Observations

Task 1 (2.5/3)
You have shared a good knowledge about knee osteoarthritis, and it's stages. But you have to add the types, symptoms and causes too of knee OA to better explain this to other users. I bit more depth require to complete the answer. I appreciate your effort.

Task 2 (2.5/3)
In the second question, you tell us about how you assess the patient of knee OA by doing the physical examination, history taking, investigations of patients. But it would be better if you add 1 or 2 special tests to confirm the diagnosis. Good.

Task 3 (3.8/4)
You try the heel slides, calf & hamstring stretch, William Flexion ( knee to chest exercise), Knee Isometric ( Knee flexion ). But while performing exercises calf & hamstring stretch you have to check your flexibility level if you feel unbearable stretch or pain try to perform it in less range as we can't do daily activities our body feel pain while performing such exercises. Remember always apply heating pad to relax your muscles before performing these exercises. I appreciate your efforts.

Overall you made a good attempt to answer all the questions. I appreciate your efforts. But next time try to avoid the above written suggestions. Keep learning and try to implement your knowledge to the people suffering from any knee Osteoarthritis. Thank you.
