are more detrimental than protective. . Level 1 – Chapter 5. Objectives.
