Hi,
First of all thank you for providing the brief history of you.
I am sorry to hear about all these trouble getting towards you.
Let me focus on what i can guide you which can help you fight the trouble you are facing physically.
You mentioned you have pain in the knee joint due to
arthritis.
Lets look into the deep of it. You had ACL and
Hamstring issue.
Now arthritis is a ageing process for which no one can reverse it except your own body. Human body is a self healer and what medicine can provide is to support the systems which can help it to heal and allow physical status of the body.
Since you had ACL and hamstring repair, Your need to focus on One simple thing now, that is strengthening the body as a whole
unit. For which you may need some proper guidance, assistance and support.
You need to start slowly first doing the ankle toe movements, which will help to get the strength in the muscles of the leg and also the vascular system of the below knee will improve.
Dont get bore here.. there is still more to focus here.
Look for lying down on your back and do straight leg raise and hold for as long as you can as it will be isometrics and isometrics give abundant strength in the muscles.
Next you need to do not only for the leg affected but also the leg which is not affected as well. Since body works as a unit and the unit has to be gathered with each way.
same leg lifting you can do by lying down on your side and lift it up sideways which will strengthen the side of the thigh muscles.
Then proceed onto strengthing the back of the thigh and the inner of the thigh. all the exercises you can either learn from a physical therapist of either you can learn from research articles available on google. as in the research articles they mention the complete detail of the same without anything missing.
Strengthen your core muscles and also strengthen your spinal muscles as well.
Do try to achieve plank exercises for 3 minutes for a minimum and go upto 10 minutes.
Perform reverese walking and see to that you strength the last 1/3 of the the quadriceps muscle.
Strengthening the lower body as a whole on both sides will help you alot by fighting the arthritis issue.
Try to perfrom knee ROM exercises as it is a must to have a complete ROM in each joint.
Do single leg standing and sitting up exercises which will give you immense strength as well..
This is just the beginning.
Once you master in this will teach next.
I have seen many cases with OA knee and my all cases are above 60. All does well and do on a regular basis running without any pain and aches.
With the grace of god i wish you a good health
