I have studied your case.
According to your symptoms and findings there is osteoarthritis
of your knee.
You can start cartilage
protecting medication like chondritin sulphate, that you need to take for couple of months.
If required MRI knee can be done and if there is severe destruction of menisci then arthroscopic shaving can be done.Physiotherapy
will help, along with knee exercises.
Exercises of shoulder will help to improve post op results
